maintenance schedule that should be performed on a
regular basis. More frequent service may be required.
*
After first five hours of operation.
**
After first two hours of operation.
CHECK FASTENERS
Make sure all hardware is tightened properly.
CHECK CLUTCH OPERATION
Auger / impeller must stop within 3 seconds when
attachment clutch/impeller brake lever is released.
Wheels must stop quickly when traction drive clutch
lever is released.
If clutches do not engage or disengage properly, adjust
or repair before operation (see Attachment
Clutch/Brake Adjustment on page 16 or Traction Drive
Clutch Adjustment on page 17).
CHECK CLUTCH SPRING ADJUSTMENT
Make sure the attachment clutch and traction drive
clutch are adjusted to the range specified in
Attachment Clutch/Brake Adjustment on page 16 or
Traction Drive Clutch Adjustment on page 17.
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 2 hours of operation, thereafter
change oil every 25 hours (more often if required).
Refer to Engine Manual for detailed instructions.
Run engine just prior to changing oil. Warm oil will flow
more freely and carry away more contamination.
Remove the oil drain plug from the rear of the unit and
tip the unit back to help drain all the oil.
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 9). 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). Gearcase filler plug may
require an application of Loc-Tite® 565 thread sealant
with repeated servicing.
GENERAL LUBRICATION
IMPORTANT: Wipe each fitting clean before and after
lubrication. Do not wipe gearcase filler plug; wiping the
gearcase filler plug may remove thread sealant and
cause leaks.
