Terex SKSS-15 Series Infinity Blasthole Drill Service Manual

The Terex SKSS-15 Infinity Drill is built for deep blasthole drilling with consistent penetration and torque delivery. This Service Manual exposes the behavior of the rotary head, air delivery system, mast structure, and hydraulic feed chain. Its detailed schematics guide technicians through diagnosing reduced drilling efficiency or air pressure instability.

Applications & Use Cases

Servicing the drill’s air compression and delivery components
Rebuilding rotary head assemblies
Detecting mast misalignment that affects drilling accuracy
Maintaining hydraulic feed cylinders and control valves
Managing lubrication flow during high-duty operation

FAQ
Does the manual provide rotary head torque specs?
Yes, including allowable wear limits.

Is it helpful for deep-drilling maintenance cycles?
Absolutely. It covers all major wear zones.

Safety Note
Always isolate the air system and secure the mast before performing repairs.
