Adjusting the Skids
Check the skids to ensure that the auger does not
contact the paved or gravel surface. Adjust the skids
as needed to compensate for wear.
If the pavement is cracked, rough, or uneven, adjust
the skids to raise the poly edges. For gravel surfaces,
adjust the skids further down to prevent the machine
from picking up rocks.
Lowering the Skids
1.
Park the machine on a level surface.
2.
Shut off the engine, remove the key, and wait
for all moving parts to stop before leaving the
operating position.
3.
Loosen the nuts that secure both skids to the
auger sides until the skids slide up and down
easily.
Important:
Support the auger blades above
the ground using the skids.
4.
Move the skids down until they are even with
the ground.
5.
Firmly tighten the nuts that secure both skids
to the auger sides.
