chapter 4 power tools and equipment quotation

Keep tools organizedA technician has hundreds of different tools. For the tools to be locatedquickly, they should be neatly arranged. Thereshould be a place for every tool, and every toolshould be in its place. If tools are just thrown intothe toolbox, time and effort are wasted "diggingand searching" instead of fixing the vehicle.

Keep tools cleanWipe tools clean and dry aftereach use. A greasy or oily tool can be dangerous!It is very easy to lose a grip on a dirty tool, cutting or breaking a finger or hand.

Use the right tool for the jobEven though several different tools may be used to loosen a bolt,usually one will do a better job. It may be faster,grip the bolt better, be less likely to break, orrequire less physical effort. A good technicianknows when, where, and why a particular toolwill work better than another. Keep this in mindas you study automotive tools.

Select the right tool for a given job.Maintain and store tools properly.Use hand tools safely.Correctly answer ASE certification test questionsreferring to hand tools.Professional auto technicians invest thousands ofdollars on tools, and for good reason. It is almost impossible to do even the simplest auto repair without usingsome type of tool. Tools serve as extensions to parts ofthe human body. They increase the physical abilities offingers, hands, arms, legs, eyes, ears, and back. A wellselected set of tools speeds up repairs, improves workquality, and increases profits.This chapter will cover the basic hand tools commonly used in the shop. Specialized hand tools are covered in later chapters. Use the index to locate these toolsas needed.

Tech Tip!The time spent maintaining your tools andtoolbox is time well spent. Well-organizedtools will save time on each job and help youget more work done. Unorganized or poorlymaintained tools will hurt your on-the-jobperformance.

Tech Tip!It is very frustrating trying to fix a vehicle withoutthe right tools. It can be like trying to "fight aforest fire with a squirt gun"impossible!Invest in a complete set of quality tools.

Purchase quality toolsWith tools, you usuallyget what you pay for. Quality tools are lighter,stronger, easier to use, and more dependable thanoff-brand, bargain tools. Many manufacturers ofquality tools provide guarantees. Some are forthe lifetime of the tool. If the tool fails, the

Tool StorageA toolbox stores and protects a technician"s toolswhen not in use. There are three basic parts to a typicaltoolbox, Figure 3-1. These include:

The lower roll-around cabinet holds the bulky,heavy tools. Large power tools are normally kept in thispart of the box. Extra storage compartments can bebolted to the sides of the roll-around cabinet.Commonly used tools are normally placed in theupper tool chest. Being near eye level, tools can be easilyseen and reached without bending. This saves time andenergy, and increases production.The small carrying (tote) tray is for holding frequently used tools that are carried to the job. For example,if a technician frequently does brake repairs, all the special brake tools can be kept in the tray and taken to thevehicle more easily.

Toolbox OrganizationRelated tools are normally kept in the same toolboxdrawer. For example, various types of hammers may bestored in one drawer and all screwdrivers in another. Smallor delicate tools should not be kept with large, heavy toolsto prevent damage. Tool holders help organize small tools.These include small clip or magnetic racks, cloth or plasticpouches, or socket trays. They are often used to protecttools and to keep them organized by size. Holders alsoallow a full set of tools to be taken to the job.

Line WrenchesA line wrench, also called a tubing wrench or flarenut wrench, is a box-end wrench with a small opening orsplit in the jaw, Figure 3-4D. The opening allows thewrench to be slipped over fuel lines, brake lines, or powersteering lines and onto the fitting nut. A line wrench prevents damage to soft fittings.

