OPERATION FUELING AND REFUELING THE TRIMMER FUEL MIXTURE This product is powered by a 2-cycle engine and requires premixing gasoline and 2-cycle oil. Pre-mix unleaded gasoline and 2-cycle engine oil in a clean 1 gallon container approved for gasoline. Recommended fuel: This engine is certified to operate on unleaded gasoline intended for automotive use. Mix a high quality 2-cycle engine oil at 2.6 oz. per gallon (US). Do not use automotive oil or 2-cycle outboard oil.
OPERATION TO ADVANCE THE CUTTING LINE String advance is controlled by tapping the string head on grass while running engine at full throttle. 1. Run engine at full throttle. 2. Tap the spool retainer on ground to advance string. The string advances each time the spool retainer is tapped. Do not hold the spool retainer on the ground. NOTE: The line trimming cut-off blade on the grass deflector will cut the line to the correct length.
OPERATION OPERATING THE BRUSHCUTTER See Figures 19 - 20. Hold the brushcutter with the right hand on the rear handle and the left hand on the “J” Barrier Handle. Keep a firm grip with both hands while in operation. Brushcutter should be held at a comfortable position with the rear handle about hip height. Maintain your grip and balance on both feet. Position yourself so that you will not be drawn off balance by the kickback reaction of the cutting blade.

MAINTENANCE WARNING: Use only original manufacturer's replacement parts, accessories and attachments. Failure to do so can cause poor performance, possible injury and may void your warranty. You can often make adjustments and repairs described here. For other repairs, have the trimmer serviced by an authorized service dealer. SPOOL RETAINER Fig. 24 SPOOL REPLACEMENT NEW PREWOUND SPOOL See Figures 24 - 25. If replacing string only, refer to “String Replacement” later in this manual.
MAINTENANCE STRING REPLACEMENT See Figures 26 - 28. Use only monofilament string. Use original manufacturer's replacement string for best performance. String Diameter: CS30 - .080 in. (2.0 mm) SS30 - .095 in. (2.4 mm) BC30 - .095 in. (2.4 mm) 1. Stop the engine, disconnect the spark plug wire. Hold the string head and unscrew the spool retainer.

MAINTENANCE CLEANING THE EXHAUST PORT AND MUFFLER AIR FILTER COVER NOTE: Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port, muffler, and/or spark arrestor screen may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, you may need to remove these deposits to restore performance. We highly recommended that only qualified service technicians perform this service.
MAINTENANCE FUEL CAP WARNING: A leaking fuel cap is a fire hazard and must be replaced immediately. The fuel cap contains a non-serviceable filter and a check valve. A clogged fuel filter will cause poor engine performance. If performance improves when the fuel cap is loosened, check valve may be faulty or filter clogged. Replace fuel cap if required. SPARK PLUG This engine uses a Champion RCJ-6Y or NGK BPMR7A spark plug with 0,63 mm (.025 in.) electrode gap. Use an exact replacement and replace annually.
