Maintenance
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
•C h e c k the air cleaner every once week of use or more frequently if used under dusty conditions. A clogged air filter may increase fuel consumption while cutting down the engine power. Never operate the blower without the air filter or with a deformed filter element because unfiltered dusty air will quickly ruin the engine.
CLEANING AIR FILTER:
1.Unscrew 2 knob bolts and remove the air cleaner cover. Then remove a prefilter mounted inside the air cleaner cover.
2.Wash the prefilter in fresh, non flammable cleaning solution (ex. warm soapy water) and then dry.
(❈ Clean the air filter once in a week.) 3.Exchange the paper filter element with
new one in case it has been contaminated.
■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.
■SPARK PLUG
•The spark plug may gather carbon deposits on its firing end with reasonable use. Remove and inspect the spark plug every 25 hours and clean the electrodes as necessary with a wire brush. The spark gap should be adjusted to .025 in (0.6~0.7mm).
•Plug manufacturers recommend replacing the plug twice a year to avoid unexpected plug failure in a job.
REPLACEMENT PLUG IS A CHAMPION RCJ6Y.
IMPORTANT
•Note that using any spark plugs other than those designated may result in the engine failing to operate properly or in the engine becoming overheated and damaged.
•To install the spark plug, first turn the plug until it is finger tight, then tighten it a quarter turn more with a socket wrench.
