Lubricating Snowthrower
Lubricate moving parts of the snowthrower after
every 15 hours of operation.
1.
Pull wire off spark plug and make sure wire does
not contact plug accidentally (Fig. 25).
2.
Drain gasoline from fuel tank; refer to Draining
Gasoline, page 16.
3.
Tip snowthrower forward onto auger housing
and block it so it cannot fall. Now, remove (8)
screws holding back and bottom covers in place
and remove covers (Fig. 28).
4.
Lightly lubricate snowthrower with light oil as
shown in Figures 29 and 30. Wipe up any excess
oil.
5.
Lightly grease axle gear (Fig. 29). Wipe up any
excess grease.
IMPORTANT: Do not get oil or grease on
rubber wheel or friction drive plate because
the wheel will slip and the rubber may
deteriorate.
6.
Reinstall back and bottom covers with (8)
screws.
Changing Crankcase Oil
Initially, change oil after the first 2 hours of engine
operation; thereafter, under normal conditions, change
oil after every 25 hours of engine operation or
annually, whichever comes first. If possible, run
engine just before changing oil because warm oil
flows better and carries more contaminants than cold
oil.
1.
Pull wire off spark plug and make sure wire does
not contact plug accidentally (Fig. 25).
2.
Clean area around oil drain plug. Next, slide oil
drain pan below drain extension; then remove oil
drain plug (Fig. 31).
3.
After all oil is drained, reinstall oil drain plug.
4.
Position snowthrower on a level surface. Next,
fill crankcase with oil: refer to Fill Crankcase
With Oil, page 11. Wipe up any oil that may
have spilled.
Auger Gear Box Oil
The auger gear box oil level must be checked at time
of snowthrower assembly, after every 10 hours of use,
and upon removal from annual storage. To check the
auger gear box oil level:
1.
Position snowthrower on a level surface.
2.
Pull wire off spark plug and make sure wire does
not contact plug accidentally (Fig. 25).
3.
Clean area around pipe plug so dirt is removed.
4.
Remove pipe plug from gear box (Fig. 16).
5.
Check level of oil in gear box. Oil must be at
point of overflowing in filler opening.
6.
If level of oil is low, add GL–5 or GL–6 SAE
85–95 EP transmission oil to the gear box until
point of overflow.
Note:
Do not use synthetic gear oil.
7.
Reinstall pipe plug in gear box.
Adjusting Auger/Impeller Drive
Belt
If auger/impeller drive belt slips, resulting in
decreased snowthrowing performance, either an
adjustment or a new belt is required.
After 5-10 hours of snowthrower operation with a
new auger/impeller drive belt, check belt to ensure
proper belt tension is being maintained.
1.
Check adjustment per steps 5–7 of Install
Auger/Impeller Drive Control Linkage, page 9.
Make adjustments if required.
