WARNING! Read all safety warnings
and all 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
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

3
Compact circular saw WX427
of these devices can reduce dust-related
hazards.
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 work to
be performed. Use of the power tool for
operations different from those intended
could result in a hazardous situation.
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
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 or its own cord.
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.

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.

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 may 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.

5
Compact circular saw WX427
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.

Cut-off machine safety warnings
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 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

6
Compact circular saw WX427
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. lncorrectly 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.
I) 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. lf 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 pul1 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 youto 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. lnvestigate 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.

are pressed on the cord.Then restore the cover.
NOTE: Pay attention that “+/-” of the batteries are the
same as the illustration on the machine.
8. RECOMMENDATION THAT THE TOOL ALWAYS
be supplied via a residual current device with a rated
residual current of 30 mA or less.
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.
1. MAKING CROSS CUTS AND RIP CUTS
WARNING: To avoid sudden kick-back,
never start with the stationary blade in
contact with the work.
Always start the saw and allow it to reach full
speed before plunging into work material.
a). ALWAYS use your saw with your hands
positioned correctly.
WARNING: Always maintain proper
control of the saw to make sawing safer
and easier. Loss of control of the saw could
cause an accident resulting in possible serious
injury.
b). When making cross or rip cuts, align your
line of cut with the center of the “V” notch
located on the front of the saw’s base.
c). Since the thickness of blades varies, make
a trial cut in scrap material along the guideline
to determine how much, if any, you should
offset the blade from the guideline to allow for
the blade thickness to get an accurate cut.
MAKING RIP CUTS
Always use a guide when making long rip
cuts with your saw.You can use any suitable
straight edge clamped to the work or the
parallel guide that is included with your saw.
2. POCKET CUTTING (SOFT MATERIALS
ONLY)
This operation requires much skill with a saw
and must only be carried out by a qualified
person.
WARNING: The blade teeth are
exposed during this operation so
proceed with extreme caution.
Clearly mark the area to be cut. Set the depth
of cut on the saw. Position the saw over the
marked area with the front edge of the base
plate resting on the work surface and cutting
guide aligned with marked line on workpiece.
Ensure the blade is not touching but is close
to the work surface.The moving lower guard
must be rotated open by using lever. Switch
the saw on and gently swing the blade down
into the material but maintain a pivoting force
on the front edge of the base.The moving
lower guard can now be released for normal
action of the guard.
DO NOT bind the blade in the cut; push the
saw blade forward at a rate where the blade is
not laboring.
When the cut is complete, release the trigger
safety release and switch and let the blade
come to a complete stop. DO NOT REMOVE
the saw and blade from the workpiece while
the blade is moving.This could damage your
cut (kerf), cause kickback and loss of control,
resulting in injury.
