1. Only operate this unit after thoroughly reading and understanding this Operator's Manual.
2. Inspect the Auger teeth and points for wear or breakage. Replace as necessary. It is advisable to keep spare
points and teeth on hand.

Increase or decrease the skid loader engine RPMs accordingly.

ground and penetrates about 2 inches.

8. Activate the auger control valve so that the auger is tuning in a clockwise rotation. Only use enough down
force to start the point to dig.
● Warning: Do not apply excessive pressure or the auger may stall. If this happens, release some
pressure from the auger.
9. Once the auger digs approximately 24", raise the auger high enough to clean out the hole. Repeat until the
desired depth is achieved.
10. Under certain conditions, the auger may become stuck. In this situation, do not attempt to raise the auger!
Stop, reverse the auger rotation by moving the control valve lever to the reverse position and slowly raise
the auger. Once the auger is free, return the control valve lever back to the forward position and commence
digging.
11. When the desired depth is achieved, all the auger to continue to turn a few seconds longer to clean out the
hole.
