OPERATION

TO START ENGINE 

•  Be sure fuel shut-off valve is in the “OPEN” position.
Your snow thrower engine is equipped with a recoil starter.  
COLD START
1.  Insert safety ignition key (packed separately in parts 

bag) into ignition slot until it clicks.  DO NOT turn the key.  

Keep the extra safety ignition key in a safe place.

2.  Place throttle control in “FAST” position.
3.  Rotate choke control to “FULL” position.
4.  Push the primer four (4) times if the temperature is 

below 15°F, or two (2) times if temperature is between 

15° and 50°F.  If temperature is above 50°F, priming is 

not nec es sary.

NOTE

:  Over priming may cause flooding, preventing the 

engine from starting. If you do flood the engine, wait a few 

minutes be fore at tempt ing to start and DO NOT push the 

primer. 
5.  Pull recoil starter handle quickly. Do not allow starter 

rope to snap back.

6.  When the engine starts, release the recoil starter han dle 

and slowly move the choke control to the “OFF” posi-

tion.

Allow the engine to warm up for a few minutes.  Engine will 

not develop full power until it has reached normal operat-

ing temperature.
WARM START
Follow the steps above, keeping the choke in the “OFF” 

position.  DO NOT push the primer.

BEFORE STOPPING

Run the engine for a few minutes to help dry off any mois-

ture on the engine.

IF RECOIL STARTER HAS FROZEN

If the recoil starter has frozen and will not turn the engine, 

proceed as follows:
1.  Grasp the recoil starter handle and slowly pull as much 

rope out of the starter as possible.

2.  Release the recoil starter handle and let it snap back 

against the starter.

If the engine still fails to start, repeat the above steps.

SNOW THROWING TIPS

•  Always operate the snow thrower with the engine at 

full throttle. Full throttle offers the best performance.

•  Go slower in deep, freezing or heavy wet snow. Use 

the drive speed control, NOT the throttle, to adjust 

speed.

•  It is easier and more efficient to remove snow im me -

di ate ly after it falls.

• 

The best time to remove snow is the early morning. At 

this time the snow is usually dry and has not been ex-

posed to the direct sun and warming tem per a tures.

•  Slightly overlap each successive path to ensure all 

snow will be removed.

•  Throw snow downwind whenever possible.
• Ad 

just the skid plates to proper height for current snow 

con di tions.  See “TO ADJUST SKID PLATES” in this 

section of this manual.

•  For extremely heavy snow, re duce the width of snow 

removal by over lap ping previous path and moving 

slowly.

• 

Keep engine clean and clear of snow during use. This 

will help air flow and extend engine life. 

• 

After snow-throwing is completed, allow engine to run for 

a few minutes to melt snow and ice off the engine.

•  Clean the entire snow thrower thoroughly after each 

use and wipe dry so it is ready for next use.

WARNING:  Do not operate snow 

thrower if weather conditions im pair vis-

ibility.  Throwing snow dur ing a heavy, 

windy snowstorm can blind you and be 

hazardous to the safe operation of the 

snow thrower.
