SAFETY INSTRUCTIONS FOR TABLE SAWs GUARDING RELATED WARNINGS

Keep guards in place. Guards must be in working order and be properly mounted
A guard that is loose, damaged, or is not functioning correctly must be repaired or replaced. Always use saw blade guard and riving knife for every through-cutting operation.
For through- cutting operations where the saw blade cuts completely through the thickness of the workpiece, the guard and other safety devices help reduce the risk of injury.
Immediately reattach the guarding system after completing an operation (such as rebating or resawing cuts) which requires removal of the guard.
The guard and riving knife help to reduce the risk of injury. Make sure the saw blade is not contacting the guard, riving knife or the workpiece before the switch is turned on.
Inadvertent contact of these items with the saw blade could cause a hazardous condition. Adjust the riving knife as described in this instructior manual.
Incorrect spacing, positioning and alignment can make the riving knife ineffective in reducing the likelihood of kickback.
For the riving knife device to work, it must be engaged in the workpiece.
The riving knife is ineffective when cutting workpieces that are too short to be engaged with the riving knife.
Under these conditions a kickback cannot be prevented by the riving knife. Use the appropriate saw blade for the riving knife.
For the riving knife to function properly, the saw blade diameter must match the appropriate riving knife and the body of the saw blade must be thinner than the thickness of the riving knife and the cutting width of the saw blade must be wider than the thickness of the riving knife.

CUTTING PROCEDURES WARNINGS

Feed the workpiece into the saw blade only against the direction of rotation.
Feeding the workpiece in the same direction that the saw blade is rotating above the table may result in the workpiece, and your hand, being pulled into the saw blade.
Never use the mitre gauge to feed the workpiece when ripping and do not use the rip fence as a length stop when cross cutting with the mitre gauge.
Guiding the Workpiece With the rip fence and the mitre gauge at the same time increases the likelihood of saw blade binding and kickback
When ripping, always apply the workpiece feeding force between the fence and the saw blade.
Use a push stick when the distance between the fence and the saw blade is less than 150 mm, and use a push block when this distance is less than 50 mm.
“Work helping” devices will keep your hand at a safe distance from the saw blade. Use only the push stick provided by the manufacturer or constructed in accordance with the instructions.
This push stick provides sufficient distance of the hand from the saw blade. Never use a damaged or cut push stick.
A damaged push stick may break causing your hand to slip into the saw blade. Do not perform any operation “freehand'”.
Always use either the rip fence or the mitre gauge to position and guide the workpiece.
“Freehand” means using your hands to support or guide the workpiece, in lieu of a rip fence or mitre gauge.
Freehand sawing leads to misalignment, binding and kickback. Never reach around or over a rotating saw blade.
Reaching for a workpiece may lead to accidental contact with the moving saw blade.
Provide auxiliary workpiece support to the rear and/or sides of the saw table for long and/or wide workpieces to keep them level.
A long and/or wide workpiece has a tendency to pivot on the table’s edge, causing loss of control, saw blade binding and kickback. Feed workpiece at an even pace.
Do not bend or twist the workpiece. If jamming occurs, turn the product off immediately, unplug the product then clear the jam.
Jamming the saw blade by the workpiece can cause kickback or stall the motor. Do not remove pieces of cut-off material while the saw is running.
The material may become trapped between the fence or inside the saw blade guard and the saw blade pulling your fingers into the saw blade.
Turn the saw off and wait until the saw blade stops before removing material. Use an auxiliary fence in contact with the table top when ripping workpieces less than 2 mm thick.
A thin workpiece may wedge under the rip fence and create a kickback.

