GENERAL SAFETY RULES
Safety is a combination of common sense, staying alert, and knowing how your power tool works.
SAVE THESE SAFETY INSTRUCTIONS.
WARNING: Do not operate this unit until you read this instruction manual for safety,
operation and maintenance instructions. Failure to follow all instructions listed below may
result in electric shock, fire, and/or serious personal injury.
WORK AREA SAFETY
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
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.
Keep children and bystanders away while operating a power tool. Distractions can cause you to lose
control.
ELECTRICAL SAFETY
Grounding instructions
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least
resistance for electric current and reduces the risk of electric shock. This tool is equipped with an electric
cord that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into
a matching outlet that is properly installed and grounded in accordance with ALL local codes and
ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed
by a licensed electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The
conductor with the green insulation (with or without yellow stripes) is the equipment grounding
conductor. If repair or replacement of the electric cord or plug is necessary, DO NOT connect the
equipment grounding conductor to a live terminal.
CHECK with licensed electrician or service personnel if you do not completely understand the grounding
instructions, or if you are not sure if the tool is properly grounded.
USE ONLY THREE-WIRE EXTENSION CORDS that have 3-pronged plugs and outlets that accept the
tool's plug as shown in Fig. A. Repair or replace a damaged or worn cord immediately.

6
CAUTION: In all cases, make certain the outlet in question is properly grounded. If you are not sure if it
is, have a licensed electrician check the outlet.
WARNING: Do not expose to rain or use in damp locations.
Guidelines for using extension cords
Make sure your extension cord is in good condition. When using an extension cord, be sure to use one
heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line
voltage resulting in loss of power and overheating. The table below shows the correct size to be used
according to cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
Minimum Gauge for Extension Cords (AWG)
(When using 120 V only)
Make sure your extension cord is properly wired and in good condition. Always replace a damaged
extension cord or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be
protected with a 15 A time-delayed fuse. Before connecting the motor to the power line, make sure the
switch is in the OFF position and the electric current is rated the same as the current stamped on the motor
nameplate. Running at a lower voltage will damage the motor.
WARNING: This tool must be grounded while in use to protect the operator from electric
shock.
PERSONAL SAFETY
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.
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.

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 energizing power tools that have the switch on invites accidents.
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.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the
power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and gloves away
from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
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.
POWER TOOL USE AND CARE
Do not force 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 is designed.
Do not use the power tool if switch does not turn it on or off. Any power tool that cannot be
controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source before making any adjustments, changing accessories, or
storing the power tool. Such preventive safety measures reduce the risk of starting the power tool
accidentally.
Store idle power tools out of reach of children and other untrained persons. Power tools are
dangerous in the hands of untrained users.
Maintain power tools with care. Keep cutting tools sharp and clean. Properly maintained power tools,
with sharp cutting edges are less likely to bind and are easier to control.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that
may affect the power tools operation. If damaged, have the power tool serviced before using.
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.
Save these instructions. Refer to them frequently and use them to instruct others who may use this

SPECIFIC SAFETY RULES FOR ELECTRIC COMPACT CIRCULAR
SAW
Hold power tool by insulated gripping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring. Cutting accessory contacting a “live” wire may make exposed
metal parts of the power tool “live” and could give the operator an electric shock.
Use clamps or another practical way to secure and support the workpiece to a stable platform.
Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling
hazard. Some tools with large battery packs will stand upright but may be easily knocked over.
Keep hands away from cutting area. Never reach underneath the material for any reason. Hold front
of saw by grasping the contoured gripping area. Do not insert fingers or thumb into the vicinity of the
reciprocating blade and blade clamp. Do not stabilize the saw by gripping the shoe.
Keep blades sharp. Dull blades may cause the saw to swerve or stall under pressure.
Use extra caution when cutting overhead and pay particular attention to overhead wires which may
be hidden from view. Anticipate the path of falling branches and debris ahead of time.
When cutting pipe or conduit ensure that etc.
WARNING: Always wear proper personal hearing protection that conforms to ANSI
S12.6 (S3.19) during use. Under some conditions and duration of use, noise from this
product
may contribute to hearing loss.
WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses.
Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED
SAFETY EQUIP- MENT:
ANSI Z87.1 eye protection (CAN/CSA Z94.3),
ANSI S12.6 (S3.19) hearing protection,
NIOSH/OSHA/MSHA respiratory protection.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the state of California to cause
cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
lead from lead-based paints,
crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to filter out microscopic particles.
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other
construction activities. Wear protective clothing and wash exposed areas with soap and water.
Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful
chemicals.
WARNING: Use of this tool can generate and/or disperse dust, which may cause serious
and permanent respiratory or other injury. Always use NIOSH/OSHA approved
respiratory protection appropriate for the dust exposure. Direct particles away from face
and body.
WARNING: Do not operate this tool for long periods of time. Vibration caused by the
operating action of this tool may cause permanent injury to fingers, hands, and arms. Use
gloves to provide extra cushion, take frequent rest periods, and limit daily time of use.

