WARNING
q
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.
q
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.
q
There is a hazard that fragments will fly during the replacement work, so always wear protective equip-
ment like protective eyeglasses and gloves.
1. To make it possible to knock out a pin of tooth (1), put block
(5) under the bottom of the bucket, and level the bottom of
the bucket.
2. Check that the work equipment is in a stable condition, then
set the lock lever to LOCK position (L).
3. 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.)
4. After removing lock pin (2) and rubber pin lock (3), check
them.
If lock pin (2) and rubber pin lock (3) are used in the condition
below, it will cause tooth (1) to come off during operation.
Replace them with new parts.
