INITIAL START UP
The throttle control on these generators is preset and locked to operate
at 3600 RPM (nominal) with no load speed set at 3690 RPM. Only
a trained service technician should be allowed to adjust this speed
setting.
NOTICE: ENGINE START LOCKOUT
This unit will not start if it is low on oil. The lubricating oil level must be
at the full mark before the engine will start and run. This engine will not
start without a battery. The fuel shut-off solenoid requires 12V DC to
operate.
BASIC OPERATION
1. Check oil level, refill as needed.
2. Pull the choke rod out to the closed position.
3. Move the ON/OFF lever to the ON position
4. Pull the starter grip lightly until resistance is felt, then pull briskly.
CAUTION: EQUIPMENT DAMAGE
Do not allow the starter grip to snap back against the
engine. Return it gently to prevent damage to the starter.
5. If the choke rod was pulled to the closed position to start the engine,
push it to the open position as soon as the engine warms up enough to
run smoothly.
CAUTION: EQUIPMENT DAMAGE
Never permit the choke to remain in the on after the
engine has run for a short time. It is not necessary to
choke the engine when it is warm.. Avoid over-choking.
STARTING HINTS
1. COLD WEATHER
A. Use the proper oil for the temperature expected.
B. Use fresh winter grade fuel. Winter grade gasoline is blended to
improve starting. Do not use summer gasoline.
C. A slightly richer fuel mixture will usually improve cold starting.
CAUTION: EQUIPMENT DAMAGE
Never use ether or any other starting aides. Serious engine damage or
personal injury may result from ignoring this simple warning.
2. HOT WEATHER
A. Use the proper oil for the temperature expected.
B. Use only summer blended gasoline. Using gasoline left over from
winter may cause the unit to vapor lock.
STOPPING
1. Move the ON/OFF lever to the OFF position.
2. Before extended storage (over 30 days) certain precautions must be
taken care of to ensure the fuel doesn’t deteriorate and clog the fuel
system. Note: The use of a fuel additive, such as STA-BIL or an
equivalent will minimize the formation of gum deposits during
storage. Such an additive may be added to gasoline in the engines
fuel tank or to gasoline in a storage container.
A. Remove the remaining fuel from the fuel tank.
B. Start the engine and allow it to run until all the fuel in the
carburetor and the fuel lines has been used up and the engine
stops.
C. While the engine is warm, drain the oil and refill with fresh oil.
D. Remove the spark plug, pour approximately 1/2 ounce (15 cc)
of engine oil into the cylinder and crank slowly to distribute the
oil. Replace the spark plug.
E. Clean dirt and chaff from cylinder, cylinder head fins, blower
housing, screen and muffler areas.
F. Store in a clean and dry area.
OPERATING SPEED
All engines have a tendency to slow down when a load is applied.
When the electrical load is connected to the generator, the engine is
more heavily loaded, and as a result, the speed drops slightly. This
slight decrease in speed, together with the voltage drop within the
generator itself, results in a slightly lower voltage when the generator
is loaded to its full capacity than when running no load. The slight
variation in speed also affects the frequency of the output current.
This frequency variation has no appreciable effect in the operation of
motors, lights, and most appliances. However, electronic equipment
and clocks will be affected if correct RPM is not maintained. See Load
vs. Output chart.
