Make sure that the engine has stopped and is cool before performing any service to the machine. Con- tact with rotating blower fan or hot muffler may result in a personal injury.
■AIR CLEANER
Check the air cleaner every 25 hours of use or more fre- quently if used under dusty conditions. A clogged air filter may increase fuel consumption while cutting down the engine power. Never operate the mister without the air filter or with a deformed filter element because unfiltered dusty air may quickly ruin the engine.
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 re- tainer to disassemble it. Clean the components with gasoline.
