1. performance of pneumatic leg rock drill:
YT28 type pneumatic leg rock drill adopts gas-water linkage, rapid return of air leg, and air pressure adjustment. The control handle is concentrated with the handle body, the mechanism is novel and the operation is convenient. The sound-absorbing cover with the belt can effectively reduce the noise and change the exhaust direction at will, and improve the working conditions on the spot. Compared with the same type of rock drill: lightweight, has low noise, high efficiency, and good economic effect.
2. Precautions for use:
1. Since the machine is filled with anti-rust oil when it leaves the factory, and the transportation and storage will inevitably invade dust, the new machine must be disassembled and cleaned before use.
2. When connecting the air and water pipes, blow off the dirt in the pipes first, so as to prevent the sundries from entering the machine and damaging the machine parts. the
3. Before starting the machine, it is necessary to carefully check whether the joints of the threads and snap rings are reliable and whether the operating handles are flexible; the lubricating device must be filled with lubricating oil, and the oil valve must be adjusted. During the working process, check or fill oil into the lubricator every hour. Operation without oil is strictly prohibited! the
4. When the machine is started, the trolley should be started first, and the whole car should be gradually driven to drill rock while the jacking force of the air legs is gradually increasing. Do not run the whole car suddenly when the thrust of the air leg is at its maximum, let alone run the whole car idling for a long time to avoid scratches and damage to the parts. When pulling out the brazing, it is advisable to drive half the car.
5. After the work is finished, the water pipe should be closed first, and then run for a while to blow off the residual water droplets in the machine to prevent parts from rusting.

Technical Security:
1. Before turning on the compressed air, the control handle and the pressure regulating valve handle should be returned to zero; before driving, check whether the threads and snap rings are loose, so as to prevent accidental injury during work. the
2. In the process of rock drilling, special attention should be paid to the sudden breakage of the drill rod to prevent industrial accidents.