Cutting Procedures
WARNING: Keep hands away from the cutting area and the saw blade.
Do not reach underneath the workpiece. The guard cannot protect you from the blade below the
workpiece.
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.
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.
Hold power tool by the insulated gripping surfaces, when performing an operation where the cutting
tool may run into hidden wiring. Contact with a “live” wire will make ex- posed metal parts of the
tool “live” and shock the operator.
When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and
reduces the chance of blade binding.
Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades that do
not match the mounting hardware of the saw will run eccentrically, causing loss of control.
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 uncon-
trolled 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.
Maintain a firm grip on the saw and position your arms to allow you to resist kickback force. Always
stay to the side of the saw blade, never putting the saw blade in line with your body. The saw can
jump backwards in the event of kickback, but the operator can control kickback force if proper
precautions are taken.
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.
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.
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.
Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf
causing excessive friction, blade binding and kickback.
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.
Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut
objects that can cause kickback.

10
Lower Guard Function
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.
Check the operation of the lower guard spring. If the guard and the spring are not operating proper- ly,
they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy
deposits, or a build-up of debris.
The lower guard may be retracted manually only for special cuts such as “plunge cuts and angle cuts”.
Raise the lower guard by retracting the handle and as soon as the blade enters the material, release the
lower guard. For all other sawing operations, the lower guard should operate automatically.
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.
Safety Rules for Laser Lights
The laser light/laser radiation used in the system is Class 2 with maximum 1mW and 650nm wavelengths.
These lasers do not normally present an optical hazard, although staring at the beam may cause flash
blindness.
WARNNING: Do not stare directly at the laser beam. A hazard may exist if you deliberately
stare into the beam, please observe all safety rules as follows;
The laser shall be used and maintained in accordance with the manufacturer’s instructions.
Never aim the beam at any person or an object other than the workpiece.
The laser beam shall not be deliberately aimed at personnel and shall be prevented from being
directed towards the eye of a person for longer than 0.25s.
Always ensure the laser beam is aimed at a sturdy workpiece without reflective surfaces. I.e. wood or
rough coated surfaces are acceptable. Bright shiny reflective sheet steel or the like is not suitable for
laser use as the reflective surface could direct the beam back at the operator.
Do not change the laser light assembly with a different type. Repairs must be carried out by the laser
manufacturer or an authorized agent.
CAUTION: Use of controls or adjustments or performance of procedures other than those
specified herein may result in hazardous radiation exposure.

15
OPERATION INSTRUCTION
Switching on and off
Note: Before engaging the on/off switch, check the saw blade to see if it is fitted properly and runs
smoothly, and the blade clamp screw is well tightened.
Connect the plug to the power supply.
To start the tool, depress the unlock button (5) and press the switch trigger (6).
Release the trigger (6) to turn the tool off.
Depth adjustment
Loosen the cutting depth setting clamp (9) by lifting the lock lever.
Hold the base plate (14) flat against the body of the work piece and lift the body of the saw until the
blade is at the right depth.
Tighten the depth locking lever.
Angle adjustment
Loosen the lock lever knob for angle adjustment (11).
Adjust the base plate (14) to the desired angle between 0° to 45°.
Tighten the lock lever knob for angle adjustment (11).
Note: for best cutting results, always ensure that saw blade protrudes no more than 3 mm below
the bottom surface of the workpiece.
General cut
Mark a cutting line on the workpiece.
Rest the front part of the shoe flat on the workpiece surface with the blade not making any contact
with the workpiece.
Switch on the tool and allow it to reach its full speed.
Align the saw blade with the cutting line on the workpiece, gently push the saw forward.
Never force the saw but maintain a light and continuous pressure when completing the cut. Switch off the
tool only after the tool is completely away from the workpiece When the cutting is interrupted, resume
the cut by allowing the blade to reach full speed and then reentering the cut slowly.
When cutting across the grain, the fibers of the wood will have a tendency to lift and tear, moving the
saw slowly to minimize this effect.
Note: there are two notches on the front edge of the shoe as an aid for alignment. When making a
45° bevel cut, just align the left notch marked with 45° with the cutting line on the workpiece. For a
straight 90° cut, align the right notch marked with 0° with the cutting line on the workpiece. For
precise cutting, always make a trial cut before carrying out operation.
Pocket cutting
Disconnect the plug from the power supply before making any adjustments. Set the depth adjustment
based on the thickness of the line drawing for the cut .raise the lower guard by using the lift lever.
With the blade barely above the material to be cut, start the saw and allow the blade to come to full
speed. Gradually lower the blade unto the material to be cut using the front end of the shoe as a pivot
point. When the blade starts cutting, release the lower guard. When the shoe is resting flat on the
surface being cut, proceed cutting in a forward direction to the end of the cut. Allow the blade to come
to a full stop before removing it from the cut. Never pull the saw backward since the blade will climb
out of the cut and kickback will occur. Turn the saw around and finish the cut in a normal manner,
sawing forward. Use a jigsaw or a hand saw to finish the cut in the corners, if required.

