Leica L2 User manual
• Put a dust cover over the instrument during pauses in
work.
• Remove dust with a rubber blower or soft brush.
• Clean objectives and eyepieces with special optic
cleaning cloths and pure alcohol.
• Protect accessories against dust when not in use.
The use of unsuitable cleaning agents and techniques can
damage polymers, so always observe the following rules:
• Never clean polymers in an ultrasonic bath.
They can become brittle and later break.
• Never use corrosive cleaning agents or agents
containing acetone, e.g. ether substitute.
• Never use solvents (except for ethanol or
isopropanol).
• Wipe down the outside of the instrument with a soft
dry cloth or with off-the-shelf cleaning cloths for
polymers.
• The best method is generally to use warm soapy wa-
ter and rinse afterwards with distilled water because
the soapy water does not attack the polymer and is
environmentally acceptable.
• Clean with industrial alcohol or isopropanol, taking
appropriate safety precautions.
Always take appropriate safety precautions when using
industrial alcohol and isopropanol.
