GENERAL POWER TOOL
SAFETY WARNINGS
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.
1WORK 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.
2ELECTRICAL 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, nonskid 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 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. 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.
FURTHER SAFETY
INSTRUCTIONS FOR ALL
SAWS
Kickback causes and related warnings
- 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
Electric Circular Saw
WX423
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 arm 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, center 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 minimize 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.
SAFETY INSTRUCTIONS
FOR SAWS WITH INNER
PENDULUM GUARD
Lower Guard Function
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.
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.

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 maintenance. There are no user serviceable
parts in your power tool. Never use water or
chemical cleaners to clean your power tool.
Wipe clean with a dry cloth. Always store
your power tool in a dry place. Keep the
motor ventilation slots clean. Keep all working
controls free of dust.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service
agent or similarly qualified persons in order to
avoid a hazard.
Periodically clear dust and chips from guard
and base to ensure proper performance.
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,
