Electronic function
Active Feedback sensing Technology
CAUTION:
Hold the tool firmly until the rotation stops.
The tool electronically detects situations where the wheel
or accessory may be at risk to be bound. In such situation,
the tool automatically shuts off the power to prevent further
rotation of the spindle (this does not prevent kickback).
At this time, the indication lamp blinks in red and shows
the Active Feedback sensing Technology is working.
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.
Accidental re-start preventive
function
When plugging in the tool while the switch is ON, the
tool does not start.
At this time, the indication lamp blinks in red and shows
that the accidental re-start preventive function works.
To start the tool, turn off the switch, and turn it on again.
Constant speed control
Possible to get fine finish, because the rotating speed is
kept constant even under the loaded condition.
Soft start feature
Soft start feature reduces starting reaction.
Mechanical brake
Only for model GA4591 / GA5091
Mechanical brake is activated after the tool is switched
off.
The brake does not work when the power supply is shut
down with the switch still on.
