4. CONTROLS Engine switch The engine switch enables and disables the ignition system. The engine switch must be in the ON position for the engine to run and to start the blower. Turning the engine switch to the OFF position stops the blower and engine.
Priming pump Pressing the priming pump feeds the fuel from the fuel tank to the carburetor. This procedure is necessary for starting the engine. PRIMING PUMP Choke lever The choke lever opens and closes the choke valve in the carburetor. The CLOSED position enriches the fuel mixture for starting a cold engine.
Throttle lever The throttle lever controls the engine speed. Operate the throttle lever to run the blower. FAST THROTTLE LEVER SLOW Throttle cruise control lever The throttle cruise control lever holds the engine speed at high speed by squeezing the throttle lever when the engine is running and moving the throttle cruise control lever at the FAST position.
5. PRE-OPERATION CHECKS For safe and efficient blowing, always make a pre-operation inspection before operating. Perform a pre-operation inspection on firm, level surface with the engine stopped and spark plug cap removed from the spark plug. Check the engine oil level CAUTION: Running the engine with insufficient oil can cause serious engine damage.
Recommended oil: Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SE or later (or equivalent). Always check the API service label on the oil container to be sure it includes the letters SE or later (or equivalent).

1. Check the fuel level visually from outside of the fuel tank while keeping the fuel filler neck upright. 2. If the fuel level is low, refuel the fuel tank up to the level as specified. Remove the fuel tank cap gradually to release a pressured air in the fuel tank.
Gasoline containing alcohol If you decide to use a gasoline containing alcohol (gasohol), be sure its octane rating is at least as high as that recommended by Honda. There are two types of “gasohol”: one containing ethanol, and the other containing methanol.
Check the air cleaner elements CAUTION: Never run the engine without air cleaner; rapid engine wear will result. 1. Move the choke lever to the full closed position. 2. Open the air cleaner cover by pushing the right side tabs of the air cleaner cover.
