LIFT TRUCK WASHING PROCEDURE
33.1
GENERAL PRECAUTIONS
When washing your lift truck, observe the following instructions to safeguard the truck.
Wet electrical equipment will result in the lift truck malfunctioning.
•
Before washing, ensure that the controller and all other electrical equipment sensitive to water is protected
from water or removed prior to washing and blowing dry. NEVER wash or wet down the areas inside the dash-
board.
•
Before washing, make sure that waterproof seals and covers are free from any deterioration and are fitted cor-
rectly in place.
•
When using a water stream, use compressed air, an air blower and dry wiping to dry the truck and remove
water droplets before using the truck connectors and electrical components. (Water droplets may run along the
wiring and enter the controller chamber, dashboard or seep into the connectors.)
•
If water does get into the controller chamber or dashboard, use a cloth or compressed air to remove the water
before using the truck.
•
When removing dirt from electronic parts (such as printed circuit boards), use a commercially available, spray-
type electronic equipment cleaner.

WASHING INSTRUCTIONS
If water gets into the electrical system (controller, sensor, connectors, etc.) it will cause malfunctions
or operational failure. Do not wash the electrical system with water or high-pressure steam.
1. Turn the starting switch key to the OFF position,
then remove the key.
2. Wash each part (1 to 4 parts in the figure at right),
following the instructions in the table on the
following page.
3. Dry off all wet areas with an air blower.
4. After checking that the washed parts have dried
out, insert the starting switch key and turn it to the
ON position, make sure that there is no abnormal-
ity, and then start operation.
