Tips Drawing
Before replacing high pressure hoses, either hydraulic or pneumatic, always shut the pump or pumps down, lock out and tag the equipment. Check the hose or hoses to be replaced by twisting or squeezing them to see if the pressure has been relieved, or by another method suitable to the hose being used. If pressure is still in the hose or hoses, take appropriate measures to relieve the pressure before loosening the fittings.
