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 orange plastic shipping ties that may secure the control cables to the LOWER 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 And Crank Assembly

1.(Figure 4) Loosen, but do not remove, the fasteners (1) in the upper holes of the lower handle.

2.Remove the fasteners and the crank assembly eyebolt (11) from the lower holes of the lower handle.

3.(Figure 1) Put the shift lever (6) into first forward position.

4.(Figure 4) Raise the upper handle (2) to the operating position.

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

5.Install the fasteners and the crank assembly eyebolt (11) that were removed in step 2. DO NOT tighten until all fasteners are in place.

6.(Figure 5) Attach the crank rod (15) to the universal joint assembly (16) with the hair pin (12).

7.(Figure 4) Tighten nut on eye bolt (11). Make sure eye bolt (11) is properly aligned and the crank (18) can freely rotate.

8.Tighten all handle fasteners.

How To Install The Knob(s) (Figure 6)

NOTE: If knob(s) are already installed, go to the next selection.

1.Attach the knob (3) onto the speed shift lever (2). On some models, the knob (3) is attached. To lock in position, tighten the hex jam nut (1) against the bottom of the knob (3).

2.Make sure the speed shift lever (2) functions correctly. Move the speed shift lever (2) through all speeds.

How To Assemble The Chute Deflector

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

1.Turn crank assembly (18, Figure 4) until the arrow on outer ring (2, Figure 7) of chute ring assembly points forward.

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 four 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.

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.

On electric start models, the unit was shipped with the starter cord plugged into the engine. Before operating, unplug the starter cord from the engine.

OPERATION

NOTE: Illustrations are located on page 2 and on pages 33 through 38.

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.(Figure 12) Loosen the wing knob (1) on the chute deflector (2) and move the chute deflector (2) to set the distance. Move the chute deflector (2) UP for more distance, DOWN for less distance. Then tighten the wing knob (1).
