Gripper Plate Spacing Adjustment
The Gripper Plates of the String Gripper are ad-
justable to accommodate various string gauges
and types of string. If the string slips through the
Gripper Plates while pulling tension, insert a 2.5mm
hex wrench through the access hole on the back
of the right Gripper Plate and into the Adjustment
Screw. Turn the Adjustment Screw clockwise to
increase the compression on the string. If too
much pressure is applied to the string while pull-
ing tension, rotate the Gripper Adjustment Screw
counter-clockwise to reduce the compression on
the string. The Gripper Plates are properly adjusted
when there is enough pressure to securely hold
the string without slipping and without excessively
compressing the string.
TIP: If you turn off the machine with the Gripper located at the far right side of the track,
it is easier to access the Adjustment Screw.
