As Required
The following adjustment should be preformed more than once each season.
1.Adjust the auger drive belt after the first 2 to 4 hours, again at mid−season, and twice each season thereafter. See “How To Adjust The Auger Drive Belt” in the Maintenance section.
Lubrication
Every 10 Hours (Figure 14)
1.Lubricate the Zerk fittings (1) every ten hours with a grease gun.
2.Each time a shear bolt is replaced, the auger shaft must also be greased.
3.Lubricate all pivot points.
Every 25 Hours
Chute Rotation Gear
(Figure 5) Lubricate the chute rotation gear (1) with automotive type oil.
Chains
1.(Figure 1) Move the speed shift lever (6) to first gear.
2.Remove the gas from the gas tank. Stand the snow thrower up on the front end of the auger housing (4).
WARNING: Drain the gasoline outdoors, away from fire or flame.
3.(Figure 23) Loosen the bolts (3) on each side of the bottom panel (2).
4.Remove the bottom panel (2).
5.(Figure 15) Lubricate the chains (5) with a chain type lubricant.
6.Wipe the hexshaft and sprockets (6) with 5W30 motor oil.
NOTE: If grease or oil come in contact with the disc drive plate (1) or the friction wheel (3), damage can result. Clean off any oil or grease with a alcohol base solvent.
7.(Figure 23) Install the bottom panel (2).
8.Tighten the bolts (3) on each side of the bottom panel (2).
Items Not To Lubricate (Figure 15)
1.Do not lubricate the hex shaft and sprockets (6). All bearings and bushings are lifetime lubricated. For storage, put a slight amount of 5W−30 motor oil on a cloth and wipe the hex shaft and sprockets (6) to prevent rust.
2.If grease or oil comes in contact with the disc drive plate (1) or the friction wheel
(3), the friction wheel (3) can be damaged. Make sure to thoroughly clean the disc drive plate (1) and the friction wheel (3).
CAUTION: Any greasing or oiling of the above components can cause contamination of the friction wheel (3). If the disc drive plate (1) or the friction wheel (3) become contaminated with grease or oil, damage to the friction wheel will result.

3.The auger gear case is lubricated at the factory and does not require additional lubrication. 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 1)
This snow thrower is equipped with two height adjustable skids (7). These skids elevate the front of the snow thrower. For normal hard surfaces, 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 maximum 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 sufficient force to cause personal injury, property damage or damage to the snow thrower.
How To Adjust The Scraper Bar (Figure 1)
After considerable use, the scraper bar (15) will become worn. The scraper bar (15), in conjunction 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 maximum 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 16)
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 outdoors, away from fire or flame.
2.(Figure 16) Disconnect the “Z” fitting (1) from the drive lever (2).
3.(Figure 17) Pull the spring cover up to expose 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 adjust the locknut (8) in or out until the excess slack is removed.
5.Pull the cable (6) back through the spring
(5).
6.(Figure 16) 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.

5.(Figure 28) 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 removed.
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 adjustment bracket (4).
