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

c) When battery pack is not in use, keep it away
from other metal objects, like paper clips, coins,
keys, nails, screws or other small metal objects,
that can make a connection from one terminal to
another.
Shorting the battery terminals together may cause
burns or a fire.
d) Under abusive conditions, liquid may be ejected
from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid
contacts eyes, additionally seek medical help.
Liquid ejected from the battery may cause irritation or
burns.
6) 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.
CORDLESS 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.
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.

English
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. Do not allow foreign matter to enter the hole for
connecting the rechargeable battery.
2. Never disassemble the rechargeable battery and
charger.
3. Never short-circuit the rechargeable battery.
Shortcircuiting the battery will cause a great electric
current and overheat. It results in burn or damage to the
battery.
4. Do not dispose of the battery in fire. If the battery is burnt,
it may explode.
5. When using this unit continuously, the unit may overheat,
leading to damage in the motor and switch. Therefore,
whenever the housing becomes hot, give the saw a
break for a while.
6. Do not insert object into the air ventilation slots of the
charger. Inserting metal objects or inflammables into the
charger air ventilation slots will result in electrical shock
hazard or damaged charger.
7. Bring the battery to the shop from which it was purchased
as soon as the post-charging battery life becomes too
short for practical use. Do not dispose of the exhausted
battery.
8. Use only blade diameter specified on the machine.
9. Do not use any abrasive wheel.
10. Do not use saw blades which are deformed or cracked.
11. Do not use saw blades made of high speed steel.
12. Do not use saw blades which do not comply with the
characteristics specified in these instructions.
13. Do not stop the saw blades by lateral pressure on the
disc.
14. Always keep the saw blades sharp.
15. Ensure that the lower guard moves smoothly and freely.
16. Never use the circular saw with its lower guard fixed in
the open position.
17. Ensure that the retraction mechanism of the guard
system operates correctly.
18. Never operate the circular saw with the saw blade turned
upward or to the side.
19. Ensure that the material is free of foreign matters such as
nails.
20. The saw blades range should be from 165 mm to
150 mm.
21. Since the saw blade will extend beyond the lower surface
of the lumber, place the lumber on a workbench when
cutting. If a square block is utilized as a workbench,
select level ground to ensure it is properly stabilized. An
unstable workbench will result in hazardous operation.
(Fig. 2)
To avoid possible accident, always ensure that the
portion of lumber remaining after cutting is securely
anchored or held in position.
22. 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.
23. Do not fix and secure the switch lock. Besides, keep
your finger offthe switch trigger when the circular saw is
being carried around. Otherwise, the main body switch
can be inadvertently turned ON, resulting in unexpected
accidents.
24. 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.
25. Before starting to saw, ensure that the saw blade has
reached full speed revolution.
26. Should the saw blade be stopped or made an abnormal
noise during operation, turn offthe switch immediately.
27. Twisting and forcibly pressing the saw during cutting can
result in unreasonable pressure on the motor, so try to go
straight quietly.
28. Avoid cutting operation in a state where the base bottom
is afloat from the material being cut. Otherwise, the
motor can get locked.
29. Preparing and checking the work environment. Make
sure that the work site meets all the conditions laid forth
in the precautions.
30. Make sure that the battery is installed firmly. If it is as all
loose it could come offand cause an accident.
31. When finished with a job, pull out the battery from the
main body.
32. After having attached the saw blade, reconfirm that the
lock lever is firmly secured in the prescribed position.
33. If the left-hand bolt is worked using other tools than
the provided box wrench, excessive tightening and
insufficient tightening may take place resulting in injury.
34. After adjusting cutting depth, make sure to securely
tighten the lever. Failure to do so may result in injury.
(Fig. 3)
35. After adjusting the angle of inclination, make sure to
securely tighten the wing nut. Failure to do so may result
in injury. (Fig. 4)
36. Values of the inclined gauge provided on the base merely
serve as a rough guideline. For cutting operation at an
inclined posture, use the circular saw after adjusting
the angle between the base and the saw blade with a
protractor, etc.
37. Pull out battery before carrying out any adjustment,
servicing or maintenance.
38. Ensure that the switch is in the OFF position. If the battery
installed to power tool while the switch is in the ON
position, the power tool will start operating immediately,
which could cause a serious accident.
39. If the main body is left as it is with the battery inserted,
there can be a case where the [switch lock] touches
the floor and/or wall surface and lights up continuously,
depending on the direction of the body. Be careful,
since continuous lighting can easily make a full-charged
battery go dead.
40. 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. 5).
41. Keep the light ON during cutting operation only. If
it is lit ON in other cases, the main body switch can
be inadvertently turned ON, resulting in unexpected
accidents.
42. 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.
43. Never touch moving parts.
Never place your hands, fingers or other body parts near
the tool’s moving parts.
44. Never operate without all guards in place.
Never operate this tool without all guards or safety
features in place and in proper working order. If
maintenance or servicing requires the removal of a
guard or safety feature, be sure to replace the guard or
safety feature before resuming operation of the tool.
45. NEVER leave tool running unattended. Turn power off.
Don’t leave tool until it comes to a complete stop.
