OPERATING TECHNIQUES CONTINUED
1. Shift transmission to low, forward and open bucket.
2. To make maximum penetrations into material to be moved, open bucket until it is parallel with ground and lower
it to ground level. In this position, bucket cutting edge will meet with least amount of resistance.
It is necessary to operate the bucket control lever intermittently because the bucket
hydraulic circuit overrides the boom circuit.
Whenever the bucket circuit is in operation, hydraulic pressure in the boom circuit is cut
3. Once bucket enters material, pull boom control lever up to RAISE and start closing bucket. Operate bucket
control lever intermittently to ROLL BACK so boom will raise at a nearly constant rate. Should bucket penetrate
so deep that boom cannot raise properly, back away slightly.
4. Digging in hard material can be aided by "wiggling" bucket edge immediately after penetration. Operate bucket
control lever alternately between its ROLL BACK and DUMP positions. This action will loosen material and
improve bucket loading. Coordinated operation of two hydraulic control levers as bucket enters material will
yield satisfactory bucket loads.
The boom assembly need not be fully raised to load the bucket. Maximum bucket loading
will be obtained before the bucket reaches operator eye level.
5. Shift boom control lever to HOLD once bucket has been filled. Back loader away from loading site and lower
bucket to within two feet of ground level. Carry bucket near ground to provide better transporting stability.
Transport loads close to the ground. If it is necessary to carry the bucket raised in transit, the operator should use
increased caution. Perform all steering and shifting as smoothly as possible.
The speed used to transport loads should be relative to the bucket carry position and the type of route used. Safety
should be considered at all times. Carry the bucket low and closed. Travel slowly anytime a load is carried over
rough and/or sloping footing. A loaded bucket should never be transported with the boom fully raised.
Use the lower transmission speed range for bucket loading and the transportation of loads. The higher speed
range may be used for making return trips to the loading sites. Carry the bucket low at high road speeds.
