MAINTENANCE PROCEDURE

WARNING
It is dangerous if the work equipment moves by mistake when the teeth
are being replaced.
Set the work equipment in a stable condition, then stop the engine and
set the lock lever securely to the LOCK position.
The pins can be knocked out only with strong force, so there is a hazard
that the pin may fly out. Check that there is no one in the surrounding
area.
There is a hazard that fragments will fly during the replacement work, so
always wear protective equipment like safety glasses and gloves.
Replace the bucket teeth before the adapter starts to wear.

bottom surface of the bucket on a block, check that the work
equipment is in a stable condition, then set the lock lever to the
LOCK position.
Set so that thebottom face of the bucket is horizontal.
2. Use a hammer and drift to knock out lock pin (2). (If the drift is
set against rubber pin lock (3) when it is hit, the rubber pin lock
may break. Set it against the back of the pin.)
3. After removing lock pin (2) and rubber pin lock (3), check them.
If lock pins and rubber pin locks with the following defects are used, the teeth may come off the bucket. Replace
them with new ones.
The lock pin is too short.
