3. Setup

3.1 Unpacking

• Carefully remove the drill and all accessories from the packaging.
• Inspect the tool for any damage that may have occurred during transit. Do not operate a damaged tool.
• Ensure all components listed in the packaging are present.

3.2 Attaching the Auxiliary Handle

The auxiliary handle provides additional control and stability during operation. Loosen the handle by twisting it counter-clockwise, slide it onto the drill's neck, and then tighten it by twisting clockwise at the desired position.

3.3 Inserting Drill Bits (Keyless Chuck)

1. Ensure the drill is disconnected from the power supply.
2. Rotate the front part of the chuck counter-clockwise until the jaws are open wide enough to insert the drill bit.
3. Insert the drill bit fully into the chuck.
4. Rotate the front part of the chuck clockwise to tighten the jaws securely around the drill bit. Ensure the bit is centered and firmly gripped.

3.4 Power Connection

Connect the drill's power cord to a suitable 220-230V AC power outlet. Ensure the power outlet is properly grounded and protected by a residual current device (RCD) if working in damp conditions.

4. Operating Instructions

4.1 Powering On/Off and Variable Speed Control

• To start the drill, press the trigger switch. The drilling speed is variable and controlled by the pressure applied to the trigger.
• To stop the drill, release the trigger switch.

4.2 Lock-on Switch

For continuous operation, press the trigger switch and then press the lock-on button. The drill will continue to run without holding the trigger. To release the lock-on, press the trigger switch again.

4.3 Reversible Function

The direction of rotation can be changed using the forward/reverse selector switch, usually located above the trigger. Push the switch to the left for forward rotation (drilling) and to the right for reverse rotation (removing bits or screws). Always ensure the drill has come to a complete stop before changing the direction of rotation.

4.4 Drilling Techniques

• General Drilling: Apply steady, even pressure. Do not force the drill. Let the tool do the work.
• Wood Drilling: Use wood-specific drill bits. Start with a slower speed and increase as needed. Maximum capacity: 20 mm.
• Steel Drilling: Use HSS (High-Speed Steel) drill bits. Use a slower speed and apply cutting fluid to prevent overheating. Maximum capacity: 13 mm.
• Concrete Drilling (Impact Mode): Use masonry drill bits. Engage the impact function (if applicable, this model is an impact drill). Apply firm, steady pressure. Maximum capacity: 13 mm.
• Starting a Hole: Use a center punch for metal or a pilot hole for wood to prevent the drill bit from wandering.

5. Maintenance

5.1 Cleaning

• Always disconnect the drill from the power supply before cleaning.
• Clean the ventilation openings regularly to prevent overheating. Use a soft brush or compressed air.
• Wipe the tool housing with a damp cloth. Do not use harsh chemicals or abrasive cleaners.

5.2 Power Cord Inspection

Regularly inspect the power cord for any signs of damage, cuts, or fraying. If the cord is damaged, have it replaced by a qualified service technician to avoid electrical hazards.

5.3 Storage

Store the drill in a dry, secure place, out of reach of children. Protect it from dust and moisture. If possible, store it in its original case or a suitable storage box.
