General Power Tool Safety Warnings
Warning
Read all safety warnings, instructions, illustrations
and specifications provided with this power tool.
Failure to follow all instructions listed below 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.
General Power Tool Safety Warnings– Work area
safety
•Keep work area clean and well lit. Clutter or dark areas
invite accidents.
•Do not operate power tools in explosive atmosphere,
such as in the presence of flammable liquids, gases or
dust. Power tools create sparks which may ignite the dust
or fumes.
•Keep children and bystanders away while operating a
power tool. Distractions can cause you to lose control.
General Power Tool Safety Warnings– Electrical
safety
•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.
•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.
•Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of
electric shock.
•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.
•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.
•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.
General Power Tool Safety Warnings– Personal
safety
•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.
Use personal protective equipment. Always
wear eye protection. Protective equipment such
as a dust mask, non-skid safety shoes, hard hat or
hearing protection used for appropriate conditions
will reduce personal injuries.
•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.
•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.
•Do not overreach. Keep proper footing and balance at
all times. This enables better control of the power tool in
unexpected situation.
•Dress properly. Do not wear loose clothing or
jewellery. Keep your hair and clothing away from
moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
•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.
•Do not let familiarity gained from frequent use of tools
allow you to become complacent and ignore tool
safety principles. A careless action can cause severe
injury within a fraction of a second.

General Power Tool Safety Warnings– Power tool
use and care
•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.
•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.
•Disconnect the plug from the power source and/or
remove the battery pack, if detachable, 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.
•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 dangerous in the hands of untrained users.
•Maintain power tools and accessories. 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.
•Keep cutting tools sharp and clean. Properly maintained
cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
•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.
•Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
General Power Tool Safety Warnings– Battery tool
use and care
•Recharge only with 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.
•Use power tools only with specifically designed battery
packs. Use of any other battery packs may create a risk of
injury and fire.
•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.
•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.
•Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behaviour resulting in fire, explosion or risk
of injury.
•Do not expose a battery pack or tool to fire or
excessive temperature. Exposure to fire or temperature
above 130°C may cause explosion.
•Follow all charging instructions and do not charge the
battery pack or tool outside the temperature range
specified in the instructions. Charging improperly or at
temperatures outsides the specified range may damage
the battery and increase the risk of fire.
General Power Tool Safety Warnings– Service
•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.
•Never service damaged battery pack. Service of battery
packs should only be performed by the manufacturer or
authorized service providers.
Device-specific safety warnings for portable
circular saws
Safety warnings for all saws
Sawing methods
•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.
•Do not reach underneath the workpiece. The guard
cannot protect you from the blade below the workpiece.
•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.
•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 minimise body
exposure, blade binding, or loss of control.

EN 5
mini cordless portable circular saw PCSS 05-20V
•Hold the power tool by its insulated gripping surfaces
when performing an operation where the cutting
accessory may contact hidden wiring or its own cord.
Contact with a "live" wire will also make exposed metal
parts of the power tool "live" and could give the operator
an electric shock.
•When ripping, always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces the
chance of blade binding.
•Always use saw 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.
•Never use damaged or incorrect blade washers or
bolts. The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of
operation.
Further safety warnings for all saws
Kickback causes and related warnings
A 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
workpiece 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.
•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.
•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 backwards while the blade is
in motion or kickback may occur. Investigate and take
corrective actions to eliminate the cause of blade binding.
•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.
•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.
•Do not use dull or damaged blades. Unsharpened or
improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
•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.
•Use extra caution when sawing into existing walls or
other blind areas. The protruding blade may cut objects
that can cause kickback.
Safety warnings for circular saws with pendulum guard
and circular saws with tow guard – Lower guard function
•Check the lower guard for proper closure before each
use. Do not operate the saw if the lower guard does
not move freely and close immediately. Never clamp or
tie the lower guard in the open position. The lower
guard may be bent if the saw accidentally falls to the floor.
Use the retracting lever to raise the guard and make sure
that it moves freely and does not touch the blade or any
other part of the saw at all cutting angles and depths of
cut.
•Check that the lower guard spring operates correctly.
If the guard and spring do not operate correctly, have
the saw serviced before use. Lower guard may operate
sluggishly due to damaged parts, gummy deposits, or a
build-up of debris.
•Lower guard may be retracted manually only for
special cuts such as "plunge cuts" and "compound
cuts". Raise lower guard by retracting lever and as
soon as blade enters the material, the lower guard
must be released. For all other sawing, the lower guard
should operate automatically.
•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.
Additional safety warnings for portable circular saws
•Do not reach into the chip ejector with your hands.
They could be injured by rotating parts.
•Do not work overhead with the saw. In this manner you
do not have sufficient control over the power tool.
•Do not use abrasive wheels.

