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 top-mounted control handle assembly is used on these
lift trucks and is designed to be used while the operator is
either walking beside the truck or riding on a small
platform to the left or right side of the handle. A power
assist option is available that senses when the operator
begins to move the control handle side to side and activates
a motor in the drive unit compartment to turn the drive unit.
This greatly reduces the operator effort needed to steer the
lift truck.
ACCESSING THE DRIVE UNIT
COMPARTMENT
The drive unit compartment is concealed behind a molded
cover which fits securely around the steer support assembly
and into the frame. The floor mat fits snugly in the operator
platform after the drive unit cover has been installed.
To remove the drive unit cover, first lift the corners of the
floor mat and pull it out away from the drive unit. See
Figure 1. Next, reach under the side of the drive unit cover
near the bottom and find the grip slot. See Figure 2.
With both hands, pull up and away from the truck until the
bottom of the cover kicks out from the retaining clips.
Repeat this for the other side of the cover. Work around the
edge of the cover until it is freed from the truck.
To install the drive unit cover, make sure the floor mat is
pulled away from the drive unit and place the bottom of the
drive unit cover onto the operator platform. Position the
lower edges partially into the lower retaining clips. Push
the top of the cover partially into the upper retaining clips.
Do not push either edge of the cover in completely before
starting all edges into the proper place. When the cover is
aligned and started properly, press the cover completely
into the retaining clips and place the floor mat into the
operator platform around the cover.
