To Start Engine

Attach spark plug wire to spark plug. Make certain 
the metal loop on end of the spark plug wire (inside 
the boot) is fastened securely over the metal tip on 
the spark plug.

Make certain the auger and drive clutch levers are 
in the disengaged (released) position.

Move throttle control up to FAST position. Insert 
ignition key into slot. See Figure 5. Be certain it 
snaps into place. Do not turn key. 

NOTE:  Engine will not start unless ignition key is
inserted into ignition slot in carburetor cover. 

Electric Starter

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.

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.

If your home electrical system is grounded, but a 
three-hole receptacle is not available, one should 
be installed by a licensed electrician before using 
the electric starter.

If you have a grounded three-prong receptacle, 
proceed as follows:

Rotate choke knob to OFF position and do not 
prime engine.

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 on top of the engine to crank 
engine. As you crank the engine, move choke knob 
to FULL choke position.

When engine starts, release starter button, and 
move choke gradually to OFF. If engine falters, 
move choke immediately to FULL and then 
gradually to OFF.

When disconnecting the power cord, always unplug 
from the three-prong receptacle first and then from 
the snow thrower.

Recoil Starter

Rotate choke knob to FULL choke position (cold 
engine start). If engine is warm, place choke in OFF 
position instead of FULL.

Push primer button two or three times. If engine is 
warm, push primer button once only.

NOTE:  Always cover vent hole in primer button when
pushing. Additional priming may be necessary for first
start if temperature is below 15°F.

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 the starter handle.

Repeat the previous steps until engine starts.

To Stop Engine

Run engine for a few minutes before stopping to 
help dry off any moisture on the engine.

To help prevent 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 starter.

To stop engine, move throttle control to “stop” or 
“off” position.

Remove ignition key. Do not turn key.

Disconnect the spark plug wire from the spark plug 
to prevent accidental starting while equipment is 
unattended.

NOTE: Do not lose ignition key. Keep it in a safe place.
Engine will not start without ignition key.

Wipe all snow and moisture from the carburetor 
cover in the area of the control levers. Also, move 
control levers back and forth several times.

To Engage Track Drive

With the engine running near top speed, move the 
shift lever into one of the six FORWARD positions 
or two REVERSE positions. Select a speed 
appropriate for the snow conditions that exist. 

Squeeze the auger control grip and the augers will 
turn. Release it and the augers will stop.

Squeeze traction control grip and the snow thrower 
will move. Release it and drive motion will stop.

NEVER move shift lever without releasing drive 
clutch.