Warning

KICKBACK CAUSES AND RELATED WARNINGS

Kickback is a sudden reaction of the workpiece due to a pinched, jammed saw blade or misaligned line of cut in the workpiece with respect to the saw blade or when a part of the workpiece binds between the saw blade and the rip fence or other fixed object.
Most frequently during kickback, the workpiece is lifted from the table by the rear portion of the saw blade and is propelled towards 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.
Never stand directly in line with the saw blade. Always position your body on the same side of the saw blade as the fence.
Kickback may propel the workpiece at high velocity towards anyone standing in front and in line with the saw blade.
Never reach over or in back of the saw blade to pull or to support the workpiece.
Accidental contact with the saw blade may occur or kickback may drag your fingers into the saw blade.
Never hold and press the workpiece that is being cut off against the rotating saw blade.
Pressing the workpiece being cut off against the saw blade will create a binding condition and kickback. Align the fence to be parallel with the saw blade. A misaligned fence ill pinch the workpiece against the saw blade and create kickback.
Use a featherboard to guide the workpiece against the table and fence when making non-through cuts such as rebating or resawing cuts.
A featherboard helps to control the workpiece in the event of a kickback.
Support large panels to minimise the risk of saw blade pinching and kickback
Large panels tend to sag under their own weight. Support(s) must be placed under all portions of the panel overhanging the table top.
Use extra caution when cutting a Workpiece that is twisted, knotted, warped or does not have a straight edge to guide it with a mitre gauge or along the fence.
A warped, knotted, or twisted orkpiece is unstable and causes misalignment of the kerf with the saw blade, binding and kickback.
Never cut more than one workpiece, stacked vertically or horizontally. The saw blade could pick up one or more pieces and cause kickback.
When restarting the saw with the saw blade in the workpiece, centre the saw blade in the kerf so that the saw teeth are not engaged in the material.
If the saw blade binds, it may lift up the workpiece and cause kickback when the saw is restarted. Keep saw blades clean, sharp, and with sufficient set.
Never use warped saw blades or saw blades with cracked or broken teeth. Sharp and properly set saw blades minimise binding, staling and kickback.

TABLE SAW OPERATING PROCEDURE WARNINGs

Turn off the table saw and disconnect the power cord when removing the table insert, changing the saw blade or making adjustments to the riving knife or saw blade guard, and when the machine is left unattended. Precautionary measures will avoid accidents.
Never leave the table saw running unattended.
Turn it off and don’t leave the product until it comes to a complete stop. An unattended running saw is an uncontrolled hazard.

ADDITIONAL SAFETY WARNINGS FOR TABLE SAWS

Setup or fix the machine in a stable position appropriate for the work being done.
This could be mounted on a Workbench, leg support or fixed to the floor. If fitted, set the adjustable leg extension to achieve a level stable platform to work on.
Working at the proper height, using good working posture, will help prevent strain or other injuries during operation.
Provide adequate general or localised lighting to prevent stroboscopic effect and hazards.
Wear suitable personal protective equipment when necessary.
This includes hearing protection to reduce the risk of hearing loss, respiratory protection to reduce the risk of inhaling harmful dust, sturdy gloves when handling saw blades and rough material.
Always wear safety goggles when using the machine.
It is recommended to wear sturdy non slipping shoes with toe caps to protect from objects faling from the table.
The dust produced when using this tool may be harmful to your health, inflammable or explosive.
Do not inhale the dust. Use a dust extraction system and wear a suitable dust protection mask.
Remove deposited dust thoroughly, e.g., with a brush and vacuum cleaner.
Keep the floor in the working area free from excessive sawdust, cut-offs and power cables.
This reduces the risk of tripping and falling onto the blade.
Keep the table clear of objects including tools and discarded wood cut-offs. Keep the surface of the table, fence and mitre guide clean.
Beware of glue, paint and other items. The wood must slide smoothly and not catch or snag anywhere otherwise the risk of severe injury due to kickback is significantly increased.
Use only blades specified in this manual, complying With EN 847-1.
Do not use saw blades made of high-speed steel. Use only saw blades that are marked with a speed equal or higher than the speed marked on the tool.
Do not force the work piece into the cutting blade. Let the tool do the work.
Excessive force will overheat the blade and cutting tips, it may burn the work piece
It may result in unexpected events which could cause serious personal injury.
Do not use dull or damaged blades. Unsharpened or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.
Never use blade washers or bots that are defective or incorrect. Saw blades should be carried in a holder whenever possible.

SPECIFIC SAFETY INSTRUCTIONS FOR WOOOD CUTTING BLADE

Please read the manual and instructions carefully before using the saw blade and the power tool.
The power tool must be in good condition, the spindle without deformation and vibration.
Ensure the operator is adequately trained in safety precautions, adjustment and operation of the power tool.
Always wear goggles and ear protection the power tool. It is recommended to wear gloves, sturdy non slipping shoes and apron us
Before using any accessory, consult the instruction manual.
The improper use of an accessory can cause damage and increase the potential for injury. Keep the blade clean.
This includes saw dust and particularly sticky substances like wood resin. A clean blade cuts more accurately and safely.
Use only blades specified in this manual, complyingg with EN 847-1. Observe the maximum speed marked on the saw blade
Ensure the speed marked on the saw blade is at least equal to the speed marked on the saw. Always use blades with correct size and shape of arbor holes.
Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
Do not use saw blades with a body thickness greater or a width of the groove cut (kerf) smaller than the thickness of the riving knife.
Do not use blades of larger or smaller diameter than recommended. Do not use any loose washers or spacers to make the blade fit onto the spindle.

