BLOWER OPERATION
When the engine has warmed-up, the Backpack Blower can be positioned on the back of the operator.
When the Backpack Blower is positioned and ready for operation, adjust the throttle to a speed required to accomplish the task.
• Never operate Backpack Blower when you are fatigued.
• Never operate Backpack Blower without proper guards or other protective safety devices in place.
To prevent overheating and engine seizure, combustion heat is reduced by air entering the intake grille of the fan housing and is
pushed by the blower fan through an opening in the fan housing over the cylinder fin area. The grille and cylinder fins must be kept
clean of grass, dust, and any debris. Engine failure due to lack normal maintenance is not covered by warranty.

cooling before stopping. To stop the engine, press and hold the
