How To Adjust The Height Of The Skids (Figure 2)

CAUTION: Any greasing or oiling of the above components can cause contamina- tion of the friction wheel (3). If the disc drive plate (1) or the friction wheel (3) be- come contaminated with grease or oil, damage to the friction wheel will result.

3.The auger gear case is lubricated at the fac- tory and does not require additional lubrica- tion. If for some reason the lubricant leaks out, have the auger gear case checked by a factory authorized service center.

How To Adjust The Height Of The Skids (Figure 2)

This snow thrower is equipped with two height adjustable skids (7). These skids elevate the front of the snow thrower. For normal hard sur- faces, such as a paved driveway or walk, adjust the skids as follows.

1.Put the snow thrower on a level surface.

2.Make sure both tires are equally inflated. The correct air pressure is 14 PSI (1 BAR) to 17 PSI (1.25 BAR). Do not exceed the maxi- mum amount of air pressure shown on the side of the tire.

3.Put the extra shear bolts (found in the parts bag) under each end of the scraper bar (15) next to the adjustable skids (7).

4.Loosen the mounting nuts (16) that hold the adjustable skids (7). To bring the front of the snow thrower down, raise each adjustable skids (7) . Tighten the mounting nuts (16).

NOTE: For rocky or uneven surfaces, raise the front of the snow thrower by moving the adjustable skids (7) down.

WARNING: Be certain to maintain proper ground clearance for the area to be cleared. Objects such

as gravel, rocks or other debris, if struck by the impeller, can be thrown with suffi- cient force to cause personal injury, prop- erty damage or damage to the snow throw- er.

How To Adjust

The Scraper Bar (Figure 2)

After considerable use, the scraper bar (15) will become worn. The scraper bar (15), in con- junction with the skids, must be adjusted to allow 1/8 inch clearance between the scraper bar

(15)and the sidewalk or area to be cleared.

1.Put the snow thrower on a level surface.

2.Make sure both tires are equally inflated. The correct air pressure is 14 PSI (1 BAR) to 17 PSI (1.25 BAR). Do not exceed the maxi- mum amount of air pressure shown on the side of the tire.

3.Loosen the carriage bolts and nuts that hold the scraper bar (15) to the auger housing

(4).

4.Adjust the scraper bar (15) to allow 1/8 inch clearance between the scraper bar (15) and the sidewalk or area to be cleared.

5.Tighten the carriage bolts and nuts. Make sure that the scraper bar (15) is parallel with the sidewalk or area to be cleared.

6.To extended the life of the scraper bar (15), remove and reverse the mounting of the scraper bar (15).

How To Check And Adjust The Cables

The traction drive cable and the auger drive cable are adjusted at the factory. During normal use, a cable can become stretched and must be checked and adjusted as follows.

How To Check The Cables (Figure 11)

1.To check for correct adjustment, disconnect the “Z” fitting (1) from the drive lever (2).

2.Move the drive lever (2) forward until the drive lever (2) is contacting the plastic bumper (3).

3.The control cable is correctly adjusted if the center of the “Z” fitting (1) is aligned (4) with the hole in the drive lever (2) and there in no droop in the cable.

How To Adjust The Auger Drive Cable

1.Remove the gas from the gas tank. Stand the snow thrower up on the front end of the auger housing.

WARNING: Drain the gasoline out- doors, away from fire or flame.

2.(Figure 11) Disconnect the “Z” fitting (1) from the drive lever (2).

3.(Figure 12) Pull the spring cover up to ex- pose the spring (5). Push the cable (6) through the spring (5) to expose the square end (7) on the cable (6).

4.Hold the square end (7) with pliers and ad- just the locknut (8) in or out until the excess slack is removed.

5.Pull the cable (6) back through the spring

(5).

6.(Figure 11) Connect the “Z” fitting (1) to the drive lever (2).

NOTE: When the auger drive belt is adjusted or replaced, check and adjust the cable.

How To Adjust The Traction Drive Cable

1.Remove the gas from the gas tank. Stand the snow thrower up on the front end of the auger housing.

WARNING: Drain the gasoline out- doors, away from fire or flame.

2.(Figure 16) Loosen the bolts (3) on each side of the bottom panel (2).

3.Remove the bottom panel (2).

4.(Figure 11) Disconnect the “Z” fitting (1) from the traction drive lever (2).

5.(Figure 22) Slide the cable boot (3) off the cable adjustment bracket (4).

6.Push the bottom of the traction control cable (5) through the cable adjustment bracket (4) until the “Z” hook (6) can be re- moved.

7.Remove the “Z” hook (6) from the cable adjustment bracket (4). Move the “Z” hook

(6) down to the next adjustment hole.

8.Pull the traction control cable (5) up through the cable adjustment bracket (4).

9.Put the cable boot (3) over the cable ad- justment bracket (4).

10.(Figure 11) Install the “Z” fitting (1) to the traction drive lever (2).

11.(Figure 10) To check the adjustment, de- press the drive lever and check the length “A” of the drive spring (7). In correct adjust- ment, the length “A” of the drive spring (7) is as follows:

minimum 3 inches (76 mm.) maximum 3-3/8 inches (85 mm.).

12.(Figure 16) Install the bottom panel (2).

13.Tighten the bolts (3) on each side of the bot- tom panel (2).

How To Adjust The Belts

The belts will stretch during normal use. If you need to adjust the belts due to wear or stretch, proceed as follows.

How To Adjust The Auger Drive Belt

If the snow thrower will not discharge snow, check the adjustment of the auger drive cable. See “How To Check And Adjust The Cables” in the Maintenance section. If the adjustment is correct, then check the condition of the auger drive belt. If the auger drive belt is damaged, replace the auger drive belt. See “How To Re- place The Belts” in the Maintenance section. If the auger drive belt is loose, adjust as follows.

1.Disconnect the spark plug wire.

2.(Figure 13) Remove screw (2) from belt cover (1). Remove the belt cover (1).

3.(Figure 14) Loosen the nut (2) on the idler pulley (3) Move the idler pulley (3) 1/8 inch toward the auger drive belt (4).

4.Tighten the nut (2).

5.(Figure 15) Depress the auger drive lever. Check the tension on the auger drive belt

(4). In correct adjustment, the auger drive belt (4) will deflect 1/2 inch (5) with moder- ate pressure. If the adjustment is not correct, repeat the adjustment.

6.(Figure 13) Install the belt cover (1). Tighten screw (2).

7.Check the adjustment of the auger drive cable. See “How To Check And Adjust The Cables” in the Maintenance section.

8.Attach the spark plug wire.

Traction Drive Belt

The traction drive belt has constant spring pres- sure and does not require an adjustment. If the traction drive belt is slipping, replace the belt.

See “How To Replace The Belts” in the Mainte- nance section.

How To Replace The Belts

The drive belts are of special construction and must be replaced with original factory replace- ment belts available from your nearest autho- rized service center.

Some steps require the assistance of a second person.

How To Remove the Auger Drive Belt

If the auger drive belt is damaged, the snow thrower will not discharge snow. Replace the damaged belt as follows.

1.Disconnect the spark plug wire.

2.(Figure 16) Loosen the bolts (3) on each side of the bottom panel (2).

3.Remove the bottom panel (2).

4.(Figure 13) Remove screw (2) from belt cover (1). Remove the belt cover (1).
