331/331E/334 Excavator
OPERATING PROCEDURE (Cont’d)
Boom Offset (Cont’d)
The boom offset allows the operator to dig close to
buildings and other structures [A].
Backfilling
Use the blade to backfill the trench or hole after excavating
[B].
Driving The Excavator
When operating on uneven ground, operate as slow as
possible and avoid sudden changes in direction.
Avoid traveling over objects such as rocks, trees, stumps,
etc.
When working on wet or soft ground, put planks on the
ground to provide a solid base to travel on and prevent the
excavator from getting stuck.
If one or both tracks have become stuck in soft or wet
ground, raise one track at a time by turning the
upperstructure and pushing the bucket against the ground
[C].
Put planks under the tracks and drive the excavator to dry
ground.
The bucket may also be used to pull the excavator. Raise
the blade, extend the arm and lower the boom. Operate the
boom and arm in a digging manner [D].
