2 Assembly
Each CONCEPT X punch consists of four components: punch body, slider, anterior han-
dle element, and screw. Only components belonging to the same unit may be assem-
bled, with the exception of the screw which fits all punches. Component compatibility can
be verified by means of the identification number (pos.5) that is marked on all compo-
nents (except the screw).
NOTE: Before assembling the contact areas have to be lubricated.
a) Place the slider with the spring (pos.6) on the milled groove (pos.7) in the punch
body, and the front guide of the slider (pos.8) on the guiding rail (pos.9) of the punch
body at the same time.
b) Slowly push the slider to the front until it is flush with the rear end of the punch body.
Hold this position.
c) Slowly push the handle element completely into the matching recess in the punch
body.
d) Screw the hex head screw counterclockwise into the provided screw hole using the
supplied screwdriver TXX-0X. Tighten the screw. ATTENTION: Do not over-tighten.
e) The punch is ready for use after a functional test.
The screwdriver TXX-0X can be cleaned with warm water and a mild detergent. Hot
water and steam sterilisation at 134°C will destroy the screwdriver.
