• Once the minimum temperature has been achieved it is recommended to slowly introduce load to the
output of the drive unit, which in turn will increase the internal gear oil temperature.
Note: The host machines cooling system and the lubrication system for the engine do not lose heat immediately
upon shutdown. The transmission and the hydraulic system lose heat more rapidly because of more exposed
areas. The Planetary gearbox & motor cases cool rapidly, since the cases do not operate as warm as other
compartments. Therefore, after any period of down time on the machine, ensure you achieve full operating
temperatures through following start up instructions. Thick oil can also cause high case pressures which in turn
cause shaft seal problems.
Operating Procedure - AUGERING
• This unit is designed for drilling vertical or horizontal holes 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.
• With the auger raised o the ground and the host machine’s engine set at a low RPM, activate the host
machine’s 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.
• 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 host machine's engine RPM. To decrease auger RPM, decrease host
machine’s engine RPM.
• 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.
11 Operating Instructions
Your Digga Planetary drive is specically designed for drilling and rotational operation only, it is not a lifting device!
