Large CAF systems are equipped with red light and beep sounds if the hydraulic oil temperature gets too high. The alarms are set (generally at 250° F) to sound in time for the operator to either correct the high heat issue or to place the system in unload mode before the system suffers damage. Failure to react to the alarms may result in catastrophic damage to the CAF system. The hydraulic oil flash point is 309° F. Be sure to read the manufacturer’s instructions regarding the availability and function of any system alarms.
WARNING: during compression, there is NOT a lot of time between 250 & 309°F. Always be attentive to the temperature gauge – recognize problems anytime the temperature begins to increase above normal operating temperature. DO NOT WAIT FOR THE ALARM TO SOUND!!!
