2. Safety Instructions

Always follow basic safety precautions to reduce the risk of fire, electric shock, and personal injury.

• Work Area Safety: Keep your 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.
• Electrical Safety: Avoid body contact with earthed or grounded surfaces. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
• Personal Safety: Always wear eye protection. Use hearing protection when operating for extended periods. Dress properly; avoid loose clothing or jewelry. Keep hair, clothing, and gloves away from moving parts.
• 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.
• Battery Pack Use and Care: Recharge only with the charger specified by the manufacturer. Do not use battery packs with any other power tools. When the battery pack is not in use, keep it away from other metal objects.

5.2 Battery Installation and Removal

• Installation: Align the battery pack with the base of the drill handle and slide it in until it clicks securely into place.
• Removal: Press the battery release buttons on the sides of the battery pack and slide the battery out of the drill.

5.3 Accessory Installation and Removal (Drill Bits, Screwdriver Bits)

The drill features a 10mm (3/8") keyless chuck for quick and easy bit changes.

1. To Open the Chuck: Rotate the chuck collar counter-clockwise until the jaws are wide enough to insert the desired bit.
2. To Insert a Bit: Insert the shank of the drill bit or screwdriver bit into the chuck jaws. Ensure the bit is centered.
3. To Close the Chuck: Rotate the chuck collar clockwise until the bit is firmly secured. Do not overtighten.
4. To Remove a Bit: Rotate the chuck collar counter-clockwise to loosen the jaws and pull the bit out.

6. Operating Instructions

6.1 Power On/Off and Variable Speed Trigger

The drill is activated by pressing the variable speed trigger. The speed of rotation is controlled by the amount of pressure applied to the trigger. Pressing lightly results in lower speed, while pressing fully results in maximum speed.

6.2 Speed Selection

The drill has two speed settings, selected via the speed selector switch located on top of the drill.

• Speed 1 (0-500 RPM): For screwdriving applications and drilling larger holes in softer materials. Provides higher torque.
• Speed 2 (0-1850 RPM): For drilling smaller holes and general drilling in various materials. Provides higher speed.

6.3 Torque Adjustment

The torque adjustment ring allows you to select from 25 torque settings plus a drill mode. This prevents overtightening screws and damaging materials.

• Settings 1-25: For screwdriving. Start with a lower setting and increase as needed until the screw is driven flush without stripping.
• Drill Mode (Drill Icon): For drilling applications. This setting provides maximum torque for drilling.

6.4 Forward/Reverse Rotation

The forward/reverse switch, located above the trigger, controls the direction of rotation.

• Pushing the switch to the left (when viewed from the rear) sets the drill to forward rotation for driving screws or drilling.
• Pushing the switch to the right sets the drill to reverse rotation for removing screws or backing out drill bits.
• When the switch is in the center position, the trigger is locked, preventing accidental startup.

6.5 LED Work Light

The integrated LED light automatically illuminates the work area when the trigger is pressed, improving visibility in dimly lit spaces.

6.6 Drilling and Screwdriving Techniques

• Drilling: Select the appropriate drill bit and speed. Apply steady, even pressure. For hard materials, use a slower speed and apply cutting fluid if necessary.
• Screwdriving: Select the correct screwdriver bit and torque setting. Hold the drill firmly and apply pressure in line with the screw to prevent cam-out.

• Cleaning: Keep the ventilation slots clear and free of dust. Use a soft, damp cloth to clean the tool casing. Do not use harsh chemicals or abrasive cleaners.
• Chuck Maintenance: Periodically clean the chuck jaws to ensure proper gripping of bits.
• Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store fully discharged batteries for extended periods.
