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.
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 toolʼs 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.
PRECAUTION
Keep children and infirm persons away.
When not in use, tools should be stored out of reach of
children and infirm persons.
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.
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 offposition before connecting to
power source and/or battery pack, picking up or
carrying the tool.

CIRCULAR SAW SAFETY WARNINGS
Cutting procedures
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 the power tool by insulated gripping surfaces
only, 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 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.
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 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 sawing into existing walls
or other blind areas.
The protruding blade may cut objects that can cause
kickback.
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.
ADDITIONAL SAFETY WARNINGS
1. Use only blade diameter specified on the machine.
2. Do not use any abrasive wheel.
3. Do not use saw blades which are deformed or cracked.
4. Do not use saw blades made of high speed steel.
5. Do not use saw blades which do not comply with the
characteristics specified in these instructions.
6. Do not stop the saw blades by lateral pressure on the
disc.
7. Always keep the saw blades sharp.
8. Ensure that the lower guard moves smoothly and freely.
9. Never use the circular saw with its lower guard fixed in
the open position.
10. Ensure that the retraction mechanism of the guard
system operates correctly.
11. Wear earplugs to protect your ears during operation.
12. Never operate the circular saw with the saw blade turned
upward or to the side.
13. Ensure that the material is free of foreign matters such as
nails.

14. The saw blades range should be from 165 mm to
162 mm.
15. Disconnect the plug from the receptacle before carrying
out any adjustment, servicing or maintenance.
16. Be careful of brake kickback.
This circular saw features an electric brake that functions
when the switch is released. As there is some kickback
when the brake functions, be sure to hold the main body
securely.
17. Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
18. Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the power
switch is in the ON position, the power tool will start
operating immediately, which could cause a serious
accident.
19. When the work area is removed from the power source,
use an extension cord of sufficient thickness and rated
capacity. The extension cord should be kept as short as
practicable.
20. Avoid cutting in the state where the base has floated up
from the material.
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.
21. Support large panels to minimize the risk of blade
pinching and KICKBACK. Large panels tend to sag
under their own weight (Fig. 3). Supports must be
placed under the panel on both sides, near the line of cut
and near the edge of the panel as shown in Fig. 2.
To minimize the risk of blade pinching and kickback.
When cutting operation requires the resting of the saw
on the work piece, the saw shall be rested on the larger
portion and the smaller piece cut off.
22. Use extra caution when making a “Pocket Cut” into
existing walls or other blind areas. The protruding blade
may cut objects that can cause KICKBACK.
NEVER place your hand or fingers behind the saw
(Fig. 4). If kickback occurs, the saw could easily jump
backwards over your hand, possibly causing severe
injury.
23. WARNING: It is important to support the work piece
properly and to hold the saw firmly to prevent loss
of control which could cause personal injury. Fig. 5
illustrates typical hand support of the saw.
24. Place the wider portion of the saw base on that part
of the work piece which is solidly supported, not on
the section that will fall offwhen the cut is made. As
examples, Fig. 6 illustrates the RIGHT way to cut offthe
end of board, and Fig. 7 the WRONG way. If the work
piece is short or small, clamp is down.
DON’T TRY TO HOLD SHORT PLACES BY HAND!
25. Never attempt to saw with the circular saw held upside
down in a vise. This is extremely dangerous and can
lead to serious accidents (Fig. 8).
26. Should lever remain loosened, it will create a very
hazardous situation. Always thoroughly clamp it.
(Fig. 12)
27. It is very hazardous to allow wing bolt to remain loosened.
Always thoroughly clamp it. (Fig. 23)
28. Prior to cutting operation, make sure the material you
are going to cut. If the material to be cut is expected to
generate harmful / toxic dusts, make sure the dust bag
or appropriate dust extraction system is connected with
dust outlet tightly.
Wear the dust mask additionally, if available.
○Before starting to saw, confirm that the saw blade
has attained full-speed revolution.
○Should the saw blade stop or make an abnormal
noise while operating, promptly turn OFF the switch.
○Always take care in preventing the power cord from
coming near to the revolving saw blade.
○Using the circular saw with the saw blade facing
upwards or sideways is very hazardous. Such
uncommon applications should be avoided.
○When cutting materials, always wear protective
glasses.
○When finished with a job, pull out the plug from the
receptacle.
29. After having attached the saw blade, reconfirm that the
lock lever is firmly secured in the prescribed position.
30. Do not expose directly your eye to the light by looking
into the light.
If your eye is continuously exposed to the light, your eye
will be hurt.
31. RCD
The use of a residual current device with a rated residual
current of 30 mA or less at all times is recommended.
