7. Remove the four screws (8) securing the left collimator cover (small Pozi screwdriver).
8. Clean the left collimator cover with the small static duster, and ensure that it is free from dust.
9. Inspect the mirror, and if it contains dust use a cotton bud or similar (e.g. a digital camera sensor
cleaner) to clean it. If necessary, add some ethanol to the cotton bud to assist the removal of the
dust. The use of ethanol may require that you clean the mirror a number of times, so that there is no
smearing.

Never touch the mirror with your fingers as the natural oils in your finger can damage the mirror.
