WARNING
ALWAYS make sure the parking brake is fully applied
before leaving the lift truck. If the operator leaves the
lift truck without applying the parking brake, a seat
activated switch will cut off all electrical and hydraulic
power to the lift truck.
The lift trucks covered in this manual are equipped with an
Operator Presence System (OPS). The OPS feature has
an electrical sensor switch in the seat which senses the

delay in the seat switch to allow the operator to reposition
himself without disabling all hydraulic and electrical func-
tions.
The operator must be on the seat before turning the key or

to provide power to the lift truck. If the
operator leaves the seat while the truck is moving, or does
not apply the parking brake before getting off the seat, the
seat switch will cut off power to the lift truck.
