5. Setup
5.1. Attaching/Removing Drill Bits or Screwdriver Bits
- Ensure the tool is unplugged from the power source before making any adjustments.
- Rotate the chuck collar counter-clockwise to open the chuck jaws.
- Insert the desired drill bit or screwdriver bit into the chuck. Ensure the bit is inserted as far as possible for maximum grip and stability.
- Rotate the chuck collar clockwise to tighten the chuck jaws securely around the bit. Hand-tighten firmly.
- To remove a bit, rotate the chuck collar counter-clockwise until the jaws open sufficiently to release the bit.
5.2. Selecting Clutch Setting
The clutch ring allows you to select the appropriate torque setting for your task. Rotate the clutch ring to align the desired number with the indicator mark on the drill body. Lower numbers are for driving small screws or working with soft materials, while higher numbers are for driving larger screws or drilling into harder materials. The drill symbol setting is for drilling applications, providing maximum torque.
6. Operating Instructions
6.1. Powering On/Off and Speed Control
- Plug the tool into a suitable power outlet.
- To start the tool, press the variable speed trigger switch. The speed of the tool increases as you press the trigger further.
- To stop the tool, release the trigger switch.
6.2. Forward/Reverse Rotation
A forward/reverse switch is located above the trigger. Push the switch 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).
6.3. Drilling and Screwdriving Tips
- Always hold the tool firmly with both hands, especially when drilling.
- Apply steady, even pressure. Do not force the tool.
