!WARNING:
Brake fluid is hygroscopic and should never be stored in an un-sealed container. The presence of water in the braking system will cause vapour locks and increase the possi-bility of brake fade along with pro- moting corrosion within the braking system. The brake fluid must bechanged at the specified time or mile- age interval to ensure continued safe operation of the system. Brake fluid will cause rapid and serious damage to paintwork. If accidental spillageoccurs, the affected area must be rinsed with water immediately. Do not allow brake fluid to come intocontact with the eyes or to be in- gested and ensure that fluid is safely stored away form the reach of chil-dren. SG140A1-E AIR CONDITIONING SYSTEM MAINTENANCECondenser Ensure that the condenser is periodi- cally inspected and that accumulations of dirt, dead insects and leaves etc, areremoved to ensure that the efficiency of the system is not impaired. Care must be exercised to ensure that the con-denser fins are not damaged during cleaning.
