NOTE
The vibration emission level given in this information sheet has been measured in accordance with a standardized 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 is 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: maintaining the tool and the accessories,
keeping hands warm, organization 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
en
5
Printed: 12.03.2014 | Doc-Nr: PUB / 5075277 / 000 / 03

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.
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 servicedby a qualified repair
person using only identical replacement parts.
This will ensure that the safety of the power tool is
maintained.
5.2 Safety instructions for all saws
5.2.1 Cutting procedures
a) DANGER
Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or
motor housing. If both hands are holding the saw,
they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the work-
piece.
c) Adjust the cutting depth to the thickness of the
workpiece. Less than a full tooth of the blade teeth
should be visible below the workpiece.
d) Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable plat-
form. It is important to support the work properly to
minimize body exposure, blade binding, or loss of
control.
e) Hold the power tool by insulated gripping surfaces
only, when performing an operation where the
cutting tool may contact hidden wiring. Contact
with a “live” wire will also make exposed metal parts
of the power tool “live” and could give the operator
an electric shock.
f) When ripping always use a rip fence or straight
edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
g) Always use blades with correct size and shape
(diamond versus round) of arbour holes. Blades
that do not match the mounting hardware of the saw
will run eccentrically, causing loss of control.
h) Never use damaged or incorrect blade washers
or bolt. The blade washers and bolt were specially
designed for your saw, for optimum performance and
safety of operation.
5.2.2 Further safety instructions for all saws
Kickback causes and related warnings
kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw to lift
up and out of the workpiece toward the operator;
when the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;
if the blade becomes twisted or misaligned in the cut, the
teeth at the back edge of the blade can dig into the top
surface of the wood causing the blade to climb out of the
kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below.
a) Maintain a firm grip with both hands on the saw
and position your arms to resist kickback forces.
Position your body to either side of the blade, but
not in line with the blade. Kickback could cause the
saw to jump backwards, but kickback forces can be
controlled by the operator, if proper precautions are
taken.
b) When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the blade
comes to a complete stop. Never attempt to re-
move the saw from the work or pull the saw back-
ward while the blade is in motion or kickback
en
6
Printed: 12.03.2014 | Doc-Nr: PUB / 5075277 / 000 / 03

may occur. Investigate and take corrective actions
to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw
blade is binding, it may walk up or kickback from the
workpiece as the saw is restarted.
d) Support large panels to minimise the risk of blade
pinching and kickback. Large panels tend to sag
under their own weight. Supports must be placed
under the panel on both sides, near the line of cut
and near the edge of the panel.
e) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If
blade adjustment shifts while cutting, it may cause
binding and kickback.
g) Use extra caution when sawing into existing walls
or other blind areas. The protruding blade may cut
objects that can cause kickback.
5.2.3 Safety instructions for circular saws with
outer pendulum guard
Lower guard function
a) Check lower guard for proper closing before each
use. Do not operate the saw if lower guard does
not move freely and close instantly. Never clamp
or tie the lower guard into the open position. If saw
is accidentally dropped, lower guard may be bent.
Raise the lower guard with the retracting handle and
make sure it moves freely and does not touch the
blade or any other part, in all angles and depths of
cut.
b) Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
c) Lower guard may be retracted manually only for
special cuts such as “plunge cuts” and “com-
pound cuts.” Raise lower guard by retracting
handle and as soon as blade enters the mater-
ial, the lower guard must be released. For all other
sawing, the lower guard should operate automatic-
ally.
d) Always observe that the lower guard is covering
the blade before placing saw down on bench or
floor. An unprotected, coasting blade will cause the
saw to walk backwards, cutting whatever is in its
path.Beawareofthetimeittakesforthebladeto
stop after switch is released.
5.3 Additional safety instructions
5.3.1 Personal safety
a) Wear ear protectors. Exposure to noise can cause
hearing loss.
b) Always hold the power tool securely with both

