Clean the hydraulic fluid side of the cooler
1. Disassemble the blast oil cooler to find the degree of contamination.
If contamination is moderate, connect the oil side to a closed cleaning system with a pump and
a filter.

Ethylene perchlorate detergent can be used. Pump the detergent through the blast oil
cooler for10 minutes.
If contamination is very bad, use an oil carbon detergent. Rinse cleaned surfaces for30 minutes.
2. Use compressed air to remove remaining detergent.
3. Rinse the blast oil cooler with operation or equivalent oil.
