INTENDED USE
This unit is designed for drilling vertical holes, core barreling or rotating piers into the ground. Use in any other way is considered
contrary to the intended use.
After all installation instructions have been completed, safety information read and understood, and the rest of this operator’s manual
has been reviewed, your DIGGA Auger Drive is now ready for use.
1. With the auger raised off the ground and the vehicle engine set at a low RPM, activate the host machines drive control valve to
determine which position the control valve lever must be in to turn auger in a forward (clockwise) rotation. This is the “digging”
position.
2. Before beginning to dig, experiment with auger speed to determine a suitable auger RPM. Generally in light and sandy soil a high
RPM is desirable. In hard, rocky, or frozen soils a slower RPM is desirable. To increase auger RPM, increase vehicle engine RPM.
To decrease auger RPM, decrease vehicle engine RPM.
3. Raise the Auger Drive so the auger hangs vertical and the drive is clear of the cradle, then lower the auger into the starting position.
4. Ensure the crowd on your machine is forward and not back. This will keep the Drive clear of the cradle and allow the auger to move
freely from side to side and forward and back. The pendulum action must not be hindered otherwise damage / bending of the shaft
or auger may occur. Lower the auger into the ground ensuring the auger drive does not stall and remains in a vertical position, start
rotation of the auger.
5. As the auger starts to load up with spoil, stop the rotation whilst still in the hole and raise the auger vertically. Move away from the
hole, rotate the auger & stop, rotate the auger & stop in the forward direction to remove the spoil. DO NOT rapidly engage forward/
reverse action to remove spoil.
YOUR DIGGA HIGH PERFORMANCE PLANETARY DRIVE IS SPECIFICALLY DESIGNED FOR DRILLING
AND ROTATIONAL OPERATION ONLY, IT IS NOT A LIFTING DEVICE !
