7. Adjusting the AC-380 or AC-381 Tilt knob
To fix the AC-380 or AC-381 in position, take the barrel of the knob and
rotate it counter clockwise while keeping pressure in the knob towards
the front standard. Use the supplied 2mm (for AC-380) or 1,5mm (for
AC-381) Allen key to retighten the tilt knob fixation bolt.
Note:
The barrel of the AC-380 and AC-381 is eccentric and you can adjust the
feel of the knob until it meets your demands. To adjust the knob repeat
the steps noted above and keep in mind that rotating the barrel counter
clockwise applies more pressure to the rail resulting in a stiffer knob,
and rotating the barrel clockwise will release pressure on the rail.
