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.
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
atmospheres, 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
operating a power tool. Distractions can cause
you to lose control.
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
conditions. 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 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.
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
balance 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 and clothing
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.
h) 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.
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 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.
d) 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.
e) 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

4
Compact Circular Saw WX439
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.
h) 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.
5) 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.
SAFETY INSTRUCTIONS
FOR ALL SAWS
Cutting procedures
a) DANGER: Keep hands away from
cutting area and the blade. 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 the workpiece in your hands or
across your leg while cutting. 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.
e) Hold the power tool by insulated gripping
surfaces, when performing an operation
where the cutting tool 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.
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 off-centre, 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.
FURTHER SAFETY
INSTRUCTIONS FOR ALL
SAWS
Kickback causes and related warnings
— kickback is a sudden reaction to a pinched, jammed
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 jammed 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 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 so that the
saw teeth are not engaged into the material.
If a saw blade binds, 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 the cut. If blade adjustment shifts while
cutting, it may cause binding and kickback.

5
Compact Circular Saw WX439
g) Use extra caution when sawing into existing
walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
SAFETY INSTRUCTIONS
FOR CIRCULAR SAW WITH
INNER PENDULUM GUARD
Lower guard function
a) Check the lower guard for proper closing
before each use. Do not operate the saw if
the lower guard does not move freely and
close instantly. Never clamp or tie the lower
guard into the open position. If the saw
is accidentally dropped, the 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) The lower guard may be retracted manually
only for special cuts such as “plunge cuts”
and “compound cuts.” Raise the lower
guard by retracting handle and as soon as
the 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 the 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
RULES FOR YOUR
CIRCULAR SAW
1. Use only saw blades recommended by the
manufacturer, which conform to EN 847-1, if
intended for wood and analogous materials.
2. Do not use any abrasive wheels.
3. Use only blade diameter(s) in accordance with the
markings.
4. Identify the correct saw blade to be used for the
material to be cut.
5. Use only saw blades that are marked with a speed
equal or higher than the speed marked on the
tool.
ADDITIONAL SAFETY
RULES FOR YOUR CUTTING-
OFF MACHINES
a) The guard provided with the tool must be
securely attached to the power tool and
positioned for maximum safety, so the least
amount of wheel is exposed towards the
operator. Position yourself and bystanders
away from the plane of the rotating wheel.
The guard helps to protect operator from broken
wheel fragments and accidental contact with
wheel.
b) Use only bonded reinforced or diamond cut-
off wheels for your power tool. Just because
an accessory can be attached to your power tool,
it does not assure safe operation.
c) The rated speed of the accessory must
be at least equal to the maximum speed
marked on the power tool. Accessories
running faster than their rated speed can break
and fly apart.
d) Wheels must be used only for recommended
applications. For example: do not grind with
the side of cut-off wheel. Abrasive cut-off
wheels are intended for peripheral grinding, side
forces applied to these wheels may cause them to
shatter.
e) Always use undamaged wheel flanges that
are of correct diameter for your selected
wheel. Proper wheel flanges support the wheel
thus reducing the possibility of wheel breakage.
f) Do not use worn down reinforced wheels
from larger power tools. Wheels intended for
a larger power tool are not suitable for the higher
speed of a smaller tool and may burst.
g) The outside diameter and the thickness of
your accessory must be within the capacity
rating of your power tool. Incorrectly sized
accessories cannot be adequately guarded or
controlled.
h) The arbour size of wheels and flanges must
properly fit the spindle of the power tool.
Wheels and flanges with arbour holes that do not
match the mounting hardware of the power tool
will run out of balance, vibrate excessively and
may cause loss of control.
i) Do not use damaged wheels. Before each
use, inspect the wheels for chips and
cracks. If power tool or wheel is dropped,
inspect for damage or install an undamaged
wheel. After inspecting and installing the
wheel, position yourself and bystanders
away from the plane of the rotating wheel
and run the power tool at maximum no load
speed for one minute. Damaged wheels will
normally break apart during this test time.
j) Wear personal protective equipment.
Depending on application, use face
shield, safety goggles or safety glasses.
As appropriate, wear dust mask, hearing
protectors, gloves and shop apron capable

