Ariens Sno-Thro 921012 - Manual (Page 26)

GB - 26
GENERAL LUBRICATION
IMPORTANT: Wipe each fitting clean before
and after lubrication. Do not wipe gearcase
filler plug; wiping the gearcase filler plug may
remove thread sealant and cause leaks.
IMPORTANT: DO NOT allow grease or oil to
get on friction disc, friction plate or belts.
NOTE: Apply Ariens Hi-Temp Grease or
equivalent to the lubrication fittings. See
SERVICE PARTS on page 37.
Sno-Thro should be lubricated (Figure 26) at
beginning of season or every 25 operating
hours.
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 skid shoes to fully raised position
(housing closest to ground).
3. Reposition scraper blade flush with skid
shoes and tighten lock nuts.
SKID SHOES
Skid Shoes should be adjusted as conditions
require (Figure 27).
1. Position unit on a hard, flat, smooth level
surface.
2. Adjust skid shoes by inserting a spacer
of desired thickness under center of
scraper blade, loosen skid shoe
hardware, slide skid shoes 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.
