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:
• Connect power cord to switch box on engine. Plug
the other end of power cord into a three-prong, 120-
volt, grounded, AC receptacle.
• Rotate choke knob to ON or FULL choke position
(cold engine start). If engine is warm, place choke
in OFF position instead of FULL.
• Push primer button three times for cold engine
start, making sure to cover vent hole in primer
button when pushing. DO NOT use primer to restart
a warm engine after a short shutdown.
• Push starter button to start engine.
• When engine starts, release starter button, and
move choke gradually to OFF. If engine falters,
move choke immediately to ON or 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 ON or FULL choke position
(cold engine start). If engine is warm, place choke
in OFF position instead of ON or FULL.
• Push primer button three times for cold engine
start. DO NOT use primer to restart a warm engine
after a short shutdown.
NOTE: Always cover vent hole in primer button when
pushing. Additional priming may be necessary for first
start if temperature is below 15°F (-9°C).
• 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.
• As engine warms up, 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 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.
• Move throttle control to “stop” or “off” position.
• Remove ignition key (DO NOT turn key) to prevent
unauthorized use of equipment.
• 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 Drive
• With the engine running near top speed, move shift
lever to one of the eight positions to set desired
speed and direction. Select speed appropriate for
the snow conditions that exist.
NOTE: Use slower speeds in higher snow and/or until
you are familiar with the snow thrower operation.
• Squeeze drive control against the right handle to
move the snow thrower; release it to stop.
IMPORTANT: NEVER move the shift lever without first
releasing the drive control. Doing so will cause
premature wear on the drive system’s friction wheel.
To Engage Augers
• To engage augers and start snow throwing,
squeeze the auger control against the left handle.
• To disengage power to the augers, release both the
auger control and the drive control, if engaged.
NOTE: The drive control also locks the auger control so
you can turn the chute directional control without
interrupting the snow throwing process. If the auger
control is engaged simultaneously with the drive
control, the operator can release the auger control (on
the left handle) and the augers will remain engaged.
Release both controls to stop the augers and track
drive.
