8 Care and maintenance
8.1 Cleaning and drying
1. Blow dust off the lenses.
2. Do not touch the glass with the fingers.
3. Use only a clean, soft cloth for cleaning. If necessary,
moisten the cloth slightly with pure alcohol or a little
water.
NOTE
Do not use any other liquids as these may
damage the plastic components.
4. Observe the temperature limits when storing your
equipment. This is particularly important in winter
/ summer if the equipment is kept inside a motor
vehicle (-20°C to +60°C / -4°F to 140°F).
8.2 Storage
Remove the tool from its case if it has become wet.
The tool, its carrying case and accessories should be
cleaned and dried (at m60°C / 140°F). Repack
the equipment only once it has dried completely and then
store it in a dry place.
Check the equipment before it is used after a long period
of storage or transportation.
8.3 Transport
Use the Hilti packaging or packaging of equivalent quality
for transporting or shipping your equipment.
