Starting the Engine
WARNING: Always keep hands and
feet clear of moving parts. Do not use
a pressurized starting fluid. Vapors are
flammable.
NOTE: Allow the engine to warm up for a few minutes
after starting. The engine will not develop full power until
it reaches operating temperatures.
Engines with Starter Handle (non-electric
start)
IMPORTANT: Do not pull the starter handle with engine
running.
Insert ignition key fully into slot. Make sure it snaps 1.
into place. DO NOT turn ignition key. The engine
cannot start unless the key is inserted into ignition
switch.
Move throttle control to FAST (rabbit) position.
2.
Move choke to the ON position (cold engine start). If 3.
engine is warm, place choke in OFF position.
Push primer three to five (3-5) times, making sure
4.
to cover vent hole when pushing. If engine is warm,
push primer only once. Always cover vent hole when

control to OFF position. If the engine falters, restart
engine and run with choke at half-choke position
for a short period of time, and then slowly rotate the
choke into OFF position.
Engines with Electric Starters
WARNING: The electric starter is
equipped with a grounded three-wire
power cord and plug, and is designed
to operate on 120 volt AC household
current. It must be used with a properly
grounded three-prong receptacle at all
times to avoid the possibility of electric
shock. Follow all instructions carefully
prior to operating the electric starter.
WARNING: DO NOT use electric starter
in rain.
Determine that your home’s wiring is a three-wire 1.
grounded system. Ask a licensed electrician if you
are unsure. If you have a grounded three-prong
receptacle, proceed as follows. If you do not have the
proper house wiring, DO NOT use the electric starter
under any conditions.
Insert ignition key fully into slot. Make sure it snaps
2.
into place. DO NOT turn ignition key. The engine
cannot start unless the key is inserted into
ignition switch.
Plug the extension cord into the electric switch
3.
box located on the engine. Plug the other end of
extension cord into a three-prong 120-volt, grounded,
AC outlet in a well-ventilated area.
Move throttle control to FAST (rabbit) position.
4.
Move choke to the ON position (cold engine start). If 5.
engine is warm, place choke in OFF position.
Push primer three to five (3-5) times, making sure
6.
to cover vent hole when pushing. If engine is warm,
push primer only once. Always cover vent hole when
pushing. Cool weather may require priming to be
repeated.
Push starter button to start engine.
7. Once the engine
starts, immediately release starter button. Electric
starter is equipped with thermal overload protection;
system will temporarily shut-down to allow starter to
cool if electric starter becomes overloaded.
As the engine warms, slowly rotate the choke control
8.
to OFF position. If the engine falters, restart engine
and run with choke at half-choke position for a short
period of time, and then slowly rotate the choke into
OFF position.
After engine is running, disconnect power cord from
9.
electric starter. When disconnecting, always unplug
the end at the wall outlet before unplugging the
opposite end from the engine.
Stopping the Engine
WARNING: To avoid unsupervised
engine operation, never leave the engine
unattended while running. Turn the
engine off after use and remove ignition
key
Run engine for a few minutes before stopping to help dry
off any moisture on the engine.
Move throttle control to STOP position. 1.
Remove the ignition key. Removing the key will 2.
reduce the possibility of unauthorized starting of the
engine while equipment is not in use.
Keep the key
in a safe place. The engine cannot start without
the ignition key.
Wipe all snow and moisture from the area around the
3.
engine as well as the area in and around the drive
control and auger control. Also, engage and release
both controls several times.
WARNING
Read, understand,
and follow all instruc-
tions and warnings
on the machine and
in this manual before
operating.
Use extreme care
when handling
gasoline. Gasoline is
extremely flammable
and the vapors are
explosive. Never fuel
the machine indoors
or while the engine
is hot or running.
Extinguish cigarettes,
cigars, pipes and
other sources of
ignition.
If your home’s wir-
ing system is not a
three-wire grounded
system, do not use
this electric starter
under any conditions.
If your home
electrical system
is grounded, but a
three-hole receptacle
is not available, do
not use your snow
thrower’s electric
starter.
