Seat Switch System
The lift truck is equipped with a SEAT SWITCH
SYSTEM. In normal operation if the direction lever is
placed in either forward or reverse, the lift truck will
move at a speed proportional to the accelerator
pedal's position. If the operator leavers the seat
without setting the parking brake, within three
seconds after leaving the seat, the SEAT SWITCH
SYSTEM will automatically disengage the
transmission. The directional lever, however, will
remain in that forward or reverse location although
internally the transmission will have shifted into
neutral.
Before exiting the lift truck, the parking brake should
always be applied.
WARNING
WHEN LEAVING MACHINE APPLY PARKING
BRAKE!
PARKING BRAKE IS NOT AUTOMATICALLY
APPLIED.
NOTE: Some trucks may be equipped (ask your
dealer if this applies to your truck) with an
alarm that will sound if the parking brake is
not applied when leaving the machine.
NOTICE
1. Prior to operating the lift truck, be sure to
understand and check the SEAT SWITCH
SYSTEM.
2. While in normal operation and on level ground,
select a direction with the directional lever and
with the park brake released. You will note that
the truck will move slowly in the selected
direction. If you lift your hips off of the seat,
within three seconds, the SEAT SWITCH
SYSTEM will disengage the transmission
allowing the truck to coast but not automatically
stop.
3. To restore the lift truck to normal operation,
while sitting in the operator's seat depress the
brake pedal to hold the lift truck, return the
directional lever to the neutral position, and then
reselect a direction of travel (either forward or
reverse). The transmission will then re-engage.
4. If seat or seat switch replacement becomes
necessary, be sure to use genuine DOOSAN
Industrial Vehicle lift truck parts. Lift trucks
should never be operated without an
operational SEAT SWITCH SYSTEM.
