SECTION 2 - SAFETY
2.1 SAFETY ALERTS
2.6 PREPARATION
Look for these symbols to point out
important safety precautions. They
mean:
Before starting any removal of parts, proper
preparation is very important for efficient work. A clean
work area at the start of each job will allow you to
perform service repairs easily and quickly.
Attention!
Personal Safety Is Involved!
Become Alert!
Obey The Message!
To reduce the incidence of misplaced tools or parts,
place removed components with all attaching hardware
in the disassembly order on a clean work surface.
Organization is a key part of proper reassembly.
Tools, instruments, and parts needed for the job should
be gathered before work is started. Interrupting a job to
locate tools or parts is a needless delay. A list of
required special tools has been included in this
manual.
2.2 SIGNAL WORDS
The safety alert symbol is used in decals on the unit
and with proper operation procedures in this manual.
They alert you to the existence and relative degree of
hazards.
2.7 SERVICE POSITION

information about personal safety on or near the unit.
WARNING: ALWAYS block wheels and know
that jack stands or blocks used are stable,
strong, secure and will hold the weight of the
unit during maintenance.
DANGER: IMMINENTLY HAZARDOUS
SITUATION! If not avoided, WILL RESULT in
death or serious injury.
To ensure the unit is positioned in the proper service
position place unit on a flat level surface. ALWAYS stop

4.6 AUGER GEARCASE
Engine Oil Check
IMPORTANT: Too much lubricant may cause
excessive leakage. Too little lubricant will cause gear
and/or bearing damage. Proper oil level must be
maintained for operation.
The engine crankcase oil should be checked daily or
every 5 hours of operation. Oil level MUST be
maintained in safe operating range on dipstick at all
times or engine damage will result (See Engine
Manual).
Gear cases are filled to the correct level at the factory.
Unless there is evidence of leakage, no additional
lubricant should be required. Check for evidence of
leakage every 25 hours or operation.
To check, park unit on a flat, level surface and:
1. Clean all debris away from oil cap.
To ensure adequate lubricant level:
1. Remove filler plug. Lubricant must be at least up to
bottom of lubricant filler hole with unit resting on a
level-surface.
2. Add lubricant, if required, allow oil to drain to level
of plug and replace plug (Figure 4).
3. Use only Ariens special gear lubricant L-2
(P/N 00008000).
2. Remove oil cap and dipstick. Wipe oil of dipstick
with a clean cloth. Replace dipstick until cap
bottoms on tube. Remove dipstick again and
observe oil level. Oil should be at the Full (F) mark.
3. If low, add oil and bring up to the Full (F) mark.
IMPORTANT: DO NOT over fill. Oil level must not
exceed Full (F) mark.

IMPORTANT: Use only Ariens Shear Bolts for
replacement. Use of any other type of shear bolt may
result in severe damage to the unit.
4.11 TIRE PRESSURE
Occasionally a foreign object may enter the auger/
impeller housing and jam the auger, breaking shear
bolts which secure the auger to the shaft (Figure 7).
This allows auger to turn freely on the shaft preventing
damage to the gear drive.
Maintain the unit tire pressure at a maximum of
20 PSI (138 kPa).
4.12 ADJUSTMENTS
WARNING: ACCIDENTAL ENGINE START
UP can cause death or serious injury.

Attachment Clutch/Impeller Brake
WARNING: AUGER/IMPELLER MUST STOP
within 5 seconds when attachment clutch/
impeller brake lever is released or unit
damage or serious injury may result.
ROTATING PARTS can cut off body parts.
Keep hands and feet away. Loose clothing,
long hair or scarves can get caught in rotating
parts and cause death or serious injury.
It is necessary to perform the adjustments
with the belt guard removed and extreme care
is to be taken to prevent injury. Stand well
clear of the open belt drive while engine is
running.
IMPROPER ADJUSTMENT could result in
death or serious injury.
IMPELLER BRAKE MUST DISENGAGE
when clutch is engaged. Brake must be 1/16"
(1.6 mm) minimum from belt when
disengaged.
BELT FINGERS MUST BE between 1/16 to
1/8" (1.6 - 3.2 mm ) from belt with attachment
clutch engaged or belt grabbing may occur
causing impeller to rotate while attachment
clutch is disengaged.
There MUST BE a slight amount of slack in
cable or impeller may rotate while attachment
clutch is disengaged.
3. Measure distance between impeller brake shoe
pad and belt with attachment clutch engaged
(Figure 10). Impeller brake shoe should be 1/16"
(1.6 mm) minimum from belt. When attachment
clutch is disengaged, brake must contact belt.
To properly adjust attachment clutch/impeller brake:
1. Without the engine running, remove the belt cover.
Attachment brake is seated against the attachment
drive belt when the attachment clutch lever is in the
released (full up) position. Adjust the control cable
mounting nuts to snug up the control cable, then
back off on the top nut 2 turns to provide cable
slack for brake wear. Tighten bottom nut.
2. Start engine and run at full throttle. Slowly depress
the attachment clutch lever until the auger shaft
begins to rotate, observing the bolt at the end of
the auger shaft. The measurement between the
end of the attachment clutch lever and the handle
grip at this point should be between 3" and 3-1/4"
(7.62 - 8.25 cm) as shown in Figure 11. If this
dimension is not within this range shut off the
engine and adjust the attachment drive idler pulley
as required. A 1/16" (1.6 mm) adjustment of the
attachment drive idler pulley will result in an
approximate 1/4" (6.35 mm) change in the
attachment clutch control lever engagement
position. Moving the attachment drive idler pulley
toward the attachment drive belt will increase the
dimension between the attachment clutch control
lever and the handle grip.
3. Restart the engine and recheck the 3" - 3-1/4"
(7.62 - 8.25 cm) dimension.
4. Shut off the engine and install the belt guard.

