As Required
The following adjustment should be preformed
more than once each season.
1. Adjust the auger drive belt after the first 2 to
4 hours, again at mid�season, and twice
each season thereafter. See “How To Adjust
The Auger Drive Belt” in the Maintenance
section.
Lubrication
Every 10 Hours
(Figure 13)
1. Lubricate the
Zerk fittings (1)
every ten
hours with a grease gun.
2. Each time a shear bolt is replaced, the auger
shaft must also be greased.
3. Lubricate all pivot points.
Every 25 Hours
Chute Rotation Gear
(Figure 5)
Lubricate the
chute rotation gear (1)
with automotive type oil.
Chains

(Figure 1)
Move the
speed shift lever (6)
to
first gear.
2. Remove the gas from the gas tank. Stand
the snow thrower up on the front end of the
auger housing (4)
.
WARNING: Drain the gasoline
outdoors, away from fire or flame.

Loosen the
bolts (3)
on each
side of the
bottom panel (2)
.
4. Remove the
bottom panel (2).
5.
(Figure 15)
Lubricate the
chains (5)
with a
chain type lubricant.
6. Wipe the
hexshaft and sprockets (6)
with
5W30 motor oil.
NOTE: If grease or oil come in contact
with the disc drive plate (1) or the friction
wheel (3), damage can result. Clean off
any oil or grease with a alcohol base
solvent.

Install the
bottom panel (2)
.
8. Tighten the
bolts (3)
on each side of the
bottom panel (2)
.
Items Not To Lubricate
(Figure 15)
1. Do not lubricate the
hex shaft and
sprockets (6)
. All bearings and bushings are
lifetime lubricated. For storage, put a slight
amount of 5W�30 motor oil on a cloth and
wipe the
hex shaft and sprockets (6)
to
prevent rust.
2. If grease or oil comes in contact with the
disc drive plate (1)
or the
friction wheel
(3)
, the
friction wheel (3)
can be damaged.
Make sure to thoroughly clean the
disc drive
plate (1)
and the
friction wheel (3)
.
CAUTION: Any greasing or oiling of the
above components can cause
contamination of the friction wheel (3). If
the disc drive plate (1) or the friction
wheel (3) become contaminated with
grease or oil, damage to the friction wheel
will result.
3. The auger gear case is lubricated at the
factory and does not require additional
lubrication. If for some reason the lubricant
leaks out, have the auger gear case checked
by a factory authorized service center.
How To Adjust The Height Of The Skids
(Figure 1)
This snow thrower is equipped with two height
adjustable skids (7).
These skids elevate the
front of the snow thrower. For normal hard
surfaces, such as a paved driveway or walk,
adjust the skids as follows.
1. Put the snow thrower on a level surface.
2. Make sure both tires are equally inflated. The
correct air pressure is 14 PSI (1 BAR) to 17
PSI (1.25 BAR). Do not exceed the
maximum amount of air pressure shown on
the side of the tire.
3. Put the extra shear bolts (
found in the parts
bag
) under each end of the
scraper bar (17)
next to the
adjustable skids (7)
.
4. Loosen the
mounting nuts (16)
that hold the
adjustable skids (7)
. To bring the front of the
snow thrower down, raise each
adjustable
skids (7)
. Tighten the
mounting nuts (16)
.
NOTE: For rocky or uneven surfaces, raise
the front of the snow thrower by moving the
adjustable skids (7) down.
WARNING: Be certain to maintain
proper ground clearance for the
area to be cleared. Objects such as
gravel, rocks or other debris, if struck by
the impeller, can be thrown with sufficient
force to cause personal injury, property
damage or damage to the snow thrower.
How To Adjust The Scraper Bar
(Figure 1)
After considerable use, the
scraper bar (17)
will
become worn. The
scraper bar (17)
, in
conjunction with the skids, must be adjusted to
allow 1/8 inch clearance between the
scraper
bar (17)
and the sidewalk or area to be cleared.
1. Put the snow thrower on a level surface.
2. Make sure both tires are equally inflated. The
correct air pressure is 14 PSI (1 BAR) to 17
PSI (1.25 BAR). Do not exceed the
maximum amount of air pressure shown on
the side of the tire.
3. Loosen the carriage bolts and nuts that
hold the
scraper bar (17)
to the
auger
housing (20)
.
4. Adjust the
scraper bar (15)
to allow 1/8 inch
clearance between the
scraper bar (17)
and
the sidewalk or area to be cleared.
5. Tighten the carriage bolts and nuts. Make
sure that the
scraper bar (17)
is parallel with
the sidewalk or area to be cleared.
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
(Figure 16)
1. To check for correct adjustment, disconnect
the
“Z” fitting (1)
from the
drive lever (2)
.
2. The control cable is correctly adjusted if the
center of the
“Z” fitting (1)
is
aligned (4)
with the hole in the
drive lever (2)
and there
in no droop in the cable
.
How To Adjust The Auger Drive Cable
1. Remove the gas from the gas tank. Stand
the snow thrower up on the front end of the
auger housing.
WARNING: Drain the gasoline
outdoors, away from fire or flame.
