COOLER

551 878 41B COOLER This COOLER is an essential heat exchanger for the rig's hydraulic or compressor oil circuit. Its main job is to dissipate the heat generated during operation, keeping the oil within its optimal temperature range. By maintaining the correct oil viscosity, it protects critical components like hydraulic pumps, motors, and the rock drill's internal mechanisms from accelerated wear.

Located within the main power pack or compressor assembly, this component is vital for consistent drilling performance. If the oil gets too hot, the system can become sluggish, and you might notice a drop in the drifter's impact energy or slower boom movements. A properly functioning COOLER ensures the machine delivers full power throughout a long shift, preventing performance degradation caused by thermal issues.

Common signs of a failing COOLER include high-temperature warnings on the control panel, visible oil leaks from the core, or fins that are heavily clogged with dust and grime. Regularly clean the cooling fins with compressed air to maintain good airflow. If the unit is damaged or leaking, it should be replaced promptly to prevent serious damage to the entire hydraulic system.