Occasionally an object may enter auger/impeller
housing and jam auger, breaking shear bolts which
secures auger to shaft. This allows auger to turn freely
on shaft preventing damage to gear drive.
To replace shear bolt:
1. Slide auger outward against roll pin and align hole
in shaft with hole in auger (Figure 20) (holes in
shaft for roll pins and shear bolts line up).
9.2 SCRAPER BLADE
IMPORTANT: If blade wears too far auger/impeller
housing may be damaged.
2. Drive the new shear bolt through hole (if shear bolt
was broken this will drive remaining part from
shaft).
Scraper blade is adjustable to compensate for wear.
To adjust scraper blade:

9.5 RUNNERS
raise runners so that scraper blade scrapes clean. To
reduce tendency of housing to ride up over heavy wet
or hard-packed snow, remove runners and re-install
with the narrow edge down.
CAUTION: Adjust auger/impeller housing
height to clear gravel or crushed rock
surfaces.
Runners should be adjusted as conditions require
(Figure 22). Raising or lowering runners controls
distance scraper blade is held above surface being
cleared.
When operating machine on gravel surface, lower
runners so that housing will not pick up gravel. On
concrete, blacktopped or packed down snow surfaces,
Position unit on a flat level surface. Adjust runners by
inserting a spacer of desired thickness under center of
scraper blade, loosen hardware, slide runners to flat
surface and retighten hardware.
NOTE: Above method keeps housing level by adjusting runners equally. Uneven runners make machine
difficult to steer and results in uneven clearing.

SECTION 10 - GEAR CASE
10.1 ALUMINUM GEAR CASE
8. Behind rear bronze bushing is a seal which fits into
a groove in gearcase. It should be replaced at time
of repair.
1. Remove auger/impeller and gear case from
housing referring to Auger/Impeller Section.
2. Remove six bolts that hold right and left gear case
halves together (Figure 23).
3. If flange bushings need replacement, first remove
seals from outside of gearcase halves with a
screwdriver. Flange bushings can then be pressed
out from outside in with a bearing driver. Bushings
are very lightly pressed in.
4. When replacing bushings make sure the flat on the
flange of bushing fits in the inside notch of the
case.
9. Rear bushing is a larger diameter than one in front,
but are identical in design. Replace if necessary.
10.If replacement of thrust collar is necessary, again
drive out groove pin towards direction of least
resistance.
11.Inspect worm for burrs or black coloration. If either
show up, replace shaft.
12.For re-assembly, replace the gasket with P/N
00031700 (use Loctite 518 provided). Make sure
the flats on the bushings are in their proper place.
This case requires Ariens L-2 P/N 00008000 and
should be half full.
5. There are two special washers, one on either side
of bronze gear. If burred or worn they should be
replaced.
6. Holding bronze gear on rake shaft is a groove pin.
When driving out, drive in direction of least
resistance. the flat on bronze gear face will fill the
hole in the side of the gearcase.
7. Remove bronze bushing from front of worm shaft
by sliding it off. Replace if necessary. Notice that a
flat on the bushing flange positions the bearing
inside the gearcase.
After assembly is complete you should be able to turn
input shaft freely.
Auger/impeller gearcase is lubricated with Ariens L-2
(P/N 00008000). Check lubrication by removing filler
plug. Lubrication should be even with hole with unit
sitting level. It may be necessary to insert a wire into
the hole to check level. Unit will not be damaged by
over-lubricating.
