Ariens Sno-Thro ST4-65R - Manual (Page 6)

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.
