The machine must not be used until the fault has been eliminated. - Cutting rebates or grooves is only permitted with a suitable protective device fitted, e.g. a protective tunnel over the saw table. - Do not use circular saws for cutting slots (grooves in workpiece). - Do not use the top protective cover as a handle for transportation! - Before transporting the machine, make sure that the top protective guard covers the top section of the saw blade. - Use a suitable device to support long workpieces and ensure that they are horizontal. - Make sure that there is adequate lighting in the room or workplace. - Operating personnel must have received adequate training in the use, set-up and operation of the machine. - 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. Emission levels Noise emissions have been measured in accordance with the specifications in EN 61029. These specifications apply for operation as a trimming saw and bench-mounted circular saw. Noise level Sound power level, idling 91 dB(A) Sound power level, during operation 103 dB(A) Measuring uncertainty allowance K = 3 dB Workplace emission levels Workplace emission, idling 77 dB(A) Workplace emission, during operation 90 dB(A) CAUTION The noise produced during work may damage your hearing. Wear ear protection! Measured acceleration < 2.5 m/s² 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. Other 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 emissions, wood dust emissions.

Commissioning WARNING Risk of accident if the machine is operated using unauthorised voltages or frequencies. The mains voltage and the frequency of the power source must correspond with the specifications on the machine’s name plate. In North America, only Festool machines with voltage specifications of 120 V may be used.

Assembling the machine Setting up the machine Ensure that the floor around the machine is level, in good condition and free of loose objects (e.g. chips and offcuts). L The machine can be set up with or without the legs unfolded. To unfold the legs: Unscrew the rotary knobs [1-12] all the way. Unfold the legs [1-1] and tighten the rotary knobs [1-12] again. If the machine wobbles, turn the end cap [1-9] on one leg to adjust the length so that the machine stands securely. Fitting the knob Screw the rotary knob [2-6] supplied anticlockwise into the guide rod. Fitting the protective cover Pull the spacer wedge [1-6] sharply upwards [7-2] to move to the top catch position. Secure the top protective cover supplied to the spacer wedge in this position using the rotary knob [1-11]. 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.

On/Off switch We recommend using a 16 A fuse because of the performance of the motor. To switch on: Press the green "On" switch [12]. The red button is the "Off" switch. L A switch-on lock is available as an accessory to prevent the machine from switching on unintentionally.

Machine settings WARNING Risk of accident, electric shock Always pull the plug out of the socket before performing any type of work on the machine. Electronics The machine features full-wave electronics with the following properties: Smooth start-up The electronically controlled smooth start-up function ensures that the machine starts up smoothly. Speed control You can regulate the rotational speed (CS 70 EB only) steplessly between 2000 and 4200 rpm using the adjusting wheel [2-1]. This enables you to optimise the cutting speed to suit the respective material. The preselected motor speed remains constant through electronic control. This ensures a uniform cutting speed even when under strain. Overload safety device The machine power supply is limited if the machine is overloaded to extremes. The power supply is interrupted permanently if the motor is blocked for a few moments. Switch the machine off and on again to reset. Temperature cut-out The machine power supply is limited and the speed reduced if the motor exceeds a certain temperature. The machine continues operating at reduced power to allow the ventilator to cool the motor quickly. The machine starts up again automatically once the motor has cooled sufficiently. Brake (CS 70 EB only) After the machine switches off, the saw blade is electronically brought to a standstill in 3 seconds.

Restart protection The integral undervoltage release prevents the machine from automatically starting up again after an interruption in power when the machine is used in continuous operating mode. The machine will have to be switched back on in this case. Set-up position Always move the saw to set-up position before making any adjustments: The saw is locked in rest position on delivery. Turn the rotary knob [2-6] anticlockwise to release the lock and pull the saw forwards. Push the stop lever [1-7]. The saw is locked in the front position. Adjusting the cutting depth Proceed as follows to adjust the cutting depth in set-up position to any setting between 0 70 mm: Turn the cutting depth adjuster [1-8]. L Set a cutting depth 2 - 5 mm greater than the thickness of the workpiece to produce a clean cut. Adjusting the mitre angle The saw blade can be tilted between 0° and 45° in set-up position: Unscrew the rotary knob [2-4]. Adjust the mitre angle using the rotary handle [2-3] with reference to the scale [2-5]. Tighten the rotary knob [2-4]. The saw blade can be tilted 2° beyond the two end positions for precision trimming work (undercuts on abutting edges). Press and hold the button [2-2] in the end position. The saw blade can now be tilted from -2° to 47° using the rotary handle [2-3]. Release the button [2-2] to reactivate the 0° and 45° stops.

