2-4. GENERAL CONTROL OPERATION.
The speed control (See Figure 2-3 ) located on each
side of the control head provides fingertip control for
driving the truck. Rotate the control in the direction you
want to travel. The farther you rotate the control from
the neutral position, the faster the truck will travel.
Figure 2-3. Forward/Reverse Control
The pushbutton switches (See Figure 2-4 ), located on
the front of the control head activate the lift, lower, tilt
and horn.

2-5. DRIVING AND STOPPING PROCEDURES.
1. Connect the batteries and turn on the key switch.
Grasp the grips of the steering head so that the
speed control can be comfortably operated by
either thumb.
2. Lower the steering arm to a comfortable position
above horizontal to disengage the brake and to
energize the electrical circuits. If the truck is not
moved, the electrical circuits will time out and will
deenergize. See
Figure 2-5 .
3. To move forward (with load in front), slowly press
the speed control forward. See
Figure 2-3 . Press
the forward speed control farther to increase
speed.
4. To slow down or stop, release the speed control
and lower or raise the steering arm to the horizon-
tal or vertical position. See
Figure 2-5 . In those
positions, the brake engages, slowing or stopping
the truck.
5. Procedures for movement in reverse are the
same as in the forward direction except slowly
press the speed control backward. See
Figure 2-
3 .
2-5.1. Stopping
The brake pattern of the truck depends on the ground
conditions. The driver must take this into account
when operating the truck.
The driver must be looking ahead when traveling. If
there is no hazard, brake moderately to avoid moving
the load.
There are four different ways to stop the truck:
1. Plugging : This electrical braking function con-
sists of rotating the speed control lever in the
opposite direction of travel and then releasing it
when the truck stops. Plugging is a convenient
way to stop the truck during normal operation. If
the control is not released, the truck will acceler-
ate in the opposite direction.
2. Steering arm (See Figure 2-5 ) : The brake is fully
applied by lowering or raising the steering arm.
(See
Figure 2-5 ) All traction control power is shut
off when the brake is engaged. When the steering
arm is in the upright position, the brake acts as a
parking brake. Deadman braking occurs when the
handle is released and spring action raises steer-
ing arm to the upright position.
3. Emergency braking : Press the emergency brake
switch, all electrical functions are cut out and the
truck automatically brakes.
4. Regenerative braking: If the speed control lever is
released, the truck automatically brakes regener-
atively. When the speed is below .5 MPH, the
brake applies
