Work Area Safety
●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 flamma-
ble 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.
Personal Safety
●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 inat-
tention while operating power tools
may result in serious personal
injury.
●Dress properly. Do not wear
loose clothing or jewelry. Con-
tain long hair. Keep your hair,
clothing, and gloves away from
moving parts. Loose clothes, jew-
elry, or long hair can be caught in
moving parts.
●Do not overreach. Keep proper
footing and balance at all
times. Proper footing and bal-
ance enables better control on
the tool in unexpected situations.
General Safety Rules ●Use safety equipment. Always
wear eye protection. Dust mask,
non-skid safety shoes, hard hat,
or hearing protection must be
used for appropriate conditions.
Tool Use and Care
●Use clamps or other practical
ways to secure and support the
work piece to a stable platform.
Holding the work piece by hand
or against your body is unstable
and may lead to loss of control.
●Do not force tools. Use the cor-
rect tool for your application. The
correct tool will do the job better and
safer at the rate for which it is de-
signed.
●Do not use tool if switch does
not turn it on or off. Any tool
that cannot be controlled with the
switch is dangerous and must be
repaired.
●Store idle tools out of reach of
children and other untrained
persons. Tools are dangerous in
the hands of untrained users.
●Check for misalignment or bind-
ing of moving parts, breakage of
parts, and any other condition
that may affect the tool opera-
tion. If damaged, have the tool
serviced before using. Many acci-
dents are caused by poorly main-
tained tools.
• Use only Signature Series rec-
ommended accessories for
your model tool. Accessories
that may be suitable for one tool,
may become hazardous when
used on another tool.
WARNING! READ ALL INSTRUCTIONS. Always observe the safety regulations
applicable in your country to reduce the risk of fire, electric shock, and personal
injury. Understand the following safety instructions before attempting to operate
this product. Always wear eye protection when working with power tools. Keep
these instructions in a safe place.

all instructions and cautionary
markings on batteries, chargers,
and products using batteries.
●Do not allow anything to cover or
clog the charger vents.
●Do not expose charger to rain,
snow, or wet conditions.
●To reduce the risk of damage to
electric plug and cord, pull by plug
rather than cord when disconnect-
ing charger.
●Use of an attachment not recom-
mended or sold by the manufac-
turer may result in a risk of fire,
electric shock, or injury to per-
sons.
●Make sure cord for charger is lo-
cated so that it will not be stepped
on, tripped on, tripped over, or
otherwise subjected to damage or
stress.
Additional Safety Rules
●Do not abuse the power cord. Nev-
er use the cord to carry the charger.
Keep cord away from heat, oil,
water, sharp edges, or moving
parts. Replace damaged cords im-
mediately.
●Do not operate charger if it has
been damaged in any way. Take it
to a qualified service center for
repair.
●To reduce risk of electric shock,
unplug charger from outlet before
attempting any maintenance or
cleaning. Turning off controls will
not reduce this risk.
●Do not disassemble charger or bat-
tery cartridge. Take it to a qualified
service center when repair is re-
quired. Incorrect reassembly may
result in a risk of electric shock or
fire.
Battery Pack
●Do not charge battery pack when
temperature is below 0°C (32°F)
or above 40°C (104°F).

Li-ion Battery Pack
NOTE: Your battery pack is not
fully charged at the time of pur-
chase. Be sure to charge battery
before first use.
●Batteries should be charged in
ambient temperatures between 0°
C (32°F) and 40°C (104°F). Charg-
ing outside this range will result in
either less than full charge or dam-
age to the battery pack.
●Allow the charger to cool when
charging more than two battery
packs consecutively.
●Do not insert finger/body parts or
foreign objects into contact area
of charger.
1. Place charger in a relatively cool
and well-ventilated area.
2. Plug charger into the AC outlet.
CAUTION: Ensure that the pow-
er source to be utilized conforms
to the power requirement speci-
fied on the charger nameplate.
3. Turn the battery upside-down
and slide the battery into charger
while keeping the alignment
marks line up. Slide the forward
in the direction of the arrow. Do
not force battery: It should slide
easily into place with nominal
force. Any difficulty doing so
indicates incorrect alignment.
4. If the power lamp (RED) does
not light immediately or goes out
soon after the charger is
plugged in, consult a Signature
Series authorized dealer.
5. During charging, the charging
lamp (GREEN) will start flash-
ing. When charging is complet-
ed, an internal electronic switch
will automatically be triggered to
prevent overcharging.
- Charging will not start if the
battery pack is warm. For exam-
ple, immediately after high duty
cycle operation. The YELLOW
standby lamp will flash until the
battery temperature drops to
where safe charging is possible.
6. If the temperature of the battery
pack is 0oC (320F) or less,
charging will take longer to fully
charge the battery pack than
standard charging time. At this
low temperature, even when the
battery is fully charged, it will
have approximately 50% of the
power of a fully charged battery
at normal operation tempera-
tures.
7. Once the battery is fully
charged, the GREEN lamp will
light to indicate the charger has
entered into a trickle charge
mode.
