CAUTION: Any greasing or oiling of the
above components can cause contamina-
tion of the friction whe
el (3). If the disc
drive plate (1) or the friction whe
el (3) be-
come contaminated with grease or oil,
damage to the friction whe
el will result.
3. T
he auger gear case is lubricated at the fac-
tory and does not require additional lubrica-
t
ion. If for some reason the lubricant leaks
o
ut, h
ave the auger gear case checked by a
factory authorized service center.
How To Adjust The Height Of The Skids
(Figure 2)
This snow thrower is equipped with two height
adjustable skids (7). These skids elevate the
f
ront of the snow thrower.
For normal hard sur-
faces, such as a paved driveway or walk, adjust
the skids as follows.
1. Put th
e snow thrower on a level surface.
2. M
ake sure both tires are equally inflated.
The correct air pressure is 14 PSI (1 BAR) to
1
7 PSI (1.25 BAR). Do not exceed the maxi-
m
um amount of air pressure shown on the
s
ide of the tire.
3. Put th
e extra shear bolts (found in the parts
bag)
under each end of the scraper bar (15)
next to the a
djustable skids (7).
4. L
oosen the mounting nuts (16) that hold the
adjustable skids (7).
To bring the front of the
snow thrower down, raise each adjustable
s
kids (7)
. Tighten the mounting nuts (16).
NOTE: For rocky or une
ven surfaces, raise
the front of the snow thrower by moving the
a
djustable skids (7) down.
WARNING: Be certain to maintain
proper ground clearance for the
a
rea to be cleared. Objects such
a
s gravel, rocks or other debris, if struck
by the impeller, can be thrown with suffi-
c
ient force to cause personal injury, prop-
e
rty damage or damage to the snow throw-
er.
How To Adjust
The Scraper Bar (Figure 2)
After considerable use, the scraper bar (15) will
become worn. The s
craper bar (15), in con-
junction with the skids, must be adjusted to allow
1
/8 inch clearance between the s
craper bar
(15)
and the sidewalk or area to be cleared.
1. Put th
e snow thrower on a level surface.
2. M
ake sure both tires are equally inflated.
The correct air pressure is 14 PSI (1 BAR) to
1
7 PSI (1.25 BAR). Do not exceed the maxi-
m
um amount of air pressure shown on the
s
ide of the tire.
3. L
oosen the carriage bolts and nuts that hold
the s
craper bar (15) to the auger housing
(4).
4. Adjust the s
craper bar (15) to allow 1/8 inch
clearance between the s
craper bar (15) and
the sidewalk or area to be cleared.
5. Ti
ghten the carriage bolts and nuts. Make
sure that the s
craper bar (15) is parallel with
the sidewalk or area to be cleared.
6. To
extend the life of the scraper bar (15),
remove and reverse the mounting of the
s
craper bar (15).
How To Check And Adjust The Cables
The traction drive cable and the auger drive
cable are adjusted at the factory.
During normal
use, a cable can become stretched and must be
checked and adjusted as follows.
How To Check The Cables (Figur
e 11)
1. To check for correct adjustment, disconnect
the “Z” fitting (1) f
rom the drive lever (2).
2. M
ove the drive lever (2) forward until the
drive lever (2) is contacting the plastic
bumper (3).
3. The control cable is correctly adjusted if the
c
enter of the “Z” fittin
g (1) is aligned (4)
with the hole in the d
rive lever (2) and there
is n
o slack in the cable .
How To Adjust The Aug
er Drive Cable
1. R
emove the gas from the gas tank. Stand
the snow thrower up on the front end of the
a
uger housing.
WARNING: Dra
in the gasoline out-
door
s, away from fire or flame.
2. (Figure 11) Disconnect the “Z” fitting (1)
from the d
rive lever (2).

th
rough the spring (5) to expose the square
end (
7) on the cable (6).
4. H
old the square end (7) with pliers and ad-
just the loc
knut (8) in or out until the excess
slack is removed.
5. P
ull the cable (6) back through the spring
(5).
6. (Figur
e 11) Connect the “Z” fitting (1) to the
drive lever (2).
NOTE: When the auger drive belt is adjus
ted
or replaced, check and adjust the cable.
How To Adjust The Traction Drive Cable
1. R
emove the gas from the gas tank. Stand
the snow thrower up on the front end of the
a
uger housing.
WARNING: Drain the gasoline out-
door
s, away from fire or flame.

How To Adjust The Belts
The belts will stretch during normal use. If you
need to adjust the belts due to wear or stretch,
p
roceed as follows.
How To Adjust The Auger Drive Belt
If the snow thrower will not discharge snow,
check the adjustment of the auger drive cable.
See “How To Check And Adjust Th
e Cables” in
the Maintenance section. If the adjustment is
c
orrect, then check the condition of the auger
d
rive belt. If the auger drive belt is damaged,
r
eplace the auger drive belt. See “How To
Re-
place The Belts” in the Maintenance section. If
t
he auger drive belt is loose, adjust as follows.
1. Disconnect the spark plug wire.

4. Ti
ghten the nut (2).
5. (Figur
e 15) Depress the auger drive lever.
Check the tension on the a
uger drive belt
(4).
In correct adjustment, the auger drive
belt (4)
will deflect 1/2 inch (5) with moder-
ate pressure. If th
e adjustment is not correct,
repeat the adjustment.
6. (Figur
e 13) Install the belt cover (1). Tighten
