BLEEDING THE HYDRAULIC CLUTCH
SYSTEM
WARNING
@
Bleed the hydraulic clutch system when-
ever:
• the system was disassembled,
• a clutch hose was loosened or removed,
• the clutch fluid level is very low,
• clutch operation is faulty.
@
NOTE:
@
• Be careful not to spill any clutch fluid or allow
the clutch fluid reservoir to overflow.
• When bleeding the hydraulic clutch system,
make sure there is always enough clutch
fluid before applying the clutch lever. Ignor-
ing this precaution could allow air to enter the
hydraulic clutch system, considerably length-
ening the bleeding procedure.
• If bleeding is difficult, it may be necessary to
let the clutch fluid settle for a few hours.
Repeat the bleeding procedure when the tiny
bubbles in the hose have disappeared.
