SAFETY PRECAUTIONS
In order to ensure safety operator, please carefully read and follow the instructions
while operating.
Never operate the air compressor without the belt guard. Failing to do so can lead to
serious injuries as objects may get caught in the belt.
Keep visitors away and NEVER allow children in the work area.
Operate the compressor ONLY outdoors. Never run the compressor indoors.The
engine gives off poisonous carbon monoxide, an odorless, and colorless gas. Inhaling
carbon monoxide will cause nausea, fainting or death. Also, keep the air compressor at
least 20 feet away from flammable material and allow for adequate ventilation.
Wear safety glasses and wear hearing protection when operating the unit.
Always inspect the unit for damage before operating the unit. Inspect the engine for oil
leaks or possible deterioration.
Check all fasteners for proper tightness at frequent intervals.
Do not wear loose clothing or jewelry.It may get caught in the moving mechanical parts
of the air compressor. Also keep all fingers and other body parts away from the
compressor as it may get caught in the moving mechanical parts.
PREVENTION FROM ACCIDENTAL BURNS
Never touch the muffler and its cover when the engine is running. Never touch the
muffler and cover after the engine has been used, as the muffler remains hot for a good
period of time.
The discharge tube from the air compressor to the tank gets hot during operation, do not
touch the tube during operation.
ENGINE SAFETY PRECAUTIONS
Do not touch hot surfaces. Allow equipment to fully cool down before touching.
After the air compressor has been run, the engine produces heat. The temperatures of the
muffler and nearby areas can reach or exceed 160
0
F. Severe burns will occur on contact
with skin.
Do not modify the air compressor in any way. The air compressor supplies the rated
pressure and rated airflow at its governed speed.

7
AIR TANK SAFETY
Do not attempt to adjust the safety valve. Also, never attempt to repair or modify a tank.
The fabrication involved in modifications of the tank will weaken the tank. Always
replace worn, cracked, or damaged tanks.
Operate the air compressor on level surfaces only. Inclined surfaces reduce the effective
lubrication of the engine.
Do not expose the air compressor to excessive moisture, dust, dirt, or corrosive vapors.
PREPARATION BEFORE OPERATION
Before starting the air compressor, verify the following conditions.
AIR COMPRESSOR OIL
xVerify that the air compressor head is filled with 10W-30 viscosity oil. Running
the air compressor without oil will cause severe damage to the air compressor
head.The air compressor is not shipped with oil.
ENGINE OIL
xFill the engine with SAE 10W-30 engine oil for general use or follow the table
below.
xMake sure the air compressor is on a level surface and make sure the oil dipstick
is on tight.The engine is not shipped with oil.
FUEL
x Add gasoline and never fill the fuel tank indoors. Also, be sure the fuel tank cap is
on tight after filling.
x DO NOT overfill the fuel tank. Always allow room for fuel expansion.
x Never fill the fuel tank when the engine is running or hot. Allow the unit to cool
for 10 minutes before refueling. DO NOT light a cigarette or smoke when
filling the fuel tank.

8
AIR CLEANER
x Remove the wing nut holding down the air cleaner cover.
x Remove the air cleaner cover and air filter.
x Check the air cleaner element to
be sure they are clean and in
good condition.
x If the air filter is dirty, remove
and clean the element.
x Wash in solvent
x Squeeze
x Soak oil
x
x
Squeeze dry
Do not wet the paper filter if supplied
x Reinstall the air cleaner element
and secure the cover by setting
the cover spring.
PRESSURE CONTROL VALVE
x Put the control valve is in the up
position before starting the air
compressor.

9
STARTING THE AIR
COMPRESSOR
Turn the fuel valve to the ON position.
Move the choke lever to the CLOSED
position.
Note: If the engine is warm or the air
temperature is high, do not use the choke
Move the throttle control lever slightly to
the left.
Turn the engine switch to the ON position.
With the recoil starter, pull the handle fast.
Gradually move the choke lever to the
OPEN position when the engine warms
up.
Adjust the throttle control lever until
you reach the desired speed.

10
STOPPING THE ENGINE
In the event of an emergency, turning the engine switch to the “Off” position can stop the
engine. Under regular conditions, follow these procedures
x Shift the throttle lever fully to the right.
x Turn the engine switch to the off position.
x Turn the fuel valve to the off position.
Note: When operating your engine in high altitudes, the fuel air mixture may be affected by the high
altitude condition. In high altitudes, performance is decreased and fuel consumption is increased.
Please consult with your local dealer for details on adjusting your engine high altitude conditions.
Pull the recoil handle slowly until pressure is felt by your hand, this means the piston is
on the compression stroke; where the intake and exhaust valves are closed and then let
the handle recoil back into the engine. This natural position will prevent rust from
occurring when the engine is being stored for long periods of time.
MAINTENANCE
AIR COMPRESSOR
Check the oil level of both the engine and air compressor head daily before operating the
air compressor.
ENGINE OIL CHANGE
Engine oil is a critical factor in determining the life of your engine. Change the engine
oil on time. Change the engine oil more frequently if the engine is used in dusty areas.
Changing the oil while the engine is still warm will yield best results for the engine.
When the oil is still warm, you get rapid and complete draining of the oil.
Oil change procedures
1. Remove the oil filler cap and drain plug to drain the oil
2. Install the drain plug, and tighten it securely.
3. Refill with the recommended oil and check the oil level.
4. Install the oil filler cap.
The engine oil capacity is .60 liters or .16 gallons.

