How To Throw Snow 

(Figure 1)

1. Engage the 

auger drive lever (5)

.

2. To stop throwing snow, release the 

auger

drive lever (5)

.

WARNING: The operation of any
snow thrower can result in foreign
objects being thrown into the eyes,

which can result in severe eye damage.
Always wear safety glasses or eye shields
while operating the snow thrower. We
recommend standard safety glasses or use
a wide vision safety mask over your
glasses.

Before Starting The Engine

1. Before you service or start the engine,

familiarize yourself with the snow thrower. Be
sure you understand the function and
location of all controls.

2. Check the tension of the clutch cable before

starting the engine. See “How To Adjust The
Clutch Cable” in the Maintenance section of
this manual.

3. Make sure that all fasteners are tight.

4. Make sure the height adjust skids are

properly adjusted. See “How To Adjust The
Height Of The Skids” in the Maintenance
section of this manual.

5. Check the air pressure in the tires. The

correct air pressure is 14 PSI (1 BAR) to 17
PSI (1.25 BAR). Do not exceed the
maximum amount of air pressure shown on
the side of the tire.

How To Stop The Engine 

(Figure 1)

1. Pull out the 

fuel valve lever (15) 

to the OFF

position. (If with it)

2. Turn the 

safety key (8).

CAUTION: To stop the engine, do not move
the choke control to CHOKE position.
Backfire or engine damage can occur.

How To Start The Engine 

(Figure 1)

Models equipped with an Electric Starter

NOTE: An electric starter kit can be added to
recoil start engines. Electric starter kits are
available from your nearest authorized
service center.

WARNING: The starter is equipped
with a three-wire power cord and
plug and is designed to operate on

A.C. household current. The power cord
must be properly grounded at all times to
avoid the possibility of electrical shock
which can injure the operator. Carefully
follow all instructions in the “How To Start
The Engine” section. Make sure that your
house wiring is a three-wire grounded
system. If you are not sure, ask a licensed
electrician. If your house wire system is not
a three-wire grounded system, do not use
this electric starter under any conditions. If
your system is grounded but a three-hole
grounded receptacle is not available to start
the engine, have a three-hole grounded
receptacle installed by a licensed
electrician. To connect an A.C. power cord,
always connect the power cord to the
switch box (11) on the engine first. Then,
plug the other end into the three-hole
grounded receptacle. When disconnecting
the power cord, always unplug the end from
the three-hole grounded receptacle first.

How To Start A Cold Engine 

(Figure 1)

1. Check the engine oil.
2. Fill the fuel tank with regular unleaded petrol.

See “How To Prepare The Engine”.

3. Make sure the 

traction drive lever (1)

 and

the

auger drive lever (5)

 are in the

disengaged (released) position.

8.

(Electric Start) 

Connect the power cord to

the starter motor located on the engine.

9.

(Electric Start) 

Plug the other end of the

power cord into a three-hole, grounded 
A.C. receptacle. (See the WARNING in
this section).

10.Push the 

primer button (9).

 Every time you

push the 

primer button (9)

, wait two

seconds. For the number of times required to
push the 

primer button (9),

 see the engine

manufacturer’s instructions.

11.

(Electric Start) 

Push on the 

electric start

button (10) 

until the engine starts. Do not

crank for more than 5 seconds at a time.
Wait one minute between starts to allow the
starter to cool.

12.

(Recoil Start) 

Slowly pull the 

recoil starter

handle (12)

 until resistance is felt and then

pull rapidly to start the engine. Do not allow
the

recoil starter handle (12)

 to snap back.

Slowly return the 

recoil starter handle (12).

13.If the engine does not start in 5 or 6 tries,

See the “Trouble Shooting Chart”
Instructions.

14.Allow the engine to warm up for several

minutes. As the engine warms up, adjust the

choke knob (14) 

toward the RUN position.

Wait until the engine runs smoothly before
each choke adjustment.

15.

(Electric Start) 

First disconnect the power

cord from the three-hole receptacle. Then,
disconnect the power cord from the starter
motor.

NOTE: In temperatures below 0 F (-18 C),
allow the engine to warm up for several
minutes before blowing snow.

WARNING: Never run the engine
indoors or in enclosed, poorly
ventilated areas. Engine exhaust

contains carbon monoxide, an odorless
and deadly gas. Keep hands, feet, hair and
loose clothing away from any moving parts
located on the engine or the snow thrower.
The temperature of muffler and nearby
areas may exceed 150

°

F (66

°

C). Avoid

these areas.

How To Start A Warm Engine 

(Figure 1)

If an engine has been running and is still warm,
