MAINTENANCE and ADJUSTMENTS

High LBs

High KGs

Rotate screw ("Low LBs") in small increments until the displayed tension matches the

tension indicated on the calibrator. Set the machine tension to 60 lbs. and apply tension to

the calibrator. If the measured tension is innacurate, rotate screw ("High LBs") in small

increments until the displayed tension matches the tension indicated on the calibrator. Since

adjustment of the "Low LBs" screw at 20 lbs can influence the tension at 60 lbs and visa

versa, repeat these steps until the set tension matchs the tension reading of the calibrator

at both 20 and 60 lbs. Replace the rectangular cover in the L.E.D. display cover plate.

To switch from Lbs to Kgs, slide the units selection switch to the left for "LBs" and to the right

for "KGs".

Please note that there will be a range of tension from the maximum tension at which the

tensioner stops pulling (high end of the range), to the minimum tension at which the tensioner

starts pulling again (low end of the range). This difference between the high and low end of

the range can vary from 2-4 lbs depending on the string used to calibrate the machine and

the speed of the tensioner. For consistency, we recommend that the tension setting of the

machine be calibrated as close as possible to the high end of the range, which is the method

used at the factory. Using this method will be the most consistent and will also insure that

the racquet will not be over tensioned.

Tension Calibration Procedure

If you suspect that tensioner is not pulling the

correct tension, you should check the tension

with a Tension Calibrator which provides a mea-

surement of the actual pulling tension being

applied by the machine.

With the tension set at 20 lbs, place one end of

a calibrator equipped with synthetic string into a

string clamp. Place the opposite end into the

string gripper and apply tension. If the measured

tension is inaccurate, remove the rectangular

cover from the L.E.D. display cover plate cover.
