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. 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.

5.1.1 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 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 oper-

ating 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. 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 con-

ditions. 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 the risk of electric shock.

e) When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of

en

5

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

en

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

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 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
awayfrom 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 preven-

tive 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

maintained 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

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 desig-

nated 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 termi-

nals 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.

Liquid ejected from the battery may cause irrita­tion or burns.

6

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 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 workpiece.

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 platform. It is important to support the

work properly to minimize body exposure, blade
binding, or loss of control.

e) Hold power tool by insulated gripping surfaces,

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 shock the operator.

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

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. Unsharp-

ened 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.

5.2.3 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

en

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. Be aware of the time it takes for the
blade to stop after switch is released.

5.3 Additional safety instructions

5.3.1 Personal safety

a) Wearear 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) Do not operate the power tool without the pro-

tective devices that belong to it.

d) Operate the power tool only as intended and

when it is in faultless condition.

e) Improve the blood circulation in your fingers by

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

f) Switch the power tool on only after bringing it

into position at the workpiece.

g) Remove the battery before storing or transport-

ing the power tool.

h) Always guide the power tool away from your

body when working with it.

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

blade by pressing it to the side.

k) Do not touch the clamping flange or the clamp-

ing screw while the power tool is running.

l) Never press the drive spindle lock button while

the saw blade is rotating.

m) Never direct the power tool toward persons.
n) 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.

o) 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.

p) Pay attention to the direction in which the metal

chips fly when sawing. The chips are hot and

may cause fires or lead to burning and cutting
injuries.

q) Children must be instructed not to play with the

power tool.

r) The power tool is not intended for use by chil-

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

s) WARNING: Some dust created by grinding,

sanding, 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 chemically­treated 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.

8

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.

injury through contact with caustic substances
may otherwise result.

d) Do not use batteries other than those approved

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 indi-

cate that it is faulty. Place the tool at a location

where there is no risk of causing a fire (at least 3
meters away from flammable materials), where
it can be kept under observation and allowed to
cool. Contact Hilti Service after the battery has
been allowed to cool.

5.3.5 Work area

a) Ensure that the workplace is well lit.
b) Ensure that the workplace is well ventilated.

Exposure to dust at a poorly ventilated workplace
may result in damage to the health.

5.3.6 Personal protective equipment

en

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 bat-

teries and do not subject them to temperatures
over 80°C (176°F). A risk of fire, explosion or

The user and any other persons in the vicinity must
wear ANSI Z87.1-approved eye protection, a hard
hat, ear protection, protective gloves and breathing
protection while the machine is in use.

7.3 Sawing along a line

The position of the saw blade is indicated by the
mark on the base plate. This allows accurate cuts to
be made. 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
helps ensure a more accurate cut.

1. Secure the workpiece to prevent movement.

2. Position the workpiece so that the saw blade is
free to rotate beneath it.

3. Check to ensure that the on / off switch on the
power tool is in the “off” position.

4. Fit the battery into the power tool.

switch the power tool on by pressing the on/off
button.

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

7.4 Sawing using the rip fence (accessory)

Use of the single arm rip fence allows precise cuts to
be made along the edge of the workpiece, or strips of
even width to be cut.
The rip fence can be fitted on either side of the base
plate.

7.5 Fitting / adjusting the parallel guide (rip
fence) 5

1. Remove the battery from the power tool.

2. Press the clamp together.

Wear protective gloves when emptying the chip
collector. The metal chips are sharp-edged and may

be hot.

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.

When the power tool is in use you can check with
the aid of the viewing window whether the collector
is full.

1. Remove the battery from the tool.

12

4. Check that moving parts on the power tool are
working properly and not jamming. Check also
whether parts are broken or damaged in such a
way that may cause the power tool to malfunc­tion.

8. Care and maintenance

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

8.1 Care of insert tools

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
impact-resistantplastic. 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
discharge will be stopped automatically before the
battery cells suffer damage.

en

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. Have the power tool 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.