6
Compact Circular Saw WX439
of stopping small abrasive or workpiece
fragments. The eye protection must be
capable of stopping flying debris generated
by various operations. The dust mask or
respirator must be capable of filtrating particles
generated by your operation. Prolonged exposure
to high intensity noise may cause hearing loss.
k) Keep bystanders a safe distance away from
work area. Anyone entering the work area
must wear personal protective equipment.
Fragments of workpiece or of a broken wheel
may fly away and cause injury beyond immediate
area of operation.
l) Hold the power tool by insulated gripping
surfaces only, when performing an
operation where the cutting accessory
may contact hidden wiring or its own cord.
Cutting accessory contacting a “live” wire may
make exposed metal parts of the power tool
“live” and could give the operator an electric
shock.
m) Position the cord clear of the spinning
accessory. If you lose control, the cord may be
cut or snagged and your hand or arm may be
pulled into the spinning wheel.
n) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning wheel may grab the surface and pull the
power tool out of your control.
o) Do not run the power tool while carrying
it at your side. Accidental contact with the
spinning accessory could snag your clothing,
pulling the accessory into your body.
p) Regularly clean the power tool’s air vents.
The motor’s fan will draw the dust inside the
housing and excessive accumulation of powdered
metal may cause electrical hazards.
q) Do not operate the power tool near
flammable materials. Sparks could ignite these
materials.
r) Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
KICKBACK AND RELATED
WARNINGS
- Kickback is a sudden reaction to a pinched or
snagged rotating wheel. Pinching or snagging causes
rapid stalling of the rotating wheel which in turn
causes the uncontrolled power tool to be forced in
the direction opposite of the wheel’s rotation at the
point of the binding.
- For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into the
surface of the material causing the wheel to climb
out or kick out. -The wheel may either jump toward
or away from the operator, depending on direction
of the wheel’s movement at the point of pinching.
Abrasive wheels may also break under these
conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and can
be avoided by taking proper precautions as given
below.
a) Maintain a firm grip on the power tool
and position your body and arm to allow
you to resist kickback forces. Always use
auxiliary handle, if provided, for maximum
control over kickback or torque reaction
during start-up. The operator can control torque
reactions or kickback forces, if proper precautions
are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body in line with the
rotating wheel. Kickback will propel the tool in
direction opposite to the wheel’s movement at the
point of snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and
snagging the accessory. Corners, sharp edges
or bouncing have a tendency to snag the rotating
accessory and cause loss of control or kickback.
e) Do not attach a saw chain, woodcarving
blade, segmented diamond wheel with
a peripheral gap greater than 10 mm or
toothed saw blade. Such blades create frequent
kickback and loss of control.
f) Do not “jam” the wheel or apply excessive
pressure. Do not attempt to make an
excessive depth of cut. Overstressing the
wheel increases the loading and susceptibility to
twisting or binding of the wheel in the cut and the
possibility of kickback or wheel breakage.
g) When wheel is binding or when interrupting
a cut for any reason, switch off the power
tool and hold the power tool motionless
until the wheel comes to a complete
stop. Never attempt to remove the wheel
from the cut while the wheel is in motion
otherwise kickback may occur. Investigate
and take corrective action to eliminate the cause
of wheel binding.
h) Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed
and carefully re-enter the cut. The wheel
may bind, walk up or kickback if the power tool is
restarted in the workpiece.
i) Support panels or any oversized workpiece
to minimize the risk of wheel pinching and
kickback. Large workpieces tend to sag
under their own weight. Supports must be
placed under the workpiece near the line of cut
and near the edge of the workpiece on both sides
of the wheel.
j) Use extra caution when making a “pocket
cut” into existing walls or other blind areas.
The protruding wheel may cut gas or water
pipes, electrical wiring or objects that can cause
kickback.

WORKING HINTS FOR YOUR
TOOL
If your power tool becomes too hot, please run your
circular saw no load for 2-3 minutes to cool the
motor. Avoid prolonged usage at very low speeds.
Protect saw blades against impact and shock. Cutting
with extreme force can significantly reduces the
performance capability of the tool and reduces the
service life of the saw blade. Sawing performance
and cutting quality depend essentially on the
condition and the tooth count of the saw blade.
Therefore, use only sharp saw blades that are suited
for the material being cut.
Choice of blades: 24 teeth for general work, approx.
40 teeth for finer cuts, more than 40 teeth for very
fine cuts into delicate surfaces, diamond for tile,
cement board, etc.
Only use saw blades recommended.
