GENERAL SAfETy RuLES
WARNING!
REAd ANd uNdERSTANd ALL INSTRucTIONS
failure to follow all instructions listed below may result in
electric shock, fire, and/or serious injury.
SAVE THESE INSTRucTIONS
WORk AREA
1.
2.
Keep your work area clean and well lit. Cluttered and dark areas invite acci-
dents.
Do not operate the Engine in explosive atmospheres, such as in the presence of
flammable liquids, gases, or dust. Gasoline engines create sparks which may ignite
the dust or fumes.
3.
Keep bystanders, children, and visitors away while operating a power tool. Distrac-
tions can cause you to lose control. Protect others in the work area from debris
such as chips and sparks. Provide barriers or shields as needed. Children should
never be allowed in the work area.
PERSONAL SAfETy
1.
2.
Stay alert. Watch what you are doing, and use common sense when operating a
power tool. Do not use a power tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating the Engine may
result in serious personal injury.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or
long hair can be caught in moving parts.
3.
4.
Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the Engine in unexpected situations.
Use safety equipment. Always wear eye protection. Dust mask, nonskid
safety shoes, hard hat, or hearing protection must be used for appropri-
ate conditions. Always wearANSI-approved safety goggles when using
or performing maintenance on this Engine.
TOOL uSE ANd cARE
1.
Do not force the Engine. Use the correct Engine for your application. The correct
Engine will do the job better and safer at the rate for which it is designed. Do not force
the Engine and do not use the Engine for a purpose for which it is not intended.

2.
3.
Do not use the Engine if the Engine’s Ignition Switch does not turn it on or off. Any
tool that cannot be controlled with the Ignition Switch is dangerous and must be
replaced.
Disconnect the Spark Plug Wire from the Engine before making any adjustments,
changing accessories, or storing the tool. Such preventive safety measures reduce
the risk of starting the tool accidentally. Always disconnect the Spark Plug Wire
before performing any inspection, maintenance, or cleaning procedures. Maintain
tools with care. Keep the Engine clean. Properly maintained engines are less
likely to malfunction and are easier to control. Do not use a damaged Engine. Tag
damaged engines “Do not use” until repaired.
4.
5.
Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tool’s operation. If damaged, have the Engine serviced
before using. Many accidents are caused by poorly maintained equipment.
Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when used
on another tool.
SERVIcE
1.
2.
Engine service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel could result in a risk of injury.
When servicing the Engine, use only identical replacement parts. Follow instruc-
tions in the “Inspection, Maintenance, And Cleaning” section of this manual. Use
of unauthorized parts or failure to follow maintenance instructions may create a risk
of injury and void applicable warranties.
SPEcIfIc SAfETy RuLES
1.
IMPORTANT! Your Warranty is voided if:
You do not put engine oil in the Engine’s crankcase prior to its first use. Before
each use, check the oil level. Never run the Engine with low or no engine oil. Run-
ning the Engine with low or no Engine oil will permanently damage the Engine.
2.
3.
4.
Maintain labels and nameplates on the Engine. These carry important information.
If unreadable or missing, contact Harbor Freight Tools for a replacement.
Maintain a safe working environment. Make sure there is adequate surrounding
workspace.
Avoid unintentional starting. Make sure you are prepared to begin work before
turning on the Engine. Learn and memorize how to shut off the Engine prior to

People with pacemakers should consult their physician(s) before use. Electro-
magnetic fields in close proximity to a heart pacemaker could cause pacemaker
interference or pacemaker failure. Caution is necessary when near the Engine’s
magneto or recoil starter.
Never leave the Engine unattended when it is running. Turn off the Engine before
leaving the work area.
7.
8.
9.
Always use the Engine on a flat, level, dry ground surface.
Make sure to keep hands and fingers away from all moving parts of the Engine.
Prior to installing the Engine onto a power equipment unit, make sure to read and
understand all instructions and safety precautions as outlined in the owner’s manual
for the power equipment.
TOXIc fuMES, fIRE, ANd EXPLOSION PREcAuTIONS
1.
This Engine is designed for outdoor use only. Do not operate the Engine in a closed
area or in a poorly ventilated area. When running, the Engine produces carbon
monoxide, a colorless, odorless, toxic gas that, when inhaled, can cause serious
personal injury or death. Whenever possible, use a carbon monoxide detector (not
included) to detect excessive carbon monoxide fumes in the work area and in the
surrounding area.
2.
Gasoline fuel and fumes are flammable, and potentially explosive. Use proper fuel
storage and handling procedures. Always have multiple ABC class fire extinguish-
ers nearby.
3.
4.
Keep the Engine and surrounding areas clean at all times.
When spills of fuel or oil occur, they must be cleaned up immediately. Dispose of
fluids and cleaning materials as per any local, state, or federal codes and regula-
tions. Store oil rags in a covered metal container.
5.
6.
Never store fuel or other flammable materials near the Engine.
Do not smoke, or allow sparks, flames, or other sources of ignition around the
Engine.
7.
Keep grounded conductive objects, such as tools, away from exposed, live electri-
cal parts and connections to avoid sparking or arcing. These events could ignite
fumes or vapors.
8.
Do not refill the Fuel Tank while the Engine is running or hot.
Do not operate the Engine with known leaks in the Engine’s fuel system.
Use only Engine manufacturer recommended oil and fuel.

3.
Located near the Crankshaft (16 - page 16) are different-sized mounting holes with
which to mount the Engine to your power equipment unit. (See figure A.)
Set the Engine side-by-side to the power equipment unit, and align the mounting
holes of the Engine with the mounting holes in the power equipment unit. NOTE:
There are different patterns of mounting holes available. Use the mounting holes
that best match the ones on the power equipment unit. (See figure A.)

the base of the engine. Then connect the REd (positive +) wire from the Starter
Motor to the positive (+) post on the battery. (See figure b.)
PRE-OPERATING INSTRucTIONS
1.
2.
3.
Make sure the Engine’s Crankcase is filled with approximately 37 ounces of
10-30W automotive oil. Also, make sure the Engine’s Fuel Tank is filled with
approximately 1-1/2 gallon of unleaded gasoline before attempting to start the
Engine. Failure to do so WILL damage the Engine and void the Warranty.
Before adding oil check to make sure the Drain Plug (2 - page 13) is tight. Unscrew
and remove the Dipstick (15 - page 14). Pour the required amount of oil into the
Crankcase Cover (4 - page 14). Then screw the Dipstick back into the Crankcase
Cover. (See figure c, next page.)
Unscrew and remove the Fuel Filler Cap (11 - page 19) from the Fuel Tank
(9 - page 19). Pour the required amount of unleaded gasoline (mid to high oc-
tane) into the Fuel Tank. Then screw the Fuel Filler Cap back onto the Fuel Tank.

off the Engine and disconnect the Spark Plug Wire from the Spark Plug to prevent
accidental starting. Then, allow the Engine to completely cool.
Before each use, inspect the general condition of the Engine. Check for loose bolts
and nuts, misalignment, binding of moving parts, loose or broken parts, damaged
fuel lines, and any other condition that may affect the safe operation of the Engine.
If abnormal noise or vibration occurs, turn off the Engine immediately and have the
problem corrected before further use. do not use damaged equipment.

or with compressed air. Do not use solvents. Do not allow water to enter the inter-
nal workings of the Engine.

6.
When storing, drain all fuel out of the Engine’s Fuel Tank. If this is not done, old fuel
in the Engine’s Fuel Tank and Carburetor may become contaminated and prevent the
Engine from starting until cleaned out. Do not drain oil. Always store the Engine in
a clean, dry, safe location out of reach of children and other unauthorized people.
