Recreational Vehicle Generator
3. Hold the engine Start/Stop Switch at START to crank engine.
Release the switch when the engine starts.
CAUTION: If the engine does not start after it has
been cranking for 15 seconds, release the
start/stop switch and try again. Holding the switch
for longer than 15 seconds can damage the starter
motor.
4. Let the engine run at no-load for a few minutes to stabilize
and warm up.
5. Turn ON electrical loads, using whatever means provided
(such as a main circuit breaker or transfer switch).
STOPPING THE GENERATOR
1. Turn OFF all electrical loads, using whatever means pro-
vided (such as a main circuit breaker or transfer switch).
2. Let unit run a few minutes to stabilize temperature.
3. Hold the Start/Stop switch in its STOP position until engine
comes to a complete stop.
APPLYING LOADS TO GENERATOR
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.
LET ENGINE STABILIZE
The generator supplies correct rated voltage only at proper
governed speed. Some electrical appliances may be extremely
sensitive to voltage. Incorrect voltages can damage those
appliances.
If electrical loads are applied at reduced operating speeds,
such loads imposed on the engine when sufficient power is not
available may shorten engine life. Never turn ON electrical
loads until after the generator engine has started and stabi-
lized ON-speed.
DO NOT OVERLOAD THE GENERATOR
You can read the rated wattage/amperage capacity of your gen-
erator on the generator data decal (see “Identification Record”
on Page 3).
Applying electrical loads in excess of the unit’s rated capac-
ity will cause the engine-generator to automatically shutdown.
To avoid overloading, add up the wattage of all connected elec-
trical 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.
