GENERAL POWER TOOL
SAFETY WARNINGS
WARNING Read all safety warnings,
instructions, illustrations and specifications
provided with this power tool.
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 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, 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.
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 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 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. 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

3
Compact Circular Saw WX437
WX437.X
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.
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

4
Compact Circular Saw WX437
WX437.X
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 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
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

5
Compact Circular Saw WX437
WX437.X
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.
ADDITIONAL SAFETY RULES
1. Always wear a dust mask.
ADDITIONAL SAFETY RULES
FOR YOUR CIRCULAR SAW
1. Use only saw blades recommended by the
manufacturer, which conform to EN 847-1, if

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.
MAINTAIN TOOLS WITH CARE
Remove the plug from the socket before carrying out
any adjustment, servicing or maintenance.
Keep tools sharp and clean for better and safer
performance. Follow instructions for lubricating and
changing accessories. Inspect tool cords periodically and
if damaged, have repaired by authorized service facility.
Your power tool requires no additional lubrication or
