NOTICE:
If the tool is operated continuously at
low speed for a long time, the motor will get over-
loaded, resulting in tool malfunction.
NOTICE:
The speed adjusting dial can be turned
only as far as 5 and back to 1. Do not force it past
5 or 1, or the speed adjusting function may no
longer work.
Electric brake
Electric brake is activated after the tool is switched off.
The brake does not work when the power supply is shut
down, such as the battery is removed accidentally, with
the switch still on.
If the tool consistently fails to quickly stop after turning
off the switch, have the tool serviced at a Makita Service
Center.

ON, the tool does not start.
To start the tool, turn off the switch, and turn it on again.

wheel or accessory may be at risk to be bound. In the
situation, the tool is automatically shut off to prevent

To restart the tool, switch off the tool first, remove the
cause of sudden drop in the rotation speed, and then
turn the tool on.
