REMARK
•
Lubricate with grease thoroughly until the grease
comes out from the end faces.
•
When replacing the bucket, replace the dust seal with
a new one if it is damaged. If a damaged one is used
without being replaced, sand and dirt may enter the
part of pin and cause abnormal wear of the pin.
METHOD FOR INVERTING BUCKET
Invert the bucket according to the following procedure.
1.
Lower the bucket to the flat ground.
REMARK
When removing the pins, place the bucket so that it is in light contact with the ground.
If the bucket is lowered strongly to the ground, the resistance will be increased and it will be difficult to re-
move the pins.

After removing the pins, make sure that mud or sand does not get on them. Dust seals are fitted at both
ends of the bushings, be careful not to damage them.
