b.The 120V A.C. starter is equipped

with a three-wire power cord and
plug and is designed to operate on
120V A.C. household current. The
starter must be properly grounded
at all times to avoid the possibility
of injury or death from electrical
shock. Determine that your house
wiring is a Ground Fault Interrupted
(G.F.I.) three-wire grounded sys­tem, or ask a licensed electrician if
you are not sure. If your house
wiring system is not a G.F.I. three­wire grounded system, DO NOT use
the electric starter under any condi­tion. If your house wiring system is
grounded but a G.F.I. three-prong
wall receptacle is not available at
the location your starter will be
used, one should be installed by a
licensed electrician.

c. Inspect the power cord for damage

before use. If it is damaged, do not
use it.

d.Stand on dry ground when handling

the power cord. Do not handle the
power cord with wet hands or wet
gloves. Do not use the electric
starter if it is raining.

e. Connect the cord to the electric

starter first, and then plug the cord
into a properly grounded outlet
(this lessens the chances of sparks
from occurring near the engine).

f. Do not abuse the power cord. Do

not pull the unit by the cord. Do not
pull the cord to disconnect it from
the outlet. Keep the cord away
from sharp edges, oil, and exces­sive heat.

g.Store the power cord in a secure

place, safely out of the reach of
children.

7. Adjust the skid shoes and scraper
blade so the collector (auger/impeller)
housing clears gravel or crushed rock
surfaces.

8. Never attempt to make any adjust­ments while the engine is running
(except when specifically recom­mended by the the manufacturer).

Operation

1. The operator of the unit is responsible
for the safety of all persons in the op­erating zone of the unit.

2. Before starting the unit, disconnect
the spark plug wire and check the col­lector (auger/impeller) housing and
discharge chute to make sure they are
free of ice.

3. Disengage all clutches before starting
the engine.

4. Let the unit adjust to outdoor temper­ature before use.

5. Check the operation of the controls
before using the unit. Do not operate
the unit unless all controls are operat­ing properly.

PRE-OPERATION CHECKLIST

Perform the following checks with the
engine stopped and the spark plug wire
disconnected from the spark plug.

1. Review Section 1: Safety and Section 3:
Features and Controls in this manual.

2. Check for loose or missing hardware.
Tighten or replace as needed.

3. Visually check inside the collector
(auger/impeller) housing and the dis­charge chute and remove any debris.

4. With the unit on level ground, check the
engine oil level according to the in­structions in the engine manual. The oil
level should be at the “FULL” mark on
the dipstick.

5. Turn off engine and let it cool for at
least 2 minutes before removing the
gasoline fill cap. Remove the fill cap
and check the level of gasoline in the
fuel tank according to the instructions
in the engine manual.

Use fresh, clean, unleaded gasoline
(refer to engine manual for additional
gasoline information). Do not overfill
fuel tank. Fill to approximately 1-1/2
inches below top of neck to allow for
fuel expansion. DO NOT MIX OIL
WITH GASOLINE! Tighten the gasoline
fill cap securely.

6. The unit should be adjusted so the col­lector (auger/impeller) housing and

the scraper blade (A, Figure 4-1) are
1/8" above the surface to be cleared. If
clearing gravel or uneven surfaces, in­crease the clearance so gravel or other
foreign objects are not scooped up
into the auger.

To adjust the collector housing

height/scraper blade height:
a. Move the unit onto a level surface.
b. Loosen the four screws securing the

two skid shoes (B, Figure 4-1).

c. Adjust the skid shoes (B) until they

are in the correct position to support
the collector (auger/impeller) hous­ing and the scraper blade (adjust
skid shoes equally to prevent uneven
snow removal).

d. Tighten the four screws.

e. The scraper blade (A, Figure 4-1)

can also be adjusted. Adjust the
scraper blade at the four carriage
bolts (C, Figure 4-1). Adjust the bot­tom edge of the scraper blade so it is
parallel to the bottom edge of the
auger.

7. Use the lever on the Discharge Chute
Deflector Cap (D, Figure 4-3) to adjust
the deflector cap to the desired angle
of discharge. Usually keep the angle
of the deflector cap low, especially in
windy conditions.

8. Rotate the Discharge Chute Control
Rod (E, Figure 4-3) and check for
binding. Leave the discharge chute
pointing straight ahead.

9. Check the Auger Drive and Wheel
Drive control levers (F and G, Figure 4-

3) for freedom of movement.

