Safety instructions
This height measuring instrument complies with the relevant safety regulations.
It was dispatched from our production facility in a perfect condition. However,
failure to follow the instructions given below can cause personal injury or death:
1. Before you connect up and use the measuring instrument for the first time,
please read the accompanying documentation.
2. Only use the instrument in accordance with this quick guide.
Keep the documentation close to the place of use ready for quick reference.
3. This instrument is not designed for operation in explosive environments.
An electrical spark could trigger an explosion.
4. Follow safety precautions, accident prevention regulations, and internal
company guidelines. You should request further information from your
company safety officer.
5. Only the AC adapter provided with the device should be used for charging
the internal rechargeable battery or supplying power to the device when
used in stationary applications.
6. Before you connect up the equipment, check that the power supply voltage
marked on the type plate of the AC adapter matches that of the local mains
power supply system. Do not under any circumstances connect the AC
adapter if the voltage is not the same!
7. Only use the AC adapter in enclosed areas.
8. The instrument may only be connected to a properly grounded protective
contact socket. Any extension cables must meet the stipulations of the VDE
(German Association for Electrical, Electronic & Information Technologies).
9. Only Mahr-trained service personnel are permitted to carry out work on this
instrument. Protective covers must only be removed by trained technicians

10. Do not use cleaning agents that contain harmful substances. Do not use
solvents. Do not allow any fluids to penetrate the instrument.
11. Inspect the connecting cables for damage. Change damaged cables
immediately (Mahr service personnel).
12. Never move the height measuring instrument forcefully at the edge of the
measuring plate. The air cushion at the edge does not dissipate quickly

Itcould fall off the plate and injure the user.
13. The height measuring instrument must only be transported in its original
packaging. Otherwise the warranty will be void.
