Mechanized construction companies, engineering machinery technical condition is good or not is a direct factor in business whether normal production. On hydraulic transmission engineering machinery, the normal operation of the hydraulic system is a major sign of their good technical condition. Qualified hydraulic oil is to protect the reliable operation of the hydraulic system, proper maintenance is essential for reliable operation of the hydraulic system. To this end, according to the work they practice on safeguarding the general operating environment of a hydraulic system for rough discussed. Select the appropriate hydraulic oil hydraulic oil in the hydraulic system plays transmit pressure, lubrication, cooling, sealing the role of small excavators price list, the inappropriate choice of hydraulic fluid is a hydraulic system failure and durability early decline. When selecting hydraulic oil grade should be random "manual" in the provisions of the special circumstances need to substitute oil, we should seek the same performance as its original performance grades. Different brands of hydraulic oil can not be mixed use, to prevent hydraulic oil to produce a chemical reaction, the performance changes. Dark brown, white, smelly oil hydraulic oil is bad, you can not use. Long-term storage Note - hammer should be stored in the temperature change is not the place. - Drill rod should be removed and put to internal nitrogen (N2) - end of the piston to be coated with butter, drill rod bushing should be coated with anti-rust agent - when the price can not be lubricated mini excavator, drill rod must shrink from easy piston into the cylinder inside. - Connect excavator / loader and excavator connector body member price, application terminal cap sealed to prevent dust entering the tubing. - Hammer is best placed vertically, if not, the hammer should put in place the wood on the ground. - If the hammer put more than six months or more on the wooden bar, before operating all corrosion inspection seals and bolts inside the fuel tank. 1) storage method cyclical measures every three months to seal with good working conditions, to put the hammer turning every six months to check all internal corrosion cylinder seals and bolts 2) cyclical measures before work every three months to check seal every six months to check seals and corrosion Note: If the hammer resting on the side of the wood more than six months or more, before operating all corrosion inspection seals and bolts inside the fuel tank.
