STORAGE

When

your

saw

is

to

be

stored

for

over

30

days,

always:

1.

Drain

fuel

tank

in

a

safe

manner.

See

"FuelingYour

Engine

—Fuel

Safety"

2.

Start

engine

and

allow

to

run

at

idle

speed

until

the

engine

stops.

NOTE:

Running

the

engine

until

it

stops

will

re-

move

most

of

the

fuel

from

the

fuel

system.

NOTE:

It

is

important

to

prevent

gum

deposits

from

forming

in

essential

fuel

systems

parts

such

as

the

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

sys-

tem

of

an

engine

while

in

storage.
