Congratulations on the purchase of laser distance meter HITACHI HDM 40!
Permitted use
· Measuring distances
· Computing functions, e.g. areas, volumes, subtractions, Pythagorean calculation
Thesafetyregulationsandinstructionsalongwiththeoperatingmanualshouldbereadcarefullybeforeinitialoperation.
The person responsible for the instrument must ensure that equipment is used in accordance with the instructions. This
person is also accountable for the deployment of personnel and for their training and for the safety of the equipment
