Cold Start
NOTE: If the unit shows any sign of motion (drive or
augers) with the clutch grips disengaged, shut the
engine off immediately. Readjust as instructed in the
“Final Adjustments” section on page 11.
WARNING: The electric starter must be properly
grounded at all times to avoid possibility of electric
shock which may injure the operator.
•
Determine whether your house wiring is a three-
wire grounded system. Ask a licensed
electrician if you are not certain.
WARNING: If your house wiring system is
not a three-wire grounded system, do not use
this electric starter under any conditions.
• If your house wiring system is grounded and a
three-hole receptacle is not available at the point
the snow thrower 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 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.
• Attach spark plug wire to spark plug.
• Make sure that the auger drive and the traction
drive levers are in the disengaged RELEASED
position.
• Move throttle control lever to FAST position.
• Remove the keys from the plastic bag. Push key
into the ignition slot. Make sure it snaps into
place. Do not turn key. Save the second key.
• Rotate the choke knob to FULL choke position.
• Connect power cord to switch box on engine.
• Plug the other end of the power cord into a
three-hole, grounded 120 volt A.C. receptacle.
WARNING: Do not use primer while
starting the engine with an electric starter.
• Push down on the starter button until the engine
starts. Do not crank for more than 10 seconds at
a time. This electric starter is thermally
protected. If overheated, it will stop
automatically and can be restarted only when it
has cooled to a safe temperature (a wait of
about 5 to 10 minutes is required).
• When the engine starts, release the starter
button and slowly rotate the choke to OFF
position. If the engine falters, rotate the choke to
FULL and then gradually to OFF.
• Disconnect the power cord from the receptacle
first and then from the switch box on the engine.
• Allow the engine to warm up for a few minutes
because the engine will not develop full power
until it reaches operating temperature.
• Operate the engine at full throttle (FAST) when
throwing snow.
Warm Start
• If restarting a warm engine after a shut down,
rotate choke to OFF instead of FULL and press
the starter button.
B. Recoil Starter
Make sure that the engine has sufficient oil and the
auger drive and the traction drive levers are released.
•
Move throttle control to FAST position.
• Push key into the ignition slot so that it snaps
into place. Do not turn key. Remove plastic bag
and keep the second key in a safe place.
• Rotate choke control to FULL choke position.
• Push the primer button while covering the vent
hole. Remove your finger from the primer between
primes. Do not prime if temperature is above
50
o F; prime two times between 50 o F and 15 o F;
and prime four times below 15 o F.
• Pull the starter handle rapidly. Do not allow the
handle to snap back, but allow it to rewind slowly
while keeping a firm hold on the starter handle.
• As the engine warms up and begins to operate
evenly, rotate the choke knob slowly to OFF
position. If the engine falters, return to FULL
choke, then slowly move to OFF choke position.
• Allow the engine to warm up for a few minutes
because the engine will not develop full power
until it reaches operating temperature.
• Operate the engine at full throttle (FAST) when
throwing snow.
Warm Start
• If restarting a warm engine after a temporary
shut down, rotate choke to OFF instead of FULL
and do not prime. Press the starter button.
Frozen Recoil Starter
If the starter is frozen and will not turn the engine,
proceed as follows:
•
Pull as much rope out of the starter as possible.
• Release the starter handle and let it snap back
against the starter.
• If the engine still fails to start, repeat the first two
steps. If continued attempts do not free starter,
follow the electric starter procedures to start.
• Avoid possible freezing of recoil starter and the
engine controls.
Operating Snow Thrower
To Engage Drive
• With the engine running near top speed, move
shift lever to one of six FORWARD positions or
two REVERSE positions. Select a speed
appropriate for the snow conditions that exist.
