This manual provides essential instructions for the safe and efficient operation of the FLEX CSM 57 18-EC metal circular saw. Always read the general safety instructions provided in the separate booklet (leaflet no. 315915) before use.

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.
Blade Installation
Use only 136-150 mm metal saw blades rated for 4500/min (RPM) or greater. Use the hex key (18) to operate the shaft-lock button (14) and blade bolt (8). Ensure the blade teeth and arrow point in the same direction as the arrow on the lower guard.
Adjusting Cutting Depth
Loosen the depth-adjustment lever (16), align the indicator on the depth scale (17) with the desired depth, and tighten the lever. The blade should extend about 3 mm below the material being cut.
