Carrier hydraulic oil S 83 STD
The damage caused by hydraulic oil impurities in the carrier and hammer circuits:
1. The working life of the pumps and other components is significantly shortened.
■ Rapid wear of parts.
■ Cavitation.
2. Wear of cylinder and gaskets.
3. Reduced hammer efficiency.
■ Accelerated wear of moving parts and seals.
■ Danger of piston seizing up.
■ Oil leakages.
4. Shortened working life and reduced lubricating capability of oil.
■ Oil overheats.
■ Oil quality deteriorates.
■ Electro-chemical changes in hydraulic oil.
5. Valves do not function properly.
■ Spools bind.
■ Rapid wear of parts.
■ Blocking of small holes.
Note: Component damage is only a symptom. The trouble itself will not be cured
by removing the symptom. After any component damage due to impurities in the
oil, the entire hydraulic system has to be cleaned. Dismantle, clean and reassemble
the hammer and change the hydraulic oil.
