GENERAL POWER TOOL
WARNING
SAFETY WARNINGS
Read all safety warnings, instruc-
tions provided with this power tool. Failure to follow
all instructions listed below may result in electric shock,
re and/or serious injury. Save all warnings and in
structions for future reference. The term "power tool"
in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
tions, illustrations and specifica-
WORK AREA SAFETY
• Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
• Do not operate power tools in explosive atmo
spheres, such as in the presence of ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
• Power tool plugs must match the outlet. Never modify
the plug in any way. Do not use any adapter plugs with
earthed (grounded) power tools. Unmodied plugs
and matching outlets will reduce risk of electric shock.
• Avoid body contact with earthed or grounded
surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
• Do not abuse the cord. Never use the cord for car
rying, pulling or unplugging the power tool. Keep
cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk
of electric shock.
• When operating a power tool outdoors, use an
extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric shock.
• If operating a power tool in a damp location is
unavoidable, use a ground fault circuit interrupter
(GFCI) protected supply. Use of an GFCI reduces
the risk of electric shock.
PERSONAL SAFETY
• Stay alert, watch what you are doing and use
common sense when operating a power tool. Do
not use a power tool while you are tired or under
the inuence of drugs, alcohol or medication. A
moment of inattention while operating power tools may
result in serious personal injury.
• Use personal protective equipment. Always wear
eye protection. Protective equipment such as a dust
mask, non-skid safety shoes, hard hat or hearing
protection used for appropriate conditions will reduce
personal injuries.
• Prevent unintentional starting. Ensure the switch
is in the off-position before connecting to power
source and/or battery pack, picking up or carrying
the tool. Carrying power tools with your nger on the
switch or energizing power tools that have the switch
on invites accidents.
• Remove any adjusting key or wrench before turning
the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal injury.
• Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewelry. Keep your hair and clothing away from
moving parts. Loose clothes, jewelry or long hair can
be caught in moving parts.
• If devices are provided for the connection of dust
extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection
can reduce dust-related hazards.
• Do not let familiarity gained from frequent use of
-
tools allow you to become complacent and ignore
tool safety principles. A careless action can cause
severe injury within a fraction of a second.
POWER TOOL USE AND CARE
• Do not force the power tool. Use the correct power tool
for your application. The correct power tool will do the
job better and safer at the rate for which it was designed.
-
• Do not use the power tool if the switch does not turn
it on and off. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
• Disconnect the plug from the power source and/
or remove the battery pack, if detachable, from
the power tool before making any adjustments,
changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting
the power tool accidentally.
• Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
• Maintain power tools and accessories. Check for
misalignment or binding of moving parts, breakage
of parts and any other condition that may affect
the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are
caused by poorly maintained power tools.
-
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc.
in accordance with these instructions, taking into
account the working conditions and the work to be
performed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
BATTERY TOOL USE AND CARE
• Recharge only with the charger specied by the
manufacturer. A charger that is suitable for one type
of battery pack may create a risk of re when used with
another battery pack.
• Use power tools only with specically designated
battery packs. Use of any other battery packs may
create a risk of injury and re.
• 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
burns or a re.
• Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, ush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from
the battery may cause irritation or burns.
• Do not use a battery pack or tool that is damaged or
modied. Damaged or modied batteries may exhibit
unpredictable behavior resulting in re, explosion or
risk of injury.
• Do not expose a battery pack or tool to re or
excessive temperature. Exposure to re or temperature
2
above 265°F (130°C) may cause explosion.
WARNING
C
US
• Follow all charging instructions and do not charge
the battery pack or tool outside the temperature
range specied in the instructions. Charging im
properly or at temperatures outside the specied range
may damage the battery and increase the risk of re.
SERVICE
• Have your power tool serviced by a qualied repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
• Never service damaged battery packs. Service
of battery packs should only be performed by the
manufacturer or authorized service providers.
NAILER SAFETY WARNINGS
• Always assume that the tool contains fasteners.
Careless handling of the nailer can result in unexpected
ring of fasteners and personal injury.
• Do not point the tool towards yourself or anyone
nearby. Unexpected triggering will discharge the fas
tener causing an injury.
• Do not actuate the tool unless the tool is placed
rmly against the workpiece. If the tool is not in con
tact with the workpiece, the fastener may be deflected
away from your target.
• Disconnect the tool from the power source when
the fastener jams in the tool. While removing a
jammed fastener, the nailer may be accidentally acti
vated if it is plugged in.
• Use caution while removing a jammed fastener.
The mechanism may be under compression and the
fastener may be forcefully discharged while attempting
to free a jammed condition.
• Do not use this nailer for fastening electrical
cables. It is not designed for electric cable installa
tion and may damage the insulation of electric cables
thereby causing electric shock or re hazards.
•Prior to each use, check workpiece contact and
trigger for correct operation. Do not disassemble or
clamp parts of the workpiece contact, trigger, or driv
ing mechanism. This will cause unexpected actuation,
resulting in serious injury.
•Do not engage in horseplay. The discharged fasten
ers are projectiles capable of causing serious injury.
•Do not remove, tamper with, or otherwise cause
the tool operating controls to become inoperable.
This will cause unexpected actuation, resulting in
serious injury.
•Do not operate a tool if any portion of the tool oper
ating controls is inoperable, disconnected, altered,
or not working properly. This will cause unexpected
actuation, resulting in serious injury.
•Always keep hands and body away from discharge
area of the tool. Never attempt to clear a jammed
workpiece contact by grasping the discharge area of
the tool. Fasteners discharged from tool can cause
serious injury if they contact hands or body.
•Do not drive fasteners close to the edge of the
workpiece. Fasteners can slip off corners and edges
or penetrate through thin material, making them pro
jectiles capable of causing serious injury.
•Use the tool only for the intended purpose. Do not
abuse the tool. Do not use as a hammer, stamp or en
grave information onto parts, drop or impact the tool or
otherwise apply excess force to the tool in use. Do not
mount the tool to stands or modify it for stationary use.
• Maintain labels and nameplates. These carry
important information. If unreadable or missing, contact
a MILWAUKEE service facility for a free replacement.
