Tension Calibration Procedure - Step 1
Set the tension to 60 lbs. as indicated by the
linear scale and rotary knob. Place the string
on one end of a tension calibrator into a string
clamp and secure. Place string located on
the other end of the calibrator into the string
tensioner and apply tension. If the brake
lever releases before 60 lbs. or after 60 lbs.,
the tension head should be calibrated as
follows.
Tension Calibration Procedure - Step 2
Loosen the plastic locking screw located on
the side of the latching block as shown. The
plastic screw is used to hold the adjustment
screw in place.
Tension Calibration Procedure - Step 3
If the lever releases before 60 lbs., turn the
adjustment screw located on the left side of
the latch block counter-clockwise to increase
the engagement of the brake release latch
with the brake lever. Repeat step 1 and
adjust until the correct tension is indicated on
the calibrator.
If the tension indicated in step 1 is greater
than 60 lbs., turn the adjustment screw clock-
wise to reduce the engagement of the brake
release latch with the brake lever. Repeat
step 1 and adjust until the correct tension is
indicated on the calibrator.
