Do not use sharp objects to clean the cooler. It could be damaged.
Avoid creating clouds of dust.
1. Carefully remove the filter mat from the retaining frame.
2. Dry brush the oil and air coolers and use a vacuum cleaner to suck up the dirt.
3. Carefully insert the filter mat in the retaining frame.
