your hearing

• Protective goggles
• Face mask to reduce the risk of inhaling harmful dust
• Protective gloves when handling tools and coarse materials
• To minimise the creation of dust, the machine is to be connected to a suitable dust extractor, and all the elements for dust collection (extractor hood etc.) must be properly set.
• When sawing wood, the machine is to be connected to a dust extractor complying with EN 60335-2-69, dust category M.
• To minimise noise development, the tool must be sharpened and all elements for noise reduction (covers etc.) must be properly set.
• The machine may only be used if all protection devices are in the appropriate positions and if the machine is in good condition and has been properly serviced.
• Faults in the machine, including the separating protection devices or in the tools, must be reported immediately on discovery to maintenance personnel. The machine may only be used again once the faults have been rectified.
• Rebating or grooving are only permitted with a suitable protection device, e.g. a tunnel protection device over the saw table.
• Circular saws must not be used for slotting (groove completed in the workpiece).
• The upper protective hood may not be used as a carrying handle!
• During transport of the machine, the upper protective cover must cover the upper section of the saw blade.
• Long workpieces are to be supported by a suitable setup so that they lie horizontally.

• Always assume the correct position before starting work:

• front at the operating end,
  -facing the machine,

• next to the cutting line.

• Never process material containing asbestos.

• Do not remove offcuts or other workpiece parts from the cutting area while the tool is still running and until the saw blade stops.
• If the saw blade is blocked, switch the machine off immediately and disconnect the mains plug. Do not remove the jammed workpiece until you have done this.

3.3 Noise and vibration information

Sound pressure level

ldling / processing 84/90 dB(A)

Noise power level

Idling / processing 97 / 103 dB(A)

Measurement tolerance K = 3dB

Wear ear protection!

Measured acceleration < 2.5 m/s^2

The emission values specified (vibration, noise) were measured in accordance with the test conditions stipulated in EN 61029 and are intended for machine comparisons. They are also used for making preliminary estimates regarding vibration and noise loads during operation.

The emission values specified refer to the main applications for which the power tool is used. If the electric power tool is used for other applications, with other tools or is not maintained sufficiently prior to operation, however, the vibration and noise load may be higher when the tool is used. Take into account any machine idling times and downtimes to estimate these values more accurately for a specified time period. This may significantly reduce the load during the machine operating period.

3.4 Residual risks

In spite of compliance with all relevant design regulations, dangers may still present themselves when the machine is operated, e.g.:

• Workpiece parts being thrown off,
• Parts of damaged tools being thrown off,
• Noise emission,
• Sawdust emission.

4 Setting up, commissioning

Ensure that the floor around the machine is level, in good condition and free of loose objects (e.g. chips and offcuts).

4.1 Mounting the machine

The machine can be set up with or without the legs folded out (Fig. 1 and 2) (the „Floor“ model does not include folding legs).

To fold out the legs, open the four rotary knobs (1.6) as far as they will go. After folding out the legs, retighten the four rotary knobs.

So that the machine stands securely, the length of one of the legs can be changed by turning the cap on the end (1.7).

4.2 Transport

• Engage the saw unit in the zero position.
• Remove all attachments from your saw and wind up the cable on the cable holder.
• Fold up the legs.

4.3 Applications

The machine can be used as a bench-mounted circular saw or as a circular trimming saw.

a) Bench-mounted circular saw (Fig. 1)

• Set the switch (1.9) to the lower position.
• Swing the hand grip (1.8) downwards, and use the hand grip to pull the saw unit forwards until it locks into place.

The saw unit is now in a central bench position and the machine can be used as a bench-mounted circular saw.

b) Circular trimming saw (Fig. 3)

• Set the switch (3.10) to the upper position.

If the hand grip (3.9) is swung downwards, it can be used to move the saw unit backwards and forwards for drawing cuts. The backward movement is supported by spring force.

4.4 Dust extraction

The PRECISIO has two extraction connections: the upper protective cover (2.3) with a diameter of 27mm , and the lower protective cover (2.2) with a diameter of 35mm .

The extraction set CS 70 AB (488292, included in scope of delivery for CS 50 EB) joins both of the extraction connections so that a Festool extractor module can be connected.

4.5 Power supply and start-up

The mains voltage must correspond to the specification on the rating plate.

In North America, only Festool machines with the voltage specifications 120 V/60 Hz may be used.

