3. Hold power tool by insulated gripping surfaces,

when performing an operation where the cutting
accessory may contact hidden wiring. Cutting

accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the
operator an electric shock.

4. Hold power tool by insulated gripping surfaces,

when performing an operation where the fastener
may contact hidden wiring. Fasteners contacting a

“live” wire may make exposed metal parts of the

IMPORTANT SAFETY
INSTRUCTIONS ENC007-9

FOR BATTERY CARTRIDGE

1. Before using battery cartridge, read all

instructions and cautionary markings on (1)

battery charger, (2) battery, and (3) product using

battery.

2. Do not disassemble battery cartridge.

3. If operating time has become excessively shorter,

stop operating immediately. It may result in a risk

of overheating, possible burns and even an

explosion.

4. If electrolyte gets into your eyes, rinse them out

with clear water and seek medical attention right

away. It may result in loss of your eyesight.

5. Do not short the battery cartridge:

(1) Do not touch the terminals with any

conductive material.

(2) Avoid storing battery cartridge in a container

with other metal objects such as nails, coins,
etc.

(3) Do not expose battery cartridge to water or

rain.
A battery short can cause a large current flow,
overheating, possible burns and even a
breakdown.

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 a damaged battery.

10. Follow your local regulations relating to disposal

of battery.

SAVE THESE INSTRUCTIONS.

Tips for maintaining maximum battery life

1. Charge the battery cartridge before completely

discharged.
Always stop tool operation and charge the battery
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

temperature at 10°C - 40°C (50°F - 104°F). Let a hot
battery cartridge cool down before charging it.

4. Charge the battery cartridge if you do not use it for

a long period (more than six months).

FUNCTIONAL DESCRIPTION

CAUTION:

• Always be sure that the tool is switched off and the
battery 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
cartridge does not slide in easily, it is not being inserted
correctly.

Battery protection system (Lithium-ion
battery with star marking) (Fig. 2)

Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically cuts
off power to the tool 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, release the switch trigger on the tool
and stop the application that caused the tool to
become overloaded. Then pull the switch trigger
again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
switch trigger 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.

Indicating the remaining battery capacity

(Only for battery cartridges with “B” at the end of the
model number.) (Fig. 3)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for few seconds.
