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
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

How To Remove The Snow Hood
To access the spark plug, the snow hood must
be removed as follows:
1. (Figure 13) Remove the choke control
knob (1).
2. Remove the ON/OFF key (2).
3. Remove the four mounting screws (3).
4. (Figure 14) Slowly remove the snow hood
(4). Make sure that the primer button hose
and the ignition wire are not disconnected.
5. To install the snow hood (4), first make sure
that the primer button hose and the ignition
wire are connected.
6. (Figure 15) Mount the snow hood (4) to the
engine and secure with the four mounting
screws.
7. (Figure 16) Align the tab (5) on the choke
control knob (6) with the slot (7) in the
snow hood.
8. Connect the choke control knob (6) with
the choke shaft (7). Make sure the choke
control knob (6) is properly installed. If the
choke control knob (5) is not installed cor-
rectly, the choke will not operate.
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 18)
1. TOcheck 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 plastic
bumper (3).
3. 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.
_k ARNING: Drain the gasoline out-
doors, away from fire or flame.
2. (Figure 18) Disconnect the "Z" fitting (1)
from the drive lever (2).
3. (Figure 19) Pull the spring cover up to ex-
pose the spring (5). Push the cable (6)
through the spring (5) to expose the square
end (7) on the cable (6).
4. Hold the square end (7) with pliers and ad-
just the Iocknut (8) in or out until the excess
slack is removed.

5. Pull the cable (5) beck through the spring
(5).
6. (Figure 18) Connect the "Z" fitting (1) to the
drive lever (2).
NOTE: When the auger drive belt is adjusted
or replaced, check and adjust the cable.
HOW TO Adjust The Belts
The belts will stretch during normal use. If you
need to adjust the belts due to wear or stretch,
proceed 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 The Cables" in
the Maintenance section. If the adjustment is
correct, then check the condition of the auger
drive belt. if the auger drive belt isdamaged,
replace the auger drive belt. See "How To Re-
place The Belts" in the Maintenance section. If
the auger drive belt is loose, adjust as follows.
1. Disconnect the spark plug wire.
2. (Figure 20) Remove screw (2) from belt
cover (1). Remove the belt cover (1).
3. (Figure 21) Loosen the nut (2) on the idler
pulley (3). Move the idler pulley (3) 1/8 inch
toward the auger drive belt (4).
4. Tighten the nut (2).
5. (Figure 22) Depress the auger drive lever.
Check the tension on the auger drive belt
(4). in correct adjustment, the auger drive
belt (4) will deflect 1/2 inch (5) with moder-
ate pressure, if the adjustment is not correct,
repeat the adjustment.
6. (Figure 20) Install the belt cover (1). Tighten
screw (2).
7. Check the adjustment of the auger drive
cable. See "How To Check And Adjust The
Cables" in the Maintenance section.
8. Attach the spark plug wire.
How To Adjust The Traction Drive Belt
After approximately ten hours of operation, a
new belt will stretch and require an adjustment
of the belt tension. Also. if your snow thrower
experiences a loss of power under heavy load,
check the condition of the traction drive belt. If it
is damaged or loose, replace it (see "How To
Replace The Belts" in this section of the manu-
al).
1. Disconnect the spark plug wire.
2. Unlock both left and right wheel locks. See
"How To Use The Wheel Lockout" in the Op-
eration section.
3. (Figure 20) Remove screw (2) from belt
cover (1). Remove the belt cover (1).
4. (Figure 21) Loosen the nut on the traction
idler pulley (12). Move the traction idler
pulley (12) 1/8 inch toward the traction
drive belt (13).
5. Tighten the nut (2).
6. (Figure 22) Depress the traction drive lever.
Check the tension on the traction drive belt
(4). In correct adjustment, the traction drive
belt (4) will deflect 1/2 inch (5) with moder-
ate pressure. If the adjustment is not correct,
repeat the adjustment.

DO NOT over tighten belt. If the belt
is too tight, the drive will not disen-
gage. Before operating, check the
belt tension following the instructions in
step 8.
7. (Figure 20) Install the belt cover (1). Tighten
screw (2).
8. Attach the spark plug wire. Before operation,
check the belt tension as follows:
a. Unlock both left and right wheel locks.
See "How To Use The Wheel Lockouts" in
the Operation section.
b. Move the shift lever to NEUTRAL posi-
tion.
c. DO NOT engage the traction drive lever.
d. Start the engine.
e. Slowly move the shift lever forward.
Watch the axles for rotation. If the axles
rotate, the traction drive belt is too tight.
f. If the belt is too tight, again adjust the
belt. After each adjustment, check the
belt tension before operating.
9. In correct adjustment, the snow thrower will
notexperience a loss of power under heavy
load and the drive will automatically disen-
gage when the traction drive lever is re-
leased

HOW TO Replace The Belts
The drive belts are of special construction and
must be replaced with original factory replace-
ment belts available from your nearest autho-
rized service center.
Some steps require the assistance of a second
person.
How To Remove the Auger Drive Belt
If the auger drive belt is damaged, the snow
thrower will not discharge snow. Replace the
damaged belt as follows.
1. Disconnect the spark plug wire.
2. (Figure 23) Loosen the bolts (3) on each
side of the bottom panel (2).
3. Remove the bottom panel (2).
4. (Figure 20) Remove screw (2) from belt
cover (1). Remove the belt cover (1).
5. (Figure 21) Loosen the belt guide (9). Pull
the belt guide (9) away from the stack
pulley (10).
6. Pull the idler pulley (3) away from the au-
ger drive belt (4).
7. Remove the old auger drive belt (4) from
the stack pulley (10) and from the auger
drive pulley (11). Replace the auger drive
belt (4) with an original factory replacement
belt available from an authorized service
center.
8. Install the new auger drive belt (4) onto the
stack pulley (10) and onto auger drive
pulley (11),
9, Adjust the auger drive belt (4), See "Row To
Adjust The Auger Drive Belt" in the Mainte-
nance section.
10.Adjust the auger belt guide (9). See "How
To Adjust The Belt Guide" in the Mainte-
nance section.
11.(Figure 20) Install the belt cover (1). Tighten
screw (2).
12.Check the adjustment of the cables. See
