Seat Switch System (If Equipped) 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 derectional lever and 
with the park brake released. You will note that 
the truck will move slowly in the selected 
direction. If you lift yours hips off of the seat, 
within three seconds, the SEAT SWITCH 
SYSTEM will desengage 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 
Infracore lift truck parts. Lift trucks should never 
be operated without an operational SEAT 
SWITCH SYSTEM.
