6 Preparing the Machine for Storage.
Locate on a dry level surface. The machine should
be stored wherever possible so the rams are not
supporting any weight. The drive chains should
be lubricated with suitable roller chain lubricant before
prolonged periods of storage.
It is recommended that maintenance be carried out at
the end of the season, giving sufficient time to obtain
spare parts and/or carry out repairs if required.
The seed and fertilizer bins must be completely emptied
and cleaned.
Fit the cover to the bin.
