ACHTUNG:
CAUTION:
Clutch components rarely require disas-
sembly.
Therefore, always follow these preven-
tive measures:
• Never disassemble clutch components
unless absolutely necessary.
• If any connection on the hydraulic
clutch system is disconnected, the
entire clutch system must be disas-
sembled, drained, cleaned, properly
filled, and bled after reassembly.
• Never use solvents on internal clutch
components.
• Use only clean or new clutch fluid for
cleaning clutch components.
• Clutch fluid may damage painted sur-
faces and plastic parts. Therefore,
always clean up any split fluid imme-
diately.
• Avoid clutch fluid coming into contact
with the eyes as it can cause serious
injury.
First aid for clutch fluid entering the
eyes:
Flush with water for 15 minutes and get
immediate medical attention.
