9.5 RUNNERS
Runners should be adjusted as conditions require
(Figure 22). Raising or lowering runners controls
distance scraper blade is held above surface being
cleared.
When operating machine on gravel surface, lower
runners so that housing will not pick up gravel. On
concrete, blacktopped or packed down snow surfaces,
raise runners so that scraper blade scrapes clean. To
reduce tendency of housing to ride up over heavy wet
or hard-packed snow, remove runners and re-install
with the narrow edge down.
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.
CAUTION:
Adjust auger/impeller housing
height to clear gravel or crushed rock
surfaces.
