3 Ⅰ. SUMMARY Model XQ114/6YB(4 1/2") hydraulic power tong is an open type power tong for the making up and breaking out of tubing in well services. This product has the following features: 1,The tong is made up of master tong and backup tong, the master tong has a high and low gear train, the tong is compact, light and efficient. 2, The master tong and backup hydraulics operate on valve banks independent of each other. 3,The tong has incorporated a new system of disc brake to hold the jaws to connection more effectively. 4,Makeup and breakout are made easy with a simple turn to the reset knob on the tong and backup. 5,The backup has been supplied with quick coupling hoses and connections for quick and easy installation for jobs where you need a backup and the backup can be removed in seconds for jobs that a backup is not required. Ⅱ. SEPCIFICATION 1, Application:Tubing:73mm-114mm (2 7/8"to 4 1/2") 2, High gear rated torque:1.5 kn.m (1106 ft.lbs) 3, Low gear rated torque:6 kn.m (4425 ft.lbs) 4, high gear max rotation speed:85 RPM 5, Low gear max rotation speed:20 RPM 6, Opening of tong head:118 mm 7, Overall dimension (L W H): mm 8, Weight:220 kg(485lbs) 9, Rated system pressure:1595 Psi 10, Max oil supply:100 L/ min Ⅲ. INSTALLATION A, Hanging: Connect lift with tong hanging rod and hang the tong on the derrick of workover rig, the hanging point is 15 m above ground and the hanging should be in free condition. The distance between the tong center and the center of the well is recommended to be 0.5m. The hanging height is proper when the backup tong could rightly grip the tubing collar. B, Level: Adjust the screw (Z6-58)on the tong hanger to level the tong and backup, this should be done to ensure proper gripping of the jaws. C, Back guy: Tie one end of back guy on derrick and the other end on back guide seat of power tong, back guy should be capable of bearing a load of 20 KN, when power tong is in make up position, the back guy should be at right angle to the tong and on the opposite side of operator who operates the control handles, this insures a safe operation. D, Pressure hoses: Connect hoses from the hydraulic power source to the control valve bank of the power tong. The inlet and the outlet hoses can t be misconnected. 1

4 Ⅳ. OPERATION Making up tubing can be spun first in high gear range, final torques must be done in the low gear range. A PSI chart is provided to convert PSI to FT.LBS torque. Break out must be started in low gear range, once the joint has been loosened, the final brake out can be done in the high gear range. 1, Make-up: After aligning the opening tong head with the backup, turn the reset knobs of each (Z6-49) and (B6-3) switch the arrow to point the direction of make-up. Locate the tong and backup on to the tubing. The backup should be engaged to lock onto the tubing first. Once the backup jaws have been locked on, commence make up with the tong. After the tubing is made up, reserve rotation of the tong to align the opening of the tong with the tubing. Once this is accomplished, reverse the backup to align the opening of the backup to the tubing. The tong can be moved off the tubing. Confirm proper make up torques required from your tubing supplier. 2. Break out Aligning the opening tong head with the backup, turn the reset knobs of each(z6-49) and (B6-3) and switch them to point the direction of break out, then push it towards the tubing. Making the jaws of the tong and the backup line up squarely on tubing. Engage the backup first locking onto the tubing. Commence break out with the tong. Initial break out should always be done in low gear range. Once break out is accomplished. The joint may be spun off in high gear. To come off the couplings reverse the rotation of the tong and backup slowly to align the opening of the tong and backup to the tubing. The tong can now be removed off the tubing. 3. Replacing jaws. Tong and backup insert jaws slide into the tong heads easily. When you dismount jaws, turn tong head firstly, make the stop screw on the jaw set bracket expose from the opening tong head, loose the stop screw, then you can take out the jaws from the center of tong head. Mounting operation procedure is just on the contrary. Ⅴ. MAINTENANCE & LUBRICATION It is suggested that a regular maintenance program be established, to assure dependable operation of the tubing tong. The following recommendations concerning cleaning, lubrication, and cleaning will enhance the life expectancy of the tong and assure safety to operating personnel. A, Cleaning The tong should be thoroughly cleaned with a good petroleum base cleaning agent, after each job, prior to storage, it is recommended that periodically the motor and valve assembly be removed, along with the top tong plate, so that guides, rollers and gears can be properly cleaned. B, lubrication A good grade of multipurpose bearing lubricant which is compatible with expected ambient temperature is recommended along with the following lubrication procedures, at the completion of each job prior to storage. 1, All grease fittings should have 2 to 5 shots of grease after each job. 2, Rotary gear cam surface should be well greased applying with a rag or a brush. 3, Cage plates/rings should be coated with grease both through the grease nipples and coated on the rings. 4, Gears can be greased by removed the side inspection cover plate and apply grease directly to the gear teeth. 2
