Technical Guides
Technical knowledge that holds up on site, with its sources stated.
This section is not a blog. Blog posts are dated and go stale; these pages are written to be referred back to and kept up to date. Each guide answers one question, deep enough to be useful on site.
Model-specific numbers — nitrogen pressure, tightening torque, wear limits — are deliberately not printed here. Those values differ by breaker model, and a wrong figure damages the machine. The texts explain the method and the diagnosis, and point you to your breaker manual, or to us, for the figure itself.

Faults and diagnosis
Why does breaker nitrogen pressure drop, and how do you tell?
A breaker with low nitrogen pressure strikes weakly, drops in blow rate and runs unusually hot at the back head. Pressure falls for three reasons: seals ageing and leaking, the slow natural loss of gas over time, and damage to the diaphragm or accumulator.
Read →Bushing wear: why replacing the seal alone does not fix it
When a breaker leaks oil, the usual response is a new seal. But the seal is often the symptom, not the cause: once the bushing wears, the tool no longer runs on centre, the seal takes an uneven load and the new seal fails within weeks.
Read →Piston surface damage: the chain that starts with dirty oil
Longitudinal scoring on a breaker piston is almost never a material fault; it is caused by hard particles in the hydraulic oil being crushed between piston and cylinder. The chain begins with dirty oil, continues as scoring, accelerates when the seal is cut, and then feeds itself as the growing leak draws in more dirt.
Read →Tie rod torque: early signs of loosening and the right tightening order
Tie rods clamp the three main body parts of a breaker together and are stretched by every blow. When one loosens, its load shifts to the others, micro-movement begins at the body joints and the chain usually ends in a broken rod.
Read →Hydraulic oil contamination: the invisible cause behind most failures
Scored pistons, sticking valves, short seal life and overheating look like separate failures, but they usually share one root: solid particles, water and air in the hydraulic oil. Dirt normally enters through fittings left open at a tool change, a blocked tank breather, and swarf left inside new hoses.
Read →Reading the sound of a breaker: what each noise is telling you
Most breaker faults can be noticed by ear before any instrument comes out. A healthy breaker produces an evenly spaced, solid, single-body sound.
Read →Run-in after repair: how to work a rebuilt breaker in its first hours
The first working hours of a rebuilt breaker shape the months that follow. Until new bushings, seals and piston surfaces bed in, friction and heat run higher than normal.
