Failure to follow all instruc- tions listed below may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future ref- erence. The term "power tool" in the warnings refers toyour mains-operated (corded) power tool or battery-op- erated (cordless) power tool.

2.2 Machine-related safety instructions

Dust that is harmful to your health may be pro- duced as you work (e.g. paint products contain- ing lead and some types of wood). Contact with or inhalation of this dust may pose a risk for the operating personnel or persons in the vicinity. Observe the safety regulations that apply in your country. Wear a P2 respiratory mask to protect your health. In enclosed spaces, ensure that there is sufficient ventilation and connect an extraction system. Always wear protective goggles to protect against sanding hazards.

Clean work equipment soaked in oils, for exam- ple sanding pad or polishing felt, with water and allow to dry. Work equipment soaked in oil may combust spontaneously.

Attention: Risk of fire! Avoid overheating the grinding material and the sander. Always empty the dust container before taking a break. Swarf in the filter bag or filter of the mobile dust ex- tractor may self-ignite in unfavourable condi- tions such as flying sparks when grinding metals. Particular danger exists if the swarf is mixed with paint, polyurethane residue or other chemical materials and the grinding material is hot after long periods of work.

If the power tool is dropped or falls, check for damage to the machine and sanding pad. Re- move the sanding pad for closer inspection. Have the damaged parts repaired before use. Broken sanding pads and damaged ma- chines can cause injuries and machine instabili- ty.

While using the long-life dust bag be aware of electric charge. Always when possible use an antistatic suction hose with the power tool.

slight electric shock may cause you to panic briefly and become distracted, which may result in an accident. – Only use the mains adapter with this device. – Only use the mains adapter together with an original Festool plug-it cable.

Only for AS/NZS: The tool shall always be sup- plied via residual current device with a rated re- sidual current of 30 mA or less.

Typically, the noise levels that are determined in ac- cordance with EN 62841 (see EC declaration of con- formity) are as follows: Vibration emission value a

(vector sum for three directions) and uncertainty K measured in accor- dance with EN 62841 (see EU Declaration of Con- formity): The specified emission values (vibration, noise) – are used to compare machines. – They are also used for making preliminary esti- mates regarding vibration and noise loads during operation. – They represent the primary applications of the power tool. Increase possible for other applications, with other insertion tools or if not maintained adequately. Take note of idling and downtimes of machine! 3 Intended use The sanders are designed for sanding wood, plas- tic, composites, paint/varnish, filler and similar materials as directed. Metals and materials that contain asbestos must not be processed. To guarantee electrical safety, the machine must not be damp or operated in a damp environment.

The switch [1-1] is an on/off switch (I = ON, 0 = OFF).

When the battery is empty, or if there is a power failure or the mains plug is removed, move the on/off switch immediately to the Off position. This prevents uncontrolled restarting.

Inserting the battery pack [2a]

Removing the battery pack [2b] Capacity display Pressing the green button on the capacity display [1-3] shows the charge status of the battery pack:

The mains adapter (available as an accessory de- pending on the model) facilitates use of the cord- less sanding technology with mains power, en- abling you to switch between power supply sources. The mains adapter enables the mobile dust ex- tractor's automatic electronic switch-on/shut-off function.

Connect the mains adapter and plug-it cable [3b]

Remove the mains adapter [3c]

Detach the mains adapter from the plug-it cable [3d] 7 Settings

Smooth start-up The electronically controlled smooth start-up en- sures that the machine starts up jolt-free. Temperature cut-out To avoid the motor overheating, the power con- sumption is limited at an excessive motor tempera- ture. If the temperature continues to rise, the pow- er tool switches off and can only be switched on again once the motor has cooled sufficiently. Constant speed The preselected motor speed is kept constant through electronic control. This means that, if the machine is used as intended (reasonable contact pressure), a constant sanding speed is achieved. Setting and adjusting the speed The speed can be set [1-5] between 6000 and 10000 min

using the adjusting wheel. For sanding, we recommend the following settings for the adjusting wheel [1-5]

< 15% Recommendation: Charge battery pack before further use. WARNING Unauthorised voltage or frequency! Risk of accident

The mains voltage and the frequency of the pow- er source must correspond with the specifica- tions on the machine's name plate.