10. Check the tire pressure. Inflate both
tires evenly to 8 to 12 PSI (55 to 82
Kpa).

11. Apply silicone spray on the inside of
the discharge chute, the chute dis­charge deflector cap, the collector
(auger/impeller) housing, and on the
augers. This will help prevent snow
from sticking (do not allow silicone
spray on rubber or plastic: damage
can result).

12. Reconnect the spark plug wire (see
engine manual) to the spark plug.

STARTING THE ENGINE

1. Complete the Pre-Operation Checklist.

after a snowfall.

• Run the engine at full throttle (the “”
position).

• Apply silicone spray onto the inside of

the collector (auger/impeller) housing,
the discharge chute, the deflector cap,
and also on the augers to help prevent
snow from sticking. (Do not spray sili­cone on rubber or plastic: damage will
result).

• Direct discharge downwind.

• If a smooth area is being cleared, ad-

just the skid shoes so the scraper
blade is approximately 1/8" (3mm)
from the ground.

• If a rough or gravel area is being

cleared, adjust the skid shoes so the
scraper blade clears the rough or
gravel surface.

• Use slow travel speeds for safety and

to prevent overloading the unit.

Section 4: Operation

CAUTION

Transmission damage could occur if the
Gear Shift Lever is moved when the unit
is in motion. Carefully follow the shift­ing instructions.

Use extreme caution when operating the

in the reverse position.

WARNING

Thoroughly inspect the area where the
unit will be used before the first snow­fall. Remove all doormats, sleds,
boards, wires and other debris to pre­vent injury from thrown objects.

WARNING

Stop the engine and remove the spark
plug wire from the spark plug before re­moving any debris from the collector
(auger/impeller) housing.

WARNING

14

SNOW THROWING PATTERNS

Use the snow clearing pattern shown in
Figure 4-4 when snow can only be thrown
to one side. Begin throwing snow closest
to the side opposite where it can be
thrown and direct the discharge away
from that side. When turning the unit
around after each pass, rotate the dis­charge chute as you proceed so snow
continues to be thrown in the proper
direction.

Use the snow clearing pattern shown in
Figure 4-5 to throw snow to both sides.
When turning the unit, rotate the dis­charge chute as necessary to throw snow
in the proper direction.

Section 4: Operation

Do not use your hands or feet to dislodge
snow from inside the collector
(auger/impeller) housing or the dis­charge chute. Any contact with the
moving parts will cause serious injury.

Stop the engine and remove the spark
plug wire from the spark plug and use a
long (at least 3-feet [100CM] long)
wooden stick to unclog these areas.

WARNING

Figure 4-5

ENGINE MAINTENANCE

IMPORTANT: Refer to the Engine Owner’s
Manual for complete engine maintenance
information.

Engine Oil

• Check the engine oil level each time be­fore starting the unit and after each 5
hours of operation. With the engine on
level ground, the oil level should be at
the “FULL” mark on the dipstick. Refer to
the engine manual for oil specifications
and complete instructions.

• Change the engine oil according to the
maintenance intervals and instructions in
the engine manual.

TIP: When changing engine oil, fold a
piece of cardboard or aluminum foil into a
shallow “V”, and position it so the oil will
drain through it into the container.

To check the engine oil level:

1. Move the unit to a level surface. Stop

the engine, wait for all parts to stop
moving and disconnect the spark
plug wire from the spark plug.

2. Remove the oil dipstick and wipe the

dipstick with a clean cloth.

3. Screw the oil dipstick back into the oil

fill hole. Remove the dipstick and
check the oil level – it should be up to
the “FULL” mark on the dipstick. If
low, add oil by using the oil dipstick
as a guide. Refer to engine manual
for detailed instructions.

Ignition System

The engine has an electronic ignition sys­tem which does not use points or a con­denser. The spark plug is the only item re-

quiring maintenance in this system.

Spark Plug

Annually or every 100 hours of operation,
remove and inspect the spark plug.
Replace the spark plug if the electrode is
pitted or burned or if the porcelain is
cracked. Refer to the engine manual for
correct spark plug specifications and ser­vicing instructions.
NOTE: Use of an incorrect plug can dam-

age the engine.

Carburetor

The carburetor has been adjusted at the
factory and should not require additional
adjustment. Refer to the engine manual or
contact your dealer for additional carbure-

tor information.

LUBRICATION

At the beginning and end of each season
or after every 25 hours of operation, lubri-

cate the unit as recommended below. The
engine must be stopped and the spark
plug wire disconnected before performing
any lubrication.

