GENERAL SAFETY RULES
WORK AREA SAFETY
1. Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
2. Do not operate power tools in explosive atmo-
spheres, such as in the presence of flammable liquids,
gases or dust. Power tools create sparks which may ig-
nite the dust or fumes.
3. Keep children and bystanders away while operating
a power tool. Distractions can cause you to lose control.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. Never mod-
ify the plug in any way. Do not use any adapter plugs
with earthed (grounded) power tools. Unmodified plugs
and matching outlets will reduce risk of electric shock.
2. Avoid body contact with earthed or grounded surfac-
es such as pipes, radiators, ranges and refrigerators.
There is an increased risk of electric shock if your body
is earthed or grounded.
3. Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of elec-
tric shock.
4. 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.
5. When operating a power tool outdoors, use an ex-
tension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric
shock.
6. If operating a power tool in a damp location is un-
avoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of a GFCI reduces the risk of elec-
tric shock.
PERSONAL SAFETY
1. Stay alert, watch what you are doing and use com-
mon sense when operating a power tool. Do not use a
power tool while you are tired or under the influence
of drugs, alcohol or medication. A moment of inatten-
tion while operating power tools may result in serious
personal injury.
2. Use personal protective equipment. Always wear
eye protection. Protective equipment such as a respira-
tory mask, non-skid safety shoes and hearing protection
used for appropriate conditions will reduce the risk of
personal injury.
3. 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 finger on the switch or
energizing power tools that have the switch on invites
accidents.
4. 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.
5. Do not overreach. Keep proper footing and balance
at all times. This enables better control of the power
tool in unexpected situations.
6. Dress properly. Do not wear loose clothing or jew-
elry. Keep your hair and clothing away from moving
parts. Loose clothes, jewelry or long hair can be caught
in moving parts.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

GENERAL SAFETY RULES
7. 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.
POWER TOOL USE AND CARE
1. 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.
2. 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.
3. Disconnect the plug from the power source and/or
the battery pack 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.
4. 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 us-
ers.
5. Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool’s opera-
tion. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained
power tools.
6. Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
7. Use the power tool, accessories and tool bits, etc.
in accordance with these instructions, taking into ac-
count the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situa-
tion.
8. Use clamps to secure your workpiece to a stable
surface. Holding a workpiece by hand or using your
body to support it may lead to loss of control.
9. KEEP GUARDS IN PLACE and in working order.
SERVICE
1. Have your power tool serviced by a qualified repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is main-
tained.
CALIFORNIA PROPOSITION 65 WARNING

nia to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling. Some examples of
these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other
masonry products.
• 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 ex-
posure to these chemicals, work in a well-ventilated area
with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool”
in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may
result in electric shock, fire and/or serious injury.

BRAD NAILER & STAPLER SAFETY WARNINGS
BRAD NAILER & STAPLER SAFETY
1. THIS TOOL IS DESIGNED for household use only, not
for industrial or professional purposes. Do not force the
tool to do a job for which it was not designed.
2. INSPECT TOOL BEFORE USE. Do not operate if any
portion of the tool, trigger, or safety bracket is damaged,
inoperable, disconnected, or altered. Damaged or
missing parts should be repaired or replaced.
3. GRIP THE TOOL FIRMLY with both hands to maintain
control while still allowing it to recoil away from the work
surface as the fastener is driven.
4. KEEP FACE AND BODY PARTS AWAY from the back
of the tool cap when working in restricted areas. Sudden
recoil can result in impact to the body, especially when
nailing into hard or dense material.
5. DO NOT DISCHARGE fasteners into open air, concrete,
stone, extremely hard woods, knots, or any material too
hard for the fastener to penetrate.
6. DO NOT DRIVE FASTENERS near the edge of your work
material. The workpiece may split, causing the fastener
to ricochet, injuring you or a bystander. Be aware that
the fastener may follow the grain of the wood, causing
it to protrude unexpectedly from the side of the work
material. Drive the fastener perpendicular to the grain to
reduce risk of injury.
7. DO NOT DRIVE FASTENERS onto the heads of other
fasteners. Do not use the tool at too steep of an angle.
Personal injury from strong recoil, jammed fasteners, or
ricochetted nails may result.
8. BE AWARE of material thickness when using the nailer.
A protruding nail may cause injury.
9. WHEN THE TOOL IS BEING UTILIZED AT SPEEDS
ON THE HIGH END of its operating range, fasteners
can be driven completely through thin or very soft work
material. Make sure the speed is set so that fasteners are
set into the material and not pushed completely through.
10. REMOVE FINGER FROM TRIGGER when not driving
fasteners. Never carry the tool with your finger on the
trigger.
11. IF THE FASTENERS ARE JAMMED, turn the tool OFF
and remove the battery from the tool before removing
the jammed fasteners.
12. TURN THE TOOL OFF AND REMOVE THE BATTERY
FROM THE TOOL WHEN NOT IN USE. Remove fasteners
from magazine before leaving the area or passing the
tool to another operator. Do not climb ladders, stairs,
scaffoldings, etc. with the tool ON. Do not carry the
tool when it is ON to another work area. Do not make
adjustments, remove magazine, perform maintenance
or clear jammed fasteners while the tool is ON.
13. DO NOT REMOVE, tamper with, or otherwise cause
the tool, trigger, or safety bracket to become inoperable.
Do not tape or tie the trigger or safety bracket in the ON
position. Do not remove springs from the safety bracket.
Make daily inspections for free movement of the trigger
and safety bracket. Do not alter or modify the tool in any
way.
14. MAINTAIN TOOLS PROPERLY. Always keep tools
clean and in good working order. Follow instructions for
lubricating, changing accessories, and storage.

