any service to the blower. Contact with rotating blower fan or hot
muffler may result in a personal injury.

much of oil, so that the element becomes dry after a few hours.

heavier than it was dried.

body.
Never forget to attach the screen properly. If the screen is not attached, the
cleaner will not seal properly and the dusts come into the cylinder.

A clogged fuel filter may cause poor acceleration of the engine. Check
periodically to see if the filter is clogged with dirt. The filter can be taken out of
the fueling port using a small wire hook. Disconnect the filter assembly from
the fuel pipe and unhook the retainer to disassemble it. Clean the components
with gasoline.