6 EN
mini cordless portable circular saw PCSS 05-20V
•Only use saw blades of a diameter specified in the
technical data Using a blade of the wrong size may leave
the blade without proper protection or affect the
functioning of the guard.
•Use suitable detectors to determine if utility lines are
hidden in the work area or call the local utility
company for assistance. Contact with electrical lines
may result in fire and electric shock. Damaging a gas line
may lead to an explosion. Penetrating a water line causes
property damage and may cause an electric shock.
•Do not operate the power tool stationary. It is not
designed for operation with a saw table.
•Do not use high speed steel (HSS) saw blades. Such
saw blades can easily break.
•Do not saw ferrous metals. Red hot chips can ignite the
dust extraction.
•If the supply cord is damaged, it must be replaced with
a special connection line that can be obtained from the
manufacturer or his customer service.
•Ensure a steady forward motion of the tool. An
insufficient forward motion may result in the overheating of
the saw teeth or the melting of the workpiece to be
processed.

Operation
Tips and notes on handling the circular saw
General information:
• Keep the venting slots clear to prevent the motor from
overheating.
• Only use intact, flawless saw blades. Saw blades can be
damaged by shocks or impacts. Bent, blunt or otherwise
damaged saw blades could break. The sawing
performance and cutting quality essentially depend on the
saw blade's condition and the shape of the teeth.
• Check the saw blade for correct fit before every
application.
• Before every application, make sure that you have selected
the correct saw blade for the intended use.
• Before every application, check whether you need a dust
bag or dust extraction system.
– Harmful dusts are produced when processing wood,
particularly beech and oak. Beech and oak dust is
considered carcinogenic, especially in combination with
certain wood treatment additives such as chromate or
wood preservatives. Wear a protective mask.
– Dusts from materials containing leaded paint or
minerals can be harmful to health. Wear a protective
mask.
– Long, spiral chips are produced when processing
spruce.
• The falling part of the workpiece should be located on the
right-hand side of the power tool so that the larger part of
the workpiece remains in full contact with the supporting
table or similar.
• Guide the power tool by pushing slightly and evenly in the
cutting direction. Pushing too hard reduces the blade life
and can damage the power tool.
• If you are sawing along a drawn line, guide the power tool
along the respective notch.
• Tear-out of the edges cut into sensitive surfaces (e.g.
plasterboard or coated chipboard) can be prevented by
covering the cutting edges with masking tape. In this case,
the cutting line can also be drawn on the masking tape to
protect the workpiece surface.
• Non-coated saw blades can be protected against corrosion
by applying a thin layer of acid-free oil. Remove any oil
before starting to saw to prevent oil residues from reaching
the wood.
• When sawing lightweight construction materials, observe
the legal regulations and recommendations of the material
manufacturers.
Sawing wood:
• Before sawing wood, chipboards, building materials etc.,
check the above for foreign objects, e.g. nails, screws or
similar. If required, remove the foreign objects or use a
suitable, sharp saw blade.
• The choice of the saw blade depends on the type of
application (longitudinal or cross cuts) as well as the type
and quality of wood.
• If the saw blade gets jammed in the workpiece, switch off
the power tool immediately. The sawing gap should be
slightly widened with a suitable tool so that you can pull
out the power tool.
• Switch on the power tool and guide it towards the
workpiece to be processed. Place the guide shoe on the
surface of the workpiece. Process the workpiece with an
even forward motion and contact pressure. After
completing the sawing operation, switch off the power
tool.
Sawing non-ferrous metals:
• Metal dusts can be harmful to health. Wear a protective
mask.
• Only use a sharp saw blade suitable for non-ferrous
metals. This guarantees a clean cut and prevents the saw
blade from getting jammed.
• Only hold the power tool against the workpiece when the
tool is switched on and running. Start sawing carefully and
with little forward motion. Continue sawing with little
forward motion and without interrupting.
• When sawing narrow profiles, you should start on the
narrow side. When sawing U-profiles, you should start on
the open side. Long profiles should be supported to
prevent the saw blade from getting jammed and thus to
avoid the risk of a kickback.
