SECTION 4:  OPERATING YOUR SNOW THROWER

Before Starting

WARNING: 

Read, understand, and follow

all instructions and warnings on the machine
and in this manual before operating. 

Gas & Oil Fill-Up 

Service the engine with gasoline and oil as instructed in 
the 

Tecumseh Engines 

manual packed separately with 

your snow thrower. 

Read instructions carefully.

WARNING: 

Use extreme care when 

handling gasoline. Gasoline is extremely 
flammable and the vapors are explosive. 
Never fuel the machine indoors or while the 
engine is hot or running. Extinguish cigarettes, 
cigars, pipes and other sources of ignition.

•

A small plastic cup may be located inside the fuel fill 
opening beneath the gas cap. Remove and discard 
this cup before filling up the tank.

Starting The Engine

•

Attach spark plug wire to spark plug. Make certain 
the metal loop on the end of the spark plug wire 
(inside the boot) is fastened securely over the metal 
tip on the spark plug. 

•

Make certain both the auger control and drive 
control are in the disengaged (released) position.

•

Move throttle control up to FAST position. Insert 
ignition key into slot. Make sure it snaps into place. 

Do not attempt to turn the key

.

NOTE: 

The engine cannot start unless the key is

inserted into ignition switch. 

Electric Starter 

(on models so quipped)

 

•

Determine that your home’s wiring is a three-wire 
grounded system. Ask a licensed electrician if you 
are not certain. 

CAUTION: 

If your home’s wiring system 

is not a three-wire grounded system

, do 

not use this electric starter under any 
conditions.

WARNING: 

The optional electric starter is 

equipped with a grounded three-wire power 
cord and plug, and is designed to operate on 
120 volt AC household current. It must be 
used with a properly grounded three-prong 
receptacle at all times to avoid the possibility 
of electric shock. Follow all instructions 
carefully prior to operating the electric starter. 

WARNING: 

If your home electrical 

system is grounded

, but a three-hole 

receptacle is not available, do not use your 
snow thrower’s electric starter.

If you have a grounded three-prong receptacle

, 

proceed as follows:

•

Plug the extension cord into the outlet located on 
the engine’s surface. Plug the other end of 
extension cord into a three-prong 120-volt, 
grounded, AC outlet in a well-ventilated area. 

•

Rotate choke control to FULL choke position (cold 
engine start). 

NOTE: 

If the engine is already warm, place choke

control in the OFF position instead of FULL.

•

Push the primer two or three times for cold engine 
start, making sure to cover vent hole in the center of 
the primer when pushing. 

NOTE: 

DO NOT use primer to restart a warm engine

after a short shutdown.

•

Push starter button to start engine.

•

Once the engine starts, immediately release starter 
button.

•

As the engine warms, slowly rotate the choke 
control to the OFF position. If the engine falters, 
quickly rotate the choke control back to FULL and 
then slowly into the OFF position again.

•

When disconnecting the extension cord, always 
unplug the end at the three-prong wall outlet before 
unplugging the opposite end from the snow 
thrower.

Recoil Starter

•

Rotate choke control to FULL choke position (cold 
engine start). 

NOTE: 

If the engine is already warm, place choke

control in the OFF position instead of FULL.

•

Push the primer two or three times for cold engine 
start, making sure to cover vent hole in the center of 
the primer when pushing. 

NOTE: 

DO NOT use primer to restart a warm engine

after a short shutdown.

NOTE: 

Additional priming may be necessary if the

temperature is below 15° Fahrenheit.

•

Grasp the recoil starter handle and slowly pull the 
rope out. At the point where it becomes slightly 
harder to pull the rope, slowly allow the rope to 
recoil.

•

Pull the starter handle with a firm, rapid stroke.
