SECTION 4: OPERATING YOUR SNOW THROWER
Gas and Oil Fill-up
Service the engine with gasoline and oil as instructed in
the separate engine manual packed with your snow
thrower. Read instructions carefully.
WARNING: Never fill fuel tank indoors,
with engine running or while engine is hot.
Do not smoke when filling up a fuel tank.
Tire Pressure
Tires are over-inflated for shipping purposes.
Reduce the tire pressure to 10-15 p.s.i. for
snowthrower operation. Use pneumatic tires only
on your snowthrower unit.
Tire chains (optional equipment) should be used
whenever extra traction is needed.
Electric Starter
WARNING: The electric starter is
equipped with a three-wire power cord
and three-prong plug, and is designed to
operate on 120 volt AC household current.
It must be properly grounded at all times
to avoid possibility of electric shock
which may be injurious to the operator.
Follow all instructions carefully.
Determine that your house wiring is a
three-wire grounded system. Ask a
licensed electrician if you are not certain.
If your house wiring system is not a three-
wire grounded system, do not use this
electric starter under any conditions. If
your house wiring system is grounded but
a three-hole receptacle is not available at
the point the starter will normally be used,
one should be installed by a licensed
electrician.
When connecting the power cord, always connect
cord to starter on engine first, then plug the other
end into a three-hole grounded receptacle.
When disconnecting the power cord, always unplug
from the three-hole grounded receptacle first.
To Start Engine
IMPORTANT:
If unit shows any sign of motion (drive or
augers) with the clutch grips disengaged, shut engine
off immediately. Readjust as instructed in the Final
Adjustments section of the Set-Up Instructions.
Attach spark plug wire to spark plug. Make certain
that the metal loop on the end of the spark plug wire
(inside the boot) is fastened securely over the metal
tip on the spark plug.
Make certain the fuel shut-off valve, if equipped, is
in the open (vertical) position.
Make certain the auger and drive clutch levers are
in the disengaged (released) position.
Move throttle control to FAST position.
Insert ignition key into slot. Make sure it snaps into
place. Do not turn key.
Follow next three steps for electric start only.
Rotate choke knob to OFF position.
Connect power cord to switch box on engine. Plug
the other end of power cord into a three-hole,
grounded 120 volt AC receptacle.
Push starter button to crank the engine. When
engine starts, release the starter button, and move
choke gradually to FULL, and then to OFF position.
If the engine falters, move choke immediately to
FULL position and then gradually move it to OFF
position.
Follow the next four steps for recoil start only:
Rotate choke knob to FULL position. If engine is
already warm, place choke in OFF position instead
of FULL position.
Push primer button two or three times. If engine is
warm, push primer button once only.
Grasp starter handle and pull rope out slowly, until
it pulls slightly harder. Let rope rewind slowly. Pull
starter handle rapidly. Do not allow handle to snap
back. Allow it to rewind slowly while keeping a firm
hold on starter handle. Repeat until engine starts.
As engine warms up and begins to operate evenly,
rotate choke knob slowly to OFF position. If engine
falters, return to FULL choke, then slowly move to
OFF position.
To Stop Engine
Run engine for a few minutes before stopping to
help dry off any moisture on the engine.
To avoid possible freeze-up of starter, proceed as
follows.
Electric Starter: Connect power cord to switch
box on engine, then to 120 volt AC receptacle. With
the engine running, push starter button and spin
the starter for several seconds. The unusual sound
made by spinning the starter will not harm engine
or starter. Disconnect the power cord from
receptacle first, and then from switch box.
Recoil Starter: With engine running, pull starter
rope with a rapid, continuous full arm stroke three
or four times. Pulling the starter rope will produce a
loud clattering sound, which is not harmful to the
engine or the starter.
To stop engine, push the throttle lever all the way
down, or remove the ignition key. Do not turn key.
