Parts Location & Specifications Assembly ■ BLOWER PIPE • Align groove in blower pipe with projection on blower housing (or another blower pipe) and slide the pipe onto the blower housing (or another blower pipe). Rotate the pipe clockwise to lock it into place.
9 Fuel ■ RECOMMENDED MIXING RATIO GASOLINE 50:OIL 1 • 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.
10 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.
11 ■ RESTARTING ENGINE WHILE ENGINE IS HOT 1. When restarting the engine immediately after stopping it, leave the choke open. 2. If the engine won't start after several attempts, close the choke and repeat pulling the rope or remove the spark plug and dry it.
12 ■ FUEL FILTER •A clogged fuel filter may cause poor acceleration of the engine. Check periodically to see if the filter is clogged with dirt. The filter can be taken out of the fueling port using a small wire hook. Disconnect the filter assembly from the fuel pipe and unhook the retainer to disassemble it.
the muffler may get loose during operation which may result in 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.
14 Storage BEFORE STORING THE BLOWER: 1. Drain a fuel tank and push the primer bulb until it becomes empty of fuel. 2. Remove the spark plug and drop a spoonful of 2-cycle oil into the cylider. Crank the engine several time and install the spark plug.
