Seals Assembling
When mounting the Oil Seals put crease between the inner lips of the seals before pushing the stanchions in!
Important : Use a suitable tool to press the Oil Seal verticaly in!! If you don’t do that, the metal skeleton will bend.

Seals ‘Break-in Period’
“Some forks may require 5-10 hours of use before the fork fully breaks-in. After the bushings, seals, and other parts have matched to each other, the fork will move smoother. The tight tolerances make the fork last longer and work better.” (original text from Marzocchi Bomber Technical Information (2000) )

Knob / Dial Installation Instructions
Please glue the little screw of the dials with a little bit of middle hard screw glue. And use heat if you want to take it off than.

Sticker Instructions
Please use the sticker only in conditions >=20°C environment to make sure the glue will work and make the tubes oil- and grease-free using isopropanol etc.

“Hallo Marcus, 
die Gabel ist angekommen und ich bin begeistert! Vielen Dank auch für die zusätzlichen Dichtringe und die Gummibärchen!!!
Wie kann ich die Dämpfung etwas weicher einstellen und welche Funktion haben eigentlich die Einstellschrauben jeweils auf den Standrohren?
Beste Grüße,
