To start the generator from either the generator con-
trol panel or from the optional remote panel, proceed 
as follows:

1.  Turn OFF electrical loads using the means pro-

vided in the vehicle (such as a main line circuit 
breaker or transfer switch).

NOTE:

If starting from the generator control panel, turn 
OFF loads by setting the generator’s main circuit 
breaker to the OFF (or open) position. If starting 
from a remote panel, turn OFF loads using the 
means provided in the vehicle (such as a main 
circuit breaker). Electrical load circuits will be 
turned ON after the generator has started, stabi-
lized and warmed up.

2.  If the engine has not been started in more than 

two weeks, press the Fuel Pump Primer switch 
and hold it for about 10 to 15 seconds to prime 
the fuel system. However, if the engine is warm, 
skip Step 2.

3.  Hold the engine Start/Stop switch in the  START 

position to crank the engine. Release the switch 
when the engine starts.

4.  Let the engine run at no-load for a few minutes to 

stabilize and warm up.

5.  Turn ON electrical loads using the means pro-

vided (such as a main circuit breaker or transfer 
switch).

1.  Turn OFF all electrical loads using the means 

provided (such as a main circuit breaker or 
transfer switch).

2.  Let generator run at no-load for a few minutes, to 

stabilize internal engine generator temperatures.

3.  Place the Start/Stop switch in its STOP position.

When applying electrical loads to the generator, 
observe these guidelines:

• Before applying electrical loads, let the generator 

stabilize and warm up for a minute or two.

•  DO NOT overload the generator.

The generator supplies correct rated voltage only at 
the proper governed speed. Some electrical appli-
ances may be extremely sensitive to voltage. Incorrect 
voltages can damage such appliances.

If electrical loads are applied at reduced operating 
speeds, such loads imposed on the engine when suf-
ficient power is not available may shorten engine life. 
Never turn ON electrical loads until after the genera-
tor engine has started and stabilized at no-load.

Read the rated wattage/amperage capacity of the 
generator on the generator data label (see "Generator 
Identification").

Applying electrical loads in excess of the unit’s rated 
capacity will cause the engine/generator to automati-
cally shut down.

To avoid overloading, add up the wattage of all con-
nected electrical lighting, appliance, tool and motor 
loads. This total should not be greater than the 
generator’s rated wattage capacity.

• Most lighting, appliance, tool and motor loads 

indicate their required watts on their nameplate or 
data plate. For light bulbs, simply note the wattage 
rating of the bulb.

•  If a load does not show its rated wattage, multiply 

that load’s rated VOLTS times AMPS to obtain 
WATTS.

•  Induction type motors (such as those that run the 

vehicle’s furnace fan, refrigerator, air conditioner, 
etc.) need about 2-1/2 time more watts of power for 
starting than for running (for a few seconds during 
motor starting). Be sure to allow for this when con-
necting electrical loads to the generator. First, fig-
ure the watts needed to start electric motors in the 
system. To that figure, add the running wattages of 
other items that will be operated by the generator.

•  Do not apply heavy electrical loads for the first two 

or three hours of operation.

This switch (Figure 2.2) has normally closed (N.C.) 
contacts that are held open by engine oil pressure dur-
ing cranking and operating. Should oil pressure drop 
below a preset level, switch contacts close, and the 
engine automatically shuts down. The unit should not 
be restarted until oil is added.
