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 following parts is recom-
mended.
String Clamps
Clean the inside gripping surfaces of the string clamp jaws by inserting a cloth or pipe cleaner
soaked with isopropyl alcohol between the jaws and rub back and forth. If the build-up is
excessive, dismantle the string clamp jaws to expose the gripping surfaces by removing the
adjustment screw. Using a small nylon brush, (such as a toothbrush), scrub the inside surfaces
until all debris is removed. Clean the jaws with isopropyl alcohol and re-assemble.
String Clamp Base
Clean the base of the clamps and the top of the turntable with isopropyl alcohol.
String Gripper
Clean inner gripping surfaces with isopropyl acohol soaked cloth or pipe cleaner.