Changing tools Removing saw blades Lock the saw in set-up position. Set the widest inclination angle and the maximum cutting depth. Loosen the clamp on the insert via the rotary knob [5-1]. Slide the clamping plate forwards. Reach underneath the table insert [1-4] from the back and remove by lifting away from the back of the table. Remove the protective cover. Swivel the cover [5-10] backwards. Remove the hexagon wrench [5-3] from the store on the base [5-6] and insert in the saw blade retaining screw. Press and hold the spindle stop [5-2] (behind the saw blade) and use the hexagon wrench to turn the saw shaft until the spindle stop [5-2] engages and the saw shaft locks. L The saw blade retaining screw has a lefthanded thread. Firmly turn the saw blade retaining screw clockwise and remove the clamping flange and the saw blade. Installing saw blades WARNING Risk of injury Observe the rotation direction when attaching a new saw blade: the rotation direction on the saw blade [5-4] must correspond with the rotation direction on the machine. Place the saw blade in position. Secure the saw blade and the flange to the saw shaft using the saw blade retaining screw. Close the cover [5-10] and fit the protective cover. Make sure that the cover [5-10] engages in the tabs [5-9]. Replace the hexagon wrench [5-3] back in the store. Fitting the table insert [1-4] in the table Insert the protruding spring plate [5-5] on the insert forwards into the table frame first. Make sure that the contact surface is free of dust. Lay the insert in position and secure with the clamp and the rotary knob [5-1]. Setting the spacer wedge Once the protective cover is removed, pull firmly on the spacer wedge [1-6] to move to one of two catch positions. The spacer wedge is used in the top catch position [7-2] in the all applications, except concealed cuts. For concealed cuts only Remove the top protective cover.

Press down the spacer wedge firmly to move to the lower catch position [7-1]. When producing concealed cuts, make sure you guide the machine accurately. Press the workpiece firmly onto the table. When cutting the workpiece, make sure that the side of the workpiece that is already cut out is not on the same side as the fence. After completing concealed cuts, move the spacer wedge [1-6] back to the top position and attach the protective cover (see chapter 6.1).

7.7 Fence

The fence can be attached at any point along the clamping edge of the saw base and is so versatile, it can be used as a cross stop [Fig. 1] or a longitudinal stop [Fig. 6]. L Before attaching, make sure that the contact surfaces of the fence are not dirty. WARNING Risk of injury Always use the fence in a fixed position and do not use to slide the workpiece along! Fitting the fence Open the clamping jaws using the knob [4-4]. Place the fence with guide rail [4-5] onto the clamp rail from above. Secure the clamp segment using the knob [44]. The fence can be adjusted in the following ways: Move the fence on the clamp segment Unscrew the rotary knob [1-5] and move the fence. Move the stop ruler Unscrew the rotary knob [4-1] and move the fence. L The stop ruler is stepped on one side by 8 mm. This guide rail can be used to guide the cross stop up to the saw cut to support the workpiece without having to remove the top protective cover. Adjust the angle Unscrew the rotary knob [4-2] and lift the retaining pin [4-3]. The rotary retaining pin engages at the most frequently used angle settings.

Adjust the position of the stop profile Unscrew the rotary knob [4-1]. Remove the guide rail [4-6] and turn 90°. Place the guide rail in the guide slot available. [Fig. 4] The dimensions of the aluminium profile provide a high guide surface for high workpieces and a low guide surface for flat workpieces. Longitudinal stop Position the stop ruler parallel to the blade to make rip cuts. Use the workpiece holder [6-1] for guiding narrow workpieces. The two rulers on the left and right of the saw blade cutting edges [7-1] are set to zero ex works so that the fence can be aligned with the scale along the front edge of the table. Fitting the splinterguard NOTE The splinterguard cannot be used when making bevel cuts. Remove the splinterguard as necessary. Unscrew the rotary knob [5-1]. Slide the clamping plate forwards. Lift the table insert [1-4] from the rear end and remove. Set the saw blade to the minimum cutting depth. Slide the splinterguard [8-3] up to the side of the retainer [8-1]. Place the table insert [1-4] in position and tighten the rotary knob [5-1]. Switch on the machine and move the saw blade slowly upwards to the maximum cutting depth. This beds in the splinterguard. The raised section [8-4] of the splinterguard should protrude slightly (approx. 0.3 mm) over the edge of the table so that the splinterguard functions more effectively. Unscrew both screws [8-2] to adjust the height of the retainer [8-1].

