Fuel fi lter (Fig. 25)
Check the fuel fi lter occasionally for clogging as
insuffi cient fuel fl ow could aff ect engine speed.
Drain all fuel from fuel tank and pull fuel fi lter (30)
from tank. Rinse it in warm water with detergent.
Rinse thoroughly until all traces of detergent are
eliminated. Squeeze, away excess water and allow
element to air dry.
NOTE
If the fuel fi lter (30) is hard due to excessive dirt
buildup, replace it.

Spark plug (Fig. 26)
The spark plug condition is infl 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 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. 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.
Flexible drive shaft (Fig. 27)
(curved drive shaft tube model)
Flexible drive shaft should be removed and
lubricated with good quality lithium grease every
20 hours. To remove the fl exible shaft, fi rst remove
screw (31), loosen bolt (32) and remove the cutter
case then pull the shaft out of the drive shaft tube.
Clean the shaft off and apply a generous coat of
lithium grease to it and insert if back into the drive
shaft tube, turn it unit it drops into place then install
the cutter case, install & tighten screw (31) and bolt
(32).
31
Gear case (Fig. 28)
Check gear case or angle gear for grease level
about every 50 hours of operation by removing the
grease fi ller plug on the side of gear case.
If no grease can be seen on the fl anks of the
gears, fi ll the gear case with quality lithium based
multipurpose grease up to 3/4. Do not completely fi ll
the gear case.
