To jump start the engine:
WARNING
Allowing the ends of the jumper cables to touch each
other or metal surfaces while connected to a battery could
cause sparks that may ignite battery gases resulting in
death or serious injury. Always keep jumper cable ends
from touching each other or metal surfaces while connect-
ing or disconnecting them.
1. To gain access to the battery, open the rear engine
access door and secure with the door cover holders.
2. Connect one end of the red jumper cable to the positive
(+) terminal of the booster vehicle.
3. Connect the other end of the red jumper cable to the
positive (+) terminal of the heater trailer.
4. Connect the one end of the black jumper cable to the
negative (-) terminal of the booster vehicle.
5. Connect the other end of the black jumper cable to an
unpainted surface of the engine of the heater trailer.
6. Make sure that the jumper cables are not near any mov-
ing parts of either engine.
7. Start the engine of the booster vehicle and let it idle for
several minutes.
8. Start the engine of the heater trailer and let both engines
run for several minutes.
9. After the engine has started and stabilized, remove the
jumper cables in the reverse order. Remove the black
jumper cable from the unpainted surface of the engine in
the heater trailer first. Do not allow the end of this cable
to touch any metal or other jumper cable ends.
10. Remove the remaining cables starting with the black
jumper cable at the negative (-) terminal of the booster
vehicle battery, then the red jumper cable from the posi-
tive (+) terminal of heater trailer battery and finally the
red jumper cable from the positive (+) terminal of booster
vehicle battery. Do not let the cable ends touch any
metal or each other.
Automatic Engine Shutdown System
Both the Caterpillar C1.5 engine and the Isuzu C3E engine
are equipped with an automatic engine shutdown system.
This system will automatically shutdown the engine in the
event of low engine oil pressure or high coolant temperature.
If the engine has automatically shutdown, locate the source
of the failure and repair the failure before re-starting the
engine.
Engine Air Intake Shut-Off Valve
The heater trailer can be equipped with an optional engine air
intake shut-off valve. This option is available with either the
Caterpillar or Isuzu engines.
The engine air intake shut-off valve is intended to prevent the
diesel engine from going into an overspeed condition in the
event that flammable gas or vapor is present at the engine air
intake. Should an overspeed condition occur, the engine air
intake shut-off valve automatically closes preventing air from
getting into the cylinders, thereby stopping the engine.
The engine air intake shut-off valve is intended only to protect
the engine against damage from overspeed conditions. It
is not intended to be used as any part or indicator for a per-
sonal protective device, nor does it provide an indication of
whether an area is safe from flammable or explosive gas.
The engine air intake shut-off valve should be tested daily.
To test the engine air intake shut-off valve:
1. Open the rear engine cover door and secure with the
door cover holders.
2. Start the engine. See ‘Starting The Engine’.
3. Locate the red covered switch at the back of the engine
control panel. Lift the cover and move the switch to the
up position. The engine should shut down immediately.
If the engine shuts down, close the red cover on the
switch to reset the switch to the operational mode.
4. If the engine does not shutdown immediately, shut the
machine down with the key switch, and do not use the
machine. Close the red cover on the switch to reset the
switch to the operational mode. Tag the machine “Do not
operate”, and notify your service or maintenance depart-
ment to get the machine repaired.
To reset the engine air intake shut-off valve:
DANGER
Resetting and re-starting the engine after the engine
air intake shut-off valve has automatically shutdown the
engine could ignite an explosive atmosphere that will result
in death or serious injury. Always leave the area immedi-
ately when the engine air intake shut-off valve automati-
cally shuts down the engine, and do not return until safety
and supervisory personnel have given an “all clear” to
return to the area.
1. If the air intake shut-off valve has tripped and shutdown
the engine automatically, leave the area immediately and
follow the safety instructions and procedures for your job
site. Do not reset or restart the engine until the source of
the problem has been determined, and safety and super-
visory personnel at your job site have given an “all clear”
to return to the area.
2. When permission is given to return to the area where the
heater trailer is located, open the rear engine cover door
and secure with the door cover holders.
3. Locate the blue knob on the engine air intake shut-off
valve. Turn the knob so that it aligns with the intake
hoses to and from the valve body. You will hear and feel
a distinct “click” as the engine air intake shut-off valve is
reset to the operating position.
