Work Area
before turning the tool on. A wrench or a
key that is left attached to a rotating part of
the tool may result in personal injury.
1. Keep your work area clean and well lit.
Cluttered benches and dark areas invite acci-
dents.
10. Do not overreach. Keep proper footing
and balance at all times. Proper footing and
balance enable better control of the tool in
unexpected situations.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the dust
or fumes.
11. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions.
3. Keep bystanders, children, and visitors
away while operating a power tool. Dis-
tractions can cause you to lose control.
Tool Use and Care
Electrical Safety
12. Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or
against your body is unstable and may lead
to loss of control.
4. A battery operated tool with integral bat-
teries or a separate battery pack must be
recharged only with the specified charger
for the battery. A charger that may be suit-
able for one type of battery may create a risk
of fire when used with another battery.
13. Do not force tool. Use the correct tool for
your application. The correct tool will do the
job better and safer at the rate for which it is
designed.
5. Use battery operated tool only with specif-
ically designated battery pack. Use of any
other batteries may create a risk of fire.
14. Do not use tool if switch does not turn it
on or off. A tool that cannot be controlled
with the switch is dangerous and must be
repaired.
Personal Safety
6. Stay alert, watch what you are doing, and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
15. Disconnect battery pack from tool or
place the switch in the locked or off posi-
tion before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
7. Dress properly. Do not wear loose cloth-
ing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from
moving parts. Loose clothes, jewelry, or
long hair can be caught in moving parts.
16. Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
17. When battery pack is not in use, keep it
away from other metal objects like: paper
clips, coins, keys, nails, screws, or other
small metal objects that can make a con-
nection from one terminal to another.
Shorting the battery terminals together may
cause sparks, burns, or a fire.
8. Avoid accidental starting. Be sure switch
is in the locked or off position before
inserting battery pack. Carrying tools with
your finger on the switch or inserting the bat-
tery pack into a tool with the switch on invites
accidents.

18. Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools with sharp cutting edge are less likely to
bind and are easier to control.
one tool may create a risk of injury when
used on another tool.
Service
21. Tool service must be performed only by
qualified repair personnel. Service or main-
tenance performed by unqualified personnel
may result in a risk of injury.
19. Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tool’s
operation. If damaged, have the tool ser-
viced before using. Many accidents are
caused by poorly maintained tools.
22. When servicing a tool, use only identical
replacement parts. Follow instructions in

3. Battery charger
3. When the battery cartridge is inserted, the charging light
color will change from green to red and charging 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.
7
NOTE:
•
The battery charger is for charging Makita battery
cartridge. Never use it for other purposes or for other
manufacturer’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 location
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 battery charger.
If the charging light flashes alternately in green and red
color, 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.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely dis-
charged.
Always stop tool operation and charge the battery car-
tridge 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 Nickel Metal Hydride battery cartridge when
you do not use it for more than six months.
