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.