1. Lightly oil both the discharge chute
cap pivot points (A, Figure 5-1).

2. Lightly oil the discharge chute control
rod pivot points where the control rod
enters the control panel bearing (B,
Figure 5-3), the support tab (C) and the
support on the left rear of unit housing
(D, Figure 5-4).

3. Remove the left wheel (E, Figure 5-1).
Clean the wheel shaft and apply multi­purpose grease to the wheel shaft.
Reinstall the wheel.

4. Apply oil to the bearings on the sides of
the auger shaft (F, Figure 5-1).

5. Clean dirt and old grease from the
flange at the bottom of the discharge
chute (G, Figure 5-1). Apply multi-pur­pose grease to the worm gear (H) and
to the toothed portion of flange and the
flange.

6. Lightly lubricate the handlebar control
levers at pivot points (J, Figure 5-3)
with oil or a non-silicone spray. Do
not get oil or lubricating spray on
levers.

7. Lightly oil the pivot points on the gear
shift control lever (K, Figure 5-3).

8. Remove the two shear bolts (L, Figure
5-5) from the auger shaft, then lubri­cate the four auger grease fittings (M,
Figure 5-5) using a grease gun. Rotate
auger three or four times. Reinstall
shear bolts, torque to 11 ft-lbs
(15Nm).

9. Check the auger gear case oil level :

a. Place the unit on a smooth, level

surface. Unscrew the plug
(N, Figure 5-5) from the front of
the gear case.

b. Inspect plug hole. Oil should just

begin to seep out of the hole. Add
SAE 90 gear oil if necessary until
oil just begins to flow out of hole.
Let the excess oil drain out of the
gear case.

c. Reinstall the plug (N).

10. Remove bolts (O, Figure 5-4) securing
bottom cover to unit. Remove bottom
cover. Put gear shift lever in highest
speed setting and apply a coating of
multi-purpose grease to the shafts (P
and R, Figure 5-2). Prevent grease
from contacting rubber drive wheel (S)
or drive disk (T). If grease should con­tact these parts, wipe clean to avoid
slippage and assure proper operation.
Move shift lever between high speed
and reverse settings to spread grease
along shafts. Replace bottom cover.

WHEEL DRIVE DISC
ADJUSTMENT

Due to wear, the wheel drive control disc
may begin to slip when wheel drive lever is

engaged. To adjust wheel drive disc:

1. With the engine stopped and the spark
plug wire disconnected, pull the wheel
drive control arm (V, Figure 5-4) down
completely.

2. Put the gear shift lever (AC, Figure 5-

SHEAR BOLTS

Special shear bolts (L, Figure 5-5) secure
the augers to the auger shaft and are de­signed to break (shear) if the auger jams.
This prevents damage to other, more vital
parts. Inspect shear bolts before each use
and replace them if they are worn or bro­ken. Torque shear bolts to 11 ft-lbs
(15 Nm).

AUGER DRIVE BELT(S)
ADJUSTMENT

Due to wear, the auger drive belt(s) may
begin to slip when the auger drive lever is
engaged. To adjust the auger drive belt(s):

1. Perform the brake arm adjustment as

described in this section. Leave the
spark plug wire disconnected while per­forming this adjustment.

2. If assembling a new unit, raise the

wheel drive control lever (AP, Figure
5-7) and the auger drive control lever
(AL).

3. Pull the auger drive control arm (AJ,

Figure 5-8) down completely.

4. Measure and note distance between

coiled ends of spring (AK, Figure 5-8).

5. Squeeze auger drive control lever (AL,

Figure 5-7) against handlebar. Measure
between the coiled ends of the
stretched spring (AK, Figure 5-8), mak­ing sure you measure between the
same coils used in step 4.

The spring length should now measure
9/16" – 11/16" (14–17mm) longer than the
measurement taken in Step 4. If it does
not, loosen the jam nut (AM, Figure 5-8)
and turn the adjuster (AN) to increase or
decrease the length of the spring. Hold
the adjuster and tighten the jam nut (AM)
when the correct spring length is ob­tained. Re-check the measurements and
adjust if needed.

NOTE: 1-1/4 turns of the adjuster equals
1/16" (1.5mm) of spring extension.

GEAR SHIFT ROD ADJUSTMENT

1. With the engine stopped and the spark
plug wire disconnected, move the gear
shift lever (AU, Figure 5-7) to position
No. 5. Remove the hairpin cotter and
the flat washer from the pivot block (N,
Figure 5-10). Disconnect the pivot
block (N) from the gear shift lever plate
(AV, Figure 5-10).

