Indicator lamps
Lighted Off
NOTE: Depending on the conditions of use and the
ambient temperature, the indication may differ slightly
from the actual capacity.
NOTE: The first (far left) indicator lamp will blink when
the battery protection system works.
Tool / battery protection system
The tool is equipped with a tool/battery protection sys-
tem. This system automatically cuts off power to the
motor to extend tool and battery life. The tool will auto-
matically stop during operation if the tool or battery is
placed under one of the following conditions:
Overload protection
When the tool or battery is operated in a manner that
causes it to draw an abnormally high current, the tool
automatically stops without any indication. In this sit-
uation, 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 or battery is overheated, the tool stops
automatically and the lamp blinks. In this case, let the
tool and battery cool before turning the tool on 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.
Switch action
CAUTION:
Before installing the battery cartridge
into the tool, always check to see that the slide switch
moves properly and returns to the "OFF" position
when the rear of the slide switch is depressed.

Lighting up the front lamp
► Fig.4: 1. Lamp
CAUTION:
Do not look in the light or see the
source of light directly.
Turn on the switch to light up the lamp. The lamp keeps
on lighting while the switch is on. The lamp goes out
approximately 10 seconds after turning off the switch.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
NOTE: When the tool is overheated, the lamp blinks
for one minute. In this case, cool down the tool before
another operation.
Accidental re-start preventive
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 function
The tool is equipped with the electronic functions for
easy operation.
• Soft start
The soft-start function minimizes start-up shock,
and makes the tool start smoothly.

Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
