BCZ3050S/T/SW 9. Maintenance ■ MUFFLER MA5 MA6 WARNING • Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, stop using the machine and have it repaired immediately. • Note that failing to do so may result in the engine catching on fire. ■ SPARK ARRESTER • The muffler is equipped with a spark arrester to prevent red hot carbon from flying out of the exhaust outlet. MA7 (1) Periodically inspect and clean as necessary with a wire brush. In the State of California it is required by law (Section 4442 of the California Public Resources Code) to equip a spark arrester when a gas powered tool (2) is used in any forest covered, brush (1) covered, or grass covered unimproved land. (MA5) (1) spark arrester ■ GEAR CASE (MA6) • The reduction gears are lubricated by multipurpose, lithium-based grease in the gear case. Supply new grease every 25 hours of use or more often depending on the job condition. • Remove the side bolt in gear case opposite of grease nipple before installing new grease to arrange for old grease to exit. MA8 ■ INTAKE AIR COOLING VENT US-16 WARNING • Never touch the cylinder, muffler, or spark plugs with your bare hands immediately after stopping the engine. The engine can become very hot when in operation, and doing so could result in severe burns. • When checking the machine to make sure that it is okay before using it, check the area around the muffler and remove any wood chips or leaves which have attached themselves to the brushcutter. Failing to do so could cause the muffler to become overheated, and 10. Storage 11. Disposal that this in turn could cause the engine to catch on fire. Always make sure that the muffler is clean and free of wood chips, leaves, and other waste before use. • Check the intake air cooling vent and the area around the cylinder cooling fins after every 25 hours of use for blockage, and remove any waste which has attached itself to the brushcutter. Note that it is necessary to remove the engine cover shown in (MA7) in order to be able to view the upper part of the cylinder. IMPORTANT • If waste gets stuck and causes blockage around the intake air cooling vent or between the cylinder fins, it may cause the engine to overheat, and that in turn may cause mechanical failure on the part of the brushcutter. (MA7) (1) cylinder (2) intake air cooling vent (back) ■ PROCEDURES TO BE PERFORMED AFTER EVERY 100 HOURS OF USE 1. Remove the muffler, insert a screwdriver into the vent, and wipe away any carbon buildup. Wipe away any carbon buildup on the muffler exhaust vent and cylinder exhaust port at the same time. 2. Tighten all screws, bolts, and fittings. 3. Check to see if any oil or grease has worked its way in between the clutch lining and drum, and if it has wipe it away using oil-free, lead-free gasoline. • Aged fuel is one of major causes of engine starting failure. Before storing the unit, empty the fuel tank and run the engine until it uses all the fuel left in the fuel line and the carburetor. Store the unit indoor taking necessary measures for rust prevention. • When disposing your machine, fuel or oil for the machine, be sure to allow your local regulations.
