How to use

Ensure the saw is disconnected from power before installing the blade. Verify that the saw accepts a 190 mm blade with a 30 mm arbor and remove the existing blade following the tool manufacturer's instructions. Fit the Makita 190 mm blade onto the arbor, ensuring correct orientation of the teeth and secure the blade flange and locking nut to the recommended torque. Reconnect power and run the saw briefly without load to confirm smooth rotation before cutting. During use, feed material at a steady pace appropriate for the material and blade type.

Usage recommendations

Use appropriate personal protective equipment, including eye and hearing protection and a dust mask when cutting wood and panels. Match blade speed and feed rate to the material being cut. Replace the blade if teeth are damaged, if the blade shows excessive vibration, or if cut quality deteriorates.
