Check and clean the filter element in warm, soapy water as required. Dry completely before installing. If the element is broken or shrunk, replace with a new one. IMPORTANT • Note that using any spark plug other than those designated may result in the engine failing to operate properly or in the engine becoming overheated and G damaged. B •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. 87 ~ 104 in-lbs TIGHTENING TORQUE: (9.8 ~ 11.8 N.m.) MUFFLER WARNING Air Filter FUEL FILTER • When the engine runs short of fuel supply, check the fuel cap and the fuel filter for blockage.s Fuel filter SPARK PLUG • Starting failure and mis-firing are often caused by a fouled spark plug. Clean the spark plug and check that the plug gap is in the correct range. For a replacement plug, use the correct type specified by ZENOAH. 0.6 to 0.7 mm • REPLACEMENT PLUG IS A NGK CMR7A. • 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. Periodically inspect and clean as necessary with a wire brush. Spark arrester GEARCASE AND CUTTERCASE • Periodically refill the case with grease (every 25 hours). • Use only lithium based greases. Grease: approx. 10cc Screw Plane washer Air purge Grease: approx. 5cc Bolt GB-15 SGCZ2600DL/SGCZ2600DW 9. Maintenance INTAKE AIR COOLING VENT PROCEDURES TO BE PERFORMED AFTER EVERY 100 HOURS OF USE 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 machine. Failing to do so could cause the muffler to become overheated, and 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 machine. Note that it is necessary to remove the engine cover shown in (A) 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 machine. Cylinder (A) Intake air cooling vent 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. 10. Storage • 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. • Oil the blades. 11. Disposal When disposing your machine, fuel or oil for the machine, be sure to allow your local regulations.
