Assembly and Operation

Power Supply

Remove the cover for the Bluetooth® Low Energy Module GCY 42 on the power tool, e.g. using a screwdriver or a large coin. Using unsuitable objects can damage the electronics or the cover.
- To start using the product after purchasing it or to change the battery (1), follow the illustrations on the graphics pages. Observe the following advice when doing so.

Initial Starting Operation
(see figures A1–A5)

Note: Store the placeholder (3) of the GCY 42 in a safe place. Refit the placeholder when passing the power tool on without the GCY 42.

Place the battery (1) in the GCY 42 (2) with the plus terminal facing upwards. You do not need to push the battery in as the battery does not engage. It is simply secured in the correct position when you close the cover.

To initialise the GCY 42 after inserting the battery, press the on/off switch of the power tool.

Changing the Battery (see figures B1–B4)

Only remove the used battery (1) with your fingers.
A warning will be displayed in the app before the battery is fully used up.

Removing the GCY 42 (see figures C1–C2)

Do not use force to remove the GCY 42 (2). Do not use any sharp or pointed tools.
Note: Turning the power tool over may make it easier to remove the GCY 42.

Starting operation
Once you have inserted the battery (1) and pressed the on/ off switch on the power tool, the GCY 42 will transmit a signal continuously. The Bluetooth® signal will only stop the battery is drained or faulty, or if the battery is removed.
