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 generator 
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 dur-
ing motor starting). Be sure to allow for this when 
connecting electrical loads to the generator. First, 
figure the watts needed to start electric motors in 
the system. To that figure, add the running watt-
ages 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.

‹

This switch (Figure 2.2), which has normally open 
(N.O.) contacts, is mounted near the oil filter. The 
contacts close if the temperature should exceed 
approximately 284º F (140º C), initiating an engine 
shutdown.