On account of the performance capability of the motor, we recommend a 16 A fuse.

To switch on, press the ON/OFF switch (4.1) and the locking switch (4.4) simultaneously. The machine runs as long as the ON/OFF switch is pressed.

For continuous operation after switching on, first press the ON/OFF switch (4.1) and then let go of the locking switch (4.4). To switch off continuous operation, either press the ON/OFF switch again

and let it go or press the red switch (4.6). To protect against unauthorised activation, a shackle type connector can be inserted in the hole (4.2) of the ON/OFF switch.

5 Electronics

The machine has full-wave electronics with the following features:

5.1 Smooth start-up

The smooth start-up ensures the machine starts up jolt-free.

5.2 Speed adjustment

You can regulate the speed stepplessly between 1600 and 4200rpm using the adjusting wheel (4.5). This enables you to optimise the cutting speed to suit the material (4.3).

The pre-selected speed remains constant whether the machine is in operation or in neutral position.

5.3 Overload protection

In the event of an extreme overload of the machine, the power supply is reduced. If the motor is blocked for a longer period, the power supply is interrupted completely. After removal of the blockage or switching on again, the machine is operational once again.

5.4 Temperature protection

If the motor temperature becomes too high, the power supply and speed are reduced. The machine then only runs with reduced power to enable rapid cooling by means of the motor ventilation. After cooling down, the machine accelerates again automatically.

5.5 Brake

After switching-off the tool, the saw blade is electronically brought to a standstill in 1.5 - 2 seconds (only for 230V - 240V configuration).

5.6 Restart protection

The built-in undervoltage release prevents that the machine restarts on its own in the continuous operation mode following a power cut. In this case, the machine must first be switched off and then on again.

6 Machine settings

Prior to any setting, maintenance or repair, pull the mains plug!

To make setting easier, the saw unit can be locked in the front position (Fig. 5): pull the saw unit forwards as far as it will go and place the switch (5.1) in the lower position.

The machine must not be used in the front position!

6.1 Cutting depth

The cutting depth can be set stepplessly (0 - 50 mm with 90^ position of the saw blade) by turning the crank handle (5.4).

6.2 Mitre

The saw blade can be pivoted between 0^ and 45^ :

• Open the rotary knob (5.3).
• Set the litre using the scale (5.6) by turning the handle (5.2).
• Close the rotary knob (5.3).

For exact fitting work (relief cutting on the bordering), the saw blade can be pivoted 2^ beyond the two end positions. To do so, the button (5.5) is pressed in the end position; the saw blade can then be pivoted up to -2^ or 47^ . On pivoting back, both end positions are active once again.

6.3 Changing tools

Safety Instructions Fast-Fix Tension Nut (see Fig. 7 A).

After tensioning, close the handle bow.

Only tighten or loosen the Fast-Fix Tension Nut by hand. Under no circumstances use the handle bow with aid of screwdrivers, pliers, or other tools for tightening or loosening.

If the nut cannot be loosened by hand, only use a pin-type face spanner for support.

Never continue to use the Fast-Fix nut, in case the handle bow is loose or damaged.

Due to the special shank, only the saw blades offered by Festool for this machine may be used.

• Open the locking mechanism (1.3) and remove the bench insert (1.2) upwards
• Open the locking mechanism (6.1) and swing the saw blade cover (6.2) down. This automatically locks the tool spindle
• Shift the lever (7.5) and turn clockwise (left-hand thread) to open the Fast-Fix clamp (7.4)

• Change the tool. In doing so, bear in mind:

• The Fast-Fix clamp (7.4), flange (8.1) and saw blade must be clean

• The direction of rotation on the saw blade (7.6) must match the direction of rotation of the machine (7.7)

• Place the saw blade on the centre of the flange (8.1) and turn until the contour of the flange and the saw blade hole lock.
• Firmly tighten the Fast-Fix clamp (7.4) anticlockwise; shift the lever (7.5)
• Swing the saw blade cover (6.2) upwards and close the locking mechanism (6.1)
• Insert the bench insert with the rear edge first (see Fig. 9) and close the locking mechanism (1.3).

6.4 Setting the riving knife

The spacer wedge (7.1) is to be set in such a way that the gap to the chuck of the saw blade is 3 to 5 ~mm .

