Stopping
Stop the truck as gradually as possible.
Unnecessary rapid stopping could be
hazardous. Load could become unsta-
ble.
You can use plugging to stop the truck,
this electrical braking function consists
of rotating the speed control lever in the
opposite direction of travel and then
releasing it when the truck stops. Plug-
ging is a convenient way to stop the
truck during normal operation. If the
control is not released, the truck will
accelerate in the opposite direction.
You can also stop the tucks movement
(forward or reverse) by raising the con-
trol handle to the up position or push the
control handle all the way down. In
either positions, the travel controls will
deactivate and the brake will apply. To
release the brake, just move the control
handle to the operating position.
NOTE: The steering arm gas spring
automatically raises the
steering arm to the upright
position when the steering
arm is released.
CAUTION: If the control handle does
not raise immediately to
the vertical position when
released, the truck should
be placed “OUT OF SER-
VICE” until it can be
inspected by a qualified
repair technician.
PDI,PDM,PDH (w. Dynamic Brakes):
The Dynamic Brake (if so equipped -
not
available on newer trucks
) serves as a
secondary braking system completely inde-
pendent from the mechanical brake. Press-
ing the dynamic brake pushbutton applies a
constant DC voltage across the drive motor
field coils to stop the motor.
The dynamic brake pushbutton
should not be held in place longer
than one or two seconds. Exces-
sive use may blow the 40 Amp
fuse, which will render dynamic
brake inoperative.
