2 Safety warnings

2.1 General power tool safety warnings

WARNING! Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

2.2 Safety instructions for table saws

1) 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.
• After completing a non-through cut such as rabbeting, resawing, or dadoing, re-store the riving knife to the extended-up position. With the riving knife in the extended-up position, reattach the blade 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 instruction manual. Incorrect spacing, positioning and alignment can make the riving knife ineffective in reducing the likelihood of kickback.
• For the spacer wedge to be effective, it must be located in the sawing gap. For cuts in workpieces that are too short to allow the spacer wedge to engage, the spacer wedge is rendered ineffective. Under these conditions, a kickback cannot be prevented by the spacer wedge.
• 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.

2) Cutting procedures warnings

• DANGBR: Never place your fingers or hands in the vicinity or in line with the saw blade. A moment of inattention or a slip could direct your hand towards the saw blade and result in serious personal injury.
• 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 keep the workpiece in full contact with the fence and 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 accord-

ance 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 or cut 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 kick-back.
• Feed the workpiece evenly. Do not bend, twist or move the workpiece to the side. If the saw blade jams, switch the power tool off immediately, disconnect the mains plug and rectify the cause of the jam. The jamming of the saw blade by the workpiece can lead to kickbacks or engine jams.
• 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.

3) Kickback causes and related warnings

Kickback is a sudden reaction of the workpiece due to a pinched, jammed saw blade or mis-aligned 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

English

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 will 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 rabbeting, dado-ing or resawing cuts. A featherboard helps to control the workpiece in the event of a kickback.

- Use extra caution when making a cut into blind areas of assembled workpieces. The protruding saw blade may cut objects that can cause 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 workpiece is unstable and causes misalignment of the kerf with the saw blade, binding and kick-back.

- 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, stalling and kick-back.

4) Table saw operating procedure warnings

- Turn off the table saw and disconnect the battery pack 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 tool until it comes to a complete stop. An unattended running saw is an uncontrolled hazard.

- Locate the table saw in a well-lit and level area where you can maintain good footing and balance. It should be installed in an area that provides enough room to easily handle the size of your workpiece. Cramped, dark areas, and uneven slippery floors invite accidents.

- Frequently clean and remove sawdust from under the saw table and/or the dust collection device. Accumulated sawdust is combustible and may self-ignite.

- The table saw must be secured. A table saw that is not properly secured may move or tip over.

- Remove tools, wood scraps, etc. from the table before the table saw is turned on. Distraction or a potential jam can be dangerous.

- Always use saw blades with correct size and shape (diamond versus round) of ar-bour holes. Saw blades that do not match the mounting hardware of the saw will run off-centre, causing loss of control.

- Never use damaged or incorrect saw blade mounting means such as flanges, saw blade washers, bolts or nuts. These mounting means were specially designed

for your saw, for safe operation and optimum performance.

• Never stand on the table saw, do not use it as a stepping stool. Serious injury could occur if the tool is tipped or if the cutting tool is accidentally contacted.
• Make sure that the saw blade is installed to rotate in the proper direction. Do not use grinding wheels, wire brushes, or abrasive wheels on a table saw. Improper saw blade installation or use of accessories not recommended may cause serious injury.

Set the spacer wedge [7-3] so that the distance to the saw blade's sprocket is 3–5 mm.

▶ Use the hex key [6-6] to unscrew the screw [7-1] and remove it together with the clamping element [7-2] .
▶ After unscrewing both screws [8-2], the guide piece [8-1] can be moved vertically to adjust the distance between the spacer wedge and saw blade.
▶ After performing the adjustment, refit the spacer wedge and clamping element and retighten all the screws.

7.6 Adjusting the stop [1] [3]

The supplied stop can be attached to all four sides of the power tool. The fence can be adjusted in the following ways: The fence can be used as a stopper or as a cross stop or angle stop.

Stopper:

▶ Loosen the screw [3-4] and lift the fixing pin [3-3], adjust the angle to 0^ with the help of the scale, lock the fixing pin again and tighten the screw.
▶ Loosen the screw [3-5] and adjust the rail [3-6] in such a way that the triangular arrow lies within the green sticker, see details [1-8]. Then tighten the screw.
▶ Push the preset profile setting rail into the groove on the side of the table ([3] detail). Slide it until the preset profile setting rail's handle covers the green marked area on the side of the table, see detail [1-9]. Then tighten the screw [3-2].
▶ Loosen the screw [3-1], set the desired cutting width and retighten the screw.

The preset profile setting rail can be used as a high or low stopper. To do this, the rail is inserted either upright or flat.

The low stopper is used to prevent a collision with the saw blade protective cover, e.g. in the case of mitre cuts with a saw blade swivelled to 45^ .

Cross stop and angle stop:

▶ Slide the preset profile setting rail into the groove in the table and tighten the screw [3-2].
▶ Loosen the screw [3-4] and lift the fixing pin, adjust to the desired angle on the scale (the fixing pin will click into place in the most common angle settings) and then re-tighten the screw.
▶ Loosen the screw [3-5] and adjust the rail so that it does not reach into the cutting plane, and then tighten the screw.

Make sure that all rotary knobs on the workpiece are tightened before starting work. The should always be used in a fixed position must not be used to push the workpiece.

Fold the preset profile setting rail into the zero position and place it in the accessory holder [2-6] when not in use [2].

7.7 Scale for cutting width

The two scales [1-3] indicate the cutting width of rip cuts.

If needed, the scales can be readjusted after loosening the screws [1-4].

7.8 Installing the splinter guard

The splinter guard [10-2] prevents splinters on the lower cutting edge of the workpiece. The splinter guard can be used at all mitre angles, but a separate splinter guard must be installed and cut into for each angle:

▶ Set the saw blade to the minimum cutting height.
▶ Open the lock [1-5] and remove the table insert [1-6] upwards.
▶ Open the lock [6-8] and swivel the saw blade cover [6-7] downwards. This automatically locks the tool spindle
▶ Push the splinter guard onto the side of the retainer [10-3] as far as it will go.
▶ Swivel the saw blade cover upwards and close the lock.
▶ Insert the table insert with the rear edge [9] first and close the lock.
- Switch on the power tool and slowly move the saw blade up to the maximum cutting height – this cuts into the splinter guard.

The raised section [10-1] of the splinter guard should protrude slightly (by approx. 0.3 mm) over the edge of the table so that it functions more effectively. The height of the retainer can also be adjusted after loosening the two screws [10-4] .

7.9 Adjusting the protective cover

To adjust the stops, the protective cover can be locked in place in the upper position.

• Lock the lateral splinter guard [16-3] with the catch [16-2] in the upper position.
  ▶ Lift the protective cover into the top position [16-4] and tighten the screw [16-1]
  ▶ After adjusting the stops, loosen the screw again and unhook the side splinter guard. Note: The protective cover and the splinter guard must lie freely on the plate [17].
• When not in use, attach the protective cover to the accessory holder [2-6].

7.10 Smooth start-up
