OPERATION

REPLACEMENT AND INVERSION OF BUCKET

When knocking the pin in with a hammer, metal particles
●
may fly and cause serious injury, particularly if they get
into your eyes. When carrying out this operation, always
wear goggles, helmet, gloves, and other protective
equipment.
When the bucket is removed, place it in a stable condi-
●
tion.
Stop the machine on a firm, flat surface. When performing joint
work, make clear signals to each other and work carefully for
safety's sake.
REPLACEMENT
1. Place the bucket in contact with a flat surface.
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.

(B) and remove the bucket.
NOTICE
After removing the pins, make sure that they do not
become contaminated with sand or mud and that the seals of
bushing on both sides do not become damaged.
3. Align the arm with holes (1) and the link with holes (2), then
install pins (A) and (B).
