OPERATING TIPS

1. PRE-OPERATION PRECAUTIONS 3. DEPTH ADJUSTMENT

a. Before the first snowfall, be sure the area

on which the Sno-Thro is to be operated is free of

sticks, stones, toys, or other obstructions which

might be picked up by the machine during operation.

WARNING

Do not allow children to run through

the snow being discharged from the

machine. Small objects picked up

by the machine may be thrown out

of the chute with considerable force

and can cause serious injury.

b. Always allow the engine to warm up to opera

ting temperature before operating the machine in

snow.

How clean the Sno-Thro will plow is determined

by the adjustment of the runners. See paragraph 7

of Operating Instructions. When plowing on concrete

or other hard surfaces, these runners should be ad

justed so that they are approximately 1/8-inch below

the scraper blade. When plowing gravel driveways

or other gravel areas, adjust the runners so that

they are 1-1/4-inch below tiie scaper blade.

4. PLOWING

a. When plowing reasonable depths of ordinary

snow, it is only necessary to guide the machine along

the path to be plowed and to adjust the chute to blow

the snow with the wind. When making the second

pass on a sidewalk or driveway, allow the machine to

overlap the previous path slightly to insure complete

removal of snow.

c. Operate the machine in a cleared area be

fore operating in snow for the first time. Become

familiar with all controls before attempting to plow.

2. CHUTE ADJUSTMENT

a. The distance the Ariens Sno-Thro will throw

the snow will depend on the type of snow being

plowed. In general, the position of the deflector

will determine the distance the snow will be thrown.

Tipping the deflector down will decrease the throw

and tipping the deflector up will increase the throw.

b. The distance the snow is blown can also be

controlled to some extent by the engine speed.

Slowing down the engine by means of the throttle

control will decrease the throw and increasing speed

will increase the throw. By a combination of engine

speed and deflector adjustment, the snow can be

blown a distance suitable for nearly every situation.

NOTE

When operating the Sno-Thro in wet

snow, occasionally a sufficient

amount of snow may stick inside

the chute causit^ partial clogging.

To prevent this, it is suggested

that the inside of the chute be

coated with a light layer of "paste"

or "spray" wax. It is recommended

that the inside of the chute be waxed

two or three times each season.

b. When plowing through a very heavy drift, such

as one formed by the passing of the street plow, it

may be necessary to "inch" into the drift when making

the first pass. To do so, allow the machine to enter

the drift and then declutch. Allow the machine to

blow away the accumulation of snow and then move

the machine forward deeper into the drift by re

leasing the clutch handle. Again declutch and allow

the machine to clear away the snow. Continue this

process imtil a complete path has been cleared

through the drift. On the second pass through the

drift, allow the path of the machine to overlap the

first path.

5. SHEAR BOLT REPLACEMENT

Occasionally a small object may enter the rotor

and become jammed in the blades. When this occurs

the shear bolts, located on the shaft on which the

rotor is mounted, will break and allow the rotor to

turn freely on the shaft. Before plowing can be con

tinued, this shear bolt must be replaced. See figure

2. USE ONLY ARIENS SHEAR BOLTS. USE OF

OTHER TYPES OF BOLTS MAY RESULT IN SEVERE

DAMAGE TO MACHINE.

WARNING

If it becomes necessary to replace

the shear bolts or necessary to

remove any obstruction from either

the rotor, blower, or chute, STOP

THE ENGINE.

NOTE

Each time a shear bolt is replaced, the rakes must be oiled

and turned on the shaft by hand several times to insure

that they will not bind.
