11.4 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.
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.
Observe safety precautions – b 2.
– 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.
Dispose of fuel properly.
Pickup body
– Unscrew the fuel filler cap and
remove it together with the cap
retainer, if fitted.
