3. Connect the other end of the red jumper cable to the
positive (+) terminal of the heater trailer battery.
4. Connect the one end of the black jumper cable to the
negative (-) terminal of the booster vehicle battery.
5. Connect the other end of the black jumper cable to an
unpainted surface of the heater trailer engine or chassis.
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 heater
trailer engine or chassis 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 the booster
vehicle battery. Do not let the cable ends touch any
metal or each other.
Engine Monitor and Control Center
The engine monitor and control center (Figure 20) monitors
critical engine functions, and controls engine speed.
Turning the key switch to the RUN position powers up the
engine monitor and control center. Once the engine is start-
ed, the following information is displayed on the monitor:
A
. Coolant Temperature *
B
. Engine RPM *
C
. Oil Pressure *
D
. Battery Voltage
E
. Fuel Level (% of max tank capacity) *
F
. Hourmeter
The control center adjusts the engine RPM range from 1000
to 1800, in increments of 50 RPM.
G
. Increase Engine RPM
H
. Decrease Engine RPM
NOTE: The ‘Menu’ (
I
) and ‘Enter’ (
J
) buttons have been pre-
set at the factory, and should not be touched.
* Engine shutdown will occur in the event of:
• High coolant temperature (>245° F (118° C))
• High engine RPM (>1800)
• Low oil pressure (<15 psi)
• Low fuel level (<15%).

Automatic Engine Shutdown System
The engine is 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 tem-
perature.
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 (Shocker
Valve)
The heater trailer is equipped with an engine air intake shut-
off valve (shocker valve). The 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. Start the engine. See ‘Operatng The Engine’.
3. Locate the covered switch on the right side of the control
panel. Lift the cover and move the switch to the up posi-
tion. 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 shut down immediately, shut the
machine down with the key switch, and do not use the
machine. Close the cover on the switch to reset the
switch to the operational mode. Tag the machine “Do not
