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.

TROUBLESHOOTING

Symptom

Probable cause

Corrective Action

Low discharge
pressure.

1. Air demand exceeds

pump capacity.

2. Leaking air

3. Restricted air intake
4. Blown gaskets
5. Leaking or damaged

valves.

1. Decrease air demand or use a larger

capacity air compressor

2. Listen for high pitched escaping air.

Apply soap solution to all fittings and
connections. Bubbles will appear at
points of leakage. Tighten or replace
leaking fittings or connections.

3. Clean air filter element
4. Replace faulty gaskets.
5. Remove head and inspect for valve

breakage, misaligned valves, damaged
valve seats, etc. Replace defective
parts and reassemble.

Pump
overheating and
damaging air
filter.

1. Insulating gasket

between filter and
head is missing.

2. Broken valves blown

gasket.

1. Install gasket.

2. Replace valves or install new gasket.

Excessive noise
or abnormal
noise

1. Loose motor or loose

pulley.

2. Low oil in crankcase

3. Worn connecting

rods

4. Worn piston pin

5. Piston hitting valve

plate.

1. Tighten engine mount bolts and pulley

setscrews.

2. Refill oil to the proper level. Also, if

always low, check for possible damage
to bearings or oil leaks

3. Replace connecting rod. Maintain oil

level and change oil more frequently.

4. Remove old piston pin, measure and

verify specifications are within limits.
If not, replace piston pin and replace oil
more frequently.

5. Remove the compressor head and valve

plate for carbon deposits or other
foreign objects. Replace the head and
valve plate and use a new gasket.