AMPERAGE
REQUIRED GAUGE FOR EXTENSION CORDS
25 ft. 50 ft. 100 ft. 150 ft.
2A 18 gauge 16 gauge 16 gauge 14 gauge
IMPORTANT: Servicing a double-insulated product requires extreme care and knowledge of the system, and
should be done only by qualified service personnel using identical replacement parts. Always use original factory
replacement parts when servicing.
1. Polarized Plugs. To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse
the plug. If it still does not fit, contact a qualified electrician to install a proper outlet. Do not modify the machine
plug or the extension cord in any way.
2. Ground fault circuit interrupter protection (GFCI) should be provided on the circuit or outlet used for this power
tool to reduce the risk of electric shock.
3. Service and repair. To avoid danger, electrical appliances must only be repaired by a qualified service technician
using original replacement parts.
GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An
undersized cord will cause a drop in line voltage, resulting in loss of power and overheating. The table below shows
the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The
smaller the gauge number, the heavier the cord.
DOUBLE-INSULATED CHARGER
The charger’s electrical system is double-insulated where two systems of insulation are provided. This
eliminates the need for the usual three-wire grounded power cord. Double-insulated tools do not need
to be grounded, nor should a means for grounding be added to the product. All exposed metal parts are
isolated from the internal metal components with protecting insulation.
1. Examine extension cord before use. Make sure your extension cord is properly wired and in good condition.
Always replace a damaged extension cord or have it repaired by a qualified person before using it.
2. Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on
plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord.
Protect your extension cords from sharp objects, excessive heat and damp/wet areas.
3. Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be
protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in
the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running
at a lower voltage will damage the motor.
BATTERY & CHARGER SAFETY WARNINGS
ABOUT THE BATTERY
1. The battery pack has to be charged completely before you use the tool for the first time.
2. For optimum battery performance, avoid low discharge cycles by charging the battery pack frequently.
3. Lithium-ion batteries are subject to a natural aging process. The battery pack must be replaced at the latest when
its capacity falls to just 80% of its capacity when new. Weakened cells in an aged battery pack are no longer capable
of meeting the high power requirements needed for the proper operation of your tool, and therefore pose a safety
risk.
4. Do not throw battery packs into an open fire as this poses a risk of explosion. Do not ignite the battery pack or
expose it to fire.
5. Do not exhaustively discharge batteries. Exhaustive discharge will damage the battery cells. The most common
cause of exhaustive discharge is lengthy storage or non-use of partially discharged batteries. Stop working as soon
as the performance of the battery falls noticeably or the electronic protection system triggers. Place the battery pack
in storage only after it has been fully charged.
6. Protect batteries and the tool from overloads. Overloads will quickly result in overheating and cell damage inside
the battery housing even if this overheating is not apparent externally.
7. Avoid damage and shocks. Immediately replace batteries that have been dropped from a height of more than
one meter or those that have been exposed to violent shocks, even if the housing of the battery pack appears to be
undamaged. The battery cells inside the battery may have suffered serious damage. In such instances, please read
the waste disposal information for proper battery disposal.
8. If the battery pack suffers overloading and overheating, the integrated protective cutoff will switch off the equip-
ment for safety reasons.
9. Use only original battery packs. The use of other batteries poses a fire risk and may result in injuries or an explo-
sion.
ABOUT THE CHARGER
Protect battery charger and cord from damage. Keep the charger and its cord away from heat, oil and sharp edges.
Electrical plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with ground-
ed appliances. Unmodified plugs and matching outlets will reduce the risk of electric shock.
Keep the battery charger, battery pack(s), and the cordless tool out of the reach of children.
Do not use the supplied battery charger to charge other cordless tools.
During periods of heavy use, the battery pack will become warm. Allow the battery pack to cool to room temperature
before inserting it into the charger to recharge.
Do not overcharge batteries. Do not exceed the maximum charging times. These charging times only apply to dis-
charged batteries. Frequent insertion of a charged or partially charged battery pack will result in overcharging and
cell damage. Do not leave battery in the charger for days on end.
Never use or charge a battery if you suspect that it has been more than 12 months since last time they were charged.
There is a high probability that the battery pack has already suffered dangerous damage (exhaustive discharge).
Do not use batteries that have been exposed to heat during the charging process, as the battery cells may have suf-
fered dangerous damage.
Do not use batteries that have suffered curvature or deformation during the charging process or those that exhibit
other atypical symptoms (gassing, hissing, cracking, etc.)
