5.3 Installing/Removing Drill Bits
- Installation: Rotate the chuck counter-clockwise to open the jaws. Insert the desired drill bit or screwdriver bit into the chuck. Rotate the chuck clockwise to tighten the jaws firmly around the bit.
- Removal: Rotate the chuck counter-clockwise to loosen the jaws and remove the bit.
6. Operation
6.1 Powering On/Off and Speed Control
The drill driver is activated by pressing the trigger switch. The speed is variable depending on how far the trigger is pressed. Release the trigger to turn off the tool.
6.2 Gear Selection
Use the gear selector switch located on top of the tool to choose between two speed settings:
- Gear 1 (Low Speed): 0-360 RPM, suitable for high-torque applications like driving large screws or drilling large holes.
- Gear 2 (High Speed): 0-1400 RPM, suitable for faster drilling in softer materials or smaller screws.
Note: Always ensure the tool is stopped before changing gear settings.
6.3 Clutch Settings
The clutch collar allows you to select the appropriate torque setting for your task. Rotate the collar to align the desired number with the indicator mark. Higher numbers provide more torque. The drill symbol bypasses the clutch for maximum torque when drilling.
- Settings 1-10: For driving screws, adjust the setting to prevent overtightening or stripping screw heads. Start with a lower setting and increase if needed.
- Drill Symbol: For drilling holes, provides maximum torque without clutch engagement.
6.4 Forward/Reverse Control
The forward/reverse lever, located above the trigger, controls the direction of rotation. Push it to the left for forward (tightening) and to the right for reverse (loosening). Center position locks the trigger for safety.
6.5 Work Light
The integrated LED work light illuminates the work area when the trigger is pressed, improving visibility in dimly lit conditions.
