How To Stop The Snow Thrower
(Figure 1)
1. To stop discharging snow, release the auger
drive lever (5).
2. To stop the wheels, release the traction
drive lever (1).
3. To stop the engine, move the stop switch
(13) to the OFF position.
CAUTION: To stop the engine, do not move
the choke control to CHOKE position.
Backfire or engine damage can occur.
How To Go Forward or Backward
(Figure 1)
1. To change the ground speed, first release the
traction drive lever (1) and then move the
speed shift lever (6) to the desired speed.
2. Ground speed is determined by snow
conditions. Select the speed by moving the
speed shift lever (6) into the appropriate
notch on the shift lever plate.
Speed 1, 2 Wet, Heavy
Speed 3 Light
Speed 4 Very Light
Speed 5, 6 Transport only
3. To go forward, engage the traction drive
lever (1). Maintain a firm hold on the handle
as the snow thrower starts to move forward.
Guide the snow thrower by moving the
handle either left or right. Do not attempt to
push the snow thrower.
4. To go backward, release the tractor drive
lever (1).
5. Move the speed shift lever (6) into either
first or second reverse.
6. Engage the traction drive lever (1).
IMPORTANT: Do not move the speed shift
lever (6) while the traction drive lever (1) is
engaged.
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.
How To Use The Wheel Lockout Pin
(Figure 13)
1. The right hand wheel is secured to the axle
with a klick pin (1). This unit was shipped
with this klick pin (1) through the wheel hole
in the locked position (2).
2. For ease of maneuverability in light snow
conditions, change the klick pin (1) to an
unlocked position (3).
3. Disconnect the klick pin (1) from the wheel
locked position (2). Push the klick pin (1)
through the unlocked axle hole only. The unit
is now in the single wheel drive unlocked
position (3).
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. Push the stop switch (13) to the OFF

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.
4. Push the stop switch (13) to the ON
position.
5. Push in the safety key (8).
6. Rotate the choke knob (14) to the CHOKE
position.
7. (Electric Start) Connect the power cord to
the starter motor located on the engine.
8. (Electric Start) Plug the other end of the
power cord into a three−hole, grounded
A.C. receptacle. (See the WARNING in
this section).
9. 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.
10. (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.
11. (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).
12. If the engine does not start in 5 or 6 tries,
See the “Trouble Shooting Chart”
Instructions.
13. 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.
14. (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,
leave the choke control (14) in the off position
and do not push the primer button (9). If the
engine fails to start, follow the instructions “How
To Start A Cold Engine”.
NOTE: Do not use the primer button (9) to
start a warm engine.
How To Start An Engine With A Frozen Electric
Starter
(Figure 1)
If the electric starter is frozen and will not turn
the engine, follow the instructions below.
1. Pull as much starter rope as possible out of
the starter.
2. Release the starter handle and let it snap
back against the starter. Repeat until the
engine starts.
