4.7 MAINTENANCE SCHEDULE
The chart below shows the recommended
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 and 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 18 or “Traction Drive
Clutch Adjustment” on page 19).
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 18 or
“Traction Drive Clutch Adjustment” on page 19
Clean Engine
Refer to Engine Manual for detailed instructions.
Check Engine Oil
Check engine crankcase oil 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 a few minutes just before changing oil.
Warm oil will flow more freely and carry away more
contamination. Place a suitable container under the oil
drain plug. 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 Gear Case
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). Gear case 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 gear case filler plug; wiping the
gear case filler plug may remove thread sealant and
cause leaks.
IMPORTANT: DO NOT allow grease or oil to get on the
belts.
NOTE: Apply Ariens Hi-Temp Grease or equivalent to
the lubrication fittings. See
“Service Parts List” on
page 32.
Lubricate Sno-Thro at the beginning of the season or
every 25 operating hours, whichever comes first.
