WARNING

Electric Starter

(if equipped)

Some models of the snow thrower may be equipped 
with an optional 120 volt A.C. electric starter. This 
electric starter, with a three-wire power cord and plug, is 
designed to operate on 120 volt AC household current. 
Follow the steps below to use the electric starter.

Cold Start:

1.  Determine whether your house wiring is a three-wire 

grounded system. Ask a licensed electrician if you 
are not certain.

WARNING: The electric starter must 
be properly 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 and the drive 

control 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.  Turn fuel valve on, if so equipped.
9.  Connect power cord to the switch box on engine. 
10. Plug the other end of the power cord into a three-

hole, grounded 120 volt AC receptacle.

11. Push primer button three times.
12. Push down on the starter button until the engine 

starts. Do not crank for more than 5 seconds at a time.

WARNING: Severe damage to electric 
starter is possible if you continue to 
crank for more than 5 seconds without 
a cool-down.

13. 

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. 

NOTE: When engaging the electric starter, a slight 
hesitation of a few seconds may occur before the 
engine starts to turn. This is normal and is not harmful 
to the engine.

14. Disconnect the power cord from the receptacle first 

and then from the switch box on the engine.

15. Allow the engine to warm up for a few minutes 

because the engine will not develop full power until it 
reaches operating temperature.

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 or storage 
shed till the gear is free of the accumulated ice.

Warm Start:

1.  If restarting a warm engine, rotate choke to OFF 

instead of FULL and press the starter button. Do not 
push the primer button.

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 

  a.  With the engine running, pull the starter rope with 

a rapid, continuous full arm stroke three or four times.

Electric Starter (if equipped)

  a.  Connect power cord to switch box, then to 120  

  Volt AC receptacle.

  b.  While the engine is running, push the starter  

  button and spin the starter for several seconds.

  c.  Disconnect power cord from the receptacle first,  

  then from the snow thrower.

NOTE: The unusual sound from pulling the starter rope or 
from spinning the starter will not harm the engine.
3.  While standing in the operator’s position (behind the snow 

thrower), engage the auger control for a few seconds to 
clear any remaining snow and ice from the chute assembly.

To Stop The Snow Thrower

1.  To stop the wheels, release the drive control.
2.  To stop throwing snow, release the auger control.
3.  To stop engine, push throttle control lever to OFF or 

pull out the key(either method works). Do not turn key.

WARNING: The temperature of muffler 

and the surrounding areas may exceed 
150º F. Avoid these areas

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:
1.  When the auger control is released and in the 

disengaged “up” position, the cable should have very 
little slack, but should NOT be tight.
