Electric brake
This tool is equipped with an electric wheel brake. If the
tool consistently fails to quickly stop wheel after switch
trigger release, have tool serviced at a Makita service
center.
Electronic function
Constant speed control (For models
GA5020C/GA5021C/GA6020C)
Possible to get fine finish, because the rotating
•
speed is kept constantly even under the loaded
condition.
Additionally, when the load on the tool exceeds
•
admissible levels, power to the motor is reduced to
protect the motor from overheating. When the load
returns to admissible levels, the tool will operate as
normal.
Soft start feature
Soft start because of suppressed starting shock.

Indication lamp
1
008416
The indication lamp lights up green when the tool is
plugged. If the indication lamp does not light up, the
mains cord or the controller may be defective. The
indication lamp is lit but the tool does not start even if the
tool is switched on, the carbon brushes may be worn out,
or the controller, the motor or the ON/OFF switch may be
defective.
Unintentional restart proof
Even locking lever keeping the switch trigger depressed
(Lock-on position) does not allow the tool to restart even
when the tool is plugged.
At this time, the indication lamp flickers red and shows
the unintentional restart proof device is on function.
To cancel the unintentional restart proof, pull the switch
trigger fully, then release it.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and
•
unplugged before carrying out any work on the
tool.