11
Note: Do not touch motor oil for long periods of time. Used motor oil can cause skin
cancer if it comes in contact with the skin for prolonged periods of time. Getting cancer
from used motor oil is unlikely unless you handle used motor oil on a daily basis. To be
safe always wash your hands thoroughly with soap and water as soon as possible after
handling used oil.
Below is a routine maintenance schedule.
AIR FILTER SERVICE
A dirty or clogged air filter will prevent air from flowing freely into the carburetor
assembly. Always keep the air filter clean or replace if necessary. Also, if the air filter is
dirty or clogged, the performance of the engine goes down. If operating the engine in a
dusty area, service the air filter more frequently as dust particles will clog the filter at a
faster rate. Never run the engine without an air filter, dust particles may get into the
intake system and damage the engine. Rapid engine wear will occur if the engine is run
without the air filter.
Do not wash the air filter if it is the paper type. Also, never use gasoline to wash air filter
elements because gasoline is highly flammable and dangerous. A fire or explosion could
occur.
Instructions on changing the air filter.
x Take the wing nut off and remove the air filter cover. Remove the elements
and separate them. Check the elements for tears and holes. If holes or tears
are present, replace the air filter elements.
x The foam element can be washed. Warm water and household detergent will
work fine for washing the foam filter element. After washing, rinse it
thoroughly with water and allow the element to dry. Soak the element in

12
clean engine oil and squeeze the oil out. If there is too much oil left in foam
element, the engine will smoke during startup.
x Tap lightly several times on a hard surface to remove excess dirt from the
paper filter. Never brush on the paper element as this just forces more dirt
into the paper element. Use compressed air to blow from the inside out to
remove the excess dirt.
DRIVEBELT
Belts will stretch in normal use. A properly adjusted belt will deflect ½ inch with a 5
pound force. To adjust the belt tension, follow the procedures below.
x Remove the belt guard.
x Loosen the four fasteners holding the engine to the base-plate.
x Shift the engine in the proper direction so that the desired tension is achieved.
x Align the belt and pulleys before tightening down the engine.
CLEANING THE AIR COMPRESSOR
Air compressor maintenance consists of keeping the unit clean and dry. Be sure to store
the unit in a clean and dry environment, where it will not be exposed to excessive dust,
dirt, moisture or any corrosive vapors. Cooling slots should always be clean and free
from clogs.
Note: Do not use a garden hose to clean the air compressor. Water can enter the fuel and
intake system and cause severe damage.
x To clean the air compressor, use a damp cloth to wipe the exterior surfaces.
x Use a soft bristle brush to loosen caked on dirt of oil.
x Use a vacuum cleaner to pick up loose dirt and debris.
x Compressed air (not to exceed 25 psi) may be used to blow away dirt.
SEDIMENT CUP CLEANING
Turn the fuel valve off and remove the sediment cup with the O-ring. Wash them
thoroughly in non-flammable solvent. Dry them thoroughly and reinstall them tightly.
Turn the fuel valve ON and look for leaks.
Note: Try not to spill fuel, if fuel is spilled, clean the area first before starting the engine.
The engine may create a spark when started, so if there is fuel around, it may ignite the
fuel causing a serious fire or explosion.
SPARK PLUG SERVICE
x Remove the wire from the spark plug.
x Use a deep socket or spark plug socket to remove the spark plug.

13
x Check for mechanical damage and or carbon buildup.
x If the spark plug is fouled, replace spark plug with new one.
xCheck the spark plug gap,7mm or .028.
Notes: Make sure the replacement spark plug is in the correct heat range. An incorrect
heat range spark plug can damage your engine. Also, never touch the muffler during or
after the engine has been run.
x Make sure the spark plug washer is in good condition or brand-new.
x Threadthe spark plug in by hand first before using a tool. This will prevent
stripping the threads on the cylinder head assembly and the spark plug.
x After the spark plug has seated, tighten the spark plug with a spark plug wrench to
compress the washer. Do not over tighten.
Note: For new spark plugs, tighten an extra ½ turn after the spark plugs seats to
compress the washer. If installing a used spark plug; tighten 1/8 – ½ turn. The spark
plug must be securely tightened, or the spark plug can become very hot and damage the
engine.
CARBURETOR ADJUSTME
Please set an authorized dealer for adjustments.
PUTTING THE AIR COMPRESSOR IN STORAGE OR TRANSPORTING
Please follow these instructions before storing your engine.
x Clean the storage area.
x Drain the fuel into a suitable container.
x Remove the sediment cup and clean thoroughly.
x Replace the sediment cup and tighten securely.
x Drain the fuel from the carburetor by loosening the drain screw. Drain the fuel
into a suitable container.

14
Note: Do not smoke near gasoline. Also do not allow flames or sparks near gasoline
because gasoline is extremely flammable.
x Change the engine oil while engine is still warm.
x Take the spark plug out and put some oil into the combustion chamber. Then use
the recoil starter and crank the engine a few times to mix the oil around in the
chamber. Put the spark plug back on being careful not to strip the threads.
x Pull the starter rope until resistance is felt. This is when the intake and exhaust
valves are closed and the piston is on the compression stroke.
