GAMMA PROGRESSION STII STRINGING MACHINE (Issue 5 - January 2009) - Manual (Page 15)

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 coatied string clamping surfaces. Cleaning with a solvent such as
isoproyl alcohol and a mild abrasive tool such as a toothbrush also works well to remove oily
or greasey build up.
