2 Safety
2.1 General power tool safety warnings
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.
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 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. 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.
Printed: 04.10.2017 | Doc-Nr: PUB / 5377202 / 000 / 01

English 3
▶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 an RCD 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 battery pack, picking up or carrying the tool. Carrying power tools
with your finger on the switch or energising 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 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.
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 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,
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
Printed: 04.10.2017 | Doc-Nr: PUB / 5377202 / 000 / 01

performed. Use of the power tool for operations different from those intended could
result in a hazardous situation.
Battery tool use and care
▶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.
▶Use power tools only with specifically designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
▶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.
▶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.
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.
2.2 Tacker safety warnings
▶Always assume that the tool contains fasteners. Careless handling of the fastening
tool can result in unexpected firing of nails causing personal injury.
▶Do not point the tool towards yourself or anyone nearby. A nail will be ejected by
the tool if it is triggered unexpectedly, possibly leading to 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 fastening tool may be accidentally activated if
it is plugged in.
▶Use caution while removing a jammed fastener. The mechanism may be under
tension and the nail may be forcefully ejected while attempting to free a jam.
▶When fastening electrical cables, make sure the cables are not energized.
Hold the fastening tool only by insulated gripping surfaces. Use only fasteners
designed for electrical cable installations. Check that the fastener has not
damaged the insulation of the electrical cable. A nail that damages the insulation
of electric cables can lead to electric shock and fire hazards.

3.2 Intended use
The product is a hand-held, cordless fastening tool for indoor use. It is designed to drive
specially manufactured fasteners (nails) into concrete, steel, masonry, sand-lime block
and other materials suitable for use of the direct fastening technique. The product is also
designed to fasten electrical cables with clips if the appropriate fasteners are used. Use
only approved fasteners in combination with their corresponding fastener guide (see the
section headed "Technical data").
The fastening tool, battery and fasteners together form a technical entity. This means that
trouble-free fastening with this fastening tool can be ensured only when the Hilti fasteners
and chargers and batteries recommended by Hilti are used. The fastening and application
recommendations made by Hilti apply only when these conditions are observed.
▶The fastening tool is for hand-held use only.
▶Misuse of the fastening tool must be ruled out. Misuse of the fastening tool includes
triggering in single-fastener mode without a nail inserted in the fastener guide, driving
nails into very soft materials (e.g. wood), driving single nails when the tool is set
to magazine operation, and driving nails into materials that are too hard (e.g. high-
strength steel or very hard natural stone).
▶Use only Hilti Liion batteries of the B 22 series with this product.
▶Use only Hilti battery chargers of the C 4/36 series to charge these batteries.
3.3 Safety devices
In magazine mode, the nail detector prevents triggering without a nail loaded, which
could damage the fastening tool.
The contact pressure safety device is intended to prevent the free flighting of nails (i.e.
actuation and driving a nail when the nosepiece is not in contact with the workpiece). In
magazine mode, the fastening tool can be pressed against the surface and triggered only
when a nail is loaded in the tool.
To use the tool in single-fastener mode, you have to press the single-fastener mode
switch before pressing the fastening tool against the working surface.
3.4 Features
The fastening tool has an ergonomic, non-slip, vibration-absorbing grip and a support
leg. The tool is protected from overloading by electronic overload protection and from
overheating by temperature monitoring.
