REPLACE BUCKET TEETH (XS) 4
Replace teeth
Replace the bucket teeth before the adapter starts to wear.
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
There is a hazard that fragments will fly during the replacement work, so always wear protective equip-
ment like safety glasses and gloves.
q
If the tooth pins cannot be removed in this procedure, for safety's sake, be sure to ask your Komatsu
distributor for the replacement.
NOTICE
q
When replacing the bucket teeth, be sure to replace all of them at once. Should all the bucket teeth be
not replaced at a time, the bucket will likely be deformed.
q
In order to prevent a tooth from slipping off, also replace the pins with new ones when replacing the
teeth.
Prepare for a socket wrench for 16 mm- width across flats.
1. Set the bucket with the bottom of the bucket on block (3) so
that pin (1) can be removed, then stop the engine.
2. Within 15 seconds after stopping the engine, move each
control lever (for work equipment and travel) to the full
stroke in all directions to release the internal pressure.
3. Check that the work equipment is in a stable condition,
then set the lock lever to the LOCK position (L).
