• Apply pressure in a straight line with the bit and do not apply excessive pressure.

Operating Instructions

Assembly:

1. Mounting the Auxiliary Handle (Fig. A): Rotate the handle counter-clockwise to loosen the clamping ring. Slide the clamping ring over the drill's handle sleeve and rotate the handle to the desired working position. Tighten the handle clockwise. The auxiliary handle must be used during operation.
2. Mounting the Depth Gauge (Fig. B): Loosen the locking screw (a) on the auxiliary handle. Insert the depth gauge into the handle sleeve. Adjust to the desired drilling depth. Tighten the locking screw.
3. Inserting and Removing the Bit (Fig. C): Clean and lightly lubricate the bit before insertion. Insert the bit into the tool holder with a twisting motion until it locks. Check the lock by pulling the tool. To remove, pull back the tool holder sleeve and pull out the bit. Use only high-quality SDS bits.

Operation:

1. Trigger Switch (Fig. D): Press the trigger switch to start. The speed is variable and controlled by the pressure applied to the switch.
2. Lock-on Button (Fig. E): To lock the tool on, press the trigger switch, then the lock-on button, and release the trigger switch. To turn off, simply press and release the trigger switch.
3. Changing Rotation Direction (Fig. F1, F2): With the tool facing away from you, press the forward/reverse lever. To reverse, press the lever again. Never change the direction of rotation while the tool is running.
4. Mode Selection (Fig. G): Press the release button (b) and rotate the mode selection dial to choose the desired function: drilling with hammering (concrete/brick), drilling (steel/wood/plastic), or chiseling. Ensure the dial is locked in place.
