the auger housing (4). To adjust the height of
the skids, see “How To Adjust The Height Of
The Skids” in the Maintenance section.
How To Set The Length Of The Cables
The cables were adjusted at the factory and no

after the handles are put in the operating
position, the cables can be too tight or too loose.
If an adjustment is necessary, see “How To
Check And Adjust The Cables” in the Service
And Adjustment section.
