v. Hold the machine correctly. Prepare to counteract normal or sudden movements - hold the machine with both hands.

2.2 Machine-related safety instructions

• The manufacturer's handling and processing instructions must be observed without fail if explosive or self-igniting dusts are likely to occur during sanding.
• If dust dangerous to health is produced during sanding, the machine should be connected to an appropriate extraction device and the safety regulations that apply to the working material should be observed.
• The operating pressure should not exceed 6.5 bar.
• The machine should only be operated with sandpaper. Grinding wheels and parting grinder discs are not permitted.
• Only work with correctly processed compressed air. Using the Festool service unit VE guarantees this.
• Only use original Festool accessories.
• Wear suitable protection such as ear protection, safety goggles, a dust mask for work which generates dust, and protective gloves when working with raw materials and when changing tools.
• The permissible rotational speed of the accessory must be at least as high as the maximum speed specified on the machine. Accessories that rotate faster than the permissible level can rupture.
• Proceed with caution in unfamiliar surroundings that may contain electricity or other supply cables that harbour hidden dangers. Make sure that there are no electrical cables, gas pipelines or similar that, if damaged, could pose a hazard when the machine is used.

2.3 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.

3 Noise and vibration information

The typical values determined in accordance with EN ISO 15744are:

Sound pressure level 80 dB(A)

Noise level 91 dB(A)

Measuring uncertainty allowance K = 3 ~dB

The noise level can exceed 85 dB(A) during operation. Wear ear protection!

Vibration emission level a_h an uncertainty K measured in accordance with EN ISO 8662:

Handle a_b = 4,5m / s^2

$$ \dot {K} = 2, 0 \mathrm {m} / \mathrm {s} ^ {2} $$

Auxiliary handle a_b = 4,0 ~m / s^2

$$ \dot {K} = 2, 0 \mathrm {m} / \mathrm {s} ^ {2} $$

The emission values specified (vibration, noise) were measured in accordance with the test conditions stipulated in EN ISO 15 744/EN ISO 8662 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 air tool is used. If the air 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.

4 Compressed-air supply and commissioning

Make sure that the pneumatic tool is switched off when you connect the compressed-air supply.

4.1 Compressed-air processing

The Festool service unit VE should always be used to ensure that Festool pneumatic tools function correctly. Consisting of a filter, control unit, condensation drain and lubricator, the service unit cleans and lubricates the compressed air and keeps it free of condensation. Here, the lubricator should be set so that a drop is applied to the compressed air approx. every 7-10 minutes.

Damage that occurs as a result of incorrect compressed-air processing is excluded from warranty claims.

We recommend a service unit with a 3 / 8" connector, when up to two Festool pneumatic tools are used. A compressor that supplies at 500 l/min and at an operating pressure of 6 bar should be used to supply compressed- air. The diameter of the piping system must be sufficiently large (at least 9 mm).

4.2 IAS 2 hose connector

The sander is a pneumatic tool for connection to the Festool IAS 2 system. This hose system combines three functions in one hose:

• Compressed air supply [3-1]
• Exhaust air extraction [3-2]
• Dust extraction [3-3]

Connection and disconnection - see Fig. 2.

4.3 Commissioning

Switch [1-1] serves as an On/Off switch (I = On / 0 = Off).

5 Machine settings

The machine should always be disconnected from the compressed air supply before any work is carried out on the machine.

5.1 Speed adjustment

You can regulate the speed steplessly between 5,500 and 7,000 min-1 using the adjusting wheel [1-2]. This enables you to optimise the cutting speed to suit the material.

5.2 Dust extraction

The sanding dust is extracted directly through the extraction channels in the sanding shoe directly at the point of sand-ing.

To guarantee optimized dust extraction, we recommend using Festool extractors with automatic switch-on/switch-off device for compressed-air machines.

5.3 Attaching sanding material

Self-adhesive abrasives such as Stickfix sandpaper and sanding fleeces can be attached to Stickfix sanding shoes.

The abrasives are simply pressed onto the sanding shoe [1-3] and pulled off after use.

Always use original Festool sanding materials!

Use only sanding shoes with undamaged Velcro coatings.

6 Maintenance and care

The machine should always be disconnected from the compressed air supply before any work is carried out on the machine.

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

6.1 Vanes

We recommend that the vanes on the motor be replaced after approx. 500 operating hours.

6.2 Lubrication

If the machine is not used for longer periods, e.g. for a weekend, introduce 1 or 2 drops of lubricating oil into the compressed-air supply [2-1] on the machine prior to use.

6.3 Replacing the silencer

The silencer on the IAS 2 connecting piece must be replaced at regular intervals to maintain the power of the pneumatic tool.

7 Accessories, tools

Use only original Festool accessories and Festool consumable material intended for this machine because these components are designed specifically for the machine. Using accessories and consumable material from other suppliers will most likely affect the quality of your working results and limit any warranty claims. Machine wear or your own personal workload may increase depending on the application. Protect yourself and your machine, and preserve your warranty claims by always using original Festool accessories and Festool consumable material!

The order numbers of the accessories and tools can be found in the Festool catalogue or on the Internet under "www.festool.com".

8 Disposal

Do not throw the tool in your household waste! Dispose of machines, accessories and packaging at an environmentally responsible recycling centre. Observe the valid national regulations.

9 Warranty

For our tools, we give warranty for material and production defects in accordance with the locally applicable legal provisions, but in any case for at least 12 months. Within the EU member states, the warranty period is 24 months (verification through invoice or delivery note). Damage caused by, in particular, natural wear, overloading, incorrect handling, or damage caused by the operator, or damage caused through use of the equipment contrary that specified in the operating manual, or damage which was known at the time of purchase, is not covered by the warranty. Furthermore, damage caused by the use of non-original accessories and consumable materials (e.g. sanding pads) is also excluded. Complaints can only be recognised if the tool is returned while still assembled to the supplier or an authorised Festool Customer Service workshop. Keep the operating manual, safety instructions, spare parts list and purchase receipt in a safe place. Otherwise the respective, current warranty conditions of the manufacturer shall apply.
