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. (see Check Tire Pressure on
page 10).
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 12). 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.
