4. When all the engine oil has been drained, place
the unit horizontally on a clean, fl at surface.
5. Fill the oil tank with engine oil up to the mouth of
the oil tank opening. (Fig. 7)
6. Tighten the oil cap securely by hand.
NOTE
○ Do not dispose of waste engine oil with garbage
or into the ground.
Dispose of the oil according to the specifi ed
method in your area.
If you are unsure, contact the retailer where the
oil was purchased.
○ Fill the oil tank with the specifi ed amount of
engine oil.
Too much or too little engine oil may result in
engine breakdown.
○ Engine oil deteriorates naturally even if unused.
Change the engine oil regularly.
Air fi lter (Fig. 18)
The air fi lter must be cleaned from dust and dirt in
order to avoid:
○ Carburetor malfunctions.
○ Starting problems.
○ Engine power reduction.
○ Unnecessary wear on the engine parts.
○ Abnormal fuel consumption.
Clean the air fi lter daily or more often if working in
exceptionally dusty areas.
Cleaning the air fi lter
Remove the air fi lter cover and the fi lter (14). Rinse
it in gasoline. Check that the fi lter is dry before
reassembly. An air fi lter that has been used for some
time cannot be cleaned completely. Therefore,
it must regularly be replaced with a new one. A
damaged fi lter must always be replaced.
Fuel fi lter (Fig. 19)
Remove the fuel fi lter (15) from the fuel tank, and
replace it if it is dirty.

NOTE
A blocked fuel fi lter (15) can prevent the supply of
fuel and cause a rotation malfunction of the engine.

Spark plug (Fig. 20)
.024˝
(0.6 mm)
The spark plug condition is infl uenced by:
○ An incorrect carburetor setting.
○ A dirty air fi lter.
○ Hard running conditions (such as cold weather).
○ Too much engine oil
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting diffi culties. If the engine is low on power,
diffi cult to start or runs poorly at idling speed, always
check the spark plug fi rst. If the spark plug is dirty,
clean it and check the electrode gap. Readjust if
necessary. The correct gap is .024˝ (0.6 mm). The
spark plug should be replaced after about 100
operation hours or earlier if the electrodes are badly
eroded.
NOTE
In some areas, local law requires using a resistor
spark plug to suppress ignition signals. If this
machine was originally equipped with resistor
spark plug, use same type of spark plug for
replacement.
