4.6 AUGER GEARCASE
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.
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 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).
4.7 ENGINE
Cooling
The engine is air cooled. Air must circulate freely
around engine from Air Intake to cooling fins on
cylinder head and block, to prevent overheating.
Each year (more often if conditions require) remove
cooling shrouds and clean cooling fins. Clean external
surfaces of engine of dust, dirt, and oil deposits which
can contribute to improper cooling. See Engine
Manual.
IMPORTANT:
DO NOT operate engine with cooling
shrouds removed. Engine overheating and damage will
result.
Engine Oil Check
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).
To check, park unit on a flat, level surface and:
1. Clean all debris away from oil cap.
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.
4. Replace dipstick and cap. Clean up any spilled oil.
Engine Oil Change
Change oil after first 5 hours of operation, thereafter
change oil every 25 hours (more often if required).
NOTE:
Run engine just prior to changing oil. Warm oil
will flow more freely and carry away more contamina-
tion.
1. Drain crankcase by removing oil drain plug (see
Engine Manual).
2. When oil has drained replace plug and refill engine
crankcase with new oil of proper grade.
3. Recheck oil level with dipstick.