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

When working on power tools, always remove the batteries or disconnect the mains adapter first.16 DTSC 400 Li, RTSC 400 Li

7.2 Changing sanding pad [4a]

An optimal work result can only be achieved using original accessories and consumables. The use of non-original accessories or con- sumables invalidates the right to claim under war- ranty. If the StickFix coating on the sanding pad has worn out, the entire sanding pad can be replaced: Undo the four screws. Remove the sanding pad by pulling it down- wards. Attach the new sanding pad. Use four screws to tighten it by hand (2.5 Nm).

7.3 Attaching sanding accessories using

StickFix [4b] The suitable StickFix sandpaper and StickFix sand- ing cloth can be attached quickly and simply to the StickFix sanding pad.

Affix the self-adhesive sanding accessory to the sanding pad.

Integral dust extractor with long-life dust bag As standard, the sanders are equipped with an inte- gral dust extractor. The sanding dust is extracted through extraction openings in the sanding pad and is collected in the dust bag. Installing the dust bag [5] Slide the dust bag onto the machine until it clicks into place. If the suction power is decreasing, empty the dust bag. Press the dust bag onto the actuating elements. Remove the dust bag by moving it towards the rear. Open the flap on the dust bag. Empty the dust bag and dispose of the waste. Dust extraction with Festool's mobile dust ex- tractor To prevent having to frequently empty the dust bag when carrying out sanding work for a long period of time, you can connect Festool's mobile dust ex- tractor (with an extraction hose diameter of 27 mm) to the extractor connection piece [1-4]

The start-up mode switches the mobile dust ex- tractor on as soon as you switch the orbital sander on. The start-up mode only works in conjunction with the mains adapter. Recommendation: Use an antistatic suction hose. This helps reduce the electric charge.

7.5 Edge protector [6]

The edge protector [1-7] prevents the sanding pad circumference from coming into contact with a sur- face (e.g. when sanding along a wall or a window), thus preventing back-kick of the machine, or ma- chine damage. Push the edge protector into the groove on the machine. Slot the two ends of the edge protector into place until they click.

Dust can be hazardous to health. Always work with a dust extractor.

Always read applicable national regulations be- fore extracting hazardous dust.DTSC 400 Li, RTSC 400 Li

Loosen both ends of the edge protector. Remove the edge protector by pulling it for- wards. 8 Working with the machine Observe the following instructions: – Do not overload the machine by pressing with ex- cessive force! The best sanding results are achieved with moderate application pressure. The sanding capacity and quality are mainly de- pendent on the selection of the correct abrasive. – Work in corners and on edges tends to subject the tip to increased stress and results in in- creased heat development. In such cases, work with reduced contact pressure. – Hold the machine with one hand on the handle [1-8]

The machine shuts down and makes a sound:

Switch off the machine. Battery pack is empty.

Change the battery pack. The machine shuts down and does not make a sound: Machine is overheated or has been overloaded.

Switch off the machine for 30 seconds.

Reduce the machine load. If the machine's final speed is then not reached, al- low the machine to cool down. 9 Service and maintenance Customer service and repair only through manufacturer or service workshops: Please find the nearest address at: www.festool.com/service Only use original Festool spare parts! Order No. at: www.festool.com/service To ensure constant air circulation, always keep the cooling air openings in the motor housing clean and free of any obstruction. In the event of a slowdown in performance or in- creased vibrations, blow and clean cooling air openings.

Keep the contacts on the machine, charger and battery pack clean. For service, maintenance, disposal and transport of the battery pack, note enclosed instructions of the battery pack! 10 Accessories Use only original Festool sanding pads.
