Servicing and maintenance

NB

The pulleys are fitted with clamping elements held with seven screws which must be tightened
evenly in a diametrically opposite sequence.  To release, slacken all 7 screws using 3 of them to
jack clamp apart in the vacant holes.

Skids

When operating on abrasive soils, particularly in stubbles and similar conditions with thin ground
cover, excessive skid wear may be expected.  To provide extra protection and to prolong life of
the skids, special hard facing rods can be used.

Storage

At the end of the season before storing, thoroughly wash the machine, removing all traces of
grass and dirt. Great care must be taken  when washing with high pressure hoses, do not hold
the water jet close to the paintwork.

 Use steam cleaners with caution and be sure to remove all detergents to avoid any discolouring
or damage to paint.  Grease all grease points until fresh grease shows.  Store PTO shaft and
drive belts in a dry place.

Apply grease to all areas vulnerable to corrosion, in particular the chrome ram rods (or fully
retract).
