9. Remove adjusting keys or wrenches
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. Distrac-
tions 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
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
shock or injury.
20. Use only accessories that are recom-
mended by the manufacturer for your
model. Accessories that may be suitable for

IMPORTANT SAFETY INSTRUCTIONS FOR
CHARGER & BATTERY CARTRIDGE
USC002-3
1. SAVE THESE INSTRUCTIONS- This man-
ual contains important safety and operat-
ing instructions for battery charger.

2. Before using battery charger, read all
instructions and cautionary markings on
(1) battery charger, (2) battery, and (3)
product using battery.
7. Make sure cord is located so that it will
not be stepped on, tripped over, or other-
wise subjected to damage or stress.
8. An extension cord should not be used
unless absolutely necessary. Use of
improper extension cord could result in a
risk of fire and electric shock. If extension
cord must be used, make sure:
3. CAUTION - To reduce risk of injury, charge
only MAKITA rechargeable batteries
marked on the charger label. Other types
of batteries may burst causing personal
injury and damage.
a. That pins on plug of extension cord
are the same number, size, and shape
as those of plug on charger;
4. Do not expose charger to rain or snow.
5. Use of an attachment not recommended
or sold by the battery charger manufac-
turer may result in a risk of fire, electric
shock, or injury to persons.

charger from outlet before attempting any
maintenance or cleaning. Turning off con-
trols will not reduce this risk.
16. If electrolyte gets into your eyes, rinse
them out with clear water and seek medi-
cal attention right away. It may result in
loss of your eyesight.
13. The battery charger is not intended for
use by young children or infirm persons

•
Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Charging
Before using battery charger, read all instructions and cau-
tionary markings on the battery charger.
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.
5. Always stop tool operation and charge the battery car-
tridge when you notice that the warning lamp lightened up.
Refresh charging
Refreshing battery adapter (optional accessory) can refresh
an inactive battery cartridge.
•
•
Refresh charging should be done once a week.
When you charge a new battery cartridge or a battery
cartridge that has not been used for a long time, it may
not accept a full charge. In this case, refresh charging
must be done. The battery cartridge may decrease the
tool performance, because the chemical substance of
the battery cartridge is inactive.
