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

 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.

3.

(Figure 14) 

Loosen the

 bolts (3)

 on each

side of the 

bottom panel (2)

(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) 

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.

cable (6)

.

4. Hold the 

square end (7)

 with pliers and

adjust the

 locknut (8) 

in or out until the

excess slack is removed.

5. Pull the 

cable (6)

 back through the 

spring

(5).

6.

(Figure 16) 

Connect the 

“Z” fitting (1)

or replaced, check and adjust the cable.

How To Adjust The Traction 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.

2.