• Use the Allen key (6.3) to remove the screw (7.3) and take it out together with the clamping element (7.2),
• After both of the screws (8.3) have been opened, the guide element (8.2) can be shifted vertically to set the gap between the spacer wedge and saw blade.
• After completion of the setting, fit the spacer wedge and clamping element again and tighten all screws.

6.5 Guide

As shown in Fig. 3, the supplied guide can be secured to all four sides of the machine. The guide offers the following adjustment options:

• Adjustment parallel to the bench edge - open the rotary knob (3.5).
• Adjustment vertical to the bench edge - open the rotary knob (3.6).
• Adjustment of the sliding fence (3.1) in a longitudinal direction - open the rotary knob (3.2). The sliding fence can be clamped onto the holder in a low position for thin workpieces (Fig. 1), or in a high position for thick workpieces (Fig. 3).
• Angle adjustment using the scale (3.7) - open the rotary knob (3.3) and raise the fixing pin (3.4). The rotating fixing pin locks into place in the most common angle positions.

This means that the guide can be used as a parallel guide (Fig. 1) or as a cross guide or angle guide (Fig. 3).

Prior to all work, make sure that all rotary knobs of the guide are tightened. The guide may only be used in a fixed position and not to shift the workpiece.

6.6 Scale for cutting width

The two scales (1.5) specify the cutting width for longitudinal cuts.

If required, the scales can be realigned after opening the screws (1.4).

6.7 Mounting the splinterguard

The splinterguard (10.2) prevents breakouts on the lower cutting edge of the workpiece.

The splinterguard can be used for all mitres, but a separate splinterguard must be fitted and sawn in for each angle:

• Set saw blade to minimum cutting depth.
• Open the locking mechanism (1.3) and remove the bench insert (1.2) upwards.
• Open the locking mechanism (6.1) and swing the saw blade cover (6.2) down. This automatically locks the tool spindle.
• Push splinterguard (10.2) from the side into the holder (10.3) up to the stop.
• Swing the saw blade cover (6.2) upwards and close the locking mechanism (6.1).
• Insert the bench insert with the rear edge first (see Fig. 9) and close the locking mechanism (1.3).
• Switch on tool and slowly move the saw blade up to the maximum cutting depth – this cuts the splinterguard to shape.

For a optimum function the raised part (10.1) of the splinterguard should protrude slightly (approx. 0.3 mm ) above the surface of the base runner. For this purpose the height of the holder (10.3) can be adjusted after releasing both screws (10.4).

7 Working with the machine

When working with the machine, comply with all safety instructions.

Adjust the protective hood so that it rests on the workpiece and clamp it in this position with the knob (1.1).

7.1 Bench-mounted circular saw

Use the guide as a parallel guide (Fig. 1) to guide the workpiece. The cutting width can be set using the scales (1.5). Guide the workpiece into place by hand. Use the workpiece holder (2.4) to guide the workpiece safety past the saw blade. When not in use, place the work-piece holder in the storage compartment (2.1).

7.2 Circular trimming saw

Use the guide as a cross guide or as an angle guide (Fig. 3) to apply and secure the work-piece. Alternatively, clamps (489570) can be inserted in the grooves (3.8) to secure the workpiece. Perform the sawing cut by swinging the hand grip (3.9) downwards and using the hand grip to pull the saw unit forwards. After making the sawing cut, move the saw unit right back again into its initial position before you take the workpiece from the guide.

8 Maintenance and care

Prior to any setting, maintenance or repair, pull the mains plug!

All maintenance and repair work which requires the motor casing to be opened may only be carried out by an authorised service centre.

Damaged safety devices and parts should be repaired or replaced by an authorised service centre unless otherwise specified in the operating instructions.

The routers are fitted with special carbon brushes with automatic-switch-off. When the brushes reach their wear limit the current is interrupted automatically and the router comes to a standstill.

Service your machine regularly to ensure that it functions properly:

• Vacuum off dust deposits
• Keep the guide bars (1.10) clean and grease them regularly
• A worn or damaged bench insert is to be replaced
• The slider (11.1) can be used to open the hatch (11.3) to enable removal of cutting residues from the lower protective cover. In order to remove larger deposits, the hatch can be opened completely by removing the screw (11.2). Prior to commissioning, the hatch must be closed again!
• On completion of your work, wind the power cable around the holders (2.1).
• A damper means that the saw unit runs back evenly across the entire drawing length. If this is not the case, the damper can be adjusted through the hole (2.5).
