Control of screw connections subject to intense vibration;
Control of retaining pins integrity;
Control of rubber pipes;
Control of tie rods integrity;
Control of tool clearance inside the cavity;
Control of tool wearing, checking its minimum diameter before substitution of tool;
Control of wearing bush diameter;

Oil viscosity is 15c St.;
Molybdenum disulfide grease resisting to high temperature;
Gas: normal nitrogen, purity at 99,8%;
Control oil filter: the return pipe of hydraulic system should have an oil filter;
Constant control of oil pressure temperature for hydraulic mechanism (not over 80° C). If the tank reaches a high temperature you must install a heat exchanger. Fill the accumulator with nitrogen only and make sure that in the accumulator you should not use other kinds of gas (oxygen for instance). Before opening the accumulator it’s extremely important to make sure that there is no pressure at all through the accumulator screw.
