running to see how it works and what it does.
Manual Start
1. Turn discharge chute straight ahead.
2. Release auger clutch bail.
3. Push Primer Bulb 2 or 3 times for a cold
engine.
NOTE: When temperature is below
-15˚F (-26˚C) additional priming may be
needed.
4. If engine is cold, apply choke. See Engine
Manual for detailed instructions.
NOTE: A warm engine requires less choking
than a cold engine.

performed on a regular basis.
CHECK FASTENERS
Make sure all hardware is tightened properly.
CHECK ATTACHMENT CLUTCH
Auger and impeller must stop quickly when
attachment clutch lever is released.
If clutch does not engage or disengage
properly, adjust or repair before operation (see
Service and Adjustments).
CLEAN ENGINE
Refer to Engine Manual for detailed
instructions.
CHECK ENGINE OIL
The engine crankcase oil should be checked
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).
Park unit on a level surface. Refer to Engine
Manual for detailed instructions.
CHANGE ENGINE OIL
Change oil after first two (2) hours of
operation, thereafter change oil every 25
hours (more often if required). Refer to Engine
Manual for detailed instructions.
NOTE: Snow thrower has an oil drain cut-out
on the left side of unit frame. Drain engine oil
through this cut-out to prevent spills.
CHECK TIRE PRESSURE
Keep tires at pressure listed on the tire
sidewall.
CHECK AUGER GEARCASE
IMPORTANT: Proper oil level must be
maintained.
Gear cases are filled to the correct level at the
factory. Unless there is evidence of leakage,
no additional lubricant should be required.
Check oil level each season or every 25 hours
of operation.
To ensure adequate lubricant level:
1. Remove filler plug (Figure 5). 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.
IMPORTANT: Use only Ariens special gear
lubricant L-2 (Part Number 00008000).
GENERAL LUBRICATION
IMPORTANT: Wipe each fitting clean before
and after lubrication.
IMPORTANT: DO NOT allow grease or oil to
get on belts.
NOTE: Apply Sten Mix Hi-Temp Grease or
equivalent to the lubrication fittings.
Snow thrower should be lubricated at
beginning of season or every 25 operating
hours (Figure 6).
Auger Shaft
To grease auger shaft, remove shear bolt nuts
and shear bolts. Turn auger on shaft while
applying grease at zerk fittings. Replace shear
bolts.

ATTACHMENT CLUTCH / BRAKE
ADJUSTMENT
IMPORTANT: AUGER/IMPELLER MUST
STOP within 3 seconds when attachment
clutch bail is released.
1. Remove belt cover.
2. Check belt alignment (Figure 9).
Engine sheave and attachment pulley
must align vertically. Also, belt must be
centered in the idler pulley.
To move pulley or sheave:
a.Loosen set screw.
b.Slide pulley/sheave and key to desired
position.
c.Tighten set screw.
3. Adjust cable slack.
The clutch cable must be slack when the
bail is disengaged.
a.With clutch bail disengaged, loosen
jam nut on cable adjuster.
b.Lift spring arm, but do not move idler
arm.
c.Turn adjuster body to remove all slack
from the cable. Do not stretch spring
or move idler arm.
d.Release spring arm and turn back the
adjuster body 5 turns (approximately
1/4”or 6mm). Finger tighten jam nut.
e.Hold adjuster body with pliers and
tighten jam nut with wrench.
4. Check spring length.
a.Measure the length of the clutch cable
spring.
b.Engage and hold the attachment
clutch bail.
c.Measure the length of the spring
again.The spring should be 1/8”- 3/16”
(3-5mm) longer when the bail is
engaged.
5. Adjust spring length.
a.Loosen the idler adjustment nut.
b.To increase spring extension, move
idler towards belt (Figure 7).
c.To decrease spring extension, move
idler away from belt.
d.Tighten idler adjustment nut.
6. Check brake.
When the clutch bail is disengaged, the
brake must contact attachment belt.
When the clutch bail is engaged, the
brake must be more than 1/16”(2mm)
away from the belt.
7. Repeat steps 4 –6 until:
Spring stretch and brake contact are
correct.
8. Check belt finger clearance.
With clutch bail engaged, belt fingers
should be 1/16”–1/8”(2–3mm) from belt.
Adjust belt fingers as necessary.
9. Replace belt cover.
WARNING: IMPROPER
ADJUSTMENT could result in
unexpected movement of auger
and impeller causing death or
serious injury.

DISCHARGE CHUTE
If Chute does not stay in position while
operating, tighten nut on carriage bolt at pivot
point to increase tension on spring (Figure 10).
If the deflector cap does not remain set in
position tighten nut on right side of cap until
proper drag is obtained.
SHEAR BOLTS
IMPORTANT: Use only Ariens shear bolts for
replacement. Use of any other type of shear
bolt may result in severe damage to unit.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger,
breaking shear bolts (Figure 11) which secure
the auger to the shaft. This allows auger to
turn freely on the shaft preventing damage to
gear drive.
For Replacement:
1. Slide auger outward and align hole in
shaft with hole in auger.
2. Drive shear bolt through hole (if shear bolt
was broken this will drive remaining part
from shaft).
3. Secure shear bolt with nut.
AUGER EDGE REPLACEMENT
Over time the rubber edges of the auger will
wear. Contact your Ariens Dealer for
replacement.
IMPORTANT: Replace rubber edges before
metal auger begins to wear.
NOTE: After replacement of auger rubber
edges, adjust scraper blade. See Scraper
Blade Adjustment below.
SCRAPER BLADE ADJUSTMENT
IMPORTANT: Damage to auger/impeller
housing will result if blade wears down too far.
Scraper blade is adjustable to compensate for
wear.
To adjust scraper blade:
1. Tip unit back onto handlebar, support
housing and loosen nuts retaining blade.
2. If unit does not scrape cleanly, move
scraper blade forward. If unit does not
drive forward and scraper blade drags,
move scraper blade to the rear.
Tighten hardware and test unit. Repeat
adjustment as required until proper operation
is obtained.
