MAINTENANCE  &  ADJUSTMENTS

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.

Tension Calibration Procedure

During power up press both ESC and 
ENTER buttons to enable the calibra-
tion mode.  

The display will show 22 lbs  or 10 kgs.  
KG/LBS can be changed at any time by 
pressing the LB/KG Button.

Using a Tension Calibrator, apply tension 
to the calibrator and adjust the value on the 
display up or down to match the reading on 

the calibrator.  Press the ENTER button to confi rm and release the tension on the calibrator.

When the Gripper returns to the home position the display will now show 44 lbs or 20 kgs. 
Apply tension to the calibrator and adjust the value on the display up or down to match the 
reading on the calibrator.  Press the ENTER button to confi rm and release the tension on 
the calibrator.

When the Gripper returns to the home position the display will now show 66 lbs or 30 kgs. 
Apply tension to the calibrator and adjust the value on the display up or down to match the 
reading on the calibrator.  Press the ENTER button to confi rm and release the tension on 
the calibrator.

When the Gripper returns to the home position the display will now show 88 lbs or 40 kgs. 
Apply tension to the calibrator and adjust the value on the display up or down to match the 
reading on the calibrator.  Press the ENTER button to confi rm and release the tension on 
the calibrator. The Calibration procedure is now complete.

NOTE: If ESC is pressed at any time during calibration, the calibration procedure will 
be terminated and no new calibration data will be saved.
