A. Electric Starter
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.
Cold Start
1. Determine whether your house wiring is a three- wire grounded system. Ask a licensed electrician if you are not certain.
_ ARNING: The electric starter must beproperly grounded at all times to avoid the
possibility of electric shock to the operator. If your house wiring system is not a three-wire
grounded system, do not use this electric starter under any conditions.
2. 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.
NOTE: When connecting the power cord, always connect cord to starter on engine first, then plug the
other end into a three-hole grounded 120 Volt receptacle. When disconnecting the power cord,
always unplug the end from the three-hole, grounded receptacle first.
3. Attach spark plug wire to spark plug.
4. Make sure that the auger control bail and the drive control bail are disengaged.
5. Remove the keys from the plastic bag. Push key
into the ignition slot. Do not turn the key. Keep second key in a safe place.
6. Move the choke knob to FULL choke position.
7. Move throttle control to the FAST position.
8. Connect power cord to the switch box on engine.
NOTE: When engaging the electric starter, a slight hesitation of a few seconds may occur before the engine starts to turn. This is normal.
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 fora few minutes because the engine will not develop full power until
it reaches operating temperature. Operate at FULL throttle when throwing snow.
Warm Start If restarting a warm engine, rotate choke to OFF
instead of FULL and press the starter button. Do not push the primer button.
B. Recoil Starter
Make sure that the auger control bail and the drive control bail are released.
Cold Start
1. Move throttle control to FAST position.
2. 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.
3. Rotate choke control to FULL choke position.
4. Push primer button while covering the vent hole. Remove your finger from the primer between primes.
Do not prime if temperature is above 50° F. Prime two times when temperature is between Vent Hole
50°F and 15°F and four times below 15°F.
5. 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.
6. 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.

throwing snow.
NOTE: If the starter motor runs but the engine does not
turn over, the starter gear may have frozen. Place the
snow thrower in a warmer part of the garage till the gear is free of accumulated ice.
Frozen Recoil Starter If the starter is frozen and will not turn the engine,
proceed as follows:
1. Pull as much rope out of the starter as possible.
2. Release the starter handle and let it snap back
against the starter.
3. If the engine still fails to start, repeat the first two steps. Ifcontinued attempts do not free starter,
follow the electric starter procedures to start.
Avoid freezing of the recoil starter by referring to instructions in the next column.
Warm Start If restarting an engine after a temporary shut- down,
rotate choke to OFF instead of FULL and do not prime. Pull the starter handle as instructed before.
Before Stopping
1. Run engine for a few minutes to help dry off any moisture on engine.
2. To avoid possible freeze-up of the starter, follow
these steps:
Recoil Starter

Checking Oil Level
Refer to the accompanying engine manual for details on engine maintenance. A few essential
points for good performance by the snow thrower
are listed here.
Before operating snow thrower, check the oil level by following steps below.
NOTE: Although multi-viscosity oils (5W30, 10W30
etc.) improve starting in cold weather, these multi-
viscosity oils also result in higher oil consumption when
used above 32°F. Check your snow thrower's engine oil level more frequently to avoid possible engine damage from running low on oil.
1. With engine on level ground, oil must be to FULL
mark on dipstick. See Figure 13.
2. Stop engine and wait several minutes before
checking oil level. Remove oil fill cap and dipstick.
3. Wipe dipstick clean, insert itinto oil fill hole and
tighten securely.
Remove dipstick and check. If oil is not up to the FULL mark on dipstick, add oil.
