FUEL FILTER

When you mount or dismount the fuel filter, be
careful not to damage the rubber packing. A
damaged rubber packing or insufficient mounting of
the fuel filter will cause fuel to leak.

Check how heavily the fuel filter is clogged from the
fueling port of the fuel tank every 25 hours of use.
If the fuel filter is clogged with dust, empty the fuel tank,
take the fuel filter out, and clean it with a brush, etc.
If the clogging of the fuel filter cannot be removed or the
fuel filter is damaged, replace it with a new one.

Part No.: T1154-85100

If the fuel filter is clogged, the engine rotation speed
might not increase, or rotation fluctuations might occur.

(2) Fuel filter

SPARK PLUG

Do not touch the spark plug with bare hands
immediately after stopping the engine. The spark
plug is still so hot and might cause burns.

Take out the spark plug, check the electrodes, and if
contaminated, clean them with a wire brush, etc. every
25 hours of use.
When mounting the spark plug, screw the plug in with
your fingers, and then tighten it with the plug wrench
supplied as a standard accessory.
The spark gap should be adjusted to 0.6 to 0.7 mm.

AIR COOLING VENT

Do not put any waste into the intake air-cooling vent
while the machine is in operation. It might touch the
rotating part, causing danger.

Check the intake air-cooling vent and the cooling fin of
the cylinder, and remove any dirt attached thereto every
25 hours of use.

If any waste or dirt is jammed between the intake air-
cooling vent and the cylinder fin, the engine might
overheat, causing trouble.
