Cleaning the cutting head lens
The cutting head lens coating is fragile; do not drop the lens onto any hard surface or touch
the lens with any sharp objects as this may damage the lens and reduce cutting efficiency.
Always use cloths that are moistened with IPA optical cleaning solution; never use dry
materials.
1.
Remove the cutting head by releasing the M3 cap head screw and detaching the air
irrigation tube.
2.
Place the cutting head onto a clean surface and unscrew the black focusing screw from
the lens barrel.
