  1. Handling/working precautions
    CAUTION:
    • Be careful not to spill the brake fluid. Brake fluid spilled on the vehicle body will damage the paint surface; wash it off with water and wipe clean quickly if spilled.
    • Be sure to use FMVSS No. 116 DOT3.
    • Cover the bleeder plug with cloth to prevent clutch fluid from being splashed on surrounding parts when loosening the plug.
    • Avoid mixing clutch fluid of different brands to prevent fluid performance from degrading.
    • Be careful not to allow dirt or dust to enter the reservoir tank.
