Read and follow the assembly and adjustment
instructions for your snow thrower. All fasteners
are in the parts bag. Do not discard any parts or
material until the unit is assembled.

WARNING: Before doing any
assembly or maintenance to the
snow thrower, remove the wire

from the spark plug.

NOTE: In this instruction book, left and right
describe the location of a part from the
operator’s position behind the unit.
NOTE: Torque is measured in foot pounds
(metric N.m). This measurement describes
how tight a nut or bolt must be. The torque is
measured with a torque wrench.
NOTE: Fasteners and loose parts are shown

at full size in Figure 2 on page 15.
NOTE: Illustrations are located on page 2

and on pages 16 through 20.

How To Remove The Snow Thrower

From The Carton

1.

(Figure 3) 

The snow thrower is shown in the

shipping position.

2. Remove packing material from wheels,

handle, and auger housing.

3. Locate and remove the parts bag (some

models do not have a parts bag).

4. Cut open the end of the carton next to the

handle.

5. To roll the snowthrower off of the carton, pull

on the handle.

CAUTION: DO NOT back over cables.

6. Remove any packing material that remains

from handle and auger housing.

7.  Cut black plastic shipping ties that may 
 

HANDLE.

8. If the control cables have become

disconnected from the control levers, then
attach the cable to the levers (see Owner’s
Manual for illustration of cable and lever).

How To Assemble The Handle

1.

(Figure 4) 

Loosen, but do not remove, the

fasteners (1)

 in the upper holes of the lower

handle.

2. Raise the 

upper handle (2)

 to the operating 

position.

NOTE: Make sure the cables are not
caught between the upper and lower
handle.

3.  Tighten all handle fasteners.

Check The Cables

1.

(Figure 8) 

Check the 

traction drive cable

(1)

 and the 

auger drive cable (2)

. If the

bottom of the cables have become
disconnected, reinstall the cables.

2.

(Figure 10) 

If the top of the 

cables (5)

 have

become disconnected from the 

drive

levers (6)

, attach the 

cables (5)

 to the 

“Z”

fitting (7)

.

How To Set The Skid Height 

(Figure 1)

The snow thrower is equipped with 

height

adjustable skids (7)

 mounted on the outside of

the

auger housing (4)

. To adjust the height of

the skids, see “How To Adjust The Height Of
The Skids” in the Maintenance section.

How To Set The Length Of The Cables

The cables were adjusted at the factory and no
adjustments should be necessary. However,
after the handles are put in the operating
position, the cables can be too tight or too loose.
If an adjustment is necessary, see “How To
Check And Adjust The Cables” in the Service
And Adjustment section.

How To Assemble The Drift Cutter
(if equipped)

Drift cutters are used to cut a path through snow
deeper than the auger housing.
1.

(Figure 11) 

Loosen the 

fasteners (2)

 that

secure the 

drift cutters (1)

 to the auger

housing.

2. Raise the 

drift cutters (1) 

to the desired

height.

3. Tighten the 

fasteners (2).

How To Prepare The Engine

NOTE: The engine was shipped from the

factory filled with oil. Check the level of the

oil. Add oil as needed.

WARNING: Follow the engine
manufacturer’s instructions for the
type of fuel and oil to use. Always

use a safety fuel container. Do not smoke
when adding gasoline to the engine. When
inside an enclosure, do not fill with
gasoline. Before you add fuel, stop the
engine. Let the engine cool for several
minutes.

Check the oil. See the engine manufacturer’s
instructions for the type of fuel and oil to use.
Before you use the unit, read the information on
safety, operation, maintenance, and storage.

Important! Before You Start Operating

Check the fasteners. Make sure all
fasteners are tight.

NOTE: Illustrations are located on page 2

and on pages 16 through 20.
CAUTION: Use only attachments and
accessories approved by the manufacturer
of the snow thrower (such as tire chains,
electric start kits, etc.).

Know Your Snow Thrower 

(Figure 1)

Read this Instruction Book and safety rules
before operation the snow thrower. Compare the
illustration with your snow thrower to familiarize
yourself with the location of various controls and
adjustments.

How To Control The Discharge Of 

The Snow

WARNING: Never direct the
discharge of snow toward
bystanders.

WARNING: Always stop the engine
before unclogging the discharge
chute or the auger housing and

before leaving the snow thrower.

1.

(Figure 1) 

Turn the 

crank assembly (2)

 to

change the discharge direction of the snow.

2. Turn the 

upper chut assembly(21)

the distance.

Move the

chute deflector (2)

 UP for more distance, DOWN for less distance. 

How To Assemble The Chute Deflector

1. Turn

 crank assembly (18, Figure 5)

 until 

the arrow on 

outer ring (2, Figure 7) 

of 

chute ring assembly points forward. 

NOTE: The chute ring assembly (1) comes 
installed on the unit from the factory (see
Figure 7).

2. Place 

chute ring (3)

 onto

 outer ring (2)

 

so the slot in the chute ring aligns with 
the arrow on the outer ring.

3. Install 

chute deflector (4)

 using three 

screws 

(5) 

and 

nuts (6)

 in holes as shown. The chute   

deflector must point forward for proper 
installation.

4. Tighten screws snugly but be careful not to 

over-tighten. 

secure the control cables to the LOWER

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, pull out 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 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          Wet, Heavy
Speed 2          Light
Speed 3          Very Light
