The definitions below describe the level of severity for each signal word. Please read the manual and pay attention to these symbols. DANGER: Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING: Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury. CAUTION: Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury.

English • Moving parts such as the pulley, flywheel, and belt can cause serious injury if they come into contact with you or your clothing. WARNING: RISK OF Hot surfaces What can happen How to prevent it • Touching exposed metal • Never touch any exposed (muffler and other engine metal parts on engine during parts) can result in serious or immediately after operation. burns. The engine will remain hot for several minutes after operation.
What can happen • Unsafe operation of your engine could lead to serious injury or death to you or others. How to prevent it • Review and understand all instructions and warnings in this manual. • Become familiar with the opera tion and controls of the engine. • Keep operating area clear of all persons, pets, and obstacles. • Keep children away from the engine at all times. • Do not operate the engine when fatigued or under the influence of alcohol or drugs.

1. Remove fuel cap (A). 2. Add fresh, clean, regular unleaded gasoline with a minimum of 86 octane to the fuel tank (B). Do not fill above the shoulders on the debris screen (P) as shown. NOTE: The debris screen protects the engine from dirt and debris, only remove screen when cleaning. See Cleaning Debris Screen under Maintenance for instructions. Note: Do not mix oil with gasoline. 3. Replace the fuel cap on the tank. Turn the cap clockwise until it stops.
High Altitude Operating At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting. High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above 1,524 meters (5,000 feet), have your authorized service center perform a carburetor modification.
Warning: Hot surfaces. Risk of burn. Engine and surrounding parts are very hot, do not touch (see the Hot Surfaces identified in Figure 1). Allow engine to cool prior to servicing. A dirty air cleaner will restrict airflow to the carburetor. To prevent carburetor malfunction, service the air filter regularly. Service more frequently when operating the engine in extremely dusty areas. Warning: Using gasoline or flammable solvent to clean the filter element can cause a fire or explosion.
4. Remove oil fill/ CC CC dipstick to read oil level. If oil falls below top of pattern on dipstick, add oil. Note: Patterns (CC) may differ according to engine. NOTE: When filling the crankcase, allow the oil to flow very slowly. If the oil is added too quickly, it will overflow and appear to be full. 5. Replace dipstick and tighten securely. To change oil (fig.
English Spark Plug Note: The spark plug must be securely tightened. An improperly tightened spark plug can become very hot and could damage the engine. Never use spark plugs which have an improper heat range. Use only the recommended spark plugs or equivalent. Use recommended spark plugs, see specifications for correct spark plug. To ensure proper engine operation, the spark plug must be properly gapped and free of deposits. Warning: If the engine has been running, the muffler will be very hot.
Drain Carburetor Bowl (Fig. 1) 1. Place the fuel valve lever (J, if equipped) in the closed position. 2. Place an OSHA-approved container suitable for fuel under the carburetor bowl (M). NOTE: Using a funnel will allow the fuel to flow into the container with less spillage. 3. Remove the carburetor bowl drain (L). 4. Fuel will drain from carburetor bowl. 5. When drained, replace carburetor bowl drain.