16
Cutting large sheets
Large sheet or boards require support to prevent bends or sags. If you attempt to cut without levelling
and properly supporting the work piece, the blade will tend to bind, causing kickback.
Support the panel or board close to the cut. Be sure to set the blade adjustment so that you can cut
through the material without cutting into the table or workbench.
Suggestion: use two by fours to support the board or panel to be cut. If the piece is too large for the
workbench, use the floor with the two-by fours supporting the wood.
Laser line generator
WARNING: Do not stare directly at the laser beam, do not deliberately aim the beam at
personnel
and ensure that it is not directed towards the eye of a person for longer than 0.25s.
When you make the line of the cut on the work piece, the laser line generator can help you get
better alignment.
The laser generator switch is located at the front of the safety lock button for the mechanical plunge stop.
Turn on: Press the laser generator switch to “I” position, the laser generator (1) works.
Turn off: Press the switch to “O”position.
1. Make sure line of the cut is on the work piece.
2. Adjust the depth of cut as required.
3. Plug in the machine and start the motor.
4. When the blade is at its maximum speed (approximately 5 seconds), place the saw on the work-piece.
5. Switch on the laser generator from the laser aperture using the laser generator switch.
6. Align the beam with the mark on the work-piece and slowly push the saw forward using both hands,
keeping the red-light beam on the mark.
7. Switch off the laser beam after completion of the cut.

17
MAINTENANCE
WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products,
penetrating
oils, etc., come in contact with plastic parts. Chemicals can damage, weaken or
destroy plastic which may result in serious personal injury.
Regular cleaning is required for the safe operation of the tool, as an excessive buildup of dust will prevent
the tool from operating correctly.
The dust extraction hose (B) may block and require cleaning occasionally, especially if damp wood is
being cut.
1. Unplug from mains supply.
2. Clean thoroughly with a small soft brush, like a paint brush.
3. Keep the cooling vents on the motor housing clean and unobstructed at all times.
4. Never use any caustic agents or solvents to clean the plastic parts.
Blade
• Always use a sharp blade.
• If the tool does not cut as well as expected or if it overheats (temperature cut out may trip) the most
common cause is a blunt blade.
• It is difficult to see or feel if the blade is blunt. When in doubt use a new blade.
• Blades are consumable items.
• Beware when changing blade as they can become hot during use. Allow the blade to cool before
replacing it.
Carbon brush
For safety reasons, the machine automatically switches off if the carbon brushes are so worn out that they
no longer have contact with the motor. In that case, the carbon brushes must be replaced by a pair similar
carbon brush available through the after-sales service organization or qualified professional person.
If they are 6 mm or less then they must both be replaced. Fit new carbon brushes and replace the brush
housing.
CAUTION: The brushes must always be replaced in pairs.
CAUTION: Always disconnect the machine from the power supply before removing any electrical
covers.
Changing the button batteries for Laser generator
Unplug the saw from power mains.
WARNING: Failure to unplug your tool could result in accidental starting causing possible
serious personal injury.
1. Open the battery cover located on the top of the motor by using a screwdriver.
2. Take out the old button batteries from battery holder and replace with new button batteries.
Dispose of old batteries properly.
3. Close the battery cover.
