the wire from the spark plug.

General Recommendations

The warranty on this snow thrower does not
cover items that have been subjected to
operator abuse or negligence. To receive full
value from the warranty, the operator must
maintain the snow thrower as instructed in this
manual.

Some adjustments must be made periodically to
properly maintain the snow thrower.

After Each Use

Check for any loose or damaged parts.

Tighten any loose fasteners.

Check and maintain the auger.

Check controls to make sure they are
functioning properly.

If any parts are worn or damaged, replace
immediately.

Check all safety and instruction decals and
labels. Replace any decals or labels that
are missing or cannot be clearly read.

All adjustments in the Maintenance section of
this manual should be checked at least once
each season.

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 14)

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

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.

(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.

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)

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 (15)

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 (15)

will

become worn. The

scraper bar (15)

, in

conjunction with the skids, must be adjusted to
allow 1/8 inch (3 mm) clearance between the

scraper bar (15)

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 (15)

to the

auger housing

(4)

4. Adjust the

scraper bar (15)

to allow 1/8 inch

(3 mm) clearance between the

scraper bar

(15)

and the sidewalk or area to be cleared.

5. Tighten the carriage bolts and nuts. Make

sure that the

scraper bar (15)

is parallel with

the sidewalk or area to be cleared.

6. To extended the life of the

scraper bar (15)

remove and reverse the mounting of the

scraper 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

(Figure 16)

1. To check for correct adjustment, disconnect

the

“Z” fitting (1)

from the

drive lever (2)

2. Move the

drive lever (2)

forward until the

drive lever (2)

is contacting the
