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 slowly release the
service brake.
4. Engage the parking brake and shift the
transmission to NEUTRAL. Slowly release the
service brakes.
5. The parking brake adjustment is proper if it holds
the lift truck on the grade. The parking brake
needs adjusting if it does not hold the lift truck on
the grade.
6. 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
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.
Parking Brake Adjusting
1. Park the lift truck on a level surface, lowered the
forks, shift the transmission to NEUTRAL and
shut OFF the engine and block the wheels
securely.
2. Chock the lift truck's tires to prevent unintentional
movement.
3. Remove the floor mat and floor plate.
4. Make sure the parking brake lever is released.
5. Make sure the brake lever (1) is held against stop
pin (2). If the brake lever (1) is held against the
stop pin (2), go to step 7. If the brake lever (1) is
NOT held against the stop pin (2), go to step 6.
