6. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
7. Do not incinerate the battery cartridge even if it
is severely damaged or is completely worn out.
The battery cartridge can explode in a fire.
8. Be careful not to drop or strike battery.
9. Do not use damaged battery.
10. Follow your local regulations relating to disposal
of battery.

Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat-
tery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room tempera-
ture at 10°C – 40°C (50°F – 104°F). Let a hot bat-
tery cartridge cool down before charging it.
4. Charge the battery cartridge once in every six
months if you do not use it for a long period of
time.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before adjusting or checking
function on the tool.
Installing or removing battery cartridge (Fig. 1)
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 cartridge. 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 accidentally fall
out of the tool, causing injury to you or someone
around you.
• Do not install the battery cartridge forcibly. If the car-
tridge does not slide in easily, it is not being inserted
correctly.
Battery protection system (Fig. 2)
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:
6
• 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 applica-
tion that caused the tool to become overloaded. Then
turn the tool on to restart.
If the tool does not start, the battery is overheated. 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 car-
tridge with a star mark.
Switch action (Fig. 3)
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the slide switch actuates prop-
erly and returns to the "OFF" position when the rear of
the slide switch is depressed.
• Switch can be locked in "ON" position for ease of oper-
ator comfort during extended use. Apply caution when
locking tool in "ON" position and maintain firm grasp on
tool.
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.
Indication lamp with multi function (Fig. 4)
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)" position, the indi-
cation lamp flickers quickly for approximately one sec-
ond. If it does not flicker so, the battery cartridge or
indication lamp has broken.
– Overload protection
– When the tool is 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 indica-
tion 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 case, to start the tool again, move the slide
switch to the "O (OFF)" position once and then to the
"I (ON)" position.
– Battery cartridge replacing signal
– When the remaining battery capacity gets small, the
indicator lamp lights up during operation earlier than
enough capacity battery use.
– 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. At this time, the lamp flickers slowly
and this shows 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.
