CAUTION! 1.Shutting Engine Off Before shutting the engine off, allow it to idle for a short while. • Never stop the engine by closing the choke. • Never stop the engine during operation while running above idle speed. 2.Transporting and Storage • Shut off the engine and allow it to cool before transporting or storing the unit. • Do not put the unit on dry grass or near any flammable object unless the engine is cold or cooled down.
FUEL; MIXING GASOLINE AND OIL CAUTION! If Maruyama brand oil is not used, never use a mixing ratio less than 50:1 regardless of the oil package mixing instructions. Ratios less the 50:1, (for example, 60:1, 80:1, 100:1), reduce the amount of lubrication to the internal moving parts of the engine and can cause damage. Gasoline 50:1 2-Cycle Oil 5 Litres 100 ml 10 Litres 200 ml 20 Litres 400 ml MIXING INSTRUCTIONS: Always mix fuel and oil in a clean container approved for gasoline.
OPERATING INSTRUCTIONS STARTING PROCEDURE STEP #2) Move the "CHOKE LEVER" fully up ward to the closed position. If the engine is already warm, only a partial or open (no choke) choke setting may be required. STEP #1) Pump the "PRIMER BULB" under of the carburetor until fuel can be seen flowing through the "FUEL-RETURN LINE". CLOSE PRIMER BULB CHOKE LEVER OPEN FUEL RETURN LINE Standard STEP #3) Set the throttle lever at 1/2 speed.
STEP #4) Warming up the engine. When the engine has started, slowly move the "CHOKE LEVER" fully upward to the open position. Allow the engine to "WARM-UP" at less than 1/2 speed. OPEN If a MARUYAMA engine fails to start after following the above procedures, contact an authorized MARUYAMA dealer. BLOWER OPERATION When the engine has warmed-up, the power blower can be positioned on the back of the operator.
REGULAR MAINTENANCE Before each use, the power blower should be inspected for proper assembly and fitness of all components. All fasteners should be checked for correct tightness. Always inspect for fuel leaks. WARNING Do not attempt to start or operate a power blower that indicates a fuel leak. AIR FILTER AIR FILTER (PAPER) The air filter should be inspected each time the power blower is used (or more often with extreme conditions).
COOLING FINS Free passage of air flow through the cylinder cooling fins is required to prevent poor engine performance and shortened engine life. Regularly check and clean all debris from the cooling fins by removing the engine cover (see sketch). ENGINE COVER COOLING FINS MUFFLER AND EXHAUST PORTS The muffler should be removed and serviced after each fifty (50) hours of use. At the same time, the exhaust ports should be cleaned and inspected.
EMISSION CONTROL INFORMATION FUEL INFORMATION THIS ENGINE IS CERTIFIED TO OPERATE ON UNLEADED REGULAR GRADE GASOLINE ONLY. A minimum of 87 octane of the antiknock index is recommended. The antiknock index is posted on service station pumps in the U.S.A.. EMISSION CONTROL INFORMATION To protect the environment in which we all live, Kawasaki has incorporated an exhaust emission control system.
FUEL RECOMMENDATIONS FUEL The Kawasaki TK series 2-stroke engines require a gasoline-oil mixture. Use only clean, fresh, unleaded regular grade gasoline. Octane Rating The octane rating of a gasoline is a measure of its resistance to "knocking". Use of a minimum of 87 octane of the antiknock index is recommended. The antiknock index is posted on service station pumps. NOTE: • If "knocking or pinging" occurs, use a different brand of gasoline or higher octane rating.
ADJUSTMENT IDLING SPEED ADJUSTMENT 1. Idle speed is the only available adjustment. 2. Do not tamper with the carburetor setting to increase the maximum engine speed. 3. If adjustment is needed, have it performed by your authorized MARUYAMA service dealer. Carburetor adjustments are made at the factory and are not adjustable without disassembling the carburetor.
