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

empty.

•

Never

use engine

may

occur.

•

Use

fresh

fuel

next

season.

NOTE:

Fuel

stabilizer

is

an

acceptable

al-

ternative

in

minimizing

the

formation

of fuel

gum

deposits

during

storage.

Add

stabilizer

to gasoline

in

fuel tank

or storage

container.

Always

follow

the mix ratio

found

on stabilizer

container.

Run
