5.2 Cleaning the Optical Parts
Trotec recommends to use following cleaning material:
Lens tissues Part number 69249
Lens cleaner Part number 69248
The lens has a durable multi-coating and won’t be damaged by correct and careful cleaning.
You should inspect the mirrors and the lens according the maintenance plan. If you discover
a veil of haze or dirt, you must clean them.
Follow the instructions below for the cleaning of optical parts:
5.2.1 CLEANING THE LENS
1. Move the engraving table to a distance approx. 10 cm under the lens holder.
2. Move the working head into the center of the working surface and put a cloth under the
lens holder (so that the lens is not damaged if it accidentally falls out of its holder).
3. Now you can unscrew the lens holder (1).
4. Once positioned over a clean lens cleaning tissue, remove the lens from the lens holder
by carefully turning the lens holder and letting the lens and the O-ring drop onto the
cleaning cloth.
5. Examine the O-ring and, if necessary, clean it with a cotton bud and a lens cleaning
tissue.
6. Remove the coarse dust as good as possible by blowing air onto the lens surface.
7. Check the surface and if necessary clean the lens with the lens cleaning liquid and lens
tissue.
