7.2.1.3 Operating the auger
The auger drive unit is started by turning the auxiliary hydraulics control lever of the auger to its locking
position. Start the auger at a safe area to see the rotating direction; make sure that the auger rotates
clockwise. Set the engine rotating speed according to operating conditions. Operating at full rotating speed
may be possible, but generally modest speed will give the best results.
DANGER
Risk of entanglement - Never leave the equipment running unattended. Start the
auger only when beginning to use it. Do not go near the equipment when another person
operates the controls of the loader. Always follow the safe stopping procedure before
going near the auger.
Remember to unlock the angle adjustment of the Drive unit before using the auger. Also,
make sure that the quick coupling plate or the frame of the Drive unit are not in contact
with the Drive unit, so that the hinge will allow the auger to move
To operate the auger:
Position the auger against the ground in upright position. Gradually lower
the boom to apply force on the auger. The needed force to push the
auger down depends on the operating conditions and type of soil. Also,
the bigger the auger, the more time should be allowed for the auger to lift
soil before operating the loader controls.
Do not push down too hard, so that the front wheels of the loader remain
in contact with the ground to avoid stalling the auger and to avoid
applying excessive load on the auger and the drive unit.
Note that in addition to controlling the loader boom, the position of the
auger must also be corrected by using the drive pedals or the telescopic
boom of the loader.
Lift the auger out of the ground regularly to clear material from the auger
and to maintain drilling effectiveness. Smaller augers may need manual
cleaning especially when working on moist soil. Frequent clearing of the
hole will also make it easier to pull the auger out from the hole. Keep the
auger rotating the same direction when pulling out, so that material will
also be pulled.
Do not try to clean the auger by swinging it with force or by hitting it, it
may bend or its teeth may get damaged from impact.
Augers can’t pull or break large stones from the ground. The augers are
not intended for other purposes than making holes on various types of
soil. If penetration speed decreases clearly, lift the auger from the hole
and check for stones.
Adjust the drilling position during use of the auger. Keep the auger aligned with the
intended direction of drilling, so that the auger will pull itself efficiently into the ground. If
the position is not corrected during drilling, the auger can get damaged because of
bending of the auger.
