Maintenance and Service
Maintenance and Cleaning
Keep the measuring tool clean at all times.
Never immerse the measuring tool in water or other liquids.
Wipe off any dirt using a damp, soft cloth. Do not use any detergents or solvents.
The areas around the outlet aperture of the laser in particular should be cleaned on a reg-
ular basis. Make sure to check for lint when doing this.
Cleaning the Gel Pad
Clean the gel pad (14) whenever it has become contaminated with dust or other
particles, or if its adhesive strength has been reduced.
u Only wash the gel pad when it has been detached from the tool. The measuring
tool itself must not be washed or submerged in water.
To detach the gel pad, turn the gel pad holder (13) anticlockwise and take off the holder.
Rinse the gel pad (14) with water. Wash it as necessary using a common household neut-
ral soap or a detergent. Do not use any cleaning agents that contain alcohol or solvents. If
necessary, the protective cap (15) should also be cleaned.