Socket HandlesSocket handles fit into the square opening in the topof the socket. Several types are shown in Figure 3-7. Aratchet is the most commonly used and versatile sockethandle. It has a small lever that can be moved for eitherloosening or tightening bolts. A flex bar, or breaker bar,is the most powerful and strongest socket handle. Itshould be used when breaking loose large or extremelytight bolts and nuts. A speed handle is the fastest handoperated socket handle. After a bolt is loosened, a speedhandle will rapidly spin out the bolt.Extensions are used between a socket and its handle.See Figure 3-8A. They allow the handle to be placedfarther from the workpiece, giving you room to swingthe handle and turn the fastener. A universal joint is aswivel that lets the socket wrench reach around obstructions, Figure 3-8B. It is used between the socket anddrive handle, with or without an extension. Avoid puttingtoo much bend into a universal joint, or it may bindand break.

impact driver can be used to loosen extremely tightscrews. When struck with a hammer, the driver exertspowerful turning and downward forces. This is shown inFigure 3-12.When selecting a screwdriver, pick one that is wideand thick enough to completely fill the screw slot. If thescrewdriver is too large or too small, damage to thescrewdriver or screw may occur. Most screwdrivers arenot designed to be hammered on or pried with. Onlyheavy-duty screwdrivers with a full shank can withstandlight hammering and prying.

Locking pliers, or vise grips, clamp onto and hold apart, Figure 3-13E. This frees both hands to do othertasks. Because of their clamping power, vise grips cansometimes be used to unscrew fasteners with stripped orrounded heads. However, never use them on undamagednuts or bolts. Snap ring pliers have sharp, pointed tips forinstalling and removing special clips called snap rings. Apair of snap ring pliers is shown in Figure 3-13F.

Use a brass, plastic, or dead blow hammer onparts and tools that can be damaged by a steelhammer. Use a steel hammer only when maximum driving force is required.

round end for shaping metal parts, such as sheet metal orrivet heads.A sledge hammer has a very large head. Figure 3-14B.It is usually the heaviest hammer and produces powerfulblows. A sledge hammer is sometimes used to freefrozen parts.The brass has a soft, heavy head and is usefulwhen scarring the surface of a part must be avoided,Figure 3-14C. The relatively soft head deforms to protectthe part surface from damage.A plastic or rawhide hammer is light and has a softhead. Figure 3-14D. It is used where light blows areneeded to prevent part breakage or damage to surfaces onsmall and delicate parts.A rubber mallet has a head made of solid rubber,Figure 3-14E. It will rebound, or bounce, upon strikingand is not effective on solid metal parts. It is recommended on many sheet metal or plastic parts, such asgarnish molding and wheel covers.A dead blow hammer has a plastic-coated, metalface and is filled with small metal balls called lead shot.The extra weight prevents a rebound of the hammer whenstriking. The plastic coating prevents surface damage.

There is an old saying, "if you do the job right, youwill spend most of your time cleaning parts." Dirt is amajor enemy of a vehicle. One grain of sand can causea major breakdown by clogging a passage or scarring apart. Cleaning tools, such as scrapers and brushes, helpthe technician remove carbon, rust, dirt, grease, old gaskets, and dried oil from parts.Scrapers remove grease, gaskets, sludge, dried oil, andcarbon on parts. They are used on flat surfaces. Never scrapetoward your body. Keep your other hand out of the way.Brushes are used to remove light rust and dirt on parts. Theyare slow and should be used only when necessary.

Pickup and probing tools are needed when bolts,nuts, or other small parts are dropped and cannot bereached by hand. A magnetic pickup tool is a magnethinged to the end of a rod. It can usually be shortened orlengthened and swiveled to reach into any area. If a ferrous (iron) metal part is dropped, it will be attracted andstick to the magnet. Figure 3-23A.A finger pickup tool grasps nonmagnetic parts(aluminum, plastic, or rubber), which will not stick to amagnet, Figure 3-23B. A mirror probe allows you to

Workplace SkillsA properly designed tool acts as an extension ofyour body or mind. Tools are essential to the repair ofany motor vehicle. For this reason, you should learnabout new tools as they are developed. A good tool isa wise investment that will help you be a more productive, successful technician.

ActivitiesChapter 31. Collect automotive catalogs and create a list ofhand tools needed to equip an automotive shop.Provide an estimate of what it will cost to purchase the tools.2. Discuss tool safety with your instructor. Preparea list of safety regulations for your shop area.

