Operation Guidelines
  • Conduct a 10-20 second no-load test run before starting to ensure smooth operation
  • Never touch rotating drill rods or bits during operation
  • Maintain uniform pushing force to avoid sudden overload
  • Reduce thrust and lower speed when encountering hard rock or stuck drilling
  • Never replace drill rods or repair components while the machine is operating
Safety Prohibitions
  • Prohibited in flammable/explosive environments
  • Keep exhaust ports away from flammable materials
  • Avoid wet-hand operation in humid environments
  • Ensure proper ventilation during underground operations
  • Never use for non-drilling operations
  • No unauthorized modification of core components
  • Professional maintenance required every 500 hours or 6 months
