OPERATION
CHECK THAT LAMPS LIGHTS UP
Check that the head lamp, rear lamp, additional working lamp (if equipped), and instrument lamp light up normally
and they are free from stain and damage.
If the lamps do not light up, there is probably a broken bulb or disconnection in the wiring, so contact your Komatsu
distributor for repairs.
1. Insert the key into starting switch and turn the key to the
ON position.
2. Turn the head lamp switch, the rear lamp switch and the
additional working lamp to the ON position and check
that the head lamps and rear lamps light up.
3. Turn the additional head and rear working lamp switches
(optional) to the ON position, and check that all the lamps
light up.
