Piston and Striker O-Ring Kit
The pneumatic seal between the reciprocating piston and the striker is maintained by specialized O-rings. When these seals wear or harden, the air cushion loses pressure (blow-by), which prevents the striker from reaching its designed terminal velocity before hitting the anvil, resulting in weak impact force.

Hilti Performance Grease (Pneumatic Chamber)
Electro-pneumatic hammers require specific low-viscosity grease to allow the striker to slide freely. If the grease becomes contaminated with concrete dust or thickens due to thermal oxidation, it creates a vacuum effect or mechanical drag that slows the striker, significantly dampening the hammering power.

Rotary Hammer Striker (Knocker)
Repeated metal-on-metal impacts can lead to work-hardening or deformation of the striker's striking face. If the striker is chipped or if the surface finish is compromised, it can cause erratic movement within the cylinder and inefficient energy transfer to the drill bit.
