# Practical Advice

- With the Bluetooth® Low Energy Module GCY 42, the power tool is equipped with a radio interface. Local operating restrictions, e.g. in aircraft or hospitals, must be observed.

- In areas in which the Bluetooth® wireless technology must not be used, the Bluetooth® Low Energy Module GCY 42 and the coin cell must be removed.

Note: The cover (13) can only be closed securely if the Bluetooth® Low Energy Module GCY 42 and the coin cell are in the power tool.

- To deactivate the Bluetooth® Low Energy Module GCY 42, turn the coin cell over or place a means of insulation between the coin cell and Bluetooth® Low Energy Module GCY 42.
- Close the cover (13) to prevent dirt from getting in.

You can use the depth stop (17) to set the required drilling depth X.

- Press the button for depth stop adjustment (15) and insert the depth stop into the auxiliary handle (16).
  The fluting on the depth stop (17) must face downwards.
- Push the SDS plus application tool into the SDS plus tool holder (3) as far as it will go. Otherwise, the movability of the SDS plus drilling tool can lead to incorrect adjustment of the drilling depth.
- Pull the depth stop far enough out that the distance between the drill bit tip and the edge of the depth stop corresponds to the required drilling depth X.

##

- If the application tool jams or snags, the power transmission to the drill spindle will be interrupted. Always hold the power tool firmly with both hands to withstand the forces this may create and adopt a position with stable footing.

- Switch the power tool off immediately and remove the application tool if the power tool becomes blocked. Switching on when the drilling tool is blocked may cause high torque reactions.

##

The rapid shut-off function (KickBack Control) gives the user greater control over the power tool and offers them better protection than power tools that do not have KickBack Control. If the power tool suddenly and unforeseeably rotates around the drilling axis, it will switch off, the rapid shut-off indicator (24) will light up red and the worklight (14) will flash. When rapid shut-off is activated, the status indicator (27) flashes red.

- To switch the tool back on, release the on/off switch (11) and then press it again.

##

EPC assists you when drilling and when working with impact in sensitive materials by ensuring slow start-up of the operating speed for precise working.

##

For better control and precise positioning, the power tool starts at a low speed and then increases to the set speed.
Adapted Speed Control is started up automatically when the power tool is switched on.

##

The integrated vibration damping function reduces the generated vibration.

- Do not continue to use the power tool if the damping element is damaged.
