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-hole,
grounded 120 volt AC receptacle.
Rotate choke knob to FULL position.
Move throttle control to FAST (Rabbit) position.
Fully depress the primer three times, making sure
to cover the vent hole went pushing.
NOTE: Do NOT use the primer when restarting a
warm engine. Doing so will cause the engine to “flood.”
Push starter button on top of the engine.
When engine starts, release starter button, and
move choke gradually to OFF. If engine falters,
move choke momentarily 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.
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.
Move the throttle control to the STOP or OFF
position.
To help prevent starter freeze-up:
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
snow thrower’s 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.
Remove the ignition key. Do not turn key.
Disconnect the spark plug wire from the spark plug
to prevent accidental starting while equipment is
unattended.
NOTE: Keep the ignition key in a safe place. The
engine will not start without the ignition key.
Wipe all the snow and moisture from the carburetor
cover in the area of the control levers. Also, move
the control levers back and forth several times.
To Engage Drive
NOTE: Use the slower speeds until you are familiar
with the operation of the snow thrower.
With the engine running near top speed, move 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 traction control against the right
handle and the snow thrower will move. Release it
and the drive motion will stop.
IMPORTANT:
NEVER move shift lever without first
releasing the traction control. Doing so will cause
premature wear to drive system’s friction wheel rubber.
To Engage Augers
To engage the augers and start the snow throwing
action, squeeze the auger control against the left
handle.
To disengage power to the augers, release both the
auger control and the traction control, if engaged,
Auger Control Test
IMPORTANT:
Perform the following test before
operating the snow thrower for the first time and at the
start of each winter season.
Check the adjustment of the auger control as follows:
When the auger control is released and in the
disengaged “up” position, the cable should have
very little slack, but should NOT be tight.
WARNING: Do not over-tighten the cable.
Over-tightening may prevent the auger from
disengaging and compromise the safety of the
snow thrower.
