automatically disable all hydraulic and electrical functions
so that the lift truck cannot travel forward or backward
when the operator is not on the seat. If the lift truck can
travel forward or backward, or the hydraulic functions oper-

This lift truck may be equipped with an optional operator
presence system which will not allow the truck to travel
unless the seat belt is fastened. When equipped, a seat
belt interlock includes sequencing/logic for the seat pres-
sure switch and seat belt switch. The weight of the operator
must be detected prior to the seat belt switch being
engaged to enable operations.
Oil Leaks
Visually check the hydraulic system, steering system, brake
system, and transaxle for leaks.
How to Charge the Battery
WARNING
The acid in the electrolyte can cause injury. If electro-
lyte is spilled, use water to flush the area. Make the
acid neutral with a solution of sodium bicarbonate
(soda) and water. Acid in the eyes must be immediately
flushed with water.
Batteries generate explosive fumes when they are
being charged. Keep fire, sparks, and burning material
away from the battery charger area. Prevent sparks
from the battery connectors.
Charge batteries only in the special area for charging
batteries. When charging the batteries, keep the vent
caps clean. The battery charger area must have ventila-
tion so that explosive fumes are removed. Open the
hood over the battery or remove the cover if the battery
has a cover.
Disconnect the battery when doing cleaning and main-
tenance.
