Automatic lubricating system, bleeding
WARNING
Risk of high pressure injection.
Oil or fuel leaks from high pressure hoses could cause serious
injury caused by high pressure injection.
If oil or fuel leaks from high pressure hoses or loose screws are
found, stop operations immediately and contact a qualified
service technician.
If the grease reservoir has been emptied below min. level before
new grease is filled and the system does not work as intended,
there is a risk that there are air pockets either in the pump unit or
in one of the main lines. The system has to be bled.

Paint finish maintenance
Machines used in corrosive conditions are more prone to rusting
than others. As a preventive measure it is recommended that the
paint finish should be maintained every sixth months.If there is
any doubt whether the conditions are corrosive or not, contact
your dealer.
At first clean the machine.
Apply Dinol 77B (or corresponding transparent waxy anti-rust
agent) at a thickness of 70–80 µm.
A protective layer of underseal Dinol 447 (or corresponding)
may be applied under the mudguards where mechanical wear
is expected.
