General Power Tool Safety Warnings
SAFETY INFORMATION
WARNING! Read all safety warnings and all
instructions. Failure to follow the warnings and instructions
may result in electric shock, re 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
ammable 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.
Unmodied 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.

EN-3
Important - Please read these instructions fully before starting assembly
General Power Tool Safety Warnings
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 inuence 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 nger 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.

EN-4
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
Have your power tool serviced by a qualied repair
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.

EN-5
SAFETY WARNINGS 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 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.
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;

EN-6
- 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 rm 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.

EN-7
g) Use extra caution when sawing into existing walls
or other blind areas. The protruding blade may cut objects
that can cause kickback.
SAFETY INSTRUCTIONS FOR SAWS
(CIRCULAR SAW WITH OUTER PENDULUM
GUARD, OR WITH INNER PENDULUM GUARD,
OR WITH TOW 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 oor.
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.

EN-8
SAFETY INSTRUCTIONS FOR PLUNGE TYPE
SAW
Guard function
a) Check guard for proper closing before each use. Do
not operate the saw if guard does not move freely
and enclose the blade instantly. Never clamp or
tie the guard so that the blade is exposed. If saw is
accidentally dropped, guard may be bent. Check to make sure
that guard moves freely and does not touch the blade or any
other part, in all angles and depths of cut.
b) Check the operation and condition of the guard
return spring. If the guard and the spring are not
operating properly, they must be serviced before
use. Guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
c) Assure that the base plate of the saw will not shift
while performing the “plunge cut” when the blade
bevel setting is not at 90°. Blade shifting sideways will
cause binding and likely kick back.
d) Always observe that the guard is covering the
blade before placing saw down on bench or oor.
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 RULES FOR YOUR
CIRCULAR SAW
1. Use only saw blades recommended by the manufacturer, which
conform to EN 847-1, if intended for wood and analogous
materials.
2. Do not use any abrasive wheels.
3. Use only blade diameter(s) in accordance with the markings.
4. Identify the correct saw blade to be used for the material to be
cut.
5. For your safety use, always control your saw by
your two hands.

Wear ear protection.
Vibration Information
Vibration total values (triax vector sum) determined according to EN 60745:
Vibration emission
value
Cutting wood ah,W = 6.084 m/s2 Uncertainty K = 1.5 m/s²
Cutting metal ah,M = 5.810 m/s2 Uncertainty K = 1.5 m/s²
The declared vibration total value and the declared noise emission value have been
measured in accordance with a standard test method and may be used for comparing one
tool with another.
The declared vibration total value and the declared noise emission value may also be
used in a preliminary assessment of exposure.
WARNING: The vibration and noise emissions during actual use of the power tool
can differ from the declared value depending on the ways in which the tool is used
especially what kind of workpiece is processed dependant on the following examples and
other variations on how the tool is used:
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained.
The use of the correct accessory for the tool and ensuring it is sharp and in good condition.
The tightness of the grip on the handles and if any anti vibration and noise accessories are used.
And the tool is being used as intended by its design and these instructions.

EN-15
This tool may cause hand-arm vibration syndrome if its use is not
adequately managed.
WARNING: To be accurate, an estimation of exposure level in the actual conditions
of use should also take account of all parts of the operating cycle such as the times
when the tool is switched off and when it is running idle but not actually doing the job. This
may signicantly reduce the exposure level over the total working period.
Helping to minimise your vibration and noise exposure risk.
Always use sharp chisels, drills and blades.
Maintain this tool in accordance with these instructions and keep well lubricated (where
appropriate).
If the tool is to be used regularly then invest in anti vibration and noise accessories.
Plan your work schedule to spread any high vibration tool use across a number of days.
OPERATING INSTRUCTIONS
NOTE: Before using the tool, read the instruction book carefully.
Intended use:
The tool is intended for ripping and cross-cutting wood and other materials in straight cutting
lines, while resting rmly on the work piece.
Assembly and Operation
1. SAW BLADE ASSEMBLY AND REMOVING (SEE FIG. A)
WARNING:
•Unplug the saw before operation.
•Wear protective gloves when mounting the saw blade. Touch the saw
blade directly is dangerous.
• Only use saw blades tting for this machine.
•Do not use grinding discs on this cutting tool under any
circumstances.
NOTE: Use spanner to tighten the saw blade.
WARNING: When mounting, ensure the cutting direction of the teeth (direction of
arrow on saw blade) and the direction of rotation arrow above the blade guard match.
NOTE: Never use a blade that is too thick to allow the blade clamping washer(18) to
engage with the at side of the spindle.
Washer must be tted when assembling disc.
2. SAFETY ON/OFF SWITCH (SEE FIG. B1)
To switch the machine on, pull the on/off switch (11) back.
Release the on/off switch (11) to switch off.

