Electric brake
This tool is e uipped with an electric brake. If the
tool consistently fails to uickly cease to function
after the switch trigger is released, have the tool
serviced at a Makita service center.
Constant speed control
The speed control function provides the constant
rotation speed regardless of load conditions.
Active Feedback sensing Technology
The tool electronically detects situations in which
the cutting wheel may be at risk to be bound.

the cause of sudden drop in the rotation speed, and
then pull the switch trigger to restart the tool.

ing wheel, cutting stability, precise control over cutting
depth, and dust e traction solutions, especially at tile,
plaster, stoneware cuttings.
