Pickup Body

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
– Remove the fuel tank 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.
