Pre-mix unleaded gasoline and 2-cycle engine oil in a clean container approved for gasoline. This engine is certified to operate on unleaded gasoline intended for automotive use with an octane rating of 87 ([R + M] / 2) or higher. Do not use any type of pre-mixed gasoline/oil from fuel service stations, this includes the pre-mixed gasoline/oil intended for use in mopeds, motorcycles, etc. NOTE: It is normal for smoke to be emitted from a new engine during and after first use. WARNING: Always shut off engine before fueling. Move at least 9 m (30 ft. ) from refueling site before starting engine.

Trimmer should be held at a comfortable position with the trigger handle about hip height. This will prevent grass from wrapping around the shaft housing and string head which may cause damage from overheating. If grass becomes wrapped around the string head, stop the engine, disconnect the spark plug wire, and remove the grass. Prolonged cutting at partial throttle will result in oil dripping from the muffler. FILLING THE TANK 1. Loosen fuel cap slowly to release pressure and to keep fuel from escaping around the cap. Keep the trimmer tilted toward the area being cut; this is the best cutting area. Use the tip of string to do the cutting; do not force string head into uncut grass. Tree bark, wood moldings, siding, and fence posts can easily be damaged by the string. DANGEROUS CUTTING AREA Fig. 9 ADVANCING THE STRING ADVANCING STRING USING THE EZ LINETM TAP ADVANCE SYSTEM String advance is controlled by tapping string head on grass while running engine at full throttle. NOTE: If the string is worn too short you may not be able to advance the string by tapping it on the ground. [. . . ] If engine does not start, move choke lever to "COLD START" and follow normal starting instructions in "STARTING AND STOPPING" section. If engine still fails to start, repeat procedure with a new spark plug. Lever will not go into the "COLD START" position: Engine starts but will not accelerate: Throttle trigger is depressed. Release throttle trigger. If "L" low needle can not be turned counterclockwise, do not force plastic limiter caps. [. . . ]
