5. Do not short the battery cartridge:
(1) Do not touch the terminals with any conduc-
tive 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 break-
down.
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, shake or strike battery.
9. Do not charge inside a box or container of any
kind. The battery must be placed in a well venti-
lated area during charging.
ADDITIONAL SAFETY RULES FOR TOOL
ENB022-1
1. Be aware that this tool is always in an operating
condition, because it does not have to be
plugged into an electrical outlet.
2. Hold tool by insulated gripping surfaces when
performing an operation where the cutting tool
may contact hidden wiring. Contact with a "live"
wire will also make exposed metal parts of the
tool "live" and shock the operator.
3. Always be sure you have a firm footing.
4. Be sure no one is below when using the tool in
high locations.
5. Hold the tool firmly.
6. Keep hands away from rotating parts.
7. Do not leave the tool running. Operate the tool
only when hand-held.
8. Do not touch the drill bit or the workpiece imme-
diately after operation; they may be extremely
hot and could burn your skin.

OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while pressing the buttons on both sides of the car-
tridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Charging (Fig. 2)
1. Plug the battery charger into the proper AC voltage
source. The charging light will flash in green color.
2. Insert the battery cartridge so that the plus and
minus terminals on the battery cartridge are on the
same sides as their respective markings on the high
capacity battery charger. Insert the cartridge fully
into the port so that it rests on the charger port floor.
3. When the battery cartridge is inserted, the charging
light color will change from green to red and charg-
ing will begin. The charging light will remain lit
steadily during charging.
4. When the charging light color changes from red to
green, the charging cycle is complete.
5. If you leave the battery cartridge in the charger after
the charging cycle is complete, the charger will
switch into its "trickle charge (maintenance charge)"
mode which will last approximately 24 hours.
6. After charging, unplug the charger from the power
source.
NOTE:
• The battery charger is for charging Makita battery car-
tridge. Never use it for other purposes or for other man-
ufacturer's batteries.
• When you charge a new battery cartridge or a battery
cartridge which has not been used for a long period of
time, it may not accept a full charge. This is a normal
condition and does not indicate a problem. You can
recharge the battery cartridge fully after discharging it
completely and recharging a couple of times.
• If you charge a battery cartridge from a just operated
tool or a battery cartridge which has been left in a loca-
tion exposed to direct sunlight or heat for a long time,
the charging light may flash in red color. If this occurs,
wait for a while. Charging will begin after the battery
cartridge cools. The battery cartridge will cool faster if
you remove the battery cartridge from the high capacity
battery charger.
• If the charging light flashes alternately in green and red
color, a problem exists and charging is not possible.
The terminals on the charger or battery cartridge are
clogged with dust or the battery cartridge is worn out or
damaged.
Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent
spontaneous discharging after full charge, the charger
will switch into its "trickle charge (maintenance charge)"
mode and keep the battery cartridge fresh and fully
charged.
