General
This model material handler is equipped with a powershift transmission. With
this type of transmission, the operator simply selects a gear, selects the direction
of travel, releases brakes and depresses the accelerator pedal to move the
handler.
Operation
Gear Selection: A four-speed transmission is used on this machines. This
transmission has four forward gears and three reverse gears.
Gear selection is accomplished by rotating the twist grip handle on the
transmission control lever. It is best to begin travel in a lower gear, however
the machine will move away from rest in any gear. Upshifts are most smoothly
accomplished by lifting off the throttle pedal when shifting. Caution should be
taken of downshifting to ensure that the ground speed of the material handler
has slowed sufficiently so as not to over-speed the engine.
Select the appropriate gear for the task being performed. Use a lower gear
when transporting a load. Use a higher gear only when traveling longer distances
without a load. When traveling through deep mud, or up slopes, use a lower
gear. Downshift a gear when traveling down a long hill. Use the service brakes,
if necessary, to prevent over-speeding the engine.
Direction of Travel: Direction of travel is selected by moving the transmission
control lever towards the front of the machine for forward travel, and towards
the rear of the machine for reverse travel. Neutral is selected by moving the
transmission control lever to the center position. If neutral is selected while
the machine is moving, the machine will continue rolling in the direction of
travel.
Always bring the machine to a complete stop before changing direction of
travel. This will prevent damage to the transmission or torque converter.
Forward or reverse travel can be selected while in any gear. If reverse is selected
while in fourth gear, the transmission will automatically default to third gear. If
forward is selected again, the transmission will go back to fourth gear.

of travel could reduce stability and/
or cause load to shift or fall.