EN-16
NOTE: When the machine is not in use, the lock off button(2) rests against the blade
guard in order to block the plunge function and prevent the blade from being exposed
unnecessarily.
3. OPERATION OF SAW (SEE FIG. B2)
To operate the machine:
1. Pull the on/off switch(11) back with one hand;
2. Push the guard lock off button(2) with another hand;
3. Press the handle to cut with your two hands.
4. CROSS AND RIP CUTTING (SEE FIG. C1, C2)
WARNING: To avoid sudden kick-back, never start a stationary blade while it is in
contact with the work piece.
Set the speed to maximum before commencing to plunge.
The blade teeth are exposed when operation!.
a).
FOR YOUR SAFETY USE, ALWAYS CONTROL YOUR SAW BY YOUR TWO HANDS.
WARNING: Always maintain proper control of the saw to make sawing safer and
easier. Loss of control of the saw may cause serious injury.
b). When making cross or rip cuts, align your line of cut with the center of the “V” (blade
alignment indicator), located on the front of the saw’s base (SEE FIG. C1).
c). Since the thickness of blades vary, make a trial cut in scrap material along your cut mark
to determine how much, if any, you should offset the blade from the cut mark to allow for the
blade thickness to get an accurate cut.
MAKING RIP CUTS (SEE FIG. C2)
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 included in the machine.
5. CUTTING DEPTH ADJUSTING (SEE FIG. D1, D2)
NOTE: The correct choice of cutting depth can improve ease of cutting and cut quality.
Always use the minimum cut depth required for your particular cut, which should just
cut through the material plus a small allowance e.g. 3 mm.
Excessive cutting depth increases splintering in wood, and causes severe chatter in sheet
aluminum (which can quickly blunt the blade).
Maximum depth can be used when cutting internal cut-outs in wood as this reduces the
overcutting required.
1) Determine the desired depth according to the thickness of the material plus a blade
allowance of 3 mm.
2) Unlock the depth of cut adjustment and lock lever . (SEE FIG. D1)
3) Slide the depth of cut indicator to the desired depth of cut. Push the depth of cut
adjustment and lock lever down . (SEE FIG. D2)
When you do plunge or pocket cutting into the middle (or interior) of the work piece,
through the narrow slot, you can see the cutting mark you drew and the location where the
blade will plunge into the work piece, based on the selected blade depth. (See Fig. D3)
Always practice in a scrap work piece to become familiar with this cutting operation. The
selected depth of cut is now set. When the saw’s blade is manually lowered, the blade will
be below the base at the selected depth.

EN-17
6. PARALLEL GUIDE (SEE FIG. E1, E2)
The parallel guide is used for making parallel cuts on workpiece edge at a chosen
distance. The distance is from the straight edge tting the parallel guide closely to the
center of the “V” (blade alignment indicator)(E2).
It can be used on either side of the base plate (9).
7. POCKET CUTTING (SEE FIG. F1, F2)
Only professionals can do pocket cutting!
Clearly mark the area to be cut.
Note: DO NOT REMOVE the saw and blade from the workpiece while the blade is moving.
It may damage the cut (kerf), cause kickback and loss of control, and result in injury.
8. SAW DUST REMOVAL (SEE FIG. G)
Vacuum adapter (5) attaches the dust extraction outlet (4) to a vacuum cleaner (sold
separately). We recommend you to use the vacuum cleaner for it keeping the work area
clean. It increases cut visibility and reduces airborne dust drastically. It also keeps dust
away from the working environment.
WORKING HINTS FOR YOUR CIRCULAR SAW
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 signicantly
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 ner cuts, more than 40
teeth for very ne cuts into delicate surfaces, diamond for tile, cement board, etc.
Only use saw blades recommended.
For your safety ,Please hold the handle of the saw with two hands when
you are operating the saw.
MAINTENANCE
Remove the plug from the socket before carrying out any adjustment, servicing or
maintenance.
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. Occasionally you may
see sparks through the ventilation slots. This is normal and will not damage your power tool.
If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or
similarly qualied persons in order to avoid a hazard.
