NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardised
test given in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary asses-
sment of exposure. The declared vibration emission level represents the main applications of the tool. However if
the tool is used for different applications, with different accessories or poorly maintained, the vibration emission
may differ. This may significantly increase the exposure level over the total working period. An estimation of the
level of exposure to vibration should also take into account the times when the tool is switched off or when it is
running but not actually doing the job. This may significantly reduce the exposure level over the total working peri-
od. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the
tool and the accessories, keep the hands warm, organisation of work patterns.

5. Safety instructions
NOTE
The safety rules in section 5.1 contain all general safety rules for
power tools which, in accordance with the applicable standards,
require to be listed in the operating instructions. Accordingly, some
of the rules listed may not be relevant to this tool.
5.1. General Power Tool Safety Warnings
a) WARNING! Read all safety warnings and all instruc-
tions. 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. The term “power tool”
in the warnings refers to your mains-operated (corded) power
tool or battery-operated (cordless) power tool.
5.1.1 Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas
invite accidents.
b) Do not operate power tools in explosive atmospheres, such
as in the presence of flammable liquids, gases or dust. Pow-
er tools create sparks which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a pow-
er tool. Distractions can cause you to lose control.
5.1.2 Electrical safety
a) Power tool plugs must match the outlet. Never modify the
plug in any way. Do not use any adapter plugs with earth-
ed (grounded) power tools. Unmodified plugs and matching
outlets will reduce risk of electric shock.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water
entering a power tool will increase the risk of electric shock.
d) 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 entan-
gled cords increase the risk of electric shock.
e) When operating a power tool outdoors, use an extension
cord suitable for outdoor use. Use of a cord suitable for out-
door use reduces the risk of electric shock.
f) 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.
5.1.3 Personal safety
a) 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.
b) Use personal protective equipment. Always wear eye pro-
tection. Protective equipment such as dust mask, non-skid safe-
ty shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Prevent unintentional starting. Ensure the switch is in the
off-position before connecting to power source and/or bat-
tery 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.
d) 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.
e) Do not overreach. Keep proper footing and balance at all
times. This enables better control of the power tool in unex-
pected situations.
f) 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.
g) If devices are provided for the connection of dust extrac-
tion and collection facilities, ensure these are connected

5.2 Additional safety precautions
5.2.1 Personal safety
a) Hold power tool by insulated gripping surfaces, when
performing an operation where the cutting acces-
sory may contact hidden wiring or its own cord. Cut-
ting accessory contacting a "live" wire may make expo-
sed metal parts of the power tool "live" and could give
the operator an electric shock.
b) Wear ear protectors. Exposure to noise can cause hear-
ing loss.
c) Use auxiliary handle(s), if supplied with the tool. Loss
of control can cause personal injury.
d) Wear respiratory protection when the work causes
dust.
e) Exercise your fingers during pauses between work
to improve the blood circulation in your fingers.
f) Switch the tool on only once it has been brought into
the working position close to the workpiece.
g) To avoid tripping and falling when working, always
lead the sypply cord, extension cord and dust extrac-
tion hose away tho the rear.
h) The insert tool may become hot during use. There
is a risk of burning the hands. Wear protective gloves
when changing insert tools.
i) Dust from material such as paint containing lead,
some wood species, minerals and metal may be harm-
ful. Contact with or inhalation of the dust may cause
allergic reactions and/or respiratory diseases to the
operator or bystanders. Certain kinds of dust are clas-
sified as carcinogenic such as oak and beech dust
especially in conjunction with additives for wood con-
ditioning (chromate, wood preservative). Material
containing asbestos must only be treated by spe-
cialists.
Where the use of a dust extraction device is
possible it shall be used. To achieve a high level of
dust collection, use a suitable vacuum cleaner of
the type recommended by Hilti for wood dust and/or
mineral dust together with this tool. Ensure that the
workplace is well ventilated. The use of a dust mask
of filter class P2 is recommended. Follow national
requirements for the materials you want to work
with.
j) The tool is not intended for use by children, by debil-
itated persons or those who have received no instruc-
tion or training.
k) Children must be instructed not to play with the tool.
5.2.2 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.
Poorly ventilated workplaces may be injurious to the
health due to exposeure to dust.
5.2.3 Electrical safety
a) Before beginning work, check the working area (e.g.
with a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.
External metal parts of the tool may become live if,
for example, an electric cable is damaged inadvertenly.
This presents a serious risk of electric shock.
b) Check the condition of the supply cord and its plug
connections and have it replaced by a qualified elec-
trician if damage is found. Check the condition of
the extension cord and replace it if damage is found.
Do not touch the supply in the event of it suffering
damage while working. Disconnect the supply cord
plug from the socket
. Damaged supply cords and
extension cords present a risk of electric shock.
c) Dirty or dusty electric tools should thus be checked
at a Hilti service center at regular intervals, espe-
cially if used frequently for working on conductive
materials.
Dust (especially dust from conductive
materials) or dampness adhering to the surface of
the tool may, under unfavorable conditions, present
a risk of electric shock.
d) When working outdoors with an electric tool it must
be ensured that the tool is connected to the elec-
tric supply by way of a ground fault circuit breaker
(RCD) with a maximum rating of 30 mA (max. 30
mA tripping current).
Use of a ground fault circuit
breaker reduces the risk of electric shock.
and properly used. Use of dust collection can reduce dust-
related hazards.
5.1.4 Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source and/or the bat-
tery pack from the power tool before making any adjust-
ments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the pow-
er tool accidentally.
d) 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 dan-
gerous in the hands of untrained users.
e) 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.
f) Keep cutting tools sharp and clean. Properly maintained cut-
ting tools with sharp cutting edges are less likely to bind and are
easier to control.
g) Use the power tool, accessories and tool bits etc. in accor-
dance with these instructions, taking into account the work-
ing conditions and the work to be performed. Use of the pow-
er tool for operations different from those intended could result
in a hazardous situation.
5.1.5 Service
a) 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.

