Hydraulic oil

The suitable replacement period for hydraulic oil in a sealed tank system is 2000 hours, and more often if the hydraulic oil is contaminated with water or other external materials or subjected to abnormal operating conditions.

As a general recommendation, the 10µ inlet oil filter should be replaced every spring or every 1500 hours (whichever occurs first) on a sealed tank system, or in an open tank system with an air filter fill cap. The oil filter should be replaced every 500 hours.

Heat Exchanger

The heat exchanger core and fins are kept clean at all times for maximum cooling and system efficiency, and the exterior of the heat exchanger is checked daily for blockages and cleaned as needed.

Application:

Mixer truck: concrete mixer truck, cement mixer truck;

Coal mining machinery: scraper;

Industry: pharmaceutical machinery;

Transport vehicles: road rollers, concrete pump trucks, stabilized soil mixers
