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.
Chute Crank
Smooth and easy rotation of properly lubricated chute
with crank (without binding) is obtained by adjusting
clearance between worm and discharge chute gear
teeth (Figure 8).
To adjust, loosen nut on bracket supporting worm,
position worm to fully engage (without binding), gear
teeth on discharge chute and tighten nut.
To prevent discharge chute from rotating by itself when
unit is being operated, tighten jam nuts on end of crank
rod to put increased tension on worm gear.
