Air filter element plugged with dust reducing compressor inlet flow
Compressor inlet valve worn or damaged reducing volumetric efficiency
Rotary head shaft seal worn allowing compressed air to bleed back
Air line leak at a coupling or fitting in the drill string air path
Track chain elongated beyond specification causing the chain to derail
Unequal track drive motor output from worn motor on one side
Track tension too loose from worn chain or incorrect tensioner adjustment
Roller or idler wheel bearing seized causing increased drive resistance on one side

How to diagnose compressor air pressure loss on a Sandvik DR / DI / DT drill rig
Low drill air pressure is usually a dirty air filter, worn compressor valves, or a leaking rotary head seal. Check the filter first because it is the fastest and easiest fix.
How to diagnose rotary head hydraulic faults on a Sandvik DR / DI / DT drill rig
Low rotary head speed means the rotation hydraulic motor or its control valve is restricting flow. Measure rotation circuit pressure and compare to the relief valve setting.
How to inspect track drive and undercarriage faults on a Sandvik DR / DI / DT drill rig
A rig that pulls to one side has a track tension or drive motor imbalance. Check and equalize track tension before looking at the hydraulic drive motors.
