Maintenance
POTENTIAL HAZARD
If you leave the wire on the spark plug,
someone could start the engine.
WHAT CAN HAPPEN
Accidental starting of engine could
seriously injure you or other bystanders.
HOW TO AVOID THE HAZARD
Pull wire off spark plug and remove key
from switch before you do any
maintenance. Also push wire aside so it
does not accidentally contact spark plug.
Draining Gasoline
1.
Close fuel shut–off valve located under fuel tank
(Fig. 19) by rotating valve to the left.
POTENTIAL HAZARD
Gasoline is highly flammable.
WHAT CAN HAPPEN
Gasoline can be ignited and cause serious
personal injury.
HOW TO AVOID THE HAZARD
Drain gasoline outdoors.
Drain gasoline from a cold engine only.
Wipe up any gasoline that may have
spilled.
Do not drain gasoline near any open flame
or where gasoline fumes may be ignited by
a spark.
DO NOT SMOKE a cigar, cigarette or pipe
when handling gasoline.
2.
Place a clean drain pan under shut–off valve.
GB–19
3.
Loosen hose clamp securing fuel line to valve
and slide line off valve (Fig. 19).
4.
Open valve by rotating valve to the right. This
allows fuel to flow into drain pan.
5.
Reinstall fuel line and secure with hose clamp.
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. 16).
2.
Drain gasoline from fuel tank; refer to Draining
Gasoline, page 19.
3.
Tip snowthrower forward onto auger/impeller
housing and block it so it cannot fall. Now,
remove four screws holding bottom cover in
place and remove cover (Fig. 20).
4.
Lightly lubricate snowthrower with light oil and
grease as shown in Figure 21. Wipe up any
excess oil or 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.
5.
Reinstall bottom cover with (4) 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.
