OPERATION INSTRUCTIONS

To install pipes,

1. Swing the cutter, reamer and die head out of the way so that you can access the chuck.
2. Insert the pipe into the chuck so that the end to beworked or the cutting mark is located about 12 inches to the front of the chuck jaws. If the pipe is being cut to length, mark at the desired length.
3. Insert workpieces less than 2 feet long through the frontof the machine. Insert longer pipes through either end so that the longer section extends out past the rear of the machine.
4. Tighten the rear centering device around the pipe by using a counterclockwise rotation of the handwheel at the rear of the machine. This prevents movement of the pipe that can result in poor thread quality.
5. Secure the pipe by using repeated and forceful counterclockwise spins of the chuck handwheel at the front of the machine. This action “hammers” the jaws tightly around the pipe

To replace dies if they are worn or damaged,

1. With machine unplugged, remove die head by removing carriage rail set screw. Lay die head on bench with numbers facing up.
2. Loosen clamp lever. Move size bar all the way in direction of the “REMOVE DIES” marker and turn throwout lever to “OPEN”. The die head cams should now be released from the dies.
3. Pull the old dies out of the die head assembly (if they feel stuck, try pulling on the throwout lever, the cams may still be biting a little). Note that dies feature a line mark and a number, 1 through 4. Place the new dies into the corresponding die slotsso that the numbers match. Insert them up to the length marked by the line mark, then turn the throwout lever to the “CLOSE” to capture the dies. Place die head back in the machine.
4. Adust die head size bar until the index line on lock screw or linkis aligned with proper size mark on size bar. For bolt threads, align index line with BOLT line on size bar, then tighten clamp lever to secure.
5. If oversize or undersize threads are required, set the index line in direction of OVER or UNDER size mark on size bar.

To cut pipe threads,

1. Check that the dies are the proper type and are not worn or chipped.
2. Lower the die head into position. Make sure the cutter and reamer are swung out of the way.
3. Adjust die head to the proper size.
4. Turn the thArowout lever to the “CLOSED” position.
5. Turn the power switch “ON”. Cutting oil should start circulating and the pipe should start turning.
6. Use carriage handwheel to engage dies with pipe and begin cut. When cut is finished, the end of the pipe should hit the trigger and force the throwout lever open. Move die assembly back using carriage handwheel and swing die head up to access the pipe threads.

To cut pipe,

1. Make sure the die head and reamer are swung out of the way.
2. Hold the pipe cutter just above the pipe and use carriage handwheel to line up cutter wheel with mark on pipe, then rest the cutter on the pipe.
3. Tighten cutter feedscrew handle while keeping the cutter wheel aligned with the mark.
4. Turn the power switch “ON”. Cutting oil should start circulating and the pipe should start turning.
5. Holding the cutter feedscrew handle with both hands, tighten slowly and continuously until the pipe is cut. Do not force the cutter into the workpiece.
6. When cut is finished, swing cutter up to access the cut pipe.

To ream pipe,

1. Make sure the cutter and die head are swung out of the way.
2. Lower reamer arm down into position.
3. Move reamer forward by opening reamer lock latch and sliding reamer toward pipe until latch reengages.
4. Turn the power switch “ON”. Cutting oil should start circulating and the pipe should start turning.
5. Move reamer into pipe and begin reaming by turning carriage handwheel.
6. When reaming is complete, move carriage lever back. Open reamer lock latch and retract reamer until latch reengages, then return reamer to the UP position.

To remove pipe,

1. Turn the power switch “OFF”.
2. Use repeated and forceful clockwise spins of the speed chuck handwheel at the front of the Power Drive to release the workpiece from the speed chuck jaws.
3. If necessary, loosen the rear centering device using a clockwise rotation of the handwheel at the rear of the Power Drive.
4. Slide the workpiece out of the Power Drive, keeping a firm grip on the workpiece as it clears the Power Drive. To avoid injury from falling parts or equipment tip-overs when handling long workpieces, make sure that the end farthest from the Power Drive is supported prior to removal.
5. Clean up any oil spills or chips on the ground surrounding the device.

MAINTENANCE INSTRUCTIONS

Jaw inserts

• Clean jaw inserts daily with a wire brush.

• If jaw inserts fail to hold pipe or rod or are otherwise worn or damages, replace them
  NOTE , even if only one jaw insert is damaged, replace the entire set to ensure workpiece will be properly held throughout cutting procedures.

• To replace jaw inserts, place a screwdriver in the insert slot and turn 90 degrees in either direction, then place insert sideways on locking pin and press down as far as possible

• Hold insert down firmly with screwdriver. Turn until teeth face up.

Lubrication

• Use cup grease to lubricate shaft bearings every 2 to 6 months depending on use. Grease fittings are located at both ends of each carriage shaft.

Motor

• Check motor brushes every 6 months. Replace when worn to less than 1/2″.
• If commutator is worn, the outer dimension of the commutator should be turned and the mica should be undercut before replacing brushes. This should only be done by qualified repair personnel.
• If motor is otherwise damaged, replace motor. To remove the motor, unplug the motor receptacle from the switch box, remove the 2 screws holding the motor, and loosen the screw in the power drive body at the neck of the motor.
