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 con-
ditions. If your system is grounded and a three-hole
receptacle is not available at the point your 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
the end from the three-hole grounded receptacle first.
1. Rotate choke knob to OFF position. Do not
prime engine.
2. Connect power cord to switch box on engine.
Plug the other end of power cord into a three-
hole, grounded 12-volt AC receptacle.
3. Push starter button to crank engine. As you crank
the engine, move choke knob to FULL choke
position. (cold engine start) See Figure 12.
4. When engine starts, release starter button, and
move choke gradually to OFF. If engine falters,
move choke immediately to FULL and then grad-
ually to OFF.
TO STOP ENGINE
1. Run engine for a few minutes before stopping to
help dry off any moisture on the engine.
2. To help prevent possible freeze up of starter, pro-
ceed 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.
3. To stop engine, move throttle control to STOP or
OFF position.
4. Remove the ignition key. Do not turn key. Discon-
nect the spark plug wire from the spark plug to
prevent accidental starting while equipment is
unattended.
NOTE: Do not lose the ignition key. Keep it in a
safe place. Engine will not start without the ignition
key.
5. 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 DRIVE
1. With the engine running near top speed, move
shift lever into one of the five FORWARD posi-
tions or two REVERSE positions. Select a speed
appropriate for the snow conditions. Use the
slower speeds until you are familiar with the oper-
ation of the snow thrower.
2. Squeeze the auger control and the augers will
turn. Release it and the augers will stop.
3. Squeeze the traction control and the snow
thrower will move. Release it and drive motion
will stop.
4. NEVER move shift lever without releasing trac-
tion control.
TO ENGAGE AUGERS
To engage the augers and start the snow throwing
action, squeeze the auger control against the left
handle. Release to stop the augers.
TIRE CHAINS (Optional Equipment)
Tire chains should be used whenever extra traction is
needed.
OPERATING TIPS
NOTE: Allow the engine to warm up for a few min-
utes as the engine will not develop full power until it
reaches operating temperature.
WARNING: Temperature of muffler
and surrounding areas may exceed 150
degrees Fahrenheit. Avoid these areas.
1. For most efficient snow removal, remove snow
immediately after it falls.
2. Discharge snow downwind whenever possible.
Slightly overlap each previous path.
3. Set the skid shoes 1/4" below the scraper bar for
normal usage. The skid shoes may be adjusted
upward for hard-packed snow. Adjust downward
when using on gravel or crushed rock.
4. Be certain to follow the precautions listed under
TO STOP ENGINE to prevent possible freeze-up.
5. Clean the snow thrower thoroughly after each
use.
