Tool / battery protection system
The tool is equipped with a tool/battery protection
system. This system automatically cuts off power to
the motor to extend tool and battery life. The tool will
automatically stop during operation if the tool or battery
is placed under one of the following conditions. In some
conditions, the indicators light up.
Overload protection
When the tool is operated in a manner that causes it to
draw an abnormally high current, the tool automatically
stops without any indication. In this situation, turn the
tool off and stop the application that caused the tool to
become overloaded. Then turn the tool on to restart.
Overheat protection
When the tool is overheated, the tool stops automati
-
cally and the battery indicator shows following state. In
this situation, let the tool cool before turning the tool on
again.
On
Blinking
If the tool does not start, the battery may be overheated.
In this situation, let the battery cool before starting the
tool again.
Overdischarge protection
When the battery capacity is not enough, the tool stops
automatically. In this case, remove the battery from the
tool and charge the battery.
Releasing protection lock
When the protection system works repeatedly, the tool
is locked and the battery indicator shows the following
state.
In this situation, the tool does not start even if turning
the tool off and on. To release the protection lock,
remove the battery, set it to the battery charger and wait
until the charging finishes.

High torque mode
This tool has "high speed mode" and "high torque mode". It
automatically changes operation mode depending on the work
load. When mode indicator lights up during operation, the tool
is in high torque mode.

function
Even if the battery cartridge is installed on the tool with the
slide switch in the "I (ON)" position, the tool does not start.
To start the tool, first slide the slide switch toward the "O
(OFF)" position and then slide it toward the "I (ON)" position.
Electronic torque control function
The tool electronically detects situations where the wheel or
accessory may be at risk to be bound. In the situation, the
tool is automatically shut off to prevent further rotation of the
spindle (it does not prevent kickback).
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.
Soft start feature
Soft start feature reduces starting reaction.
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.
