Function Selector Kit
Fine masonry dust penetrates the selector's radial seal, contaminating the internal lubricant and creating a binding paste. This prevents the eccentric cam from properly translating the shifter fork into the chiseling position. Replacing the knob and its integrated seal is required to restore mechanical leverage and environmental sealing.

Internal Shifting Fork
The internal shifting fork is the mechanical linkage that moves the gear synchronization rings between rotation and percussion modes. If the selector knob was forced while bound by debris, the fork's engagement pins often shear or bend, resulting in the tool being unable to lock into the 'C' mode despite the knob turning.

Hilti Turmopol Grease 40ml
The rotary hammer's internal 'knocker' and shifting mechanisms rely on specific thixotropic grease to operate under high-frequency vibration. Thermal degradation or particulate contamination of this lubricant causes it to 'gum up,' physically obstructing the gear movement required for mode changes.