After studying this chapter, you will be able to:List the most commonly used power tools andequipment.Describe the uses for power tools and equipment.Explain the advantages of one type of tool overanother.Explain safety rules that pertain to power toolsand equipment.Correctly answer ASE certification test questionsthat require a knowledge of power tools andequipment.

To be a productive technician in today"s automotiveservice facility, you must know when and how to usepower tools and equipment. Power tools are tools drivenby compressed air, electricity, or pressurized liquid. Theymake many repair operations easier and quicker. Largeshop tools, such as floor jacks, parts cleaning tanks, andsteam cleaners, are called shop equipment.This chapter discusses properly selecting and usingcommon power tools and shop equipment. They can bevery dangerous if misused. Always follow the operatinginstructions for the particular tool or piece of equipmentbefore use. If in doubt, ask your instructor for a demonstration. Specialized power tools and equipment are covered in later chapters. Refer to the index to find moreinformation on them as needed.

Air HosesFlexible, high-pressure air hoses are connected to themetal lines from the air compressor. These hoses allowthe technician to take a source of air pressure to thevehicle being repaired. Quick-disconnect couplings areused to connect air hoses and air tools to the compressedair system without using a wrench. To join or separate aquick-disconnect coupling, pull back on the coupling"souter sleeve with finger pressure. With the sleeve pulledback, you can push the coupling together or pull it apart.

Other ComponentsCompressed-Air SystemThe components of a compressed-air system includean air compressor, air lines, air hoses, and air tools. Inaddition, a pressure regulator, filter, and lubricator maybe attached to the system. Air tools are driven by thecompressed-air system. Air-powered tools can be foundin nearly every service facility.

A pressure regulator is used to set a specific pressure in the compressed-air system. This pressure is oftencalled shop pressure. In most cases, shop pressure isbetween 100 and 150 pounds per square inch (psi). Afilter may be connected to the system. The filter removeswater from the compressed air. This increases the life ofair tools. In addition, a lubricator may also be connected

Air ToolsAir tools use the energy of compressed air for operation. They are also called pneumatic tools. Air tools arelabor-saving devices and well worth their cost. Alwayslubricate an air tool before and after use. While pressingthe air tool"s trigger, squirt a few drops of air tool oil intothe tool"s air inlet fitting. Not only will the oil protect theinternal parts of the tool during use, but it will also prevent the internal parts from rusting during storage.

Air RatchetAn air ratchet is a special impact wrench designedfor working in limited space. Look at Figure 4-2B. Forinstance, an air ratchet is commonly used when removingwater pumps. It will fit between the radiator and engineeasily. It works in much the same way as a hand-toolratchet. An air ratchet normally has a 3/8" drive.However, it does not have very much turning power.Final tightening and initial loosening must be done withhand tools.

Impact Sockets and ExtensionsSpecial impact sockets and impact extensions mustbe used with air wrenches. These are case hardened,thicker, and much stronger than conventional sockets andextensions. A conventional socket can be ruined orbroken by the hammering blows of an impact wrench.Impact sockets and extensions are easily identifiedbecause they are flat black, not chrome.Caution!Know when and when not to use power tools.In most situations, power tools will speed upyour work. However, there are many timeswhen they should not be used. For example,never use an impact wrench in place of a torquewrench. An impact wrench will not torque critical fasteners to their correct specification.Problems and comebacks will result.

BlowgunAn air-powered blowgun is commonly used to dryand clean parts washed in solvent. It is also used to blowdust and loose dirt from parts before or during disassembly. See Figure 4-4A.When using a blowgun, wear eye protection. Directthe blast of air away from yourself and others. Do notblow brake and clutch parts clean. The dust from theseparts may contain asbestos. Asbestos is a cancer-causingsubstance. Another type of blowgun is a solvent gun,Figure 4-4B. It can be used to wash parts that will not fitinto a cleaning tank.

