WARNING
Refill with the same type of brake fluid that is already in the system. Mixing fluids may result in a harmful chemical reaction, lead-ing to poor braking performance.
CAUTION:
Ч Handle the ABS components with care since they have been accurately adjusted. Keep them away from dirt and do not sub-ject them to shocks.
Ч The ABS wheel sensor cannot be disas-sembled. Do not attempt to disassemble it. If faulty, replace with a new one.
Ч Do not set the main switch to “ON” when removing the hydraulic unit.
Ч Do not clean with compressed air.
Ч Do not reuse the brake fluid.
Ч Brake fluid may damage painted surfaces and plastic parts. Therefore, always clean up any spilt brake fluid immediately.
Ч Do not allow any brake fluid to contact the couplers. Brake fluid may damage the couplers and cause bad contacts.
Ч If the union bolts for the hydraulic unit have been removed, be sure to tighten them to the specified torque and bleed the brake system.
