GENERAL SAFETY WARNINGS
WARNING:
Before using this tool or any of its accessories, read this manual and follow all Safety
Rules and Operating Instructions. The important precautions, safeguards and
instructions appearing in this manual are not meant to cover all possible situations.
It must be understood that common sense and caution are factors which cannot be
built into the product.
SYMBOL MEANING
ALWAYS WEAR EYE PROTECTION THAT CONFORMS WITH CSA
Z94.3 or ANSI SAFETY STANDARD Z87.1
FLYING DEBRIS can cause permanent eye damage. Prescription
eyeglasses ARE NOT a replacement for proper eye protection.
Non-compliant eyewear can cause serious injury if broken during
the operation of a power tool.
Use hearing protection, particularly during extended periods of
operation of the tool, or if the operation is noisy.
WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
Dust that is created by power sanding, sawing, grinding,drilling, and
other construction activities may contain chemicals that are known to
cause cancer, birth defects, or other genetic abnormalities.
These chemicals include:
• Lead from lead-based paints
• Crystalline silica from bricks, cement, and other masonry products
• Arsenic and chromium from chemically treated lumber
The level of risk from exposure to these chemicals varies, according to
how often this type of work is performed. In order to reduce exposure
to these chemicals, work in a well-ventilated area, and use approved
safety equipment, such as a dust mask that is specifically designed to
filter out microscopic particles.
ELECTRICAL SAFETY
WARNING:
Only use the battery and charger recommended for this product to charge the 20V
Li-ion batteries used for this tool.
Using other batteries may damage the charger and possibly cause damage to the
tool or cause serious injury.
WARNING:
Read all safety warnings and instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.

WORK AREA SAFETY
Keep work area clean and well lit. Cluttered or 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 children and bystanders away while operating the 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. Unmodified
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 carrying, 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 residual
current device (RCD) protected supply. Use of a ground fault circuit interrupter
(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 influence
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 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 finger 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.

5
Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing, and gloves away from moving parts. Loose clothes, jewellery 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 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.
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 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.
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. Check for misalignment or binding of moving parts,
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.
result in a hazardous situation.
Hold power tool by insulated gripping surfaces when performing an operation
where the cutting tool may contact hidden wiring or its own cord. Contact with a
"live" wire will make exposed metal parts of the tool "live" and shock the operator.
Use clamps or another practical way to secure and support the workpiece to a
stable platform. Holding the work by hand or against your body leaves it unstable
and may lead to loss of control.
SERVICE
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 maintained.

BATTERY TOOL USE AND CARE
a) Recharge only with the charger specified by the manufacturer. A charger that
is suitable for one type of battery pack may create a risk of fire when used with
another battery pack.
b) Use power tools only with specifically designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
c) 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 fire.
d) Under abusive conditions, liquid may be ejected from the battery: avoid
contact. If contact accidentally occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the battery may cause
irritation or burns.

SPECIFIC SAFETY RULES
WARNING:
Know your nailer/stapler. Do not use the nailer/stapler until you have read and
understand this Instruction Manual. Learn the tool’s applications and limita-
tions, 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.
Always wear eye protection. Any power tool can throw foreign objects
into your eyes and cause permanent eye damage. ALWAYS wear safety
goggles (not glasses) that comply with ANSI safety standard Z87.1.
Everyday glasses have only impact resistant lenses. They ARE NOT
safety glasses.
WARNING:
Glasses or goggles not in compliance with ANSI Z87.1 could cause serious
injury when they break.
Always wear safety goggles, hearing protection and a dust mask. Use only in
well-ventilated areas. Using personal safety devices and working in a safe environ-
ment reduces the risk of injury.
Hold the tool by insulated gripping surfaces when performing an operation where
the nailer/stapler may contact hidden wiring or its own cord. Contact with a "live"
wire will make exposed metal parts of the tool "live" and shock the operator.
Always make sure the work surface is free of nails and other foreign objects. Nailing/
stapling into a nail can cause the tool to jump and damage to you and/or the tool.
Never hold the workpiece in one hand and the tool in the other hand when nailing or
stapling.
Never place your hands near or below the nailing/stapling surface. Clamping the
material and guiding the tool with both hands is much safer.
Never lay the workpiece on hard surfaces like concrete, stone, etc. The protruding
nails or staples may cause the tool to jump.
DANGER: Always remove the battery when changing the nails or staples and
when making adjustments.
Always assume that the tool contains fasteners. Careless handling of the nailer can
result in unexpected firing of fasteners and personal injury.
Do not point the tool towards yourself or any one nearby. Unexpected triggering will
discharge the fastener causing an injury.
Do not actuate the tool unless the tool is placed firmly against the workpiece. If the
tool is not in contact 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 activated if it is connected to a
power supply.
Use caution while removing a jammed fastener. The mechanism may be under
