2. General Safety Instructions
Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury. Keep this manual for future reference.
2.1. Work Area Safety
- Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
- Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.
- Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2.2. Electrical Safety
- Power tool plugs must match the outlet. Never modify the plug in any way.
- Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
2.3. Personal Safety
- Always wear eye protection. Use safety glasses, goggles, or a face shield.
- Wear appropriate personal protective equipment (PPE) such as hearing protection, dust mask, and non-skid safety shoes.
- Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.
- Stay alert, watch what you are doing, and use common sense when operating a power tool.

4.4. Installing/Removing Drill Bits or Screwdriver Bits
- Ensure the tool is switched off and the forward/reverse switch is in the center (locked) position to prevent accidental starting.
- Rotate the chuck collar counter-clockwise to open the chuck jaws.
- Insert the drill bit or screwdriver bit fully into the chuck.
- Rotate the chuck collar clockwise to tighten the jaws firmly around the bit. Ensure the bit is centered and secure.
- To remove, rotate the chuck collar counter-clockwise to loosen the jaws and pull the bit out.
5. Operating Instructions
5.1. Powering On/Off and Variable Speed Control
- To Power On: Press the trigger switch. The integrated LED light will illuminate the work area.
- To Power Off: Release the trigger switch.
- Variable Speed: The tool's speed is controlled by the amount of pressure applied to the trigger switch. Pressing lightly results in lower speed, while pressing fully increases the speed.
5.2. Forward/Reverse Rotation
The forward/reverse switch (selector) is located above the trigger. It controls the direction of rotation and also acts as a lock-off mechanism.
- Forward Rotation: Push the switch to the left (when viewed from the rear of the tool).
- Reverse Rotation: Push the switch to the right.
- Lock-Off: When the switch is in the center position, the trigger is locked, preventing accidental starting. Always engage the lock-off when changing bits or not in use.
5.3. Torque Adjustment and Mode Selection
The torque adjustment ring allows you to select the desired torque setting for screwdriving or switch between drilling modes.
- Screwdriving (1-20): Rotate the ring to select a torque setting from 1 to 20. Lower numbers are for smaller screws or softer materials, higher numbers for larger screws or harder materials.
- Drilling Mode (Drill Symbol): Select this mode for general drilling in wood or metal without impact.
- Impact Drilling Mode (Hammer Symbol): Select this mode for drilling in masonry or concrete, utilizing the impact mechanism.
5.4. Speed Gear Selector
The gear selector switch, located on top of the drill, allows you to choose between two speed ranges.
- Gear 1 (Low Speed, High Torque): 0-500 RPM. Ideal for heavy-duty screwdriving, drilling large holes, or applications requiring maximum torque.
- Gear 2 (High Speed, Low Torque): 0-2000 RPM. Suitable for fast drilling of smaller holes and lighter screwdriving tasks.
Always ensure the tool is stopped before changing gears to prevent damage to the gearbox.
