WARNING
• Use only the designated clutch fluid. Other
clutch fluids may cause the rubber seals to
deteriorate, causing leakage and poor
clutch performance.
• Refill with the same type of clutch fluid that
is already in the system. Mixing clutch flu-
ids may result in a harmful chemical reac-
tion, leading to poor clutch performance.

• When refilling, be careful that water does
not enter the clutch fluid reservoir. Water
will significantly lower the boiling point of
the clutch fluid and could cause vapor lock.

spilt clutch fluid immediately.

BLEEDING THE HYDRAULIC CLUTCH
SYSTEM
EWA13000
WARNING
Bleed the hydraulic clutch system whenever:
• the system was disassembled,
• a clutch hose was loosened or removed,
• the clutch fluid level is very low,
• clutch operation is faulty.
TIP
• Be careful not to spill any clutch fluid or allow
the clutch master cylinder reservoir to over-
flow.
• When bleeding the hydraulic clutch system,
make sure there is always enough clutch fluid
before applying the clutch lever. Ignoring this
precaution could allow air to enter the hydraulic
clutch system, considerably lengthening 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.
1. Remove:
• Clutch release cylinder cover "1"
