NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardised test
giveninEN60745andmaybeusedtocompareonetoolwithanother.Itmaybeused for a preliminary assessment
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 period. 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, must 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 instructions. Fail-
ure 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.
5.1.1Workareasafety
a) Keep work area clean and well lit. Cluttered or dark
areas invite accidents.
b) 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 ignite the dust or fumes.
c) Keep children and bystanders away while operat-
ing a power 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 ad-
apter plugs with earthed (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 condi-
tions. 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 entangled cords increase
theriskofelectricshock.
e) 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.
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 protection. Protective equipment such as dust
mask, non-skid safety 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 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.
d) Remove any adjusting key or wrench before turn-
ing the power tool on. A wrench or a key left at-
tached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and bal-
ance at all times. This enables better control of the
power tool in unexpected 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
extraction and collection facilities, ensure these
are connected 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 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.
d) Store idle power tools out of the reach of chil-
dren 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.
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.
en
18
Printed: 08.07.2013 | Doc-Nr: PUB / 5071383 / 000 / 04

f) 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.
g) 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 opera-
tions different from those intended could result in a
hazardous situation.
5.1.5 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 acci-
dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquid ejec-
ted from the battery may cause irritation or burns.
5.1.6 Service
a) Have your power tool serviced bya qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
5.2 Additional safety instructions
5.2.1 Personal safety
a) Hold power tool by insulated gripping surfaces,
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting ac-
cessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give
the operator an electric shock.
b) Wear ear protectors. Exposure to noise can cause
hearing loss.
c) Use auxiliary handles, if supplied with the tool.
Loss of control can cause personal injury.
d) Always hold the power tool securely with both
hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.
e) Breathing protection must be worn if the power
tool is used without a dust removal system for
work that creates dust.
f) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
g) Operate the power tool only as intended and when
it is in faultless condition.
h) Wear protective gloves when changing insert
tools as the insert tools get hot during use.
i) Switch the power tool on only after bringing it into
the working position.
j) Avoid unintentional starting. Never carry the
power tool with your finger on the on/off switch.
Remove the battery from the power tool during
work breaks, before carrying out maintenance,
before changing cutting tools and before
transporting the power tool.
k) Children must be instructed not to play with the
power tool.
l) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
m) Dust from material such as paint containing lead,
some wood species, minerals and metal may be
harmful. 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 classified as carcinogenic such as oak and beech
dust especially in conjunction with additives for wood
conditioning (chromate, wood preservative). Material
containing asbestos must only be treated by special-
ists. 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. Fol-
low national requirements for the materials you
want to work with.
5.2.2 Power tool use and care
a) Secure the workpiece. Use clamps or a vice to
secure the workpiece. The workpiece is thus held
more securely than by hand and both hands remain
free to operate the power tool.
b) Check that the insert tools used are compatible
with the chuck system and that they are secured
in the chuck correctly.
5.2.3 Special safety instructions for reciprocating
saws
a) Always guide the power tool away from your body
when working with it.
b) Neverpositionyourhandsaheadoforonthesaw
blade.
c) Never cut into unknown materials and keep the
line of cut above and below the workpiece free of
obstacles. If the saw blade strikes an object it may
cause the power tool to kick back.
d) Apply moderate pressure and set the power tool
to a suitable stroke rate when using the pipe-
cutting adapter (accessory), especially when cut-
ting large-diameter pipes. This will help to prevent
the power tool overheating.
e) The power tool must be pressed against the work-
piece until the contact shoe makes firm contact.
This helps ensure maximum safety and good per-
formance.
f) Wear suitable protective clothing to protect you
from hot cuttings.
en

