Inquiry (采购产品): D&K CS429 power shear Hello- I'm a metal fabrication teacher with a problem I've inherited a Dreis & Krump CS 420 power shear. One of the nitrogen shock absorbers isn"t working properly and I don't have an operator manual for this peice of equipment. Could you help me with either problems? This equipment is critical in my program so any assistance will be greatly appreciated.
