I – HOPPER DOOR SWITCH
The hopper door switch opens and closes the
hopper dump door. Pushing the front half of the
hopper door switch closes the hopper dump door.
Pushing the rear half of the switch opens the hopper
dump door. A beeper sounds when the door is in
the closed position. Sweeping should not be
attempted when the hopper door is closed.
J – HOPPER LIFT SWITCH
The hopper lift switch is used to raise and lower the
hopper during dumping operations. To raise the
hopper, press and hold the front half of the hopper
lift switch until the hopper has raised to the desired
height. Then release the switch. To lower the
hopper, press and hold the rear half of the hopper lift
switch until the hopper lowers to the normal
sweeping position.
FOR SAFETY:
The hopper lift switch will not raise
or lower the hopper if the key switch is in the off
position.
K – HOPPER SAFETY ARM
The hopper safety arm is used to support the hopper
in the raised position. The safety arm should be
used whenever inspection or service is performed
under the hopper. Do not rely on the hydraulic
cylinder to keep the hopper raised.
Raised hopper may fall. Engage hopper safety
arm before working under hopper.
L – ENGINE TEMPERATURE LIGHT
The engine temperature light indicates when the
engine is overheating. If the light comes on, stop
the engine immediately and determine the cause.
Failure to stop the engine will result in engine
damage. Some causes of engine overheating are a
clogged radiator, clogged cooling fins in the radiator,
loose fan belt or other engine malfunction. Consult
your Engine Owners guide to help determine the
problem.
M – OIL PRESSURE LIGHT
The engine oil pressure light indicates inadequate
engine oil pressure. If the light comes on, stop the
engine immediately and determine the cause.
Failure to stop the engine will result in engine
damage.
N – ENGINE GLOW PLUG LIGHT
(DIESEL ONLY)
The glow plug light is a time-controlled light that
allows the glow plugs to heat up sufficiently before
cranking the engine. When the ignition switch is
turned clockwise to the “RUN” position, the light will
come on. After 5-30 seconds, depending on
temperature, the light will go off. Then the engine
can be cranked with the ignition switch.
O – LIGHT SWITCH
The light switch operates the headlights and
taillights.
P – THROTTLE
The throttle is an adjustable, lockable tee-handle.
The handle is unlocked by turning counter-
clockwise, and locked by turning clockwise. Start
the engine with the throttle pushed all the way in.
When the engine has adequately warmed up, unlock
and pull the throttle all the way out and lock. This
will set the engine at the maximum governed speed.
The throttle may be adjusted and locked anywhere
between idle and max. if desired. Consult engine
service guide.
