Lightly Oil

A few drops of oil should be placed on wheel hubs occasionally to keep wheels turning freely.

Apply oil to pivot points of auger control peri- odically, wiping off any excess oil.

A couple of drops of light machine oil applied to upper end of auger control cable will assure free movement of cable through outside casing. Wipe off any excess oil.

Remove belt cover and lightly apply oil to the pivot point for idler pulley arm. BE CAREFUL NOT TO GET OIL ON BELT OR PULLEYS.
