4. Setup
4.1 Battery Installation
The Einhell TP-CS 18/190 Li BL-Solo is supplied without a battery and charger. These are sold separately as part of the Einhell Power X-Change system. Ensure you use a compatible 18V Power X-Change battery.

Figure 4.1: Illustration indicating that the battery and charger are not included with the saw and must be purchased separately.
To install the battery, slide it into the battery slot on the tool until it clicks into place. To remove, press the release button and slide the battery out.
4.2 Saw Blade Installation
Always ensure the battery is removed before changing the saw blade.
- Press and hold the spindle lock button.
- Use the provided wrench to loosen the blade retaining screw.
- Remove the old blade and replace it with a new 190mm carbide saw blade, ensuring the rotation direction matches the arrow on the saw.
- Tighten the retaining screw firmly while holding the spindle lock.

5. Operating Instructions
5.1 Adjusting Cutting Depth and Angle
The saw offers tool-free adjustment for both cutting depth and angle, allowing for versatile applications.
- Cutting Depth: Loosen the depth adjustment lever, set the desired cutting depth (up to 65mm), and secure the lever.
- Cutting Angle: Loosen the angle adjustment lever, tilt the saw base to the desired angle (up to 45°), and secure the lever.

Figure 5.1: The saw allows for tool-free angle adjustment up to 45° and cutting depth adjustment up to 65mm.
5.2 Making a Cut
Ensure your workpiece is securely clamped. Position the saw on the workpiece, align the blade with your cutting line, and start the saw. Guide the saw smoothly through the material, maintaining a firm grip.