OPERATION

Through cutting: Any cutting operation where the saw blade protrudes beyond the thickness of the workpiece.
For this operation the riving knife should be in the raised position and the blade guard must be fitted. Use a fence or mitre guide to correctly position the workpiece.
Non through cutting: Any cutting operation where the saw blade does not protrude beyond the thickness of the workpiece.
For this operation the riving knife should be in its lowered position. The top of the riving knife should be slightly lower than the top of the saw blade. The blade guard cannot be fitted.
Use a fence or mitre guide to correctly position the workpiece. Rip cutting: Using the rip fence parallel to the blade to guide the workpiece.
Predominantly the cut is made in the direction of the wood grain (ff present). Can be a through or non through cut. Cross cutting: Using the mitre guide or cross cutting fence.
This device is designed to slide parallel to the saw blade and enables the workpiece to be held at a fixed angle across the cutting axis of the blade.
Predominantly the cut Is made across the direction oft the wood grain (it present). Can be a through or non through cut. Bevel cutting: The angle of the blade with respect to the table surface is changed between 90 and 45°.
Produces a cut with an angled edge. Can be a through or non through cut.
Either the rip fence or the mitre guide should be used to correctly position the workpiece.

Mitre cutting: The workpiece is presented to the blade at an angle. The angle required is set on the mitre guide, which can then hold the workpiece at this angle whilst sliding parallel to the blade to make the cut. Can be a through or non through cut.

Tapered cutting: Tapered cross cuts are possible using the mitre guide set to the angle required. It is not possible to perform tapered rip cuť’s as a special fixture is required.

USING THE FENCE SAFELY

Never use the rip fence and the mitre angle guide at the same time
This increases the potential for kickback and personal injury.
When either is not in use, remove it from the table and store safely out of the way.
Each time the fence is used or moved to another position it is essential that it is checked for parallelism to the saw blade.
A non parallel fence can trap the workpiece between the blade and the fence causing kickback which can lead to severe personal injury to yourseir and otners.
A badly adjusted or set fence can cause the workpiece to be fed toward the blade at the wrong angle which may cause the blade to bind or jam.
It can also cause kickback (see above). To fit or adjust the fence properly, hook the end of the fence over the back edge of the table then lower the front edge to engage with the front of the table.
Then apply pressure from the front of the fence so that the TWO edges set at a right angle to the direction Or the fence contact the front edge of the table.
This helps ensure the fence is parallel to the blade. Then lock the fence in position by pushing the locking handle downwards.
The force by which the locking handle holds the fence in position can be adjusted by rotating the knurled Screw just above the locking handle.
Always check the parallelism of the fence to the blade by measurement or by an accurately cut block of wood before making the cut

OVERLOAD PROTECTION DEVICE

The product has an overload protection device.
When overloading is detected, the product will automatically switch off.
Turn the power off. If the overload protector is actuated, the motor must be allowed to cool down for 3 minutes.
Make sure the blade can rotate freely and is not jammed or tight. Press the reset button (below the on/off switch).
Turn the power on. Press the on button to start the product.

MAINTENANCE

Ensure the saw blade is completely stopped and the power cord is removed from the power source before conducting any maintenance or cleaning. lf the power supply cord is damaged it must be repaired at an authorised service centre. The blade has sharp edges and may also remain hot after cuting operations. Exercise extreme caution when cleaning an exposed blade. Wear gloves to protect yourself from personal injury. Clean the saw and its accessories from dust regularly, especially moving parts including the blade guard. Use a hand brush or vacuum cleaner to remove dust effectively.

CHECKING AND SETTING THE BEVEL ANGLLE NOTE

Setting the blade to be 90° from the table results in a 0° bevel angle.
Turn off the power and remove the plug from the wall SOcket.
Pay particular attention to the saw blade tips, they are very sharp and can cause personal injury.
Raise the blade and riving knife assembly to its highest height.
Remove the blade guard.
Place the riving knife to its lower position. 6. Ensure the blade and table surface are clear of dust and debris.
Place a 90 “set square” against the table surface and the highest part of the blade. Be careful not to contact the blade tips during this measurement as it will result in an error. You need to align the body Surtace of the saw blade.
There should be no gaps between the edge of the set square and the blade or the table, the blade is in a true vertical alignment and no further adjustment of the blade angle is necessary.
If a gap exists, loosen the bevel locking knob and carefully move the angle of the bevel whilst constantly re-checking the gap. Once no gap exists, tighten the bevel locking knob securely.
Loosen the screw on the bevel angle indicator and adjust the clear plastic line carrier so it shows alignment with the O mark. Tighten the screw.
Repeat this operation to check and set various angles between 90° and 45° as you feel necessary. his condition
