Parking Brake
NOTE: The parking brake is required to be
adjusted to hold the lift truck with capacity
load on a 15% grade.
If there is a 15% grade in your workplace,
engage a capacity load and drive over to
the grade. If the maximum grade in your
workplace is less than 15% or if the
maximum load carried by the lift truck is
less than the lift truck's load capacity, pick
up the maximum load and drive to the
steepest grade in your workplace.
1. Raise the forks or load engaging attachment
about 30 cm (12 in) from the floor.
2. Drive forward up the grade, or in reverse down
the grade, and stop the lift truck with the service
brakes.
3. Engage the parking brake and release the
service brakes.
4. If the lift truck moves down the grade, control its
speed with the service brakes, release the
parking brake and
inspection area.
5. Park the lift truck, engage the parking brake, shift
the direction control lever to NEUTRAL, lower the
forks or load engaging attachment to the floor,
shut OFF the engine, remove the key, chock the
tires, terminate the inspection, tag the lift truck
"Do Not Operate" and immediately report the
failure of the parking brake to hold the lift truck.
