CLEANING
NEEDLES
Periodically clean the electrode needles. Failure to clean the needles will inhibit the
static removal performance, and can lead to failures such as burning.
Cleaning the electrode needles
The electrode needles must be cleaned once a month to ensure the optimum static removing
performance.
The cleaning cycle may differ according to the eraser's installation environment.
Be careful when cleaning the electrode needle as the tip is very sharp. "
