2.1 Battery Installation

The die grinder operates on an 18V Lithium-Ion battery (not included with bare tool). To install the battery:

1. Ensure the tool is switched off.
2. Align the battery pack with the battery slot on the tool handle.
3. Slide the battery into the slot until it clicks securely into place.
4. To remove, press the battery release button and slide the battery out.

2.2 Accessory Installation

The die grinder is designed for use with various accessories such as carbide burrs, abrasive discs, and flap wheels. Always ensure the accessory is rated for the tool's maximum rotational speed.

1. Ensure the tool is switched off and the battery is removed.
2. Press and hold the spindle lock button located near the collet.
3. Using the appropriate wrench (typically supplied with the tool), loosen the collet nut by turning it counter-clockwise.
4. Insert the shank of the accessory fully into the collet.
5. While still holding the spindle lock, tighten the collet nut clockwise with the wrench until the accessory is securely fastened. Do not overtighten.
6. Release the spindle lock button.

2.3 Side Handle Attachment

The die grinder comes with a removable side handle for improved control and comfort.

1. Locate the threaded hole on the side of the grinder's head.
2. Screw the side handle into this hole until it is firmly attached.
3. Adjust the handle's position for optimal grip and balance during operation.

3. Operating Instructions

3.1 Powering On/Off

The die grinder features a sliding switch for operation.

• To turn on: Slide the switch forward to the "ON" position.
• To turn off: Slide the switch backward to the "OFF" position.

Note: The tool operates at a single speed (10,000 RPM maximum rotational speed).

3.2 Safety Features

This tool is equipped with several safety mechanisms:

• S-Automatic Safety Shutdown: If the accessory jams during operation, the tool will automatically shut off to prevent kickback and motor damage. Release the switch and clear the obstruction before restarting.
• Restart Protection: If the battery is removed and reinserted, or if power is interrupted while the switch is in the "ON" position, the tool will not restart automatically. You must cycle the switch to "OFF" and then back to "ON" to resume operation.
• Thermal Overload Protection: If the motor becomes too hot due to prolonged heavy use, the tool will reduce power or shut down to prevent damage. Allow the tool to cool down before resuming work.

3.3 General Operation Tips

• Always wear appropriate personal protective equipment (PPE), including safety glasses, hearing protection, and gloves.
• Secure your workpiece firmly before beginning any grinding operation.
• Apply steady, even pressure. Avoid excessive force, which can lead to jamming or reduced performance.
• Keep ventilation slots clear to ensure proper motor cooling.
• Do not operate the tool in damp or wet conditions.
