FUNCTIONAL
DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and
the battery cartridge is removed before adjust-
ing or checking function on the tool.
Installing or removing battery
cartridge
► Fig.1: 1. Button 2. Red indicator 3. Battery cartridge
CAUTION:
• Always switch off the tool before installing or
removing of the battery cartridge.
• Hold the tool and the battery cartridge firmly
when installing or removing battery car-
tridge. Failure to hold the tool and the battery
cartridge firmly may cause them to slip off your
hands and result in damage to the tool and
battery cartridge and a personal injury.
To remove the battery cartridge, slide it from the tool
while sliding the button on the front of the cartridge.
To install the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Insert it all the way until it locks in place
with a little click. If you can see the red indicator on the
upper side of the button, it is not locked completely.
CAUTION:
• Always install the battery cartridge fully until the
red indicator cannot be seen. If not, it may acci-
dentally fall out of the tool, causing injury to you
or someone around you.
• Do not install the battery cartridge forcibly. If the
cartridge does not slide in easily, it is not being
inserted correctly.
Battery protection system
The tool is equipped with a battery protection system. This system
automatically cuts off power to the motor to extend battery life.
The tool will automatically stop during operation if the tool and/
or battery are placed under one of the following conditions:
• Overloaded:
The tool is operated in a manner that causes
it to draw an abnormally high current.
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.
If the tool does not start, the battery is over-
heated. In this situation, let the battery cool
before turning the tool on again.
• Low battery voltage:
The remaining battery capacity is too low
and the tool will not operate. In this situation,
remove and recharge the battery.
NOTE: The overheat protection works only with a
battery cartridge with a star mark.
► Fig.2: 1. Star marking
Indication lamp with multi function
► Fig.3: 1. Indication lamp
Indication lamps are located in two positions.
When the battery cartridge is inserted on the tool with
the slide switch positioned in the "O (OFF)", the indica-
tion lamp flickers quickly for approximately one second.
If it does not flicker so, the battery cartridge or indication
lamp may be broken.
— Overload protection
— When the tool becomes overloaded, the
indication lamp lights up. When the load on
the tool is reduced, the lamp goes out.
— If the tool continues to be overloaded and
the indication lamp continues to light up for
approximately two seconds, the tool stops.
This prevents the motor and its related parts
from being damaged.
— In this situation, move the slide switch to the
"O (OFF)" position once. And then move it to
the "I (ON)" position again to restart.
— Battery cartridge replacing signal
— When the remaining battery capacity is low,
the indicator lamp lights up during operation
earlier than that of high battery capacity.
— Accidental re-start preventive function
— Even if the battery cartridge is inserted on
the tool with the slide switch in the "I (ON)"
position, the tool does not start. In this situa-
tion, the lamp flickers slowly. It indicates that
the accidental re-start preventive function is
at work.
— To start the tool, first slide the slide switch
toward the "O (OFF)" position and then slide
it toward the "I (ON)" position.
Shaft lock
► Fig.4: 1. Shaft lock
CAUTION:
• Never actuate the shaft lock when the spindle is
moving. The tool may be damaged.
Press the shaft lock to prevent spindle rotation when
installing or removing accessories.
Switch action
► Fig.5: 1. Slide switch
CAUTION:
• Before inserting the battery cartridge into the
tool, always check to see that the slide switch
actuates properly and returns to the "OFF"
position when the rear of the slide switch is
depressed.
To start the tool, slide the slide switch toward the "I
(ON)" position. For continuous operation, press the
front of the slide switch to lock it.
To stop the tool, press the rear of the slide switch, then
slide it toward the "O (OFF)" position.
