How to Check and Add Fluid
Visually check the brake/clutch fluid
reservoir to make sure the fluid level
is at the MIN (minimum) line on the
side of the reservoir. The brake/
hydraulic clutch fluid system should
be closed and sealed.
Do not remove the cap to check the
fluid level or to top off the fluid level.
Remove the cap only when
necessary to add the proper fluid
until the level reaches the MIN line.
