- Allow the battery to charge fully before first use. The charging indicator on the charger will show the charging status.
5.2. Battery Installation and Removal

- Removal: Press the battery release buttons (if present) on the sides of the battery pack and slide the battery out.
5.3. Accessory Installation
- Ensure the drill is off and the forward/reverse switch is in the center (locked) position.
- Rotate the chuck counter-clockwise to open the jaws.
- Insert the desired drill bit, screwdriver bit, or socket adapter into the chuck.
- Rotate the chuck clockwise to tighten the jaws securely around the accessory. Ensure the accessory is centered and firmly gripped.
6. Operation
6.1. Power On/Off (Variable Speed Trigger)
To start the drill, press the variable speed trigger. The speed of rotation is controlled by the amount of pressure applied to the trigger. Release the trigger to stop the drill.
6.2. Forward/Reverse Switch
The forward/reverse switch (position 9 in Figure 4.1) controls the direction of rotation and acts as a lock-off button.
- Forward (Tighten): Push the switch to the right for clockwise rotation (for driving screws).
- Reverse (Loosen): Push the switch to the left for counter-clockwise rotation (for removing screws).
- Locked: When the switch is in the center position, the trigger is locked, preventing accidental startup.
Figure 6.1: The forward/reverse switch allows for tightening (right), locking (center), and loosening (left).
6.3. Speed Selection (L/H 2-Speed Gear Selector)
The drill features a two-speed gearbox (position 7 in Figure 4.1) to match the application requirements.
- Low Speed (L): Select 'L' for applications requiring higher torque, such as driving screws or drilling larger holes (0-450 RPM).
- High Speed (H): Select 'H' for faster drilling in softer materials or smaller holes (0-1500 RPM).
Figure 6.2: The L/H 2-speed gear selector. 'L' (0-450 RPM) is recommended for screwing, and 'H' (0-1500 RPM) is recommended for drilling. Note: Not suitable for concrete walls.
6.4. Torque Adjustment
The torque adjustment ring (position 2 in Figure 4.1) allows you to set the amount of rotational force before the clutch disengages, preventing overtightening or stripping screws.
- Rotate the ring to select one of the 23 torque settings for screwdriving.
- Select the drill symbol for maximum torque when drilling.
- Start with a lower torque setting and increase as needed for the material and screw size.
Figure 6.3: The 23+1 torque setting provides precision control for different materials such as plastic, plasterboard, wood, and metal.
6.5. Drilling and Screwdriving Guidelines
- This cordless drill is suitable for drilling into wood and plastic, and for screw tightening and removal.
- It is not suitable for masonry or concrete.
- Apply steady, even pressure when drilling or driving.
- Do not touch freshly used drill bits immediately as they may be hot.
