13.7 SCRAPER BLADE
IMPORTANT:
If scraper blade wears too far auger/
impeller housing may be damaged.
Scraper blade is adjustable to compensate for wear.
To adjust scraper blade, raise and block Sno-Thro
securely. With runners adjusted to their full position,
loosen lock nuts retaining scraper blade, reposition it
down, (Flush with runners) and tighten lock nuts.
13.8 RUNNERS
Runners should be adjusted as conditions require.
Raising or lowering runners controls distance scraper
blade is held above surface to be cleared.
When operating unit on gravel surface, lower runners
so that the housing will not pick up gravel. On concrete,
black-topped, or packed snow surfaces raise runners
so that the scraper blade scrapes clean. To reduce
tendency of housing to ride up over heavy, wet, or
hardpacked snow, remove runners and install in their
narrow edge down position.
To adjust runners, place unit on a flat level surface and
insert a spacer under center of scraper blade that will
provide desired clearance. loosen runner hardware,
raise or lower runners to surface unit is resting upon,
and tighten hardware.
NOTE:
Uneven rear tire pressure or runner adjustment
will result in uneven clearing.
