PRECAUTIONS

Precautions

NGCL0001

I Recommended fluid is brake fluid “DOT 3”. I Never reuse drained brake fluid. I Be careful not to splash brake fluid on painted areas. I When removing and installing clutch piping, use Tool. I Use new brake fluid to clean or wash all parts of master

cylinder, operating cylinder, and clutch damper.

I Never use mineral oils such as gasoline or kerosene. It will

ruin the rubber parts of the hydraulic system.

WARNING:

After cleaning the clutch disc, wipe it with a dust collector. Do not use compressed air.
