Starting Operation

To start the power tool, first press the lock-off switch (2), then press and hold the on/off switch (1).

To switch off the power tool, release the on/off switch (1).

Note: For safety reasons, the on/off switch (1) cannot be locked; it must remain pressed during the entire operation.

To open the water supply, put the valve (16) into position I: Water will flow continuously over the diamond cutting disc.

To close the water supply, put the valve (16) into the OFF position.

The worklight (19) will light up when the on/off switch (1) is fully pressed. The worklight will remain lit for approx. 5 seconds after the on/off switch (1) has been released.

The power tool is equipped with an overload protection system. In the event of overloading, the power tool automatically shuts off the electronics and the worklight (19) and the status indicator (21) flash.
To switch the tool back on: Release the on/off switch (1). As soon as the worklight (19) is no longer flashing and the status indicator (21) lights up green, you can switch the power tool back on.
