The oil pressuregaugegivessome indication of the oil condi-
tion once it is at operating temperature. Pressure drops
between oil changesmay be causedby oil dilution, a clogged
crankcase suction strainer, or an internal engine oil leak.
Always determine the cause of decreasednormal engine oil
pressure.
CD
Engine Coolant Temperature Gauge
This gaugeshows the temperature of the coolant circulating
through the engine. After the engine hasoperated a sufficient
length of time, the pointer of the gaugemust be in the "RUN"
(green) range.
During normal operation, the gauge readings should vary
between the minimum and maximum indicated by the
"RUN"
segment of the gauge.
Continuous engine operation below the minimum tempera-
ture is harmful to the engine oil. Low coolant temperatures
will also cause exhaust smoke and increasethe rate of fuel
consumption.
NOTE: In cold weather, it may be necessaryto cover
part of the radiator to maintain the minimum coolant
temperature indicated at the lower end of the" RUN"
segment.
Overheating indicates the need for mechanical correction. A
clogged cooling system or a low coolant level will alsocause
high operating temperatures. The engine temperature, under
full-load conditions, should remain below the maximum
reading listed.
CD
Rear Driving Lights Circuit Fuse
This fuse protects the rear driving lights circuit. Refer to
"ELECTRICAL
SYSTEM"
in Section 8 for additional
information on fuses.
CD
Tail Light Circuit Fuse
This fuse protects the tail lights circuit. Refer to "E LEC-
TRICAL SYSTEM" in Section 8 for additional information
on fuses.
CD
Starting Aid Plunger
(If
equipped)
The starting aid plunger injects ether into the engine when
pressed down. The ether aids in starting the engine during
cold weather.
NOTE: The starting aid plunger should be used only
when the air temperature is below freezing (+32 degrees
F.l.
Refer to "STARTING THE ENGINE" in Section 5 for
operation of the starting aid.
eD
Stop Light Circuit Fuse
The fuse inside of this holder protects the stop lights circuit.
Refer to "ELECTRICAL SYSTEM" in Section 8 for addi-
tional information on fuses.

CD
Heater and Air-Conditioner Circuits Fuse
The fuse inside of this holder protects the heater circuit or
the air-conditioner circuit, depending on which is being used
at the time. Refer to "ELECTRICAL SYSTEM" in Section 8
for additional information on fuses.
CD
Parking Brake Warning Light
This light will flash on and off if the parking brake is applied
when the electrical combination switch is turned on. A
buzzer will also sound intermittently.
The parking brake warning light will continue to flash un-
til the parking brake is fully releasedat 85 psi air pressure.
NOTE: Do not operate the machine with the parking
brake applied.
For bulb replacement, refer to "ELECTRICAL SYSTEM" in
Section 8.

Air PressureGauge
This gaugeregistersthe amount of air pressurein the air tank.
Tap the gaugelightly when checking the gaugereading. The
unit should not be moved until the gaugeis registering in the
"RUN" (green) segment of the gauge. The left side of the
"RUN" segment is approximately 75 psi and the right side
approximately 125 psi.
