Air Filter

Dirty and clogged air filters reduce
engine power, increase fuel
consumption and make starting more
difficult.
The air filter should always be
cleaned when there is a noticeable
loss of engine power.
• Slacken off the screw (1).
• Swing the air filter cover (2) up
and remove it from the lugs.
• Remove felt filter element.

Pickup Body

The diaphragm pump draws fuel out of
the tank and into the carburetor via the
fuel hose. Any impurities mixed with
the fuel are retained by the pickup
body (filter). The fine pores of the filter
eventually become clogged with
minute particles of dirt. This restricts
the passage of fuel and results in fuel
starvation.
Important: In the event of trouble with
the fuel supply system, always check
the fuel tank and the pickup body first.
Clean the fuel tank if necessary.
Cleaning the fuel tank
• Unscrew the filler cap and drain the
tank.
- Pour a small amount of clean gasoline
into the tank.
- Close the tank and shake the saw
vigorously.
- Open the tank again and drain it.
Note: Dispose of old fuel at approved
disposal site.
