89MAINTENANCE OF THE BACKHOE
LUBRICATION
Lubricate all grease fittings every 10 hours of operation.
High quality grease designated "extreme pressure" and
containing Molybdenum disulfide is recommended. This
grease may specify "Moly Ep" on its label.
BUCKET SERVICE
To avoid personal injury:
A When servicing or repairing pins in cylinder
ends, bucket, etc., always use a brass drift and
hammer. Failure to do so could result in injury
from flying metal fragments.
BChanging the Backhoe Bucket
Changing the backhoe bucket becomes necessary as the
type of job to be accomplished changes. In most backhoe
operations, this is a common occurrence.
By using the following instructions, this job will be quick
and easy. Always select a smooth level area to change
buckets.
Place the bucket to be installed on its bottom, near the
backhoe dipperstick and the bucket to be removed.
Position the bucket to be removed, hydraulically, into this
"NATURAL" position, just touching the ground.
BChanging the Bucket Teeth
The bucket teeth are locked with bolts on the bucket. Even
though the teeth are heat-treated and hard, they will
eventually need replacement. As the teeth become worn,
the resistance of digging will increase. When the teeth are
worn, install new teeth using new bolts.
Bucket teeth may be removed and stored when drainage
work is required. This type of work may not require
trenching teeth.
