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 helper before starting the tool.

4. Steady the tool and position the auger bit 90° to the ground.

5. Stand with your feet shoulder width apart.
   Note: Hold the tool correctly and be ready to counteract normal or sudden movements. Have both hands available. High reaction torque can develop if the tool stalls, which can be caused by excessive loads being applied to the drill bit, by the drill snagging on the material being drilled into, or by the drill bit breaking through the material being drilled.

Tool Activation – Detail E

1. Ensure the auger bit is 90° to the ground.

2. Raise the auger bit above the ground.
   Note: Never operate the tool if you cannot be sure that underground utilities are not present, such as electrical cables, gas pipes, etc. These can cause a hazard if damaged with the tool.

3. Fully squeeze the trigger.
   Note: Always fully squeeze the trigger during operation. Operating the tool with a slightly depressed trigger increases the hydraulic pressure and can result in unexpected kickback.

4. Slowly lower the auger bit to the ground.

5. After reaching the desired depth, release the trigger.
   Note: If you encounter a breakdown or the tool stops for any reason, release the trigger and power down the hydraulic power source.

6. Squeeze the reverse trigger to reverse the auger bit.

7. Lift the auger straight out of the hole and release the trigger. Ensure the auger bit has stopped before the tip of the bit reaches the surface.

Tool Use Tips

• On soft ground, EA08 will penetrate the ground easily and may require you to apply a slight lift to the tool handles.
• On hard ground, you may need to apply slight down pressure on the tool handles.
• During operation, frequently lift the auger to clear dirt and debris from the hole.
