Contents Table of Warranty Specification Ordering Sheet Instructions Installation HAWKJAWOPERATION, MAINTENANCE AND

The HawkJaw 65K-950JR is a hanging unit that will spin, make up and break out drill pipe. Itis revolutionary because the tool spins and makes up drill pipe or breaks out and spins drill pipein 12 seconds or less. A patented self-energized grip system provides consistent torque values tothe drill string. Consistent torque ensures that wash outs and "post tightening" down hole do notoccur under normal conditions.

A patented adjustable wrench system eliminates the need for separate jaws, spinning wrench roll-ers or gripping dies. The HawkJaw"s modular design enables the unit to be maintained on the rigfloor.

The HawkJaw 65K-950JR provides a fast, safe and efficient method of spinning and make up orbreak out and spinning. It eliminates costly and dangerous spinning chain and rig tong accidents.

The HawkJaw improves trip time over any comparable torquing and spinning device in the in-dustry. The unit easily adapts to any land or offshore rig because it hangs in the derrick. Han-dles mounted near the control buttons enable one rig hand to move the hanging unit on and offthe pipe.

Your Hawkjaw must be free of material and workmanship defects for a period of six months fromthe date of delivery. If any items fail because of a manufacturing defect within that period of time,that item will be replaced by Hawk Industries. Hawk Industries at its discretion may extend thiswarranty period.

Factory specifications for hydraulics, pneumatics, lubricants, adjustments and safety precautionsas set forth in the operation and maintenance manual are for the mutual protection of the owner ofthe HawkJaw 65K-2GJR and the company. Failure to adhere to these specifications can reduce theefficiency or life of the equipment and/or cause bodily injury.

WarningThe Hawkjaw includes specially modified valves, fasteners and other components for extremeenvironments and service. Any attempt to substitute standard components could reduce reliabil-ity and performance, void the warranty and/or cause bodily injury. Any modification made byany third party without express written consent of Hawk Industries Inc. shall nullify the existingstanding warranty.

Hanging Cable Location1. Anchor the hanging cable to a point as close to the derrick crown as possible. The longer the hanging cable, the easier the HawkJaw is to move on and off the drill pipe.2. Locate the cable hang point as high above the center of the rotary table as possible. The cable must hang within 2"-4" ft. of the rotary table center.

The hanging cable must permit the HawkJaw to move from the drill pipe connection to themouse hole connection to the HawkJaw rest position (3"- 5" away from the rotary table).

Installation1. Place the HawkJaw on the side of the rotary table away from the setback zone. This allows the drill pipe stands to swing straight from pick-up to stabbing.2. If possible, place the HawkJaw on the opposite side of the setback zone. If the rig has dual setback zones, Step 1 applies.3. The HawkJaw may rest on the rig floor 3" -5" ft. away from the rotary table.

Installation 9 Hanging Cable Requirements1. 5/8" diameter steel cable.2. Appropriate hanging cable hardware for 5/8" diameter steel cable.3. Enough cable length to suspend the Hanger Eye (HE) 20" ft. above the rig floor.4. Enough cable length to allow the HawkJaw to rest on the rig floor 3"- 5" ft. away from the rotary table with the lift cylinder completely stroked out. The lift cylinder is 13" ft. long when completely stroked out.

10 Installation Hydraulic Requirements1. Pressure compensated pump set to pressure compensate at 2600 psi.2. Minimum volume of 20 gpm. 35 gpm for top performance.3. 1" minimum Pressure line. 1 1/4" Pressure line if the power unit is located more than 100" apart from the HawkJaw. The hose working pressure must be 3000 psi or greater.4. 1 1/4" minimum Tank line. 500 psi minimum hose working pressure.5. Hawk approved pressure side non-collapsible on-board 3000 psi filter (HF) (Part # 061- H25). Initial filter element supplied with the HawkJaw.6. Hawk approved quick disconnects (Part # 061-H26). Initial quick disconnects supplied with the HawkJaw.7. Hydraulic power unit located in a clean, dry, ventilated area.8. Enough slack in the lines for the HawkJaw to move from its rest position to the drill pipe connection to the mouse hole connection.
