The ST 400 Pneumatic Borewell Machine is primarily designed for drilling water wells, agricultural irrigation wells, geothermal air conditioning holes, and other well types. It is particularly effective for water intake projects in mountainous areas and rock formations, delivering efficiency ten times higher than traditional rotary drilling rigs.

• Hydraulic automatic feeding mechanism improves drilling efficiency and reduces labor intensity
• Ball clip holding mechanism or hydraulic chuck enables rod changes without stopping operation
• Hole bottom pressure gauge provides real-time monitoring of drilling conditions
• Compact structure with concentrated controls for minimal footprint and easy mobility
• Lightweight design with strong decomposition capability for operation in plains and mountain areas

Proper maintenance is essential for maintaining the drilling rig's performance, service life, and reliability. Daily maintenance should include:

• Checking all fasteners for looseness
• Verifying spindle rotation flexibility
• Testing all control switches for normal operation
• Inspecting oiler condition, quantity, and quality
• Cleaning equipment after use to remove dirt and debris
• Applying rust inhibitor to any rusty parts
• Regularly cleaning the gas path filter screen
• Periodic disassembly and cleaning of motor housing components

Note: The aluminum alloy shell must be protected from falls, impacts, or pressure.