2. Pull the gear shift control rod (AA,
Figure 5-8) down completely.

3. While holding the gear shift control rod
(AA, Figure 5-8) down, loosen the jam
nut (ZZ, Figure 5-10) and thread the
pivot block (N) up or down as needed
so it fits into the hole in the gear shift
lever plate (AV, Figure 5-10).

4. Reinstall the pivot block (N, Figure 5-

10) into the gear shift control lever hole
and secure with the washer and hairpin
cotter. Secure the jam nut (ZZ, Figure
5-10) against the pivot block (N).

5. Move the gear shift control lever (AU,
Figure 5-7) through the full range of
travel. Check for binding. Refer to the

Drive Disc Clearance Adjustment

instructions, if needed.

DRIVE DISC CLEARANCE
ADJUSTMENT

If the gear shift rod lever does not move
freely through all the gear positions, ad­just clearance (AY, Figure 5-9) as follows:

1. With the engine stopped and the spark
plug wire disconnected, loosen jam nut
(AW, Figure 5-8). Rotate adjusting
screw (AX) until rubber drive wheel (T,
Figure 5-9) contacts metal drive disc
(U).

2. Turn the rubber drive wheel (T, Figure
5-9) and the metal drive disc (U) to
find the point of minimum clearance
(AY). (This is where both the drive
wheel [T] and metal disc [U] are
touching.)

3. Adjust the discs at the point of mini­mum clearance. Loosen adjusting
screw (AX, Figure 5-8) 1/2 turn.
Secure the adjusting screw (AX) in
place, while tightening the jam nut
(AW).

4. Check the clearance (AY, Figure 5-9)
by moving gear shift lever (AU, Figure
5-7) through all positions. Repeat
Step 3 as necessary.

BRAKE ARM ADJUSTMENT

The brake arm adjustment is set at the
factory to 1/16 - 1/8" for proper belt/brake
clearance. Due to wear, this may need
adjustment.

WARNING

Section 5: Maintenance

To adjust brake arm:

1. With engine stopped and spark plug
wire disconnected, remove screws and
washers (AB, Figure 5-1) and remove
belt cover from unit.

2. Squeeze the auger drive control lever
(AL, Figure 5-7) against handlebar.

3. Using a flashlight, look down through
the pulleys and belts (Figure 5-6).
Check gap between brake arm (A,
Figure 5-11) and belt (B). The gap
should measure between 1/16" and
1/8" (1.5–3 mm).

4. To adjust gap: Loosen nut (C, Figure
5-11). Hold bolt (D) in place and rotate
nut (E) until proper clearance is ob­tained. Secure nut (C).

5. Reinstall the belt cover.

SKID SHOES/SCRAPER BLADE

The unit should be adjusted so the collec­tor (auger/impeller) housing and the
scraper blade (N, Figure 5-12) are 1/8" (3
mm) above the surface to be cleared. If
the unit is used to clear gravel or uneven
surfaces, this adjustment should be in­creased so gravel or other foreign objects
are not scooped into the auger. To adjust
the collector housing/scraper blade height:

1. Move the unit onto a level surface.

2. With the engine stopped and the spark
plug wire disconnected, loosen the
hardware securing the skid shoes (M,
Figure 5-12).

3. Adjust skid shoes until they are in the
correct position to support collector
(auger/impeller) housing and scraper

blade (adjust both skid shoes equally
to prevent uneven snow removal).

4. Tighten the hardware to lock the
skid shoes (M, Figure 5-12) into the
proper position.

5. The scraper blade (N, Figure 5-12) can
also be adjusted. Adjust scraper blade
(N) at carriage bolts. Adjust bottom
edge of scraper blade so it is parallel
with bottom edge of auger.

SLIP DIFFERENTIAL
ADJUSTMENT

1. With the engine stopped and the spark
plug wire disconnected, remove hub
cap (AQ, Figure 5-13) at end of wheel
shaft on right side of unit.

2. Remove outer (AR, Figure 5-13) and
inner jam nuts (AS) and both pairs
(four single disc springs) of disc
springs (AT). Inspect springs and re­place them if they are worn.

3. Reinstall disc springs (AT, Figure 5-

13) and inner jam nut (AS). Tighten
jam nut (AS) by hand until it contacts
the disc spring, then tighten (AS) 1 to
1-1/4 turns more. DO NOT force nut
more than 1-1/4 turns or differential
will not work (unit will be difficult to
turn).

4. Secure the inner nut (AS, Figure 5-13)
in place, while tightening the outer nut
(AR).

5. Reinstall cover (AQ, Figure 5-13).
