OPERATION FUELING AND REFUELING THE TRIMMER FUEL MIXTURE This product is powered by a 2-cycle engine and requires pre-mixing 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 and 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 trigger 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. SPOOL RETAINER You can often make adjustments and repairs described here. For other repairs, have the trimmer serviced by an authorized service dealer. SPOOL REPLACEMENT Fig. 24 SPRING NEW PREWOUND SPOOL See Figures 24 and 25. If replacing string only, refer to “String Replacement” later in this manual.
MAINTENANCE STRING REPLACEMENT See Figures 26, 27, and 28. Use only monofilament string. Use original manufacturer's replacement string for best performance. String Diameter: ZR30000 - .080 in. (2.0 mm) ZR30002 - .095 in. (2.4 mm) ZR30004 - .095 in. (2.4 mm) 1. Stop the engine, disconnect the spark plug wire. Hold the string head and unscrew the spool retainer. To remove the spool retainer: Turn the spool retainer counterclockwise for models ZR30000.
MAINTENANCE CLEANING THE EXHAUST PORT AND MUFFLER LATCH Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port and muffler may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, a qualified service technician will need to remove these deposits to restore performance.
MAINTENANCE FUEL CAP STORAGE (1 MONTH OR LONGER) 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. 1. Drain all fuel from tank into a container approved for gasoline. Run engine until it stops. 2.
