7.4.4: How to clean the lenses:
CAUTION!
ALWAYS ALLOW THE AUTO600 TO COOL BEFORE USING ANY
CLEANING SOLVENT OR FLUID ON THE OPTICS. SURFACES WILL
BE HOT IF IT HAS BEEN IN USE.
It is important to use a lens cleaning fluid that leaves no residue with an
optical quality microfiber cloth to minimise the risk of damaging the lens
surfaces. These are readily available for use with camera lenses etc.
NOTE: Always apply the cleaning fluid to the cloth not to the lens.
After cleaning leave in a warm dry place for enough time for all of the
cleanser residue to evaporate.
7.4.5: How to clean the measurement tube.
CAUTION!
THE SOOT PARTICLES RELEASED DURING CLEANING CAN
CAUSE IRRITATION IF INHALED. ALWAYS ALLOW THE AUTO600
TO COOL BEFORE PERFORMING THIS OPERATION. SURFACES
MAY BE HOT.
The measuring tube is coated with black paint and care must be taken if
cleaning this tube to ensure that this surface is not degraded by the
cleaning process.
The tube can be cleaned using a soft ‘bottle’ brush. It needs to be
pushed in and pulled out a few times and be rotated whilst doing so to
loosen any soot that has attached itself to the wall of the measurement
tube. A vacuum cleaner (not supplied) can be used to extract any
loosened particles. The use of compressed air is
NOT
recommended.
