Adjust the Base of the Swivel Clamp to the correct holding
pressure
If the Clamp base is no longer working very well, put the clamp base vertical to
the track. Insert the 3mm Allen wrench into the hole on the side of the base,
before you have to remove the black cap. Then turn it clockwise only slightly,
do not use excessive force, this could damage the base. It can be very difficult
do turn. Then put the Allen wrench out of the base and test if it is working well
again, if not repeat the process again. So you do not have to adjust on the base of
the clamp base. Only at this screw!
