5. Setup

5.1. Charging the Battery

The battery pack is not fully charged at the time of purchase. It must be fully charged before first use.

1. Connect the charger to a standard power outlet.
2. Slide the battery pack onto the charger base. Ensure it clicks into place.
3. The charging indicator light on the charger will show the charging status. A full charge takes approximately 45 minutes for a 1.5 Ah battery.
4. Once fully charged, disconnect the battery from the charger and unplug the charger from the outlet.

5.3. Installing and Removing Drill Bits/Driver Bits

1. Rotate the keyless chuck counter-clockwise to open the jaws.
2. Insert the drill bit or driver bit into the chuck, ensuring it is centered.
3. Rotate the keyless chuck clockwise to tighten the jaws firmly around the bit. Do not overtighten.
4. To remove, rotate the chuck counter-clockwise until the bit can be pulled out.

6. Operating Instructions

6.1. Selecting Speed

The drill driver features two mechanical speed settings:

• Speed 1 (Low Speed, 0-350 RPM): Ideal for driving screws, larger drilling diameters, or applications requiring higher torque.
• Speed 2 (High Speed, 0-1350 RPM): Suitable for smaller drilling diameters and faster drilling.

To change speed, slide the speed selector switch located on top of the drill. Ensure the tool is stopped before changing speeds.

6.2. Adjusting Torque

The torque adjustment collar has 18 torque settings plus a drill mode (indicated by a drill bit symbol).

• Torque Settings (1-18): Use these settings for driving screws. Lower numbers are for smaller screws or softer materials, higher numbers for larger screws or harder materials. The clutch will disengage when the set torque is reached, preventing overtightening or stripping.
• Drill Mode (Drill Bit Symbol): Provides maximum torque for drilling applications without the clutch disengaging.

Rotate the torque adjustment collar to select the desired setting.

6.3. Forward/Reverse Rotation

The forward/reverse switch is located above the trigger. Push it to the left for forward rotation (for drilling and driving screws) and to the right for reverse rotation (for removing screws or freeing jammed bits). Position the switch in the center to lock the trigger and prevent accidental starting.

6.4. Operating the Trigger Switch and LED Light

Squeeze the trigger switch to start the drill. The speed is variable depending on how far the trigger is pressed. The integrated LED work light will illuminate when the trigger is pressed, providing visibility in dimly lit areas.

7. Maintenance

Regular maintenance ensures optimal performance and extends the life of your tool.

• Cleaning: Keep the ventilation openings clear and free of dust. Use a soft, damp cloth to clean the tool casing. Do not use solvents or abrasive cleaners.
• Battery Care: Store batteries in a cool, dry place away from direct sunlight. Do not store fully discharged batteries for extended periods. Charge them periodically if not in use.
• Storage: Store the drill driver, batteries, and charger in the provided carrying case in a dry, secure location out of reach of children.
• Inspection: Regularly inspect the power tool for any signs of damage, loose screws, or worn parts. If damage is found, have it repaired by a qualified service technician.
