The pneumatic 350 drilling rig serves as core equipment for drilling small and medium-sized hard materials, featuring four key characteristics: high efficiency, flexibility, safety, and economy. Its combination of efficient power, scene adaptation, safety durability, and cost advantages makes it the preferred choice for mining, geological exploration, and construction applications.

• Equipment inspection: Confirm drill rod and bit are securely installed without bending or wear; check tracheal connections for leaks; add sufficient lubricating oil.
• Gas source debugging: Connect air compressor, adjust pressure to 0.4-0.63MPa, discharge accumulated water, ensure clean and dry gas source.
• Environment and protection: Clear work surface obstacles; operators must wear safety helmets, goggles, and non-slip gloves.

• Start the drilling rig: Slowly open air supply valve, let rig idle for 10-20 seconds, check for smooth operation without abnormal noise.
• Start drilling: Align drill bit with hole position, apply pushing force gradually, adjust speed based on material hardness.
• Process monitoring: Maintain vertical drilling direction; if stuck, reduce thrust and speed, reverse operation before re-drilling.

• Shutdown steps: Reduce thrust, close air source valve, wait for rig to stop, remove drill rod and bit, clean surface dust.
• Equipment maintenance: Discharge residual air, check for loose or damaged components, store in dry place.