l) Do not touch the clamping flange or the clamping
screw while the power tool is running.
m) Never press the drive spindle lock button while
the saw blade is rotating.
n) Never direct the power tool toward persons.
o) Adjust the pressure applied to the saw blade and
the material being cut so that the blade does not
stall, possibly causing the power tool to kick back.
p) Avoid overheating the tips of the saw blade teeth.
q) Metal cuttings are sharp and present a risk of injury.
Keep your clothing closed so that metal cuttings
cannot find their way into your gloves, shoes or
other parts of your clothing.
r) Pay attention to the direction in which the metal chips
fly when sawing. Thechipsarehotandmaycause
fires or lead to burning and cutting injuries.
s) Children must be instructed not to play with the
power tool.
t) The power tool is not intended for use by children,
by debilitated persons or those who have received
no instruction or training.
u) Dust from materials such as paint or coatings
containing lead, mineral materials and metals may
present a health hazard. Contact with or inhalation
of the dust may cause allergic reactions and/or
respiratory diseases among operators or bystanders.
Certain dusts are considered to be carcinogenic
(cancer-causing), especially in conjunction with
other substances (chromate). Material containing
asbestosmaybeworkedononlybyspecialists.
Ensure that the workplace is well ventilated.

5.3.2 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.
c) Take care to ensure that metal cuttings do not
find their way into the tool or battery.
d) Empty the chip collector and clean the power
tool before putting it away in the toolbox or other
container for storage or transport. Metal chips may
otherwise fall out of the collector and find their way
into the power tool, battery or charger, presenting a
risk of damage or malfunction.
5.3.3 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.
5.3.4 Battery 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. This presents a risk of fire, explosion or injury
through contact with caustic substances.
d) Use only batteries that are approved for use with
the applicable tool or appliance. Use of unap-
proved batteries or use of the batteries for areas of
application for which they are not approved 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) 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.
5.3.5 Work area
a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated. Ex-
posure to dust at a poorly ventilated workplace may
result in damage to the health.
5.3.6 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.
5.3.7 Safety precautions
Do not switch the power tool on if the saw blade,
the blade guard or the pivoting guard are not fitted
correctly.

CAUTION
Empty the chip collector and clean the power tool
before putting it away in the toolbox or other container
for storage or transport. Metal chips may otherwise fall
out of the collector and find their way into the power
tool, battery or charger, presenting a risk of damage or
malfunction.
Pull the battery out of the locked position (working pos-
ition) and move it into the first click-stop position (trans-
port position).
If you disconnect a battery from the power tool for trans-
port or storage, make sure that the battery contacts are
not short-circuited. Remove loose metal items such as
screws, nails, clamps, loose screwdriving bits, wires or
metal cuttings and chips from the toolbox or transport
container, or prevent these items from coming into con-
tact with the battery.
Observe national and international transport regulations
when shipping batteries (transportation by road, rail, sea
or air).
7Operation
NOTE
If the blade has jammed, the tool will not restart by itself
after pressure on it has been released. The switch-on
interlock and the on/off button must be pressed again to
restart.
NOTE
The chip collector must always be fitted when the tool is
in use.
CAUTION
Wear protective gloves. The cutting edges of the saw
blade and cut edges of the workpiece are sharp. These
sharp edges present a risk of injury.
CAUTION
Wear protective glasses and a dust mask. The sawing
operation swirls up dust and chips into the air. The dust
and chips may be harmful to the eyes and respiratory
system.
CAUTION
Wear ear protectors. The power tool and the sawing
operation generate noise. Exposure to noise can cause
loss of hearing.
CAUTION
Secure the workpiece. Use clamps or a vice to secure
the workpiece. This will help to prevent vibration.

8 Care and maintenance
CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional start-
ing.
8.1Careofinserttools
Clean off dirt and dust deposits adhering to the insert
tools and protect them from corrosion by wiping the
insert tools from time to time with an oil-soaked rag.
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 ingress of moisture.
Charge the battery fully before using it for the first time.
In order to achieve maximum battery life, stop dischar-
ging the battery as soon as a significant drop in battery
performance is noticed.
NOTE
If use continues, further battery discharge will be stopped
automatically before the battery cells suffer damage.
Charge the battery using an approved charger from Hilti
designed 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. Storing the battery in
places subject to high ambient temperatures (e.g. at
a window) 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 still possible to work with this battery. You should,
however, soon replace the battery with a new one.
8.4 Cleaning the safety devices
1. Remove the saw blade before cleaning the safety
devices.
2. Clean the safety devices carefully with a dry brush.
3. Useasuitabletooltoremovedepositsorwood
chips from the inside surfaces of the safety devices.
4. Fit the saw blade.
8.5 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.
Have the power tool repaired by Hilti Service.
8.6 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.
