9.1
Using fuel additives
The use of fuel additives will inhibit corrosion and minimize the formation of gum deposits.
Using a fuel additive can keep fuel from forming harmful deposits in the carburettor for up to
six months. Add 23 ml of fuel additive per gallon of fuel according to the instructions on the
fuel additive container. NEVER add fuel additives directly to the unit’s fuel tank.
Warning: remove fuel cap slowly to avoid injury from fuel spray. Never
operate the unit without the fuel cap securely in place.
Warning: when the engine stops, do not touch the muffler or spark plug
immediately in order to avoid any skin from burning.
