(JASO FC GRADE OIL or ISO EGC GRADE) • Do not use BIA or TCW (2-stroke watercooling type) mixed oil. ■ RECOMMENDED MIXING RATIO GASOLINE 50:OIL 1 50:1 MIXING CHART GASOLINE gal. 1 2 3 4 5 2-CYCLE OIL fl.oz 2.6 5.2 7.8 10.4 13 GASOLINE liter 2-CYCLE OIL ml 1 20 2 40 3 60 4 80 5 100 • Exhaust emission are controlled by the fundamental engine parameters and components(eq., carburation, ignition timing and port timing) without addition of any major hardware or the introduction of an inert material during combustion. • These engines are certified to operate on unleaded gasoline. • Make sure to use gasoline with a minimum octane number of 89 RON (USA/Canada: 87AL) • If you use a gasoline of a lower octane value than prescribed, there is a danger that the engine temperature may rise and an engine problem such as piston seizing may consequently occur. • Unleaded gasoline is recommended to reduce the contamination of the air for the sake of your health and the environment. • Poor quality gasolines or oils may damage sealing rings, fuel lines or fuel tank of the engine. ■ HOW TO MIX FUEL IMPORTANT Pay attention to agitation. 1. Measure out the quantities of gasoline and oil to be mixed. 2. Put some of the gasoline into a clean, approved fuel container. 3. Pour in all of the oil and agitate well. 4. Pour In the rest of gasoline and agitate 14 7. Fuel again for at least one minute. As some oils may be difficult to agitate depending on oil ingredients, sufficient agitation is necessary for the engine to last long. Be careful that, if the agitation is insufficient, there is an increased danger of early piston seizing due to abnormally lean mixture. 5. Put a clear indication on the outside of the container to avoid mixing up with gasoline or other containers. 6. Indicate the contents on outside of container for easy identification. ■ FUELING THE UNIT 1. Untwist and remove the fuel cap. Rest the cap on a dustless place. 2. Put fuel into the fuel tank to 80% of the full capacity. 3. Fasten the fuel cap securely and wipe up any fuel spillage around the unit. long period of time, clean the fuel tank after rendering it empty. Next, activate the engine and empty the carburetor of the composite fuel. 6. In the case of scrapping the used mixed oil container, scrap it only at an authorized repository site.

Never lean over the rotating cutting head. Rocks or other debris could be thrown into eyes and face and cause serious personal injury. 2. Keep the debris guard attached in place at all times when the unit is operated. TRIMMING GRASS AND WEEDS • Always remember that the TIP of the line does cutting. You will achieve better results by not crowding the line into the cutting area. Allow the unit to trim at its own pace. 1. Hold the unit so the head is off the ground and is tilted about 20 degrees toward the sweep direction. (OP6) 2. You can avoid thrown debris by sweeping from your right to the left. 17 8. Operation 3. Use a slow, deliberate action to cut heavy growth. The rate of cutting motion will depend on the material being cut. Heavy growth will require slower action than will light growth. 4. Never swing the unit so hard as you are in danger of losing your balance or control of the unit. 5. Try to control the cutting motion with the hip rather than placing the full workload on the arm and hands. 6. Take precautions to avoid wire, grass and dead, dry, long-stem weeds from wrapping around the head shaft. Such materials can stall the head and cause the clutch to slip, resulting in damage to the clutch system if repeated frequently. ADJUSTING THE LINE LENGTH • Your brushcutters is equipped with a semi- auto type nylon line head that allows the operator to advance the line without stopping the engine. When the line becomes short, lightly tap the head on the ground while running the engine at full throttle. • Each time the head is bumped, the line advance about 1 inch(25.4 mm). For better effect, tap the head on bear ground or hard soil. Avoid bumping in thick, tall grass as the engine may stall by overload. 18 9. Maintenance Maintenance, replacement, or repair of the emission control device and systems may be performed by any non-road engine repair establishment or individual. WARNING • Always be sure to stop the engine before inspecting the brushcutter for problems or performing maintenance. • Never alter the brushcutter or take the engine apart. • When replacing parts, always be sure to use only RedMax products or products which have been certified by RedMax for use with the RedMax brushcutter. • Things to check before using brushcutter. ■ REFILLING TRIMMING LINE 1 4 6 2 5 7 3.8m (12.5') Ø2.4mm 0.095In 3 7.6m (25') 19 9.

Maintenance ■ MUFFLER WARNING • Inspect periodically, the muffler for loose fasteners, any damage or corrosion. If any sign of exhaust leakage is found, do not use the brushcutter and have it repaired immediately. • Note that failing to do so may result in the engine catching on fire. MA5 (1) ■ 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. 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 is used in any forest covered, brush covered, or grass covered unimproved land. (MA5) (1) Spark arrester ■ INTAKE AIR COOLING VENT 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 brushcutter 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. Note that failing to do so could cause the muffler to become overheated, and that this in turn could cause the brushcutter 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 22 9. Maintenance hours of use for blockage, and remove any waste which has attached itself to the brushcutter. Note that it is necessary to remove the plug guard shown in Figure 20 in order to be able to view the upper part of the cylinder. IMPORTANT MA6 • 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. (MA6) (1) (1) Cylinder fin (2) Intake air cooling vent (back) (2) ■ 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 at the same time. (MA7) MA7 (1) (2) (1) Screwdriver (2) Muffler 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. 23 10.
