General

The control handle assembly is designed to perform
several functions. The standard control handle
includes the speed/direction control and buttons for
the horn, traction reversing, and hydraulic functions.
The control handle is connected to the Master Drive
Unit (MDU) and is used to steer the truck as it turns
the MDU. Move the control handle left or right to turn
the drive/steer tire and steer the truck. Controls
mounted in the handle are linked to the control panel
by a wiring harness that passes through the center of
the handle. The brake is applied when the handle is in
the full up or down position.

A bottom-mounted control handle assembly is used
on the MSW020/025-E, MSW025/030-F, MPB040-E,
MPW045-E, and MPW050-E. The handle is designed
to be used while the operator is walking beside the lift
truck.

connect the battery.

2. 

Discharge the capacitors in the controllers by con-
necting  a  200-ohm,  2-watt  resistor  across  the
controller's  B+  and  B−  terminals. 

DO  NOT

  short

across  the  motor  controller  terminals  with  a
screwdriver or jumper wire. See Figure 1 and Fig-
