3. 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.

4
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.

5
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.
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.

6
SAFETY WARNINGS COMMON FOR CUTTING OPERATIONS:
a) This power tool is intended for cutting, Read all safety warnings,
instructions, illustrations, and specifications provided with this tool.
Failure to follow all instructions listed below may result in electric shock,
fire and/or serious injury
b) Do not use accessories which are not specifically designed and
recommended by the tool manufacturer. Just because the 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) 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.
e) Wear personal protective equipment. Depending on application, use
face shield, safety goggles or safety glasses. As appropriate, wear dust
mask, hearing protectors, gloves and workshop 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.
f) 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 accessory may fly away and
cause injury beyond immediate area of operation.
g) 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.

7
h) 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 accessory.
i) Never lay the power tool down until the accessory has come to a
complete stop. The spinning accessory may grab the surface and pull
the power tool out of your control.
j) 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.
k) 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.
l) Do not operate the power tool near flammable materials. Sparks could
ignite these materials.
m) 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,
backing pad, brush or any other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction opposite of the
accessory’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.

8
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 the area where power tool will move if
kickback occurs. 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 or toothed saw blade.
Such blades create frequent kickback and loss of control.
4. APPLICATION：
1. Cutting various types of wood.
2. Cutting various decorative boards, thin plastic boards, and mnew types of
building materials which are soft(use a saw blade for plastic)
3. Cutting thin aluminum sheets.
4. Cutting nonmetallic materials such as slete gypsum bord, cemented excelsior
boart, etc.
MOUNTING AND DISMOUNTING THE SAW BLADE
CAUTION: To avoid serious accident, ensure that the switch is in the OFF position
and power source is disconnected.
*DISMOUNTING THE SAW BLADE
1. Set the cutting depth to maximum and place the circular saw on a stable place.
2. Keeping the lock lever depressed, carefully tum the bolt with the supplied wrench.

9
3. When the saw shaft fixed, tum the wrench counterclockwise to remove bolt and
washer.
4. While qrlpping the safety cover knod, retract the safety cover into the saw cover
and take out the saw blade.
*MOUNTLNG THE SAW BLADE
1. Install the saw blade in the reverse order to removal.
2. Wipe off the swart from the spindle, washer, etc.
3. The saw blade should be installed so that the arrow in the saw blade is aligned
with the anow on the saw cover.
4. Tighten the bolt securely.
CAUTIONS：
If a wrench other than the one supplied is used. The bolt cannot be tightened
correctly. Always use the supplied wrench before connecting the power plug, check
that if lock lever is retumed to its original position and the saw blade rotates
smoothly.
5. MAINTENANCE AND INSPECTION：
*INSPECTION TIHE SAW BLADE
Since use of dull saw blade will cause motor maltunctioning and degraded efficiently,
replace with a new one without delay if abrasion is noted.
*INSPECTING THE MOUNTING SCREWS
Regularly innect all mounting screws and ensure that they are properly tightened.
Should any of the screws be loosened, retighten then immediately. Failure up to so
could result in serious hazard.
*MALNTENANCE OF THE MOTOR
The motor un it winding is the very "heart" of the power tool. Exercise due care to
ensure the winding does not become damaged and wet with oil or water.
*INSPECTTNG THE CARBON BRUSHES

10
The motor employs carbon brushes which are consumable parts. Since an
excessively wom carbon brush could result in motor trouble, replace the carbon
brush with a new one which had the same carbon brush shown in the figure when it
becomes wom to or near the "wear limit" in addition, always keep carbon brushes
dean and ensure that they slide freely within the brush holders.
*REPLACING A CARBON BRUSH
Disassemble the brush cap with a screwdriver. The carbon brush can then be easily
removed.
