Safety Instructions
This height measuring instrument employs the state-of-the-art technology and complies with recognized safety
regulations.
Nevertheless, the operator or third parties can risk life or limb if the following safety instructions are not strictly
observed!
1. All operators must read the safety instructions and the enclosed operating instructions thoroughly before
putting the height measuring instrument into operation.
2. This height measuring instrument must only be used if it is in perfect technical condition. Any malfunctions,
particularly those impairing safety, must be eliminated immediately.
3. This height measuring instrument must only be used for the intended purposes and in accordance with the
operating instructions provided. The operating instructions must be stored in the immediate proximity of the site
where the height measuring instrument is being used.
4. Before connecting the height measuring instrument to the mains, make sure that the voltage specified on the
rating plate agrees with the local mains voltage. If the two voltages do not agree, do not connect the height
measuring instrument under any circumstances!
5. The height measuring instrument may only be connected to socket outlets with properly grounded contacts.
Extension cables must meet the stipulations of the local electrical standards or similar.
6. Any modification or manipulation of the height measuring instrument requires the express written approval of
Mahr GmbH and must be carried out by qualified personnel. Unauthorized opening of the height measuring
instrument and unauthorized intervention invalidates the warranty and frees Mahr GmbH from any liability.
Before opening the height measuring instrument, switch off the unit and pull the mains plug from the mains
socket outlet.
7. Before cleaning the height measuring instrument, pull the mains plug from the mains socket outlet. Never let
any liquids penetrate the height measuring instrument! Do not use cleaning agents that are harmful to plastics.
8. If a fuse needs replacing, only a fuse of the same type - in terms of Amperage and blow characteristics - may
be used. When exchanging fuses, follow the procedure outlined in the operating instructions.
9. All relevant safety and accident prevention regulations must be complied with.Your safety expert will provide
further instructions based on local circumstances and in-house guidelines.
10. Do not operate the height measuring instrument in rooms filled with explosive gases. An electrical spark could
trigger an explosion.
11. Never move the height measuring instrument to the edge of the base plate at speed. The air cushion carrying
the column will be unable to dissipate quickly enough to decelerate the height measuring instrument before it
reaches the edge. This could cause the height measuring instrument to fall off the base plate and harm the
operator.
When returning the height measuring instrument, please ONLY ship the height measuring
instrument in its original carrying case and on an appropriate pallet!
Failure to do this will invalidate the warranty!
