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. 23)
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

securely fi tted.
○ Check that nuts and screws are suffi ciently
tightened.
Weekly maintenance
○ Check the starter, especially the cord and return
spring.
○ Clean the exterior of the spark plug.
○ Remove it and check the electrode gap. Adjust it
to 0.024˝ (0.6 mm), or change the spark plug.
○ Check that the angle gear is fi lled with grease up
to 3/4.
○ Clean the air fi lter.