Air DrillAn air drill is excellent for many repairs because ofits power output and speed adjustment capabilities. Itspower and rotating speed can be set to match the job athand. Look at Figure 4-5. With the right attachments, airdrills can drill holes, grind, polish, and clean parts.A rotary brush is used in an air or electric drill forrapid cleaning of parts, Figure 4-6. It can quickly removeold gasket material, carbon deposits, and rust with a minimum amount of effort.An abrasive pad is another type of cleaning tool thatcan be used in an air or electric drill. It is used forremoving old gasket material. It has the advantage of notscratching aluminum like a rotary brush can.A rotary file, or stone, can be used in an air drill,electric drill, or air (die) grinder, Figure 4-7. It is handyfor removing metal burrs and nicks. Make sure the stoneis not turned too fast by the air tool. Normally, the maximum speed is printed on the file or stone container.Warning!Use a high-speed rotary brush in an air drill. Abrush designed for an electric drill may flyapart. To be safe, always adjust an air drill tothe slowest acceptable speed when using arotary brush. Also, always wear eye protection.

Electric ToolsThere are many electric tools that can be useful to atechnician. Some of these tools, such as a drill press orgrinder, may be fixed to the floor or a bench. Other tools,such as a drill, are portable and can be taken to the job site.

Figure 4-8. The grinding wheel on a bench grinder is used tosharpen tools. The wire wheel can be used to clean and polishsmall parts. Always keep shields, tool rests, and guards in place.

Transmission JackHydraulic ToolsHydraulic tools are powered by pressurized liquid.The hydraulic tools typically used in the automotive shopinclude jacks, cranes, and presses. These tools are discussed in the next sections.

Shop EquipmentIn addition to pneumatic, hydraulic, and electrictools, there are various pieces of shop equipment that atechnician may find useful. These include tire changers,stands, cleaners, welders, lights, and creepers. These areall discussed in the following sections.

Power cordFigure 4-21. Soldering irons and guns produce enough heat tomelt solder for joining wires and small metal terminals.ASoldering iron. BSoldering gun. (Florida Dept. of Voc. Ed.)

A creeper is useful when working under a car supported on jack stands, Figure 4-25A. It lets the technician easily roll under vehicles without getting dirty. Astool creeper allows the technician to sit while workingon parts that are near the ground. See Figure 4-25B. Forexample, a stool creeper is often used during brakesystem repairs. The brake parts and tools can be placedon the creeper. The service technician can sit and still beat eye level with the brake assembly.

Fender covers are placed over fenders, upper grille,or other body sections to prevent vehicle damage. Theyprotect the paint or finish from nicks, scratches, andgrease. See Figure 4-27. Never lay tools on a painted surface. Costly scratches may result.Seat covers are placed over seats to protect themfrom dirt, oil, and grease that might be on your workclothes. These covers should be used while driving thevehicle or while working in the passenger compartment.

Roll-Around CartA large roll-around cart or table is handy for taking anumber of tools to the job. One is pictured in Figure 4-26.A technician can quickly place all needed tools in the cartand take them to the vehicle. The cart places the toolswithin hand"s reach. This saves time and effort before,during, and after the job.

Figure 4-25. AA creeper is for working under a vehicle.BThe stool creeper is commonly used during brake and suspension repairs. You can sit on the stool and store tools on thebottom. (Snap-on Tool Corp.)

Power tools use electricity, compressed air, orhydraulic pressure (liquid confined under pressure). Large shop tools, such as floor jacks, partscleaning tanks, and steam cleaners, are classifiedas shop equipment.

The most common source of power for these tools is an electric motor base, but there are some which are fueled by gasoline, however; this source of power is rare and generally applies to garden tools.

An electric power tool is a common item of almost everyone’s everyday life. These incredibly useful tools are found in nearly every industry, and help to perform tasks that could otherwise be impossible or extremely difficult to complete.

