OPERATION
MACHINE OPERATIONS AND CONTROLS
BUCKET REPLACEMENT
WARNING
When pins are knocked in with a hammer, pieces of metal may fly and cause serious injury.
When carrying out this operation, always wear goggles, hard hat, gloves, and other protective equipment.
When the bucket is removed, place it in a stable condition.
If pins are hit with a strong force, there is a hazard that the pin may fly out and injure people in the surrounding area. Make sure
that there is no one in the surrounding area before starting the operation.
When removing the pins, do not stand behind the bucket. In addition, be extremely careful not to put your foot under the bucket
while standing at the side for the work.
When removing or inserting pins, be extremely careful not to get your fingers caught.
Never insert your fingers into the pin holes when aligning the holes.
NOTICE
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.
Stop the machine on a firm and flat surface and do the work. When
performing joint work, appoint a lead and follow that person's
instructions and signals.
1. Place the bucket in contact with a flat surface, then pull out pins
(A) and (B).
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 remove the pins.
When removing the pin, check the number of shims used to
adjust the play. This is necessary when assembling again.
2. Align the arm with holes (1) and the link with holes (2), then
coat with grease and install pins (A) and (B).
REMARK
When installing the bucket, the O-rings are easily damaged, so
fit the O-rings on the boss of the arm end as shown in the
diagram.
When knocking the pin, move the O-ring down to the regular
groove.
Check that the shims used to adjust the play have been
inserted.
3. Install the stopper bolts and nuts for each pin, then grease the
pin.
