Fuel; Adding A Fuel Stabilizer To Extend Fuel Storage Life; Draining The Fuel Tank And Carburetor - PowerWasher pwh2600 Instruction Manual

Fuel

Gasoline will oxidize and deteriorate in storage. Old gasoline will cause hard starting, and it
leaves gum deposits that clog the fuel system. If the gasoline in your engine deteriorates during
storage, you may need to have the carburetor and other fuel system components serviced or
replaced.
The length of time that gasoline can be left in your fuel tank and carburetor without causing
functional problems will vary with such factors as gasoline blend, your storage temperatures, and
whether the fuel tank is partially or completely lled. The air in a partially lled fuel tank promotes
fuel deterioration. Very warm storage/temperatures accelerate fuel deterioration. Fuel
deterioration problems may occur within a few months, or even less if the gasoline was not fresh
when you lled the fuel tank.
The Distributor's Limited Warranty does not cover fuel system damage or engine performance
problems resulting from neglected storage preparation.
You can extend fuel storage life by adding a fuel stabilizer that is formulated for that purpose, or
you can avoid fuel deterioration problems by draining the fuel tank and carburetor.

ADDING A FUEL STABILIZER TO EXTEND FUEL STORAGE LIFE

When adding a fuel stabilizer, ll the fuel tank with fresh gasoline. If only partially lled, air in the
tank will promote fuel deterioration during storage. If you keep a container of gasoline for
refueling, be sure that it contains only fresh gasoline.
1. Add fuel stabilizer following the manufacturer's instructions.
2. After adding a fuel stabilizer, run the engine outdoors for 10 minutes to be sure that treated
gasoline has replaced the untreated gasoline in the carburetor.
3. Stop the engine, and move the fuel valve to the OFF position.

DRAINING THE FUEL TANK AND CARBURETOR

1. Place an approved
container below the carburetor,
and use a funnel to avoid spilling
fuel.
2. Remove the carburetor drain bolt
and sealing washer, and then
move the fuel valve lever to the ON
position.
3. After all the fuel has drained into
the container, reinstall the drain
bolt and sealing washer. Tighten
them securely.
