Technical Data; Gears And Corresponding Core Bit Diameters - Hilti DD 120 Manual De Instrucciones

Switching other power tools, machines or appliances on and off can cause undervoltage and/or
overvoltage peaks, resulting in damage to the machine.

4.3 Noise information and vibration values in accordance with EN 62841
The sound pressure and vibration values given in these instructions were measured in accordance with a
standardized test and can be used to compare one power tool with another. They can also be used for a
preliminary assessment of exposure.
The data given represent the main applications of the power tool. However, if the power tool is used for
different applications, with different accessory tools, or is poorly maintained, the data can vary. This can
significantly increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times when the tool is switched off, or
when it is running but not actually being used for a job. This can significantly reduce exposure over the total
working period.
Identify additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: maintaining the power tool and accessory tools, keeping the hands warm, organization of work
patterns.
