Work Area
■ Keep your work area clean and
well lit. Cluttered benches and
dark areas invite accidents.
■ 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.
■ Keep bystanders, children, and
visitors away while operating a
power tool. Distractions can
cause you to lose control.
Electrical Safety
■ Do not abuse the cord. Never
use the cord to carry the
charger. Keep cord away from
heat, oil, sharp edges, or
moving parts. Replace damaged
cords immediately.
cords may create a fire.
Damaged
■ A battery operated tool with
integral batteries or a separate
battery pack must be recharged
only with the specified charger
for the battery. A charger that
may be suitable for one type of
battery may create a risk of fire
when used with another battery.
Use listed battery only with
charger listed.
■ Use battery operated tool only
with specifically designated
battery pack. Use of any other
batteries may create a risk of
fire. Use only with battery pack.
Personal Safety
■ Stay alert, watch what you are

Tool Use and Care
■ 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.
■ 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.
■ 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.
■ Disconnect battery pack from
tool or place the switch in the
locked or off position before
making any adjustments,
changing accessories, or
storing the tool. Such preventive
safety measures reduce risk of
starting the tool accidentally.
■ Store idle tools out of reach of
children and other untrained
persons. Tools are dangerous in
the hands of untrained users.
■ 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 connection from one
terminal to another. Shorting the
battery terminals together may
cause sparks, burns, or a fire.
■ Maintain tools with care. Keep
cutting tools sharp and clean.
Properly maintained tools, with
sharp cutting edges are less likely
to bind and are easier to control.
■ 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 serviced
before using. Many accidents
are caused by poorly maintained
tools. Use only accessories that
are recommended 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.

SPECIFIC SAFETY RULES AND SYMBOLS
Additional Rules For Safe
Operation
■ Know your power tool. Read
operator’s manual carefully.
Learn its applications and
limitations, as well as the
specific potential hazards
related to this tool. Following this
rule will reduce the risk of electric
shock, fire, or serious injury.
■ Make sure your extension cord
is in good condition. When
using an extension cord, be
sure to use one heavy enough

12
Page 13
To obtain the longest possible battery
life, we suggest the following:
• Store and charge your batteries
in a cool area. Temperatures
above normal room temperature
will shorten battery life.
• Never store batteries in a
discharged condition. Recharge
them immediately after they are
discharged.
• All batteries gradually lose their
charge. The higher the
temperature, the quicker they
lose their charge. If you store
your tool for long periods of time
without using it, recharge the
batteries every month or two.
This practice will prolong battery
life.
To preserve natural resources, please
recycle or dispose of batteries properly.
This product contains nickel-cadmium
batteries. Local, state or federal laws
may prohibit disposal of nickel-cadmium batteries in ordinary trash.
Consult your local waste authority for
information regarding available
recycling and/or disposal options.
BATTERY PACK REMOVAL AND
PREPARATION FOR RECYCLING
WARNING:
disposal, cover the battery pack's
terminals with heavy-duty
adhesive tape. Do not attempt to
destroy or disassemble battery
pack or remove any of its
components. Nickel-cadmium
batteries must be recycled or
disposed of properly. Also, never
touch both terminals with metal
