2.6 Deep discharge protection

To extend the life of the battery and the motor, the electronic control system is designed to audibly reduce blade
drive speed when excessive pressure is applied, up to the point at which the blade stalls completely when pressure is
maintained causing activation of the power cut-out.

CAUTION

So long as the on/off switch remains depressed, the power tool runs up to speed again when the pressure applied to
it is released, just like a mains-powered tool.

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 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.

The term “power tool” in the warnings refers to
your mains-operated (corded) power tool or battery­operated (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 adapter
plugs with earthed (grounded) power tools. Un-

modified 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 at­tached 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

5

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

en

be performed. Use of the power tool for opera­tions 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 acci­dentally occurs, flush with water. If liquid contacts
eyes, additionally seek medical help. Liquidejected

from the battery may cause irritation or burns.

5.1.6 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.

5.2 Cutting procedures

a)

b) Do not reach underneath the workpiece. The guard

c) Adjust the cutting depth to the thickness of the

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.

5.3 Further safety instructions for all saws

Causes and Operator Prevention of Kickback:

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 re­move the saw from the work or pull the saw back­ward while the blade is in motion or kickback
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 making a “plunge cut”

into existing walls or other blind areas. The pro­truding blade may cut objects that can cause kick­back.

5.4 Safety instructions for Circular saw with
pendulum guard

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 should be retracted manually only

for special cuts such as “plunge cuts” and “com­pound cuts.” Raise lower guard by retracting han­dle and as soon as blade enters the material, the
lower guard must be released. For all other sawing,

the lower guard should operate automatically.

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.

5.5 Additional safety instructions

5.5.1 Personal safety

a) Wear ear protectors. Exposure to noise can cause

hearing loss.

b) Always hold the power tool securely with both

hands on the grips provided. Keep the grips dry,
clean and free from oil and grease.

c) Breathing protection must be worn if the power

tool is used without a dust removal system for
work that creates dust.

d) Do not operate the power tool without the protec-

tive devices that belong to it.

e) Operate the power tool only as intended and when

it is in faultless condition.

f) Improve the blood circulation in your fingers by

relaxing your hands and exercising your fingers
during breaks between working.

g) Switch the power tool on only after bringing it into

position at the workpiece.

h) Remove the battery before storing or transporting

the power tool.

i) Always guide the power tool away from your body

when working with it.

j) Do not work with the power tool overhead.
k) Do not attempt to brake the speed of the saw

bladebypressingittotheside.

l) Do not touch the clamping flange or the clamping

screw while the power tool is running.

m) The kerf must be free of obstructions. Do not saw

into screws and nails etc.

n) Never press the drive spindle lockbutton while the

saw blade is rotating.

o) Never direct the power tool toward persons.
p) Adjust the pressure applied to the saw blade and

the material being cut so that the blade doesn’t
stall, possibly causing the power tool to kick back.

q) Children must be instructed not to play with the

power tool.

r) The power tool is not intended for use by children,

by debilitated persons or those who have received
no instruction or training.

s) WARNING: Some dust created by grinding, sand-

ing, cutting and drilling contains chemicals known
to cause cancer, birth defects, infertility or other
reproductive harm; or serious and permanent res­piratory or other injury. Some examples of these

chemicals are: lead from lead-based paints, crys­talline silica from bricks, concrete and other masonry
products and natural stone, arsenic and chromium
from chemically-treated lumber. Your risk from these
exposures varies, depending on how often you do
this type of work. To reduce exposure to these

chemicals, the operator and bystanders should
work in a well-ventilated area, work with ap­proved safety equipment, such as respiratory pro­tection appropriate for the type of dust generated,
and designed to filter out microscopic particles
and direct dust away from the face and body.
Avoid prolonged contact with dust. Wear protec­tive clothing and wash exposed areas with soap
and water. Allowing dust to get into your mouth,

eyes, or to remain on your skin may promote absorp­tion of harmful chemicals.

5.5.2 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.

5.5.3 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.

5.5.4 Battery use and care

a) Observe the special instructions applicable to the

transport, storage and use of Li-ion batteries.

en

7

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

en

for use with the applicable power tool or appli­ance. 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) 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
allowed to cool.

5.5.5 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.