Power tools are used literally everywhere, in the home, apartment, condo and all the way to the professionals at job sites and builders. Many types of power tools will also be found in use with metalworkers, DYI hobbyists, mechanics, and so on.

A cordless drill (or power drill) is an electric drill with rechargeable batteries and it is the most common item in any garage, construction site, or workshop.

This is one of the first power tools that everyone should have. These drills have enough strength to drive screws and drill into thick planks of wood.The cordless drill is the perfect representative tool for those who enjoy performing projects around the home.

There are also corded drills and these machines are leaner, lighter, and bit more powerful than the cordless version. They are also noisier, not as convenient to use, and restrict your mobility.

A cordless drill is irreplaceably more convenient even though they may be a bit bulkier, and a heavier tool. The biggest benefit of the cordless drill is not having to be hindered or limited by the power cord.

You can tell how powerful a cordless drill is by looking at its voltage. More voltage will give you more power. There are high voltage models, light-duty models, and then the medium general-purpose models.

Torque is another feature to check when choosing your cordless drill. If you plan on drilling on harder surfaces, you will want more twisting force. Torque is what allows the drill to apply more of the twisting power to your work surface.

This tool uses a collet which accepts bits and hex-shanked drivers A good impact driver is going to be a versatile and powerful tool to add to your collection of necessary tools.

When choosing the impact tool for your needs, you will want to check the power, torque, speed and hammer action, so the tool handles the jobs you need to finish.

This tool is not used for driving screws, and should never be used in this manner. While the hammer drill is often confused with the impact driver, you should know these are two entirely different power tools.

In the line of construction power tools, the rotary hammer is one that will perform your heavy-duty jobs such as chiseling and drilling into hard materials. It is much like the hammer drill as it also pounds its drill bit in and out as it spins.

Rotary hammers use a piston mechanism rather than a special clutch, which allows it to deliver a more powerful hammer blow and drill a much larger hole faster.

These tools have two pistons – a flying piston and a drive piston. Its electric motor turns a crank that then moves the drive piston back and forth in the cylinder.

The rotary action of the rotary hammer can be turned off and on so just its percussive force can be used. Point and chisel accessories are often with this power tool, so you can also use it as a small chilling tool.

Impact wrenches use compressed air as its power source, although there are also hydraulic and electric-powered models as well as cordless ones becoming more popular.

The chuck is what holds your electric screwdriver together. These are pretty simple parts, and the switch is what sends the power to the motor.Electric screwdrivers give you an advantage if you are working in electronics, as they pack power precision with an on and off switch that is convenient to use.

Light assembly applications such as those done with electronics, or medical devices that use intricate work are perfect applications for an electric screwdriver. For more heavy applications like driving screws in hard materials, a power drill is used.

The rotary tool can also hold a small sharpening wheel that works great for sharpening knives, shears, scissors, and more. When you set the speed to high, make sure you turn the tools away from you, as it will create sparks as it sharpens.

The dictionary describes a jigsaw as a portable power saw that incorporates a reciprocating blade. This saw can be used in a variety of tasks depending on the kind of cut you need.

The jigsaw is also a fine-toothed power tool that has a narrow blade and will cut out curved outlines for you.A jigsaw is considered a grandmaster at cutting shapes in a range of materials, including drywall. It is also able to make bevel and compound cuts in boards and other materials.

There are a variety of designs and they vary according to the saws speed, and power. The designs also differ from the less powerful portable version to the handheld models that resemble the cordless drill, all the way to the corded models designed for the demolition work or construction site jobs.

The power tool known as the circular saw uses an abrasive or toothed disc or blade to make different cuts in material with a rotary motion that spins around an arbor.

The circular saw is commonly powered by electricity, but some models are powered by an engine or hydraulic motor to allow it to be fastened to heavy equipment so the need for separate energy sources is eliminated.

Standard or power miter saw — This miter saw is a powered version and will make straight crosscuts on your project using a wide range of angles. These saws commonly make forty-five-degree straight cuts used for framing documents, pictures, or other prized and important pieces.

