TROUBLESHOOTING TIPS
CARE & CLEANING
With time and use, the clamping surfaces of your machine may become oily or dirty and
result in string or clamp slippage while stringing. Periodic cleaning of the String Clamps,
String Clamp Base and String Gripper is recommended. Knife sharpening stones work well
for cleaning the diamond coated string clamping surfaces. Cleaning with a solvent such as
isopropyl alcohol and a mild abrasive tool such as a toothbrush also works well to remove
oily or greasy build up.
PROBLEM SOLUTION
String slips in clamps - Adjust gap between clamp jaws
- Clean clamp jaws
String slips in gripper - Clean gripper jaws
- Adjust gripper jaw stop screw
String clamp base slips on turntable - Clean bottom of clamp & top of turntable with
alcohol
- Adjust clamp base locking nut
String tension too tight or too loose - Check tension using a tension calibrator,
adjust machine calibration if necessary
2pt Hold Down Clamp Adjustment
The 2pt hold down clamps have been adjusted at
the factory. However, depending on the racquet
frame thickness, the hold down clamp may require
adjustment. Use a 3 mm hex wrench and turn the
set screw clockwise to reduce the hold down clamp
pressure and counter clockwise to increase the hold
down clamp pressure.
Note: To avoid potential damage to the racquet
only make small adjustments at a time by slightly
turning the set screw by no more than 1/4 of a turn.
Test the hold down lever to insure the racquet is
held snuggly but without applying excessive force
to the lever.
Periodically clean the hold down clamp pin using rubbing alcohol to remove residue or dirt,
that may build up over time.
