To Start Engine

WARNING:
Be sure no one other than the
operator is standing near the snow thrower
while starting or operating. Do not operate this
snow thrower unless the chute assembly has
been properly installed and is secured.

Electric Starter

For location of all the engine controls referred to in this
section, see Figure 7 inset.
Before starting, make sure that the engine has suffi-
cient oil. The snow thrower engine is equipped with a
120 volt A.C. electric starter and recoil starter. The
electric starter is equipped with a three-wire power
cord and plug and is designed to operate on 120 volt
AC household current. Follow all instructions carefully.
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 of the Assembly
Instructions.
WARNING:
The electric starter must be
properly grounded at all times to avoid the
possibility of electric shock which may be
injurious to the operator.
1. 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 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.
2. Attach spark plug wire to spark plug.
3. Turn fuel valve on, if so equipped.
4. Make sure that the auger and drive controls are in
the disengaged (up) position.
5. Move throttle control lever to FAST position.
6. Push key into the ignition slot and snap in place. Do
not turn key.
7. Connect power cord to switch box on the engine.
8. Plug the other end of the power cord into a three-
hole, grounded 120 volt A.C. receptacle.
9. Rotate choke knob to FULL choke position (cold
engine start). If engine is warm, place choke in OFF
position instead of FULL.
10. Push the primer three times.
11. 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 5 -10 minutes is required).
12. 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.
13. Disconnect the power cord from the receptacle first
and then from the switch box on the engine.
14. 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.

Recoil Starter

Make sure that the engine has sufficient oil and the
auger drive and the drive control levers are released.
Cold Start
1. Move throttle control to FAST position.
2. Turn fuel valve on, if so equipped.
3. Push key into the ignition slot and snap in place. Do
not turn key.
4. Rotate choke control to FULL choke position.
5. 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
two times between 50
o
times below 15 F.
6. 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.
7. As the engine warms up, rotate the choke knob
slowly to OFF position. If the engine falters, return
to FULL choke, then slowly move to OFF choke
position.
8. Allow the engine to warm up for a few minutes
because the engine will not develop full power until
it reaches operating temperature.
9. Operate the engine at full throttle (FAST) when
throwing snow.
Warm Start
1. If restarting a warm engine after a temporary shut
down, rotate choke to OFF instead of FULL and do
not prime. Pull starter handle as instructed earlier.
