death. If you start to feel dizzy or weak, get to
fresh air immediately.
Operate generator outdoors only in a well
ventilated area
DO NOT operate the generator inside any
building, including garages, basements,
crawlspaces and sheds, enclosure or
compartment, including the generator
compartment of a recreational vehicle.
DO NOT allow exhaust fumes to enter a confined
area through windows, doors, vents or other
openings.
DANGER CARBON MONOXIDE, using a
generator indoors CAN KILL YOU IN
MINUTES.
DANGER
Rotating parts can entangle hands, feet, hair,
clothing and/or accessories.
Traumatic amputation or severe laceration can
result.
Keep hands and feet away from rotating parts.
Tie up long hair and remove jewelry.
Operate equipment with guards in place.

Sparks can result in fire or electrical shock.
When servicing the engine:
Disconnect the spark plug wire and place it
where it cannot contact the plug.
DO NOT check for spark with the plug removed.
Use only approved spark plug testers.
WARNING
Running engines produce heat.
Severe burns can occur on contact.
Combustible material can catch fire on contact.
DO NOT touch hot surfaces.
Avoid contact with hot exhaust gases.
Allow equipment to cool before touching.
Maintain at least three feet of clearance on all
sides to ensure adequate cooling.
Maintain at least five feet of clearance from
combustible materials.

Safety Rules
4 Rev 61302-20090428
DANGER
Fuel and fuel vapors are highly flammable and
extremely explosive.
Fire or explosion can cause severe burns or
death.
Unintentional startup can result in entanglement,
traumatic amputation or laceration.
When adding or removing fuel
Turn the engine off and let it cool for at least two
minutes before removing the fuel cap. Loosen
the cap slowly to relieve pressure in the tank.
Only fill or drain fuel outdoors in a well-ventilated
area.
DO NOT overfill the fuel tank.
Always keep fuel away from sparks, open flames,
pilot lights, heat and other sources of ignition.
DO NOT light or smoke cigarettes.
When starting the engine

Make certain that the gas cap, air filter, spark
plug, fuel lines and exhaust system are properly
in place.
Allow spilled fuel to evaporate fully before
attempting to start the engine.
Make certain that the engine is resting firmly on
level ground.
When transporting or servicing the
engine:
Make certain that the fuel shutoff valve is in the
off position and the fuel tank is empty.
Disconnect the spark plug wire.
When storing the engine:
Store away from sparks, open flames, pilot lights,
heat and other sources of ignition.
WARNING
Rapid retraction of the starter cord will pull hand
and arm towards the engine faster than you can
let go.
Unintentional startup can result in entanglement,
traumatic amputation or laceration.
Broken bones, fractures, bruises or sprains could
result.
When starting engine, pull the starter cord slowly
until resistance is felt and then pull rapidly to

Parts Included
Your model 61302 gasoline replacement engine ships with the following parts
Spark Plug Socket 1 piece

Operation
Rev 61302-20090428 7
Assembly
This unit ships from our factory without oil.
It must be properly serviced with fuel and oil
before operation.
Add Engine Oil
CAUTION
DO NOT attempt to crank or start the engine
before it has been properly filled with the
recommended type and amount of oil. Damage
to the generator as a result of failure to follow
these instructions will void your warranty.
1. Place the engine on a flat, level surface.
2. Remove oil fill cap/dipstick to add oil.
3. Add 1.16 qt (1.1 L) of oil and replace oil
fill cap/dipstick.
4. Check engine oil level daily and add as
needed.
CAUTION
The engine is equipped with a low-oil-shutoff and
will stop when the oil level in the crankcase falls
below the threshold level.
NOTE
Check oil often during the break-in period. Refer
to the Maintenance section for recommended
service intervals.
Add Fuel
1. Use clean, fresh, regular unleaded fuel
with a minimum octane rating of 85.
2. DO NOT mix oil with fuel.
3. Clean the area around the fuel cap.
4. Remove the fuel cap
5. Slowly add fuel to the tank. DO NOT
overfill. Allow approximately ¼ inch of
space for fuel expansion.
6. Screw on the fuel cap and wipe away any
spilled fuel.
CAUTION
Use regular unleaded gasoline with a minimum
octane rating of 85.
DO NOT mix oil and gasoline.
Fill tank to approximately ¼” below the top of
the tank to allow for fuel expansion.
