Main Maintenance Operations; Changing The Air Filter; Checking Brake And Clutch Fluid Level - Monster 659 Owner's Manual

Main maintenance operations

Changing the air filter

Important
Have the air filter maintenance performed at a Ducati
Dealer or authorised Service Centre.

Checking brake and clutch fluid level

The levels should not fall below the MIN marks on the
respective reservoirs.
If level drops below the limit, air can get into the circuit and
make the system ineffective.
Brake and clutch fluid must be topped up and changed at the
intervals specified in the scheduled maintenance table
reported in the Warranty Booklet; please contact a Ducati
Dealer or authorised Service Centre.
Important
It is recommended that all brake and clutch hoses be
renewed every 4 years.
Clutch system
If the control lever has excessive play and the transmission
snatches or jams when engaging a gear, this indicates that
air is in the circuit. Contact your Ducati Dealer or authorised
Service Centre to have the system inspected and air drained
out.
Warning
The level of clutch fluid tends to increase in the
reservoir as the friction material on the clutch plates wears
out. Do not exceed the specified level (3 mm above the
minimum level).