er cover as a grip. The blade holder presents a risk of
injury.
7.1 Switching on/off
1. Plug the supply cord into the electric socket.
2. Press the transport lock and then press the control
switch.
7.2 Stroke rate
7.2.1 Adjusting the stroke rate 
The recommended stroke rate can be selected by turn-
ing the stroke rate regulator
When the control switch is pressed the tool will then run
up to the pre-selected speed. The electronic speed con-
trol system maintains an almost constant stroke rate
even under load. The recommended stroke rate settings
and information concerning the correct choice of saw
blade can be found in the product information and in the
corresponding table of applications.
7.2.2 Recommended stroke rates
(1 = low stroke rate, 6 = high stroke rate)
Material to be cut Recommended
stroke rate
Wood 5–6
Wood with embedded nails 5–6
Interior finishing, drywall 3–4
Plastic 3–4
Steel 2–3
Non-ferrous metals 2–3
Aluminum 2–3
Stainless steel 1
The above settings are recommendations intended to
ensure optimum cutting performance. These also apply
when the pipe cutting adapter (accessory) is used. The
optimum setting may differ from these recommenda-
tions depending on the saw blade used, the electric sup-
ply voltage and on how the tool is used. Setting the wrong
stroke rate may cause the saw blade to wear more quickly
and could damage the tool.
7.3 Orbital action 
Use of the orbital action can increase cutting perfor-
mance in certain materials such as wood or wood mate-
rials. The orbital action can be switched on or off by
moving the orbital action selector switch as far as it will
go in each position. Move the switch only when the motor
has stopped.

7.4 Plunge sawing 
The plunge sawing technique should be used only on
soft materials and when the orbital action is switched
off. A little practice is required in order to be able to
plunge the blade into the material while the tool is run-
ning and thus make cut-outs without first drilling a hole.
Plunge sawing is possible only with short saw blades.
Plunge cuts may be started with the tool in one of two
different positions:
– in the normal position
– or in the reversed position
1. Hold the tool with the front edge of the contact shoe
against the workpiece.
2. Press the transport lock and then press the control
switch.
3. Press the tool firmly against the workpiece and begin
the plunge movement by reducing the angle of the
tool (contact shoe) to the workpiece. It is important
to ensure that the tool is running before the blade is
brought into contact with the workpiece. The tool may
otherwise stall.
4. Once the blade has passed through the workpiece,
bring the tool into the normal working position (the
entire surface of the shoe in contact) and then con-
tinue sawing along the line.

8. Care and maintenance
Unplug the supply cord from the mains socket.
8.1 Care of blades
Clean off dirt and dust deposits and protect your blades
from corrosion by wiping them from time to time with
an oil-soaked rag.
8.2 Care of the tool
●Keep the blade clamp clean.
●The tool was lubricated adequately when it was man-
ufactured. After long periods of heavy use it is rec-
ommended that the tool is inspected at a Hilti work-
shop. This will increase the life expectancy of the tool
and avoid unnecessary repair costs.
●Repairs to the electrical section of the tool may be car-
ried out only by a trained electrical specialist.
CAUTION
Keep the power tool, especially its grip surfaces, clean
and free from oil and grease. Do not use cleaning agents
which contain silicone.
The outer casing of the tool is made from impactresis-
tant plastic. Sections of the grip are made from a syn-
thetic rubber material. Never operate the tool when the
ventilation slots are blocked. Clean the ventilation slots
carefully using a dry brush. Do not permit foreign objects
to enter the interior of the tool. Clean the outside of the
tool at regular intervals with a slightly damp cloth. Do not
use a spray, steam pressure cleaning equipment or run-
ning water for cleaning. This may negatively affect the
electrical safety of the tool.
8.3 Maintenance
Check all external parts of the tool for damage at regular
intervals and check that all controls operate faultlessly.
Do not operate the tool if parts are damaged or when the
controls do not function faultlessly. If necessary, your
electric tool should be repaired at a Hilti repair center.
Repairs to the electrical section of the tool may be car-
ried out only by trained electrical specialists.
8.4 Checks after care and maintenance
After care and maintenance, check that the hand guard
and contact shoe are fitted and that they function fault-
lessly.