Dust extraction CAUTION Breathing in dust can damage the respiratory passage! Always connect the machine to a dust extractor. When performing work that generates dust, always wear a dust mask. The PRECISIO has two extraction connectors: top protective cover [3-7] 27 mm in diameter and the lower protective cover [3-3] 35 mm in diameter. Attach the hose holder [3-6] to the clamp rail on the saw base to guide the top suction hose. The extractor set CS 70 AB [3-4] (included in CS 70 EB scope of delivery) joins both extraction connectors so that a Festool mobile dust extractor with 50 mm adapter can be connected.

Working with the machine WARNING Risk of injury Always read all safety instructions when working with the machine! Never work with the machine in the front position (set-up position). Make sure that all rotary knobs on the fence and the machine are tightened before starting work. Adjust the top protective cover until it rests on the workpiece and secure in this position using the rotary knob [1-11].

Using the machine as a bench-mounted circular saw When used in bench-mounted applications, the saw is fixed and the workpiece is moved. Pull the saw forwards. Allow the saw to glide back slowly. You can push the stop lever [1-7] down after a few millimetres. If the saw continues to glide back, the stop lever engages in the guide rod and secures the saw at the centre of the table (bench saw position). Use the fence as a longitudinal stop [Fig. 6] to guide the workpiece. Guide the workpiece by hand. Use the workpiece holder [6-1] to guide the workpiece accurately past the saw blade. Place the workpiece holder in the store [2-7] when not in use. Using the machine as a trimming saw When the machine is used for trimming work, the workpiece remains stationary and the saw is moved to make the cut. Turn the rotary knob [2-6] anticlockwise to release the saw lock. Push down the stop lever [1-7] to unlock and move the saw to the forward position so that the control elements are easy accessible when the saw settings are adjusted. Turn the rotary knob [2-6] anticlockwise to release the lock again. Attach the cross or angle stop [Fig. 1] so that the workpiece is retained securely on the saw base. Alternatively, insert clamps (accessories) in the groove [1-10] to secure the workpiece. Use the rotary knob [2-6] to draw the saw forwards and make the cut. After completing the cut, move the saw unit right back to its starting position before removing the workpiece from the fence.

Service and maintenance WARNING Risk of accident, electric shock Always pull the plug from the mains power supply before maintaining, servicing or mak- ing any kind of adjustment. All maintenance and repair work which requires the motor housing to be opened, must only be carried out by an authorised service workshop. Damaged safety devices and parts should be repaired or replaced by an authorised service centre unless otherwise specified in the operating instructions. The machine is equipped with special self-disconnecting carbon brushes. If they are worn, the power is interrupted automatically and the machine comes to a standstill. Maintain your machine regularly to make sure it functions reliably: - Use an extractor to remove the dust deposits. - Keep the guide rods clean and grease regularly.

- Keep the toothed gears behind the rotary handle [2-3] clean. - Replace worn or damaged table inserts [1-4]. - If wood chips block up the extraction channel on the lower protective cover, unscrew the rotary knob [5-8] and move the flap [5-6] approx. 8 mm to open up a gap so that the blockage is removed. - If the blockage is serious or the saw seizes when the initial cut is made, unscrew the fasteners [5-7] using the hexagon wrench so that the flap [5-6] can be opened completely. Close the flap again prior to use. - After completing work, wind up the power cable onto the holder [1-3]. - A damper allows the saw unit to retract evenly along the entire cutting length. If this is not the case, the damper can be adjusted through the hole [3-5]. Filter cleaning (CS 70 EB only) You should clean the air intake filter [3-2] if the temperature monitor (see 7.1) triggers shutdown cycles more frequently without the machine being overloaded excessively. Unscrew the rotary knob [3-1]. Remove the filter insert. Knock off the dust or use an extractor on the surface of the filter. Insert the filter again. L If damaged, replace the filter with a new filter cartridge.
