Spark plug (Fig. 24)
The spark plug condition is in
fl
uenced by:
○
An incorrect carburetor setting
○
Wrong fuel mixture (too much oil in the gasoline)
○
A dirty air
fi
lter
○
Hard running conditions (such as cold weather)
These factors cause deposits on the spark plug
electrodes, which may result in malfunction and
starting di
ffi
culties. If the engine is low on power,
di
ffi
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. Re-adjust
if necessary. The correct gap is 0.024
˝
(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.
Angle transmission (Fig. 25)
Check angle transmission or angle gear for
grease level about every 50 hours of operation by
removing the grease
fi
ller plug on the side of angle
transmission.
If no grease can be seen on the
fl
anks of the gears,
fi
ll the transmission with quality lithium based
multipurpose grease up to 3/4. Do not completely
fi
ll
the transmission.
