Motion Systems INTRODUCTION OIL VISCOSITY ACCORDING TO TEMPERATURE Read this instructions carefully before installation. All operations must be carried out by qualified personnel following the instructions. The user must periodically inspect, based on the conditions of use and the substances used, the presence of corrosion, dirt, the state of wear and correct function of the valves. HYDRAULIC FLUID Use only mineral oil (HL, HLP) according to DIN 51524. Use of other different fluids may damage the good operation of the valve. VISCOSITY The oil viscosity must be in the range of 10 mm2/s to...
