This manual provides essential instructions for the safe and efficient operation of the FLEX CS 68 18-EC cordless circular saw. Always read the safety instructions before use. Ensure the battery is charged and the blade is correctly installed before starting any work.

Setup and Operation
Battery Installation
Insert the charged battery into the tool until it clicks into place. To remove, press the release button and pull the battery out.
Installing the Blade
Warning: Use only 190mm saw blades rated for 5800/min (RPM) or greater. Use protective gloves when handling the blade.
- Remove the blade wrench from its storage area.
- Press the shaft-lock button and use the wrench to turn the blade until the shaft-lock engages.
- Turn the wrench counterclockwise to remove the blade stud and outer washer.
- Retract the lower guard, slide the blade through the foot slot, and mount it against the inner washer.
- Reinstall the outer washer, tighten the stud by hand, and then tighten an additional 1/8 turn (45°) with the wrench.
Adjustments
- Cutting Depth: Loosen the depth-adjustment lever, set the desired depth using the scale, and tighten the lever. Ensure no more than one tooth length extends below the material.
- Cutting Angle: Use the bevel-preset knob for 22.5°, 45°, or 56° settings, or the bevel-adjustment lever for custom angles.
Cutting Techniques
Always hold the saw firmly with both hands. For plunge cuts, set the bevel to zero, align the guide notch, and gradually lower the saw into the material using the front of the foot as a hinge point.
Maintenance and Care
Regularly clean the tool and ventilation slots with dry compressed air. Repairs must be performed by an authorized service center. Dispose of the tool and batteries according to local environmental regulations.
