Trouble Shooting and Maintenance Hints

Drilling rock is a very difficult process and during drilling some problems with hammers might be faced. In order to avoid such problem the following precautions are taken:

Compressor Output is Checked for

	Temperature & altitude are adjusted
	Air pressure is checked with pressure gauge
	Air filters are checked
	Minimum Level of rock oil is maintained

Drill Rods are Checked for

	Air leakage’s throughout
	Pressure loss in hose

Weight on bit is checked for

	Feed cylinder dropping
	Proper rotation & feed

Control tube is checked for

	Correct diameter and height
	Chips at internal diameter
	Burrs on outer diameter

Check valve is checked for

Proper seating

Level of rig is checked for

	Level jacks leakage
	Hydraulic pressure dropping at valve end

Recommendations
Observe closely on hydraulic system elements and detect any leaks in the system, even though it may be very small, take appropriate action to correct them (simply by tightening the joints or reporting to the service engineer) Leaks on the radiator should be observed daily otherwise this will lead to engine failure.
