For Replacement:

1.Slide auger outward against roll pin and align hole in shaft with hole in auger. The holes in the shaft for the roll pins and Shear Bolts line up.

2.Drive Shear Bolt through hole (if Shear Bolt was broken this will drive the remaining part from shaft).

3.Secure Shear Bolt with nut.

4.The Shear Bolts should not be overtightened to collapse the auger center tube to the auger drive shaft.

4.11 TIRE PRESSURE

Maintain the unit tire pressure at a maximum of 20 PSI (138 kPa).

4.12 ADJUSTMENTS

WARNING: ACCIDENTAL ENGINE START UP can cause death or serious injury. ALWAYS stop engine, remove key, wait for moving parts to stop and remove wire from spark plug before adjusting or servicing.

Discharge Chute Deflector

To adjust the drag force, loosen or tighten the two bolts to accomplish the desired drag.

Runners

Runners should be adjusted as conditions require. Raising or lowering runners controls distance scraper blade (auger/impeller housing) is held above surface being cleared.

1.Position unit on a hard, flat smooth level surface.

2.Adjust runners by inserting a spacer of desired thickness under center of scraper blade, loosen runner hardware, slide runners to flat surface

(Figure 7). Allow 1/8" (3 mm) between scraper blade and hard smooth surface. Allow 1-1/4" (30 mm) minimum between scraper blade and uneven surface(s).

3. Retighten hardware.

NOTE: Keep housing level by adjusting runners equally. Uneven runners make unit difficult to steer and results in uneven clearing.

Scraper Blade

IMPORTANT: Damage to auger/impeller housing will result if blade wears down too far.

Scraper blade is adjustable to compensate for wear.

To adjust scraper blade:

1.Tip unit back onto handlebar. Support the housing and loosen scraper blade nuts. With runners adjusted to their full up position, reposition scraper blade down, flush with runners. Tighten lock nuts. Readjust runners if necessary.

Discharge Chute

If chute does not stay in position while operating, tighten nut on carriage bolt at pivot point to increase tension on spring (Figure 8).

Smooth and easy rotation of properly lubricated chute with crank (without binding) is obtained by adjusting pinion and flat gear teeth so they mesh together.

Adjust, using adjustment slots in pinion bracket which is secured to chute strap.
