81OTHER ADJUSTMENTS AND REPLACEMENTS
CHANGING THE BUCKET
To avoid personal injury:
A There are two people required to replace the
bucket. One person operates the excavator,
and the other one mounts the bucket.
The person who mounts the bucket must
command-guide the movements of the front
end attachments. The operator should move
the front end attachments only according to the
commands of the person who mounts the
bucket. Continuous visibility between both
persons is indispensable. If there is no
visibility, stop working immediately.
A When replacing the bucket, make sure to wear
eye protection, a helmet and protective gloves.
A During attaching and detaching, chippings and
burns may occur at the bolts or bushings.
These may cause severe injuries.
A Never use your fingers for the alignment of the
components (linkage, bucket, arm). The
components may sever your fingers by
uncontrolled movements.
A Read the manual of the attachment to do a
correct operation safely when other
attachments are installed instead of Kubota
specified bucket.

To avoid personal injury:
A When changing fuse, stop the engine and turn
the key in position "STOP". Keep the lock lever
for attachment control in the "LOCK" position.
BReplacing Fuses

2. Replace the burnt out fuse with a fuse having the same
capacity.
