of

bearings

and

other

moving

parts.

Mix

the

gasoline

and

oil

in

a

clean

Always

use

fresh,

unleaded,

winter

grade

gasoline;

never

use

‘stale’

gasoline

left

over

from

Note:

The

length

of

the

is

adjustable.

However,

you

will

not

have

to

do

this

frequently

since

the

operating

tension

on

the

drive

belt

is

maintained

by

the

clutch

engaging

spring

on

the

heavy

load

or

you

hear

the

drive

belt

squeal

when

entering

heavy

snow,

reduce

the

length

of

the

cable.

This

will

increase

the

pressure

applied

by

the

idler

pulley

on

the

drive

belt.

If

auger

continues

to

turn

after

the

is

released,

the

is

too

tight.

Increase

the

length

of

the

that

the

slightly

slack

when
