HYDRAULIC BREAKER CONNECTION

The connection and maintenance of the hydraulic breaker is also a very important part. If you follow the instructions in detail, it will prolong the service life of the hydraulic breaker, reduce industrial waste, integrate resources, and avoid after-sales service.

1.1 PIPELINE CIRCULATION
Pipelines include pipelines, hoses, relief valves, stop valves,adapters,pipes fixed on main arm and slave arm connected by hose.The joints are firmly connected。Then close the stop valve,adjust relief valve to appropriate pressure. Butt joint of inlet and return hoses before load breaker. The pump drives the hydraulic oil to circulate for 30 minutes and then closes the stop valve,and check hydraulic oil and oil filter,ensure the cleanliness of the whole pipelines。Replace excavator hydraulic oil when necessary and recycle again。(Hydraulic oil should not leak to the ground)
1.2 CONNECTION
— Excavator hydraulic oil sufficient, clean, oil filter intact and clean. Ensure that the hoses connected firm with the mainbody after cleaning.
— Check the N2 gas pressure of back head and accumulator ,they are the required range。The valve adjuster nut must be locked.
—The back head and accumulator pressure must be checked regularly.,Too high or low pressure will damage the hydraulic breaker。

                                                                                       

—The inner bush 、front cover、tool pin and the shoulder of the tool are coated with appropriate amount of grease to facilitate the loading of the tool. When the tool is pressed in. A sufficient amount of grease is injected into the front head (5-10 shoot from the grease gun).
— All ready (the stop valve is open. the breaker is erect and the tool is pressed in). Testing breaker. The N2 gas pressure、relief valve and valve adjuster are adjusted according to the site conditions. These bolts and nuts must be locked again.。
— After stopping operation, the stop valve must be closed.
