2. General Safety Instructions
WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
2.1 Work Area Safety
- Keep 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. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
- 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 hearing protection when operating the tool for extended periods.
- 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.
2.4 Tool Use and Care
- Do not force the power tool. Use the correct power tool for your application.
- Disconnect the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools.
- Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool.
- Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation.
2.5 Battery Tool Use and Care
- Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
- Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
- When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
- Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

- Slide the battery into the port until it locks securely into place. Ensure it is fully seated to prevent accidental dislodgement during operation.
- To remove the battery, press the release button(s) on the sides of the battery pack and slide it out.
4.3 Attaching the Auxiliary Handle
For improved control and safety, especially during high-torque applications or hammer drilling, attach the auxiliary handle.
- Loosen the auxiliary handle clamp by rotating it counter-clockwise.
- Slide the handle over the front of the drill body, positioning it to your preferred angle.
- Tighten the clamp by rotating it clockwise until the handle is securely fastened.

4.4 Installing Drill Bits or Accessories
- Ensure the drill is off and the battery is removed for safety.
- Grip the rear collar of the 1/2-inch full-metal ratcheting chuck and rotate the front collar counter-clockwise to open the chuck jaws.
- Insert the drill bit or accessory fully into the chuck jaws.
- Rotate the front collar clockwise to tighten the chuck jaws firmly around the bit. The ratcheting mechanism will provide an audible click when securely tightened.
- Gently pull on the bit to ensure it is properly secured.

5. Operating Instructions
5.1 Powering On/Off and Speed Control
- Trigger Switch: Squeeze the trigger switch to turn the drill on. Release it to turn the drill off.
- Variable Speed: The trigger switch is pressure-sensitive, allowing for variable speed control. Pressing the trigger further increases the speed.
- Forward/Reverse Selector: Located above the trigger, push the selector left for forward rotation (drilling/driving) and right for reverse rotation (removing screws). Center position locks the trigger for safety.
5.2 Gear Selection (2-Speed)
The drill features a 2-speed gearbox for optimal performance across various applications.
- Gear 1 (Low Speed, High Torque): Slide the gear selector switch to position '1'. Ideal for driving screws, drilling large holes, or applications requiring maximum torque.
- Gear 2 (High Speed, Lower Torque): Slide the gear selector switch to position '2'. Suitable for fast drilling of smaller holes in wood or metal.
NOTE: Always ensure the drill is stopped before changing gear settings to prevent damage to the gearbox.
5.3 Mode Selection (Drill, Drive, Hammer Drill)
Rotate the collar behind the chuck to select the desired operating mode:
- Drill Mode (Drill Icon): For drilling holes in wood, metal, and plastics.
- Drive Mode (Screw Icon): For driving screws. The clutch settings (numbered ring) allow you to adjust the torque to prevent over-driving screws or damaging materials.
- Hammer Drill Mode (Hammer Icon): For drilling into masonry, brick, and concrete. This mode combines rotary action with a hammering motion.
5.4 Turbo Mode
The Turbo Mode button, located on top of the drill, provides an immediate increase in speed for faster results when needed.
- Press the TURBO button during operation to engage maximum speed.
- Release the button to return to the previously selected speed setting.
Figure 5: The Turbo Mode button, when pressed, provides increased speed for rapid task completion.
5.5 Anti-Kickback Feature
The drill is equipped with an advanced anti-kickback braking technology. If the drill bit binds during operation, the system will detect the sudden rotational force and rapidly stop the motor to reduce the risk of kickback and potential injury.
5.6 Integrated LED Light
An LED light is integrated into the drill to illuminate the work area, improving visibility in dimly lit conditions. The light activates when the trigger is pressed.
Figure 6: The integrated LED light provides illumination for improved visibility in dark work environments.
5.7 Drilling into Masonry (Hammer Drill Mode)
When drilling into masonry, brick, or concrete:
- Select Hammer Drill Mode.
- Ensure the auxiliary handle is securely attached and held firmly with both hands.
- Use appropriate masonry drill bits.
- Apply steady, firm pressure to the drill, allowing the hammering action to break up the material.

6. Maintenance
6.1 Cleaning
- Always disconnect the battery pack before performing any cleaning or maintenance.
- Use a soft brush or compressed air to clean dust and debris from the ventilation openings.
- Wipe the tool housing with a damp cloth. Do not use harsh chemicals or abrasive cleaners.
- Keep the chuck jaws clean and free of debris to ensure proper bit gripping.
6.2 Storage
- Store the tool, batteries, and charger in a cool, dry place, away from direct sunlight and moisture.
- Ensure batteries are partially charged (not fully depleted or fully charged for long-term storage) before storing.
- Store the tool in its carrying case to protect it from damage.
