Runner And Scraper - Ariens 939 SNO-THRO 939001 Service Manual

9.5 RUNNER AND SCRAPER

CAUTION: Adjust auger/impeller housing
height to clear gravel or crushed rock
surfaces.
Runners should be adjusted as conditions require
(Figure 27). Raising or lowering runners controls
distance scraper blade is held above surface being
cleared.
When operating machine on gravel surface, lower
runners so the housing will not pick up gravel. On
concrete, blacktopped or packed down snow surfaces,
raise runners so that scraper blade scrapes clean.
Position unit on a flat level surface. Adjust runners by
inserting a spacer of desired thickness under center of
scraper blade, loosen hardware, slide runners to flat
surface and retighten hardware.
NOTE: Above method keeps housing level by adjust-
ing runners equally. Uneven runners make machine
difficult to steer and results in uneven clearing.
