ENGINE COOLANT TEMPERATURE GAUGE
The engine coolant temperature gauge registers the
engine coolant temperature. Normal engine coolant
temperatures range up to 200
_
F (93
_
C).
Temperatures above this level indicate an
over-heating engine. This condition may arise due to
a low coolant level, a clogged radiator, a loose fan
belt, a defective thermostat, or other engine
malfunctions. Engine over-heating will always cause
a coolant loss. If coolant loss does not occur, check
for malfunction of the temperature sending unit.
ENGINE OIL PRESSURE GAUGE
The engine oil pressure gauge registers the engine
oil pressure. Normal engine oil pressure ranges from
25 to 45 psi (170 to 310 kPa) on gasoline and LPG
powered machines, and 30 to 65 psi (205 to 450
kPa) on diesel powered machines at full engine
throttle. If the gauge registers an oil pressure reading
below these ranges, stop the engine immediately
and determine the cause. Failure to stop the engine
will result in engine damage.
BATTERY CONDITION GAUGE
The battery condition gauge indicates the present
voltage potential of the battery when engine is not
operating. Normal battery voltage is 10 to 14 volts.
When the engine is operating, the gauge registers
alternator output voltage. If the voltage exceeds
14 volts, it may be overcharging. If the voltage falls
below 10 volts, it may not be accepting or getting a
charge from the alternator. Overcharging and
undercharging are indications that one or more
electrical components are in need of repair.
IGNITION SWITCH
The key-operated ignition switch starts the
engine.
Gasoline and LPG powered machines: To start the
engine, turn the key fully clockwise. Release the key
as soon as the engine starts.
NOTE: Do not operate the starter motor for more than
10 seconds at a time or after the engine has started.
Allow the starter to cool between starting attempts.
The starter may be damaged if it is operated
incorrectly.
Diesel powered machine: Turn the partially clockwise
to turn the ignition on. Depress the diesel preheat
pushbutton for 15 to 30 seconds. Turn the key fully
clockwise to start the engine. If the engine fails to
start, try the preheat pushbutton again.
FOR SAFETY: Before starting machine make sure
all safety devices are in place and operate
properly.
SIDE BRUSH POSITION LEVER
The side position lever controls the position of the
side brush.
To lower the side brush, pull the lever back and to
the left into the (Side Brush Down) position. To
raise the side brush, pull the level back and to the
right into the (Side Brush Up) position.
NOTE: Always raise the side brush when the machine
is not being operated for a period of time to prevent
the side brush from taking a set.
HOPPER SUPPORT BAR
The hopper support bar is located on the operator’s
side of the hopper. It holds the hopper in a “raised”
position to allow work to be done under the hopper.
Do not rely on the machine hydraulic system to keep
the hopper raised.
WARNING: Falling hopper. Engage hopper
support bar before working under hopper.
TO ENGAGE HOPPER SUPPORT BAR
1. Set the machine parking brake and start the
engine.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, set parking brake,
and turn off machine.
2. Raise the hopper to the fully raised position.
3. Lift and position the hopper support bar under
the hopper lift arm pin on low dump models, or
hopper lift arm cam on multi-level dump
models.
