Operation - 27
Steering Wheel (S)
Turn the steering wheel to the left (counterclockwise)
to turn the power unit to the left. Turn the wheel to the
right (clockwise) to turn the power unit to the right.
Hydraulic Cooler Fan Switch (T)
The hydraulic oil cooler fan
switch is normally set to the
automatic thermostatically
controlled position (1). This
allows the thermostat to turn
on the cooling fan when the
hydraulic fl uid reaches the set
temperature. The fan pulls air
through the right fender next
to the operator, through the oil
cooler, and discharges the air
out the back of the power unit.
The switch can be set to the
reverse position (2) to pull air
from the back of the power
unit, through the oil cooler,
and discharge the warm air next to the operator.
This feature can be used to help provide warmth for
the operator during cold weather.
Seat Slide Lever (U)
Move the seat slide lever to the left to release the
seat lock. Move the seat forward or backward to the
desired position and release the seat slide lever to
lock the seat in place.
Fuel Shut-off Valve (V)
The fuel shut-off valve controls the
fl ow of fuel to the power unit engine.
Turning the valve to position 2 will
allow fuel to fl ow to the engine.
Turning the valve to position 1 shuts
off the fuel fl ow to prevent fuel leak-
age when changing fuel fi lters or
servicing the fuel system. Turn off the fuel shut-off
valve when transporting the power unit on a truck or
trailer and when parking the power unit indoors.

The circuit breaker/battery dis-
connect switch controls power
to the entire electrical system.
Turning the switch to position 2

seat forward. Lower the seat prop plate back into
the seat box and lower the seat back down to the
operating position.
Seat Latch Strap (Y)

The slope warning light works with the slope indi-
cator system to provide a visual warning when the
