3. Keep bystanders, children, and visitors
away while operating a power tool. Distrac-
tions can cause you to lose control.
Tool Use and Care
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.
Electrical Safety
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
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.
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.
16. Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
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.
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.
9. Remove adjusting keys or wrenches
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.
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.
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.
20. Use only accessories that are recom-
mended by the manufacturer for your
model. Accessories that may be suitable for
one tool may create a risk of injury when
used on another tool.
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
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.
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.
SPECIFIC SAFETY RULES
USB029-2
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to cordless recipro saw
safety rules. If you use this tool unsafely or incorrectly, you can
suffer serious personal injury.
1. Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring.
Contact with a “live” wire will make exposed
metal parts of the tool “live” and shock the
operator.
10. Always switch off and wait for the blade to
come to a complete stop before removing
the blade from the workpiece.
11. Do not touch the blade or the workpiece
immediately after operation; they may be
extremely hot and could burn your skin.
2. Be aware that this tool is always in an
operating condition, because it does not
have to be plugged into an electrical out-
let.
12. Some material contains chemicals which
may be toxic. Take caution to prevent
dust inhalation and skin contact. Follow
material supplier safety data.
3. Always use safety glasses or goggles.
Ordinary eye or sun glasses are NOT
safety glasses.
4. Avoid cutting nails. Inspect workpiece for
any nails and remove them before opera-
tion.
5. Do not cut oversize workpiece.
6. Check for the proper clearance beyond the
workpiece before cutting so that the blade
will not strike the floor, workbench, etc.
7. Hold the tool firmly.
8. Make sure the blade is not contacting the
workpiece before the switch is turned on.
9. Keep hands away from moving parts.

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.
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.

When the blade loses its cutting efficiency in one place along
its cutting edge, reposition the shoe to utilize a sharp,
unused portion of its cutting edge. This will help to lengthen
the life of the blade. To reposition the shoe, loosen the lever
counterclockwise and slide the shoe forward or back to the
desired position. Then tighten the lever clockwise to firmly
secure the shoe.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.
