Verify all connections are tight before proceeding. Fill the hydraulic reservoir with the recommended fluid type and grade.

Step 2: First-Time User Guide

Power on the system using the main switch on the control panel. Familiarize yourself with the joystick controls for rotary speed, feed rate, and mast angle. Run the hydraulic system at idle for a few minutes to circulate fluid and check for leaks. Engage the rotary head at low speed to confirm smooth operation.

Step 3: Core Functions and Daily Use

For standard borehole drilling, align the mast vertically using the control panel. Attach the first drill rod and bit. Begin rotation at moderate speed while applying gradual downward feed pressure. Monitor the torque gauge to avoid overloading the system. As you buy hydraulic rotary drilling rig, expect a learning curve with the feed control, but the system responds predictably once you understand the hydraulic feedback.

Step 4: Advanced Techniques

When encountering hard rock layers, switch to DTH hammer mode if your model supports it. Adjust the feed pressure to match the formation hardness. For deep wells beyond 300 meters, consider using a drilling mud system to stabilize the borehole. Experienced operators can fine-tune the rotary speed to match specific rock types for faster penetration.

Step 5: Maintenance and Care

After each days use, clean the mast and rotary head of mud and debris. Check hydraulic fluid levels and inspect hoses for wear. Grease all fittings according to the maintenance schedule. Store the rig under cover when not in use to protect hydraulic components from weather. For a detailed care routine, check our drilling rig maintenance guide.

Step 6: Troubleshooting Common Issues

If the rotary head stalls, reduce feed pressure immediately and check for binding in the borehole. Slow penetration often indicates dull drill bits or insufficient weight on the bit. Hydraulic system overheating usually means the fluid level is low or the cooler is blocked. If the mast drifts during operation, tighten the locking valves on the hydraulic cylinders.
