Compatible with engine generators*

  • Equipped with our original, compact and high efficiency inverter circuit, the disk grinder works with an engine generator that doesn’t have an on-board inverter.

    Compatible with Engine Generators
    • When using the brushless motor tools with engine generators whose output voltage can be adjusted, excessive voltage could cause these tools to fail.

Stable operation even during voltage drop

  • The brushless motor runs cooler, and its performance isn't affected as much by voltage drop from long extension cords on site. This vastly improves electrical efficiency.

    Stable Performance during Voltage Drops

High Level of Safety

  • 1. Brake System
    Reduces the time required for the motor to stop when the tool is turned off, enabling more efficient work.

  • Use only the wheel washer supplied (No.374314) with the tool. Please do not use any other wheel washers.

    Wheel Washer
  • 2. 0-Voltage Restart Protection
    Prevents the tool from restarting after the power has been temporarily cut off during operation to avoid accidents.

  • 3. Kickback Protection
    Detects a sudden drop in motor rotation speed and rapidly stops the motor to reduce the reaction force (kickback).

Depending on operating conditions, the Kickback Protection System may not work or provide specified performance. Ensure that the workpiece is properly placed and supported and that the main unit is held firmly during operation. Please carefully read KICKBACK AND RELATED WARNINGS in the instruction manual.
  • 4. Trigger Switch with Off-Lock
    Prevents an accidental start, which may cause a serious injury or accident.

  • 5. Overload Protection

  • 6. Soft Start
