Switch action
CAUTION:
Before plugging in the tool, always
check to see that the switch lever actuates properly
and returns to the "OFF" position when released.
CAUTION:
For your safety, this tool is equipped
with lock-off lever which prevents the tool from unin-
tended starting. NEVER use the tool if it runs when
you simply pull the switch lever without pulling the
lock-off lever. Return the tool to our authorized ser-
vice center for proper repairs BEFORE further usage.
CAUTION:
Do not pull the switch lever hard
without pulling the lock-off lever. This can cause
switch breakage.
CAUTION:
NEVER tape down or defeat pur-
pose and function of lock-off lever.
To prevent the switch lever from being accidentally
pulled, a lock-off lever is provided.
To start the tool, pull the lock-off lever toward the opera-
tor and then pull the switch lever.
To stop the tool, release the switch lever.

Electronic function
Active Feedback sensing Technology
CAUTION:
Hold the tool firmly until the rota-
tion 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 modelGA4593 / GA4594 / GA5093 / GA5094
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.
