MAINTENANCE
SERVICE PROCEDURE
CHECK ELECTRICAL INTAKE AIR HEATER
Before the start of the cold season (once a year), contact your Komatsu distributor to have the electrical intake air
heater repaired or checked for dirt or disconnections.
REPLACE BUCKET TEETH
WARNING
It is dangerous if the work equipment moves by mistake when the tooth is being replaced.
Set the work equipment in a stable position, stop the engine, then set the safety lock for the work equipment control lever
securely to the LOCK position.
If the pin is hit out with strong force, there is danger that the pin may fly out. Check that there is no one in the surrounding area.
There is danger of pieces flying during the replacement operation, so always wear protective clothing such as safety glasses
and gloves.
BUCKET WITH TIP TOOTH
Replace the teeth before they wear down as far as the adapter.
1.
Raise the bucket to a suitable height, then put blocks under the
bucket to keep the bottom of the bucket horizontal.
2. Remove pin (2), then remove tooth (1).
When knocking out the pin, use a bar of a diameter slightly
smaller than the pin, and knock out from the opposite side.
REMARK
If it cannot be removed by this method, for safety reasons, always
contact your Komatsu distributor to have the replacement carried
out.
3. Fit new tooth (1) in adapter (3), push in pin (2) partially by hand,
then knock it in with a hammer.
4.
After operating for several hours, check that the pin has not
come out.
