Hilti DCH 300 Mode D'emploi Original page 30

3.7 Electronic overload protection
The cutter is equipped with an electronic overload protection system that monitors current input.
If the current drawn by the motor is too high, e.g. due to application of excessive pressure by the user, the
electronic overload protection system switches the power tool off.
To switch the power tool on again, release the on/off switch and then press it again.
The user should aim to work continuously with the tool without activation of the automatic cut-out.
The user can prevent activation of this automatic cut-out by reducing the pressure applied to the tool.

Status
