OPERATION AND SPECIFICATIONS
BEFORE STARTING
1. Fill the engine with the proper grade of
lubricating oil (see pg. 11) and to cor-
rect level (check dipstick).
2. Ensure there is an adequate supply of
clean fuel, per appropriate EPA stan-
dards.
3. Ensure that the air cleaner is firmly
attached, and that the air canister
seals and the hose clamps are prop-
erly sealed. If the restriction gauge
indicates an obstructed air flow, the air
cleaner element should be checked
and replaced as necessary.
4. Install the ground rod.
DESCRIPTION OF OPERATION
By operating the start switch, the fuel so-
lenoid is energized. The solenoid plunger
is drawn into the coil and activates the fue!
control linkage to RUN position. When the
engine starts, adequate engine oil pres-
sure at the oil pressure switch will maintain
the solenoid in the energized position. The
start switch should be released as soon as
the engine starts. A 10A inline fuse pro-
tects the solenoid from electrical damage.
LOW OIL PRESSURE SHUTOFF
SYSTEM
Should a low oil pressure condition occur
(less than 5 PSI), the pressure sending
unit breaks the circuit between the battery
and the fuel solenoid, allowing the spring
load to immediately move the fuel control
to the shutoff position.
HIGH COOLANT TEMPERATURE
SHUTOFF SYSTEM
Should a high coolant temperature condi-
tion occur, the temperature sending unit
breaks the circuit between the battery and
the fuel solenoid, allowing the spring load
to immediately move the fuel control to the
shutoff position.
TIONS
STARTING KUBOTA AND
ISUZU ENGINES
NOTE: The Kubota and Isuzu engines in-
clude a glow plug cold start assist system
on the control panel. Glow plugs are not
needed on a warm engine or if the ambi-
ent temperature is above 50 F. Do not use
starting fluid or ether.
1. Turn the ignition power switch to the ON
position. Depress the glow plug button
for 3-5 seconds. NOTE: The glow plug
indicator lamp remains lit for as long as
the button is depressed, indicating that
electrical power is being supplied to the
glow plugs.
2. Push or rotate (as required) Start switch
until the engine starts. Release switch as
soon as the engine starts.
3. If engine fails to start it may be necessary
to cycle the glow plugs again.
NOTE: To prevent equipment damage, DO
NOT operate ignition switch for more than
10 seconds in the start position. If the en-
gine does not start in 10 seconds, wait 30
seconds and try the start sequence again.
Do not run the starter for more than 20
seconds continuously. Limit engine crank-
ing to 3 attempts with a 2 minute cool-
down between each attempt. After 3 at-
tempts allow starting system components
to cool to ambient temperature.
STOPPING KUBOTA AND
ISUZU ENGINES
1. Turn the ignition power switch to the OFF
position. This immediately breaks the
circuit between the battery and the fuel
solenoid, allowing the fuel control sole-
noid to move to the shutoff position.
2. Disconnect the ground rod, and stow
within the trailer.
