Hammer Usage

It is to Han Guang hammer to illustrate the proper use of hydraulic breaker. 1) Carefully read the operation manual hydraulic breaker to prevent damage to hydraulic hammer and excavator, and effectively operate them. 2) pre-operation inspection is loose bolts and connectors, as well as hydraulic lines for leaks. 3) Do not use the hydraulic breaker in hard rock pecking holes. 4) not fully extended or full reduction condition in the operation of the hydraulic cylinder piston rod hammer. 5) The intense vibration occurs when the hydraulic hose should stop the operation of the hammer, and check the accumulator pressure. 6) to prevent interference occurs between the excavator boom and hammer drill. 7) In addition to the drill bit, but not to hammer submerged in water. 8) Do not use hammer for lifting appliances. 9) Do not operate the excavator crawler side hammer. 10) hydraulic hammer hydraulic excavator or other construction machinery and equipment installation and connection, working pressure and flow rate of the hydraulic system of its host must meet the hydraulic breaker technical parameters, hydraulic breaker "P" port and host the high pressure connection, "A" port is connected to the host back to the oil. 11) hydraulic hammer hydraulic oils work best when the temperature is 50-60 degrees, the maximum should not exceed 80 degrees. Otherwise, it should reduce the load on the hydraulic breaker. 12) hydraulic breaker hammer working medium used, usually oil hydraulic system consistent with the host. General area recommended YB-N46 or YB-N68 anti-wear hydraulic oil, cold regions YC-N46 or YC-N68 hydraulic oil temperature. Hydraulic oil filtration accuracy no less than 50micro; m. 13) New and hydraulic repair broken hammer must be re-enabled when filled with nitrogen gas, the pressure 2.5, ± 0.5MPa. 14) must be lubricated with grease or calcium-based composite calcium based grease between the shank drill rod and the cylinder guide sleeve, and each time filling classes. 15) must first hydraulic hammer drill rod pressure when working on the rocks, and maintain a certain pressure after starting the hammer, not allowed to start in the floating state. 16) does not allow the hydraulic breaker when the crowbar, so as not to break drill rod. 17) When using the hydraulic breaker and fiber rod should be perpendicular to the face, so as not to produce radial force principle. 18) is broken when the object has occurred rupture or cracks begin immediately stop the impact hammer, to avoid harmful "Runaway." 19) hydraulic hammer should be used to stop long exhausted nitrogen, and into and out of the oil port seals, cut iron at high temperatures and -20 degrees below the ambient storage.
