SNOW THROWING TIPS

.This snow thrower will propel itself for-

ward when the handle is raised enough

to cause the auger blades to contact the

ground. The auger will stop when control

switch lever is released.

.For most efficient snow throwing, turn the

discharge chute deflector to throw snow

downwind, and slightly overlap each

swath. In light snow take up to a full cut

and in heavy snow take less than a full

cut.

.The distance snow will be discharged

can be adjusted by moving the discharge

chute deflector. Raise the deflector for

more distance or lower the deflector for

less distance.

.In windy conditions, lower the chute de-

flector to direct discharged snow close to

the ground where it is less likely to blow

into unwanted areas.

.Keep the area to be cleared free of

stones, toys and other foreign objects for

safety and to prevent damage to the

snow thrower.

.Do not use the auger propelling feature

when clearing gravel or crushed rock

driveways. Move the handle down to

raise the auger slightly.

.The allowable forward speed of the snow

thrower is dependent on the depth and

weight of the snow. Experience will es-

tablish the most effective method of using

the snow thrower under different condi-

tions.

DRY AND AVERAGE SNOW

.Snow up to eight inch depth can be re-

moved rapidly and easily by walking at a

moderate rate. For snow or drifts of a

greater depth you may find it desirable to

slow your pace to allow the discharge

chute to dispose of the snow as rapidly

as the auger receives the snow.

.Plan to have the snow discharged in the

direction the wind is blowing.

WARNING: Always stand be-

hind snow thrower (operator’s

position) when starting motor.

Do Not put hands, feet, hair or loose

clothing on near the discharge chute de-

flector or auger housing while the motor

is running.

WARNING: Objects such as

gravel, rocks or other debris, if

struck by the auger, may be

thrown with sufficient force to cause per-

sonal injury or property damage.

Not for Reproduction

OPERATION

16

WET PACKED SNOW

Move slowly into snow of this condition. The

greater the depth, the slower you should go.

When it appears that the wet, packed snow

is causing the auger to slow down and the

chute to clog, back off and begin a series of

short jabs into the snow. These short back

and forth, 4 to 6 inch, jabbing motions will

“belch” the snow from the chute.

SNOW BANKS AND DRIFTS

In snow of greater depth than the unit, use

the ”jabbing” technique described above.

Turn the discharge chute away from the

snow bank. More time will be required to re-

move snow of this type than level snow.

TO ADJUST THE DRIVE BELT

If the motor drive pulley and the auger drive

pulley are not aligned properly, excessive

belt wear will occur. To check the pulley

alignment, proceed as follows:

1. Remove the belt cover (see “To Remove

Belt Cover”).

2. Place a straight edge approximately 16”

long across the large auger pulley, con-

tacting two points and extending to the

motor pulley (see Figure 13). The outside

of the motor pulley must be flush with the

straight edge. If the pulleys are aligned,

skip to the last step). Figure 13

MOTOR SERVICE

Motor repairs and adjustments should be

done by technicians trained to work on snow

thrower type motors. Take your snow throw-

er to an authorized service center for repair

and adjustment.

SNOW THROWER STORAGE

.Thoroughly clean the snow thrower.

.Lubricate all the lubrication points (see

the Maintenance section).

.Be sure that all nuts, bolts and screws

are securely fastened. Inspect all visible

moving parts for damage, breakage and

wear. Replace if necessary.

.Touch up all rusted or chipped paint sur-

faces; sand lightly before painting.

.Cover the bare metal parts of the blower

housing and auger with rust preventative,

such as a spray lubricant.

.Store the snow thrower indoors in a

clean, dry, locked-up place out of reach

of children.

.Store the extension cord with the snow

thrower to prevent misplacement.

.Inspect the snow thrower thoroughly for

worn, loose or damaged parts. Make all

necessary repairs before storing snow

thrower.

.Inspect extension cord thoroughly for

signs of excess wear or damage. If worn

or damaged, replace with a U.L. listed

cord suitable for outdoor use in cold

weather.

NOTE: A yearly checkup or tune-up at an

authorized service center is a good way

of ensuring that your snow thrower will

provide maximum performance for the

next season.
