Save all warnings and instructions for future reference.

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

2.2 Machine-related safety instructions

- Dust that is harmful to your health may be produced as you work (e.g. paint products containing 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 example 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 extractor may self-ignite in unfavourable conditions 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. Remove the sanding pad for closer inspection. Have the damaged parts repaired before use. Broken sanding pads and damaged machines can cause injuries and machine instability.
• Always use original Festool sanding pads.
• While using the long-life dust bag be aware of electric charge. Always when possible use an antistatic suction hose with the power tool. A 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 supplied via residual current device with a rated residual current of 30 mA or less.

Recommendation: Charge battery pack before further use.

6.3 Mains adapter

WARNING

Unauthorised voltage or frequency!

Risk of accident

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 the voltage specifications 120 V/60 Hz may be used.

The mains adapter (available as an accessory depending on the model) facilitates use of the cordless sanding technology with mains power, enabling you to switch between power supply sources. The mains adapter enables the mobile dust extractor's automatic electronic switch-on/shut-off function.

▶ Insert the mains adapter [3a]
▶ 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

WARNING

Risk of injury

▶ When working on power tools, always remove the batteries or disconnect the mains adapter first.

7.1 Electronics

Smooth start-up

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

Temperature cut-out

To avoid the motor overheating, the power consumption is limited at an excessive motor temperature. If the temperature continues to rise, the power 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 10000min^-1 using the adjusting wheel.

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

Sanding work Adjusting
wheel setting

- Sanding with max. abrasion	5 - 6
- Sanding off old paint
- Sanding of wood and veneered surface prior to paintwork
- Intermediate sanding of paintwork on surfaces
- Sanding thinly applied undercoat	4 - 5
- Sanding wood with sanding cloth
- Edge breaking on wooden parts
- Smoothing primed wooden surfaces
- Sanding solid wood and veneered edges	3 - 4
- Sanding rebate of windows and doors
- Intermediate sanding of paintwork at edges
- Light sanding of natural wood windows using sanding cloth
- Smoothing wooden surfaces using sanding cloth before staining
- Rubbing or removing excess limestone residue using sanding cloth
- Intermediate sanding of paintwork on stained surfaces	2 - 3
- Cleaning natural wood window rebate using sanding cloth
- Sanding stained edges	1 - 2
- Sanding of thermoplastics

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 consumables invalidates the right to claim under warranty.

If the StickFix coating on the sanding pad has worn out, the entire sanding pad can be replaced:

① Undo the four screws.
② Remove the sanding pad by pulling it downwards.
③ Attach the new sanding pad.
④ 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 sanding cloth can be attached quickly and simply to the StickFix sanding pad.

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

7.4 Dust extraction

WARNING

Dust hazard

▶ Dust can be hazardous to health. Always work with a dust extractor.
▶ Always read applicable national regulations before extracting hazardous dust.

Integral dust extractor with long-life dust bag

As standard, the sanders are equipped with an integral 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]

① Slide the dust bag onto the machine until it clicks into place.
If the suction power is decreasing, empty the dust bag.
1 Press the dust bag onto the actuating elements.
② Remove the dust bag by moving it towards the rear.
③ Open the flap on the dust bag.
④ Empty the dust bag and dispose of the waste.

Dust extraction with Festool's mobile dust extractor

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 extractor (with an extraction hose diameter of 27 mm) to the extractor connection piece [1-4].

① The start-up mode switches the mobile dust extractor 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.

The edge protector [1-7] prevents the sanding pad circumference from coming into contact with a surface (e.g. when sanding along a wall or a window), thus preventing back-kick of the machine, or machine damage.

① Push the edge protector into the groove on the machine.
② Slot the two ends of the edge protector into place until they click.

③ Loosen both ends of the edge protector.

④ Remove the edge protector by pulling it forwards.

8 Working with the machine

WARNING

Risk of injury

▶ Always secure the workpiece in such a manner that it cannot move while being machined.

Observe the following instructions:

• Do not overload the machine by pressing with excessive force! The best sanding results are achieved with moderate application pressure. The sanding capacity and quality are mainly dependent on the selection of the correct abrasive.
• Work in corners and on edges tends to subject the tip to increased stress and results in increased heat development. In such cases, work with reduced contact pressure.
• Hold the machine with one hand on the handle [1-8].

8.1 Warning signal

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, allow the machine to cool down.

9 Service and maintenance

WARNING

Risk of injury, electric shock

▶ When carrying out servicing and maintenance work, always remove the batteries or the mains adapter from the power tool first.
▶ All maintenance and repair work which requires the motor housing to be opened should always be carried out by an authorised service workshop.

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.