A band saw is a fixed power tool that has a sharp, long blade that has a continuous band of toothed metal that is stretched between two or more wheels and cuts materials.

Most of the band saws you will see have two wheels that rotate in the same plane. One of the wheels is typically powered, however, some have three and sometimes four that will distribute the load.

Contractor model table saws — are heavier and much larger table saws. These models are attached to a base or stand, and often have wheels attached to the base for ease in moving were needed to be used. These models are also used by homeowners and hobbyists as they have a standard electrical circuit that gives adequate power to operate them.

Some models of this power tool allow you to cut angles other than at ninety-degrees, which will greatly speed up your assembly of projects such as making cabinets.

An angle grinder is sometimes called a disc grinder or side grinder and is a portable hand power tool. It is used to grind and polish, and although designed as a tool for rigid abrasive discs, it has an interchangeable source of power that allows for a wide variety of attachments and cutters.

When choosing an angle grinder, you want to make sure it has the right disc size and has a powerful motor. You will also want to check the power source, RPMs, and arbor size.

The shop vac has a much more powerful motor than the house-cleaning vacuum models, and they often need to be flipped and lifted in order for you to empty the dirt from them. Another major difference is the filter system. Household vacuums have good filters to improve air quality, and the shop vac does not have a filter system.

Some of these power tools are as large as 0.7 by 1.2 (2 ft. 4 in by 3 ft 11 in). There is often a significant amount of sawdust created with the use of belt sander. For this reason, most of these tools are equipped with a form of the dust collection system. Some of the dust collection systems are as simple as a cloth filter bag.

The random orbital sander uses from an eighty grit to a one-hundred-sixty grit range. They are a delicate tool when compared to some of the power sanders on the market, however, compared to the palm sander, they are almost brutish and significantly larger.

The random orbital sander can typically be held and operated with one hand, however, there are a few models that are more powerful and will require the use of both hands.

The blade protrudes beyond the base plate. As a power tool, a wood router has an electric motor. The hand-held versions today are most often called a router plane, and this power tool is considered one of the most versatile woodworking power tools on the market.

Some of the models have a soft-start feature so their speed can be built up slowly. This is a desirable feature for the routers with a large cutter. They can hold a three-horse power router and be able to turn it on without the soft-start would be dangerous.

Wood routers have numerous uses, and with the multitude of bits and jigs with this power tool, makes them capable of creating mortises, tenons, dovetails, moldings of infinite varieties, cutting circles, making raised panel doors and frames, and much more.

These construction power tools are typically operated by compressed air, electromagnetism, propane, butane, or for the powder-actuated tool variety, a small explosive charge.

These air tools are used in building or construction work and include tools such as jackhammers, power hammers, air impact wrenches, air sanders, and grinders to just name a few.

An air compressor is able to pump high-pressure air into gas cylinders to supply divers and help power pneumatic tools. Air compressors are also useful for homeowners and there are special air compressors that are used for inflating tires.

Air compressors are typically powered by electricity or gas. These machines are used in manufacturing plants, gas stations, construction sites around the country, as well as in many residential garages.

They have become increasingly popular in home workshops, garages and basements. The air compressor can be used to operate a number of power tools, including spray guns, wrenches, nail guns and many more.

Most of these machines have a crankshaft that connects pistons or rods, a cylinder, and a valve head. The air is driven out of the tank, and to the power tool.

If you use an air-nailer, the air compressor is ideal for powering them. These machines also make it easy to complete spray-painting jobs, and if you are considering a paint job for kitchen cabinets, this is exactly what you looking for to achieve smooth, well-done painting.

This list of twenty-five power tools shows you the incredible amount of work that can be accomplished with these machines that will save you a lot of time and physical labor.

Power tools have multiply users and use both in the home and industrial establishments. Two of the top advantages of using these handy machines are they get your work done at a reasonable speed and they are more effective than other tools.
