brake switches toward the brake lever arm
until they actuate (click).
4.
Slowly depress the brake pedal while watching
the brake lever arm. The brake switches must
de-actuate after the pedal moves about one
inch. The contacts on the brake switches
should not be pressed all the way in when the
brake pedal is up. Readjust as needed, then
tighten the screws securing the brake
switches.
5.
Replace the control cover and top cover
6.
Connect the battery.
7.
Test the brake operation of the lift truck.
Disc Brake Air Gap
See Disc Brake Unit for adjustment procedures.
Braking Force (Clamping Pressure)
NOTE
This adjustment does not affect the air gap.
See Disc Brake Unit Assembly to set the air
gap.
The three adjustment screws in the top of each
disc brake unit are used to adjust clamping
pressure. Before adjusting these, verify that the
air gap is 0.008” to 0.015” for both brakes (see
Figure 2). Turn the screws clockwise to increase
clamping pressure; turn the screws
counter-clockwise to decrease clamping pressure.
Adjust all three screws on one brake unit the same
amount. Both brakes should apply equal pressure
so that the truck does not pull to one side during
braking. The brakes should stop a fully loaded
truck on a dry level surface in 1.1 feet per mile per
hour. For example, a truck traveling 6 MPH
should stop in about 6.6 feet when the brakes are
released.
NOTE
Clamping pressure adjustment is for minor
corrections only. If the braking distance is
excessive, check for other problems with the
brake units, such as contamination of the
friction plate.
