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 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 ON position.
Push primer button three times,
making sure to cover vent hole
when pushing.
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. Always cover
vent hole in primer button when pushing. At
temperatures below 15°F, additional priming may
be necessary .
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 prevent possible freeze-up of starter:
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 recepta-
cle 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. Disconnect
the spark plug wire from the spark plug to prevent
accidental starting while equipment is unattended.
NOTE: Keep key 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 Wheel 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 traction control against the right handle to
move the snow thrower; release it to stop.
IMPORTANT:
NEVER move the shift lever without first
releasing the traction 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 traction control, if engaged.
Operating Tips
NOTE: Allow the engine to warm up for a few minutes.
The engine will not develop full power until it reaches
operating temperature.
If possible, remove snow immediately after it falls.
Discharge snow downwind whenever possible.
Slightly overlap each previous path.
Set the skid shoes 1/4" below the shave plate for
normal usage. Adjust it upward for hard-packed
snow and downward when using on gravel or
crushed rock.
