ENGINE
FUEL SYSTEM
IMPORTANT: IT IS IMPORTANT TO PREVENT GUM DEPOSITS
FROM FORMING IN ESSENTIAL FUEL SYSTEM PARTS
SUCH AS CARBURETOR, FUEL FILTER, FUEL HOSE, OR
TANK DURING STORAGE. ALCOHOL BLENDED FUELS
(CALLED GASOHOL OR USING ETHANOL OR METHANOL)
CAN ATTRACT MOISTURE WHICH LEADS TO SEPARATION
AND FORMATION OF ACIDS DURING STORAGE. ACIDIC GAS
CAN DAMAGE THE FUEL SYSTEM OF AN ENGINE WHILE IN
STORAGE.
• Empty the fuel tank by starting the engine and letting
it run until the fuel lines and carburetor are empty.
• Never use engine or carburetor cleaner products in the
fuel tank or permanent damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in mini-
mizing the formation of fuel gum deposits during stor age.
Add stabilizer to gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer container.
Run engine at least 10 minutes after adding stabilizer to
allow the stabilizer to reach the carburetor. Do not empty
the gas tank and carburetor if using fuel stabilizer.
ENGINE OIL
Drain oil (with engine warm) and replace with clean engine
oil. (See “ENGINE” in the Maintenance section of this

See appropriate section in manual unless directed to a Husqvarna or other authorized repair center.