Printed: 08.07.2013 | Doc-Nr: PUB / 5071383 / 000 / 04

g) Never use the power tool without the hand guard
fitted.
h) Before beginning the work, check the hazard clas-
sification of the dust that will be produced. Use
an industrial vacuum cleaner with an officially
approved protection classification in compliance
with locally applicable dust protection regula-
tions.
i) WARNING!When cutting through pipes, e.g. when
carrying out demolition or installation work, check
to ensure that the pipes no longer contain li-
quids and empty them if necessary. When cutting
through pipes, hold the power tool above the level
of the pipe you are cutting through. The power tool
incorporates no protective measures to prevent in-
gress of water or dampness. Liquids running out of
pipes may cause a short circuit in the power tool.
j) Do not use the power tool to cut bricks, concrete,
cellular concrete, natural stone or tiles.
k) Do not attempt to cut material thicker than the
specified max. thickness for which the saw is
designed and do not use unsuitable saw blades
(reciprocating saw blades of the wrong size or not
equipped with a ¹⁄₂" connection end).
5.2.4 Battery tool use and care
a) Observe the special instructions applicable to the
transport, storage and use of Li-ion batteries.
b) Do not expose batteries to high temperatures or
fire. This presents a risk of explosion.
c) Do not disassemble, squash or incinerate batter-
ies and do not subject them to temperatures over
80°C. A risk of fire, explosion or injury through con-
tact with caustic substances may otherwise result.
d) Do not use batteries other than those approved
for use with the applicable power tool or appli-
ance. Use of other batteries or use of the battery for
purposes for which it is not intended presents a risk
of fire and explosion.
e) Do not charge or continue to use damaged bat-
teries (e.g. batteries with cracks, broken parts,
bent or pushed-in and/or pulled-out contacts).
f) Use only the Hilti chargers listed under “Ac-
cessories”.
g) Ensure that the outer surfaces of the battery are
clean and dry before inserting it in the corres-
ponding charger. Read the operating instructions
for the charger for further information about the
charging procedure.
h) If the battery gets too hot to touch, this may indicate
that it is faulty. Place the tool in a location where
it can be kept under observation, well away from
flammable materials, and allow it to cool down.
Contact Hilti Service after the battery has been
allowedtocool.
5.2.5 Electrical safety
Before beginning work, check the working area (e.g.
using a metal detector) to ensure that no concealed
electric cables or gas and water pipes are present.
External metal parts of the power tool may become
live, for example, when an electric cable is damaged
accidentally. This presents a serious risk of electric shock.
5.2.6 Work area safety
Ensure that the workplace is well ventilated. Exposure
to dust at a poorly ventilated workplace may result in
damage to the health.
5.2.7 Personal protective equipment
The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec-
tion, protective gloves and breathing protection while
the tool is in use.

7.4 Adjusting the stroke rate 
NOTE
The recommended stroke rate settings and information
about the correct choice of saw blade can be found in the
product information and in the corresponding application
table.
The recommended stroke rate can be preset by turning
thestrokerateregulator.
See section: 2.4 Stroke rate setting
Press the control switch.
The power tool will then run at the preselected stroke
rate.
7.4.1 Selecting the stroke rate
1 = low stroke rate, 6 = high stroke rate
NOTE
The settings listed are recommended settings for op-
timum cutting performance. They may vary depending
on the type of saw blade used. Setting the wrong stroke
rate may result in rapid saw blade wear.
See section: 2.4 Stroke rate setting
7.5 Plunge cutting 
WARNING
Apply the appropriate safety measures at the rear of
the workpiece when plunge sawing. Only use suitable
saw blades, which are as short as possible.

