This is a advanced,reliable, durable and energy-saving well drilling machine, which has high operating efficiency, low energy consumption, good economic benefit, simple machine structure, stable operation, large lifting power, and can meet all kinds of operation requirement. Preparation work before drilling 1. Check whether all air and oil hoses are damaged and make sure all hose connections are safe and reliable. 2. Check whether the hydraulic oil in the oil tank is sufficient and whether the oil injector has oil. 3. check whether the lubrication of the lubrication parts is appropriate. 4. check the slide frame and remove debris. 5. check the fixation of the rotary device on the mounting plate, whether the connection between the mounting seat plate and the slide frame is intact. 6. check the air compressor air pressure value, the minimum pressure should not be less than 0.10Mpa; 7. Blow out the debris in the main air duct and connect it reliably to the fitting of the air inlet pipe of the drilling rig. 8. check that the hoses are completely tied to the safety valve before opening the air inlet ball valve. 9. check that all hoses are in good condition and that the coupling is tight and reliable. 10. Adjust the oil injector.
