9.1
Regular Preventative Maintenance
All maintenance, cleaning and repair operations must be performed with the machine firmly lowered to the
ground and detached from the tractor or with the PTO disconnected, engine switched off and starting key
removed. For any repairs or maintenance that requires access from underneath, the machine should be firmly
and safely raised and propped using suitable purpose designed supports capable of bearing the machines full
weight. Care should be adopted at all times when working with or under a raised machine.
Daily maintenance operations facilitate the removal of mud or other material from rotating parts (bearing, pins
etc.) in order to avoid rust and possible seizures. This helps to prolong the service life of the machine.
