Air filter (Fig. 3-2)
The air filter 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 filter daily or more often if working
in exceptionally dusty areas.
Cleaning the air filter
Remove the air filter cover and the filter. Rinse
it in warm soap suds. Check that the filter is dry
before reassembly. An air filter that has been
used for some time cannot be cleaned com-
pletely. Therefore. it must regularly be replaced
by a new one. A damaged filter must always be
replaced.
Spark plug (Fig. 3-3)
The spark plug condition is influenced by:
An incorrect carburetor setting.
Wrong fuel mixture (too much oil in the
gasoline)
A dirty air filter.
Hard running conditions (such as cold
weather).

These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting difficulties. If the engine is low on
power, difficult to start or runs poorly at idling
speed, always check the spark plug first. If the
spark plug is dirty, clean it and check the
electrode gap. Readjust if necessary. The
correct gap is 0.6 mm (.024"). 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.

Transmission (Fig. 3-4)
Check transmission or gear for grease level
about every 50 hours of operation by removing
the grease filler plug on the side of
transmission.
If no grease can be seen on the flanks of the
gears, fill the transmission with a quality lithium
based multipurpose grease up to 3/4.
Do not completely fill the transmission.