5.5.6 Personal protective equipment

The user and any other persons in the vicinity must
wear suitable eye protection, a hard hat, ear protec­tion, protective gloves and breathing protection while
the tool is in use.

5.5.7 Safety precautions

Do not switch the power tool on if the saw blade,
the blade guard or the pivoting guard are not fitted
correctly.

the desired cutting depth by closing the clamping
lever.

7.3 Adjusting the cutting angle 5

The power tool can be set to any angle between 0 and
45º for bevel cuts. Angles of up to 50° can be set after
lifting the angle extender.

1. Pull the battery out of the power tool.

2. Release the cutting angle adjustment clamping
lever.

3. Pivot the power tool into the desired position or,
respectively, lift the angle extender to allow angles
up to 50° to be set.

4. Tighten the cutting angle adjustment clamping lever.

7.4 Sawing along a line

There is a cutting line indicator for straight cuts or bevel
cuts (0° and 45°) at the front section of the base plate of
the power tool. This permits precise cuts to be made at
the selected cutting angle. The edge of the line indicator
corresponds to the inside of the saw blade. The viewing
window provides a better view of the cutting line and thus
ensures a better cut. Additional cutting line indicators are
located at the front opening for the saw blade and at the
end of the base plate.

1. Secure the workpiece so that it cannot move.

2. Position the workpiece so that the saw blade is free
to move under the workpiece.

3. Check to ensure that the switch on the power tool
is in the off-position.

4. Fit the battery into the power tool.

5. Place the power tool with the base plate on the
workpiece in such a way that the blade still has no
contact with the workpiece.

6. Switch the power tool on by pressing the switch-on
interlock and then pressing the on/off switch while
the switch-on interlock is depressed.

7. Guide the power tool along the cutting line on the
workpiece at a suitable speed.

7.5 Sawing using the parallel guide (accessory)

Use of the two-arm parallel guide allows precise cuts to
be made along the edge of the workpiece or, respectively,
strips of even width to be cut.
The parallel guide can be fitted on either side of the base
plate.

7.6 Fitting / adjusting the parallel guide 6

1. Pull the battery out of the power tool.

2. Slacken the clamping screw on the base plate.

3. Slide both arms of the parallel guide under the
clamping screw.

7.7 Using the saw on the guide rail 7

7.7.1 Longitudinal cuts at 0 °

Place the saw on the guide rail so that the rib fits into the
grooveinthebaseplate.

7.7.2 Longitudinal cuts at up to 50 °

Guide the saw so that the outer edge of the base plate
runs along the rib on the guide rail. The saw blade will
otherwise come into contact with the guide rail.

7.7.3 Cuts at an angle across the surface of the
workpiece

NOTE

The cutting angle indicated is the angle of deviation from
a straight, right-angled cut.

1. Position the guide rail with the zero mark at the edge
of the workpiece and then pivot the rail until the
desired angle shown on the angle scale is opposite
the zero mark.

2. Use the two screw clamps to secure the guide rail.

7.8 Trimming to size

1. Secure the guide rail from below with two screw
clamps.
NOTE The saw must be placed on the guide rail
behind the workpiece.

2. CAUTIONTakecaretoensurethatthesawblade

is not in contact with the workpiece.

Position the saw on the guide rail a short distance
from the starting point of the cut.

3. Switch the power tool on.

4. Push the saw steadily across the workpiece.
The pendulum guard opens as it contacts the ac­tuating edge at the side of the guide rail and sub­sequently closes at the end of the rail as the cut is
completed.

8 Care and maintenance

CAUTION
Before beginning cleaning, remove the battery from
the power tool in order to prevent unintentional start­ing.

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 clean­ing agents which contain silicone.

The outer casing of the power tool is made from impact­resistant 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.

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 dis­charge 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.

8.3 Care of the NiCd battery

Avoid entrance of moisture.
Keep the electrical contacts free from dust, oil and
grease. If necessary, use a clean cloth to clean the con­tact surfaces. The battery must be recharged as soon as
the power tool’s performance drops noticeably or when
the deep discharge prevention system becomes active.

NOTE

Please refer to the operating instructions for the charger
for further information about charging the battery.

8.4 Care of the Li-ion battery

Avoid entrance of moisture.
Charge the battery fully before using it for the first time.

8.5 Maintenance

WARNING
