4. Setup

4.1 Battery Installation

This tool operates on an 18V Lithium-Ion battery (not included). Ensure you use genuine Makita 18V LXT batteries for optimal performance and safety.

1. Align the battery pack with the battery port on the tool's handle.
2. Slide the battery pack into the port until it clicks securely into place.
3. To remove, press the release button(s) on the side of the battery pack and slide it out.

4.2 Bit Installation (Keyless Chuck)

1. Rotate the chuck counter-clockwise to open the jaws.
2. Insert the drill bit or screwdriver bit fully into the chuck.
3. Rotate the chuck clockwise to tighten the jaws firmly around the bit. Ensure the bit is centered and secure.

4.3 Mode and Torque Selection

• Mode Selector Ring: Rotate the ring behind the chuck to select between drilling (drill icon), hammer drilling (hammer icon), and screwdriving (screw icon).
• Torque Adjustment Ring: For screwdriving, rotate the numbered ring to select the desired torque setting (1-21). Higher numbers indicate higher torque. Use a lower setting for smaller screws or softer materials, and a higher setting for larger screws or harder materials.
• Speed Selector Switch: Located on top of the tool, this switch allows you to select between two mechanical speed ranges: "1" for low speed/high torque (ideal for heavy-duty screwdriving or large diameter drilling) and "2" for high speed/low torque (ideal for fast drilling).

5. Operating Instructions

5.1 Basic Operation

• Trigger Switch: Press the trigger switch to start the tool. The speed increases with increased pressure on the trigger.
• Reversing Switch: Located above the trigger, this switch changes the direction of rotation. Push it to the left for forward (clockwise) rotation and to the right for reverse (counter-clockwise) rotation. Position it in the center to lock the trigger and prevent accidental starting.
• LED Work Light: The integrated LED light illuminates the work area automatically when the trigger is pulled.

5.2 Drilling

• Select the appropriate drill bit for the material (wood, metal, masonry).
• Set the mode selector to the drill icon for wood/metal or the hammer drill icon for masonry.
• Choose the appropriate speed setting (Speed 1 for larger holes, Speed 2 for smaller holes or faster drilling).
• Hold the tool firmly and apply steady, even pressure. Allow the tool to do the work.

5.3 Screwdriving

• Select the appropriate screwdriver bit.
• Set the mode selector to the screwdriving icon.
• Adjust the torque setting according to the screw size and material. Start with a lower setting and increase if necessary.
• Apply firm, steady pressure to prevent the bit from camming out of the screw head.

6. Maintenance
