Brake Switch Operation
The brake is applied when the control handle is in the full
up or full down position. The brake is released by lowering
the control handle to the Brake Off (operating position) and
selecting a direction with the speed/direction control. Re-
gen braking is activated when the control arm approaches
full up or full down position. This slows the truck using the
traction motor before applying the parking brake. See Fig-
ure 8. The parking brake is controlled by a switch(es)
and/or a potentiometer (depending on model) that monitors
the control arm position. If the parking brake does not re-
lease or apply properly, check the operation of the brake
switches and/or potentiometer.
