Parking Brake Testing
NOTICE
OSHA requires the parking brake to hold the lift truck,
with capacity load, on a 15% grade.
Testing requires a test load equal to the capacity of the
truck and a 15% grade.
If the maximum grade in the workplace is less than its
capacity, use the Parking Brake inspection procedure
covered in ‘Inspection from Operator’s Seat, Engine
On’ in “Every 10 Service Hours or Daily” section.
1. Pick up capacity load and drive over to a 15%
grade.
2. Drive forward up the 15% grade. Halfway up the
grade, stop the lift truck with its service brakes.
3. Engage the parking brake and shift the
transmission to NEUTRAL. Slowly release the
service brakes.
4. The parking brake adjustment is proper if it holds
the lift truck on the grade.
5. If the lift truck starts to move in reverse down the
grade with the parking brake engaged, stop it with
the service brakes, disengage the parking brake
and reverse slowly down the grade controlling
your speed with the service brakes.
WARNING
If the parking brake is used for emergency braking
while the vehicle is running, the parking brake must
be tested.
If the forklift continues to move even when the
parking brake is on, park the vehicle in a safe place
and insert a block of wood underneath the wheel to
prevent the vehicle from moving. Then contact the
service center and have the vehicle serviced.
WARNING
To prevent personal injury, the operator MUST be
ready to use the service brake if the parking brake is
not adjusted correctly and the lift truck starts to
move.
