IMPORTANT: DO NOT allow grease or oil to get on the
belts.
NOTE: Apply Ariens Hi-Temp Grease or equivalent to
the lubrication fittings. See SERVICE PARTS on
page 20.
Sno-Thro should be lubricated (Figure 10) at beginning
of season or every 25 operating hours.
Auger Shaft
NOTE: To grease auger shaft, remove shear bolt nuts,
and shear bolts. Apply grease at the grease zerks and
then turn the auger shaft. Replace shear bolts per
instructions in Shear Bolts on page 15.
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 housing
and loosen nuts retaining blade.
2. Adjust runners to fully raised position (housing
closest to ground).
3. Reposition scraper blade flush with runners and
tighten lock nuts.
RUNNERS
Runners should be adjusted as conditions require
(Figure 11).
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.
Allow 1/8 in. (3 mm) between scraper blade and
hard smooth surfaces. Allow 1-1/4 in. (30 mm)
between scraper blade and uneven or gravel
surfaces. Retighten hardware.
NOTE: Keep housing level by adjusting runners
equally.
SHEAR BOLTS
IMPORTANT: Use only Ariens shear bolts for
replacement. Use of any other type of shear bolt may
result in severe damage to unit.
Occasionally a foreign object may enter the
auger/impeller housing and jam the auger, breaking
shear bolts (Figure 12) which secure the auger to the
shaft. This allows auger to turn freely on the shaft
preventing damage to gear drive.
