Tool Setup
Do not install or change tool accessories while the
hydraulic power source is connected. Accidental
engagement of the tool can cause serious injury.
Disconnect the hydraulic power source before installing
or changing accessories.
1. Disconnect the tool from the hydraulic power source.
Install Handles and Torque Tube - Detail B
2. Insert one handle onto each of the handle mounting ears.
Note: The trigger handle comes installed from the factory.
3. Thread one cap screw into each handle and torque to 40 Ft. Lbs. (54
Nm).
4. Insert the torque tube pivot into the mounting ear that is angled 45°.
5. Insert the torque tube locking pin. Ensure the locking pin is pushed
through both sides of the mounting ear and is locked in place.
Note: The torque tube reduces reaction forces on the operator. You must use
the torque tube at all times when operating the tool.
Install Bit - Detail C
Never operate the tool unless the inserted bit is
retained. Bit can become a high velocity projectile.
Secure the bit as shown in this manual.
1. Insert the auger bit onto the drive hex.
2. Fit the tool retainer pin through the bit and drive hex.
3. Insert the cotter pin through the end of the tool retainer pin. Ensure it is
secure and the bit is locked in place.
Note: Loose fitting bits and adapters can increase vibration. Use as few
adapters as possible and ensure they fit tightly.
Tool Operation
Connect to a Hydraulic Power Source
1. Using a calibrated flow and pressure gauge, check the output of the
hydraulic power source. Ensure it matches the flow and pressure in
“Specifications” on page 8. Hydraulic fluid must be 50°F or above.
Preheat if necessary.
2. Ensure that the hydraulic power source is equipped with a relief valve
set to open at the maximum relief pressure. See “Specifications” on
page 8.
3. Wipe hose couplers with a clean, lint free cloth.
4. Connect the return hose to the male coupler.
5. Connect the pressure hose to the female coupler.
6. Ensure couplers are undamaged, properly connected and are tight.
7. Power up the hydraulic power source.
Holding the Tool - Detail D
Operators must use the torque tube. Ensure torque
tube is installed and properly anchored. Serious injury
could result from losing control of the tool.
1. Anchor the torque tube to a trailer hitch, ground stake or other solid,
heavy object.
2. If operating with a helper, the helper will grab the handles opposite of
the trigger.
3. The operator will grab the trigger handles.
Note: The operator at holding the trigger handle must asses the risk to the
