first. Ask your Komatsu distributor to perform this work.
METHOD FOR CHECKING ALTERNATOR AND STARTING MOTOR
The brushes may be worn or the bearing may have run out of grease, contact your Komatsu distributor for in-
spection and repairs.
If the engine is started frequently, have this inspection performed every 1000 hours.
