WARNING
Make sure that the engine has stopped and is cool before performing any service to the blower. Contact with rotating blower fan or hot muffler may result in a personal injury.
AIR CLEANER
-Check the air cleaner before use.
A clogged air filter may increase fuel consumption while cutting down the engine power.
-Never operate the blower without an air filter or with a deformed or broken filter element because unfiltered dusty air will quickly ruin the engine.
CLEANING AIR FILTER:
1. Unscrew the 2 knobs and remove the air cleaner cover.

-Do not apply 4 cycle motor oil as they may damage element.
-Do not use mixture gasoline.This type of gasoline does not contain much of oil, so that the element becomes dry after a few hours.
-Soak the filter element into filter oil.
-Squeeze the element to remove excess oil so that it weighs 2 to 3 times heavier than it was dried.
4.Reinstall the element into the packing,set the packing into the air cleaner 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.
5.Reinstall the air cleaner cover and screw the 2 knobs.
FUEL FILTER
-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.
