Service Repair Kit (O-Rings and Seals)
The pneumatic impact mechanism relies on a dynamic air seal created by the piston O-ring. Over time, friction and heat cause the rubber to flatten or harden, leading to 'blow-by' where air escapes rather than compressing to drive the striker. Replacing the seal kit restores the airtight compression chamber necessary for the hammer action to engage.

Striker / Ram Assembly
If the seals are intact but impact is still absent, the striker may be physically jammed or the internal bore of the striker may be scored. This component is the mass that actually travels within the cylinder to deliver the blow; any mechanical deformation prevents it from reciprocating even under full air pressure.

Bosch Hammer Grease (FTV5)
Electro-pneumatic hammers require a specific viscosity grease that allows the striker to move freely while maintaining a vacuum seal. Using standard grease or allowing the factory grease to dry out creates a 'suction' or 'stiction' effect that prevents the striker from cycling, effectively disabling the hammer function while the drill continues to rotate.
