  The new low-kickback, low-vibration 3/8" Picco
  Micro Comfort 3 chain (3/8" PMC3) is designed for
  low kickback tendency, a low level of vibrations and
  high cutting performance.                                                1                        1

The depth gauge on the 3/8" PMC3 is lowered in
exactly the same way as on the Picco Micro chain.
When the depth gauge has been repositioned by
roughly .016 in (0.4 mm), the upper part of the
humped drive link (with service mark) must be
lowered together with the depth gauge of the cutter.
The depth gauge setting is identical with that of the
Picco Micro chain.
