4. Continue to pump in grease until (S) becomes 48 mm (1.9 in).
If the tension is still loose, the pin and bushing are exces-
sively worn, so they must be either turned or replaced. Please
contact your Komatsu distributor.
Loosening Track Tension
WARNING
It is extremely dangerous to release the grease by any method except the procedure given below.
If the track tension is not relieved by this procedure, please contact your Komatsu distributor for repairs.
1. Loosen plug (1) gradually to release the grease.
2. Turn plug (1) a maximum of one turn.
3. If the grease does not come out smoothly, move the machine
forwards and backwards a short distance.
4. Tighten plug (1).
5. To check that the tension is correct, move the machine slowly
forward.
6. Check the track tension again, and if the tension is not cor-
rect, adjust it again.
CHECK ELECTRICAL INTAKE AIR HEATER
4
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.
Remove the electrical intake air heater from the engine intake manifold, and check it for possible disconnections
and dirt.
When inspecting and replacing the electrical intake air heater, replace the gasket with new one.