Use the plunge cutting technique only on soft materials.
It takes a little practice to start the cut, without previously
drilling a starting hole, by plunging the blade into the
surface while the power tool is running. This is possible
only with short saw blades. For plunge cutting, the power
tool may be used either in the normal position or in the
reversed position.
1. Bring the forward edge of the contact shoe into
contact with the surface of the material to be cut.
2. Press the transport lock and then press the control
switch.
3. Press the forward edge of the contact shoe against
the surface and begin the plunge action by slowly
increasing the angle of attack. To prevent stalling, it
is important that the power tool is running before the
saw blade is brought into contact with the surface.
4. Once the saw blade has penetrated right through
the material, bring the power tool into the normal
working position (contact shoe flush with the work-
piece) and then continue sawing along the cutting
line.
8 Care and maintenance
CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional start-
ing.
8.1 Care and maintenance
Keep the blades clean, especially their connection ends,
in order to ensure trouble-free operation of the blade
holder.
Keep the blade holder clean.
The power tool has been adequately lubricated during
assembly. After a long period of heavy use it is recom-
mended that the power tool is inspected by Hilti. This
will help to extend the life of the power tool and avoid
unnecessary repair costs.
8.2 Care of the power tool
CAUTION
Keep the power tool, especially its grip surfaces,
clean and free from oil and grease. Do not use clean-
ing agents which contain silicone.
The outer casing of the power tool is made from impact-
resistant plastic. Sections of the grip are made from a
synthetic rubber material.
Never operate the power 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 power tool. Clean the outside of the power
tool at regular intervals with a slightly damp cloth. Do
not use a spray, steam pressure cleaning equipment or
running water for cleaning. This may negatively affect the
electrical safety of the power tool.
8.3 Care of the Li-ion battery
Avoid entrance of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop discharging
the battery as soon as a significant drop in performance
is noticed.
NOTE
If use of the power tool continues, further battery dis-
charge will be stopped automatically before the battery
cells suffer damage.
Charge the battery with the Hilti charger approved for use
with Li-ion batteries.
NOTE
- A conditioning charge (as is required with NiCd or
NiMH batteries) is not necessary.
- Interruption of the charging procedure has no negative
effect on battery life.
- Charging can be started at any time with no negative
effect on battery life. There is no memory effect (as
with NiCd or NiMH batteries).
- For best results, batteries should be stored fully
charged in a cool dry place. Avoid charging the battery
in places subject to high ambient temperatures (e.g. at
a window) as this has an adverse effect on battery life
and increases the rate of self-discharge.
- If the battery no longer reaches full charge, it may
have lost capacity due to aging or overstressing. It
is possible to continue working with a battery in this
condition but it should be replaced in good time.
8.4 Maintenance
WARNING
Repairs to the electrical section of the power tool may
be carried out only by trained electrical specialists.
Check all external parts of the power tool for damage
at regular intervals and check that all controls operate
faultlessly. Do not operate the power tool if parts are
damaged or when the controls do not function faultlessly.
If necessary, the power tool should be repaired by Hilti
Service.
8.5 Checking the power tool after care and
maintenance
After carrying out care and maintenance work on the
power tool, check that all protective and safety devices
are fitted and that they function faultlessly.

9 Troubleshooting
Fault Possible cause Remedy
The power tool doesn’t start. The control switch is defective. Have it checked by a trained electrical
specialist and replaced if necessary.
The battery is discharged or fitted
incorrectly. The battery must be heard to engage with a double click or, respectively,
needs to be charged.
The power tool doesn’t achieve
full power. The stroke rate is set too low. Adjust the stroke rate regulator to a setting recommended for the material
to be cut.
The control switch is not pressed
fully. Press the control switch as far as it will go.
The battery is discharged. Change the battery and recharge the
discharged battery.
The saw blade can’t be re-
moved from the blade holder. The locking sleeve is not turned as far
as it will go. Turn the locking sleeve as far as it will go and remove the saw blade.
10 Disposal
CAUTION
Improper disposal of the equipment may have serious consequences: the burning of plastic components generates
toxic fumes which may present a health hazard. Batteries may explode if damaged or exposed to very high
temperatures, causing poisoning, burns, acid burns or environmental pollution. Careless disposal may permit
unauthorized and improper use of the equipment. This may result in serious personal injury, injury to third parties and
pollution of the environment.
CAUTION
Dispose of defective batteries without delay. Keep them out of reach of children. Do not attempt to open or dismantle
batteries and do not dispose of them by incineration.
CAUTION
Dispose of the batteries in accordance with national regulations or return them to Hilti.
Most of the materials from which Hilti power tools or appliances are manufactured can be recycled. The materials
must be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for
taking back your old power tools or appliances for recycling. Please ask your Hilti customer service department or
Hilti representative for further information.
For EC countries only
Disposal of electric tools together with household waste is not permissible.
In observance of the European Directive on waste electrical and electronic equipment and its imple-
mentation in accordance with national law, electrical appliances that have reached the end of their life
must be collected separately and returned to an environmentally compatible recycling facility.
