This Service Manual explains the internal percussion mechanism, rotary drive behavior, hydraulic flow control, feed system alignment, and lubrication networks. It’s an essential resource for diagnosing weak impact force, overheating, reduced penetration rate, or rotary torque instability.
Applications & Use Cases
-
Servicing percussion pistons, liners, sleeves, and seals
-
Diagnosing hydraulic pressure drops or unstable rotation
-
Aligning feed systems for straight-hole drilling
-
Overhauling lubrication and cooling pathways
-
Conducting major rebuilds after long drilling cycles
FAQ
Does it include percussion output specifications?
Yes. Impact energy and operating tolerances are documented.
