The battery pack is not fully charged upon purchase. It is recommended to fully charge the battery before first use.

1. Connect the charger to a suitable power outlet.
2. Slide the battery pack onto the charger until it clicks into place.
3. The charging indicator on the charger will show the charging status. A full charge typically takes 30 minutes for a 2.5Ah battery.
4. Once fully charged, remove the battery from the charger.

5.2. Installing/Removing the Battery

1. To install: Align the battery pack with the base of the drill handle and slide it in until it locks securely.
2. To remove: Press the battery release button (located on the battery pack) and slide the battery pack out.

5.3. Installing Drill Bits or Screwdriver Bits

1. Ensure the drill is switched off and the battery is removed for safety.
2. Rotate the chuck counter-clockwise to open the jaws.
3. Insert the desired drill bit or screwdriver bit into the chuck.
4. Rotate the chuck clockwise to tighten the jaws securely around the bit. Ensure the bit is centered and firmly held.

6. Operating Instructions

6.1. Selecting Operating Mode (Drilling/Screwdriving/Impact)

The DEXTER impact drill features multiple modes for various applications. The torque collar allows you to select the appropriate mode:

1. Screwdriving Mode: Rotate the torque collar to the desired torque setting (1-21). Lower numbers are for smaller screws or softer materials, higher numbers for larger screws or harder materials. The clutch will disengage once the set torque is reached, preventing overtightening.
2. Drilling Mode: Rotate the torque collar to the drill symbol. This mode provides maximum torque without clutch disengagement, suitable for drilling into wood or metal.
3. Impact Drilling Mode: Rotate the torque collar to the hammer symbol. This mode activates the impact mechanism, providing additional force for drilling into masonry or other hard materials.

6.2. Speed Selection

Use the speed selector switch (typically located on top of the drill housing) to choose between two speed ranges:

• Low Speed (Gear 1): 0-450 rpm. Ideal for high torque applications like screwdriving or drilling large diameter holes.
• High Speed (Gear 2): 0-1700 rpm. Suitable for faster drilling in softer materials or smaller diameter holes.

6.3. Forward/Reverse Rotation

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

• Push left for forward rotation (for drilling and tightening screws).
• Push right for reverse rotation (for removing screws or freeing jammed bits).
• Center position locks the trigger for safety during storage or bit changes.

6.4. Operating the Drill

1. Hold the drill firmly with both hands if possible, especially during impact drilling or high torque applications. The ergonomic handle provides comfort and control.
2. Position the bit on the workpiece.
3. Gently press the trigger to start the drill. The integrated LED light will illuminate the work area.
4. Increase pressure on the trigger for higher speed.
5. Maintain steady pressure and allow the tool to do the work. Avoid excessive force.

7. Maintenance

7.1. Cleaning

• Regularly clean the ventilation slots of the tool 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.
• Keep the chuck jaws clean and free of debris for optimal bit gripping.

7.2. Battery Care
