2-4. POWER DRIVE CONTROL HANDLE.

2-4.1. Control Handle.

Two triangular shaped speed controls provide for easy
thumb actuation. Controls include an infinitely variable
forward and reverse speed control, a belly-button
reversing switch, and a horn. See

2-4.2. Steering Arm Controls.

Lowering the steering arm to the horizontal or raising
to the vertical applies the brake (See
traction control power is shut off when the brake is
engaged. When the steering arm is in the upright posi-
tion, the brake acts as a parking brake. Deadman
braking occurs when the handle is released and spring
action raises it to the vertical position.
When the lower portion of the triangular speed control
knob is pressed forward, contacts are closed for first
speed in the forward direction. Pressing the speed
control farther closes a contact for second speed and
farther, third speed. Pressing the upper portion of the
speed control governs the three reverse speeds in the
same manner.

2-4.3. Driving and Stopping Procedures.

The following procedure describes driving and stop-
ping the PDBB-20-T12 lift truck.
1. Turn the key switch to the on position.
2. Grasp the grips of the steering arm so that the
speed control can be comfortably operated by the
thumbs.
3. Lower the steering arm to a comfortable position
above horizontal to disengage the brake and to
energize the electrical circuits.
4. To move forward, slowly press the lower portion of
the speed control. Press the forward speed con-
trol farther to increase speed.
5. To stop, release the speed control and lower the
steering arm to the horizontal position. In this
position, the electrical brake activates.
The brake may also be applied by raising the
steering arm to the upright position.
6. To travel in reverse, lower the steering arm to a
comfortable position and slowly press the upper
portion of the speed control.
NOTE: Acceleration in reverse is the same as in the
forward direction.
