XI. OPS (Operator Presence Sensing) system instruction
OPS system (only limited to electric reversing hydraulic trucks)
The OPS (Operator Presence Sensing) system is mainly used for safety, when the operator is not in the
correct driving position, the forklift cannot be driven and transported, thereby reducing accidents
caused by misuse.
Forklift truck shutdown conditions
When the driver leaves his/her seat or his/her safety belt is loose (if the safety belt protection switch
is provided) and the hand brake is not engaged, the buzzer will sound an alarm.
Without the safety belt protection switch: When the driver sits back on the driver's seat properly or
engages the hand brake, the buzzer alarm will turn off.
With the safety belt protection switch: When the driver first sits back on the driver's seat properly and
fastens his/her safety belt or engages the hand brake, the buzzer alarm will turn off.
Forklift truck start conditions
1. Start
The forklift truck can be started normally when the driver sits on the driver's seat properly, fastens the
safety belt (if the safety belt protection switch is provided), or engages the hand brake, and pulls the
shift switch to the neutral position. If the shift switch is not pulled to the neutral position, the truck
cannot be started.
Caution
 If the forklift truck is parked on a ramp, you must press the brake pedal to the bottom to
start the truck to protect the truck from sliding.
2. Forward and backward protection
When you are ready to drive the forklift truck after the engine has started, you can start the truck
normally by pulling the shift switch to forward gear 1 or backward gear 1. If the shift switch is pulled
to forward gear 2 or backward gear 2 directly, the neutral indicator light will flash; if the truck cannot
be started, the shift switch should be returned to the neutral position to release protection.
When the driver leaves his/her seat or his/her safety belt is loose (if the safety belt protection switch
is provided) for more than 3s when the forklift truck is driving, the buzzer will sound an alarm, the
neutral indicator light will flash, the OPS indicator light will turn on, and the truck will be automatically
stopped.
When the driver sits on the driver's seat properly again, the buzzer alarm will turn off and the OPS
indicator light will turn off; when the shift switch is pulled to the neutral position, the flashing neutral
indicator light will become permanently lit; when the shift switch is pulled forward or backward, the
forklift truck will resume normal operation.
