Safety Warnings for Sander

• Use the machine only for dry sanding. Penetration of water into the machine increases the risk of an electric shock.
• Pay attention that no persons are put at risk through sparking. Remove any combustible materials in the vicinity. Sparking occurs when sanding metal materials.
• Caution, fire hazard! Avoid overheating the object being sanded as well as the sander. Always empty the dust collector before taking breaks. In unfavorable conditions, e.g., when sparks emit from sanding metals, sanding debris in the dust bag, micro filter or pa- per sack (or in the filter sack or filter of the vacuum cleaner) can self-ignite. Particularly when mixed with remainders of varnish, poly- urethane or other chemical materials and when the sanding debris is hot after long periods of working.
• Secure the A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
• Products sold in GB only: Your product is fit- ted with an BS 1363/A approved electric plug with internal fuse (ASTA approved to BS 1362).

If the plug is not suitable for your socket out- lets, it should be cut off and an appropriate plug fitted in its place by an authorised customer service agent. The replacement plug should have the same fuse rating as the original plug. The severed plug must be disposed of to avoid a possible shock hazard and should never be inserted into a mains socket else- where.

• Products sold in AUS and NZ only: Use a residual current device (RCD) with a rated residual current of 30 mA or less.

Dust/Chip Extraction

• Dusts from materials such as lead-containing coatings, some wood types, minerals and metal can be harmful to one’s Touching or breathing-in the dusts can cause allergic reactions and/or lead to respiratory infections of the user or bystanders.
• Certain dusts, such as oak or beech dust, are considered as carcinogenic, especially in connection with wood-treatment additives (chromate, wood preservative). Materials containing asbestos may only be worked by specialists.
  • As far as possible, use a dust extraction system suitable for the material.
  • Provide for good ventilation of the working place.
  • It is recommended to wear a P2 filter- class respirator.
  • Observe the relevant regulations in your country for the materials to be worked.
• Prevent dust accumulation at the work- place. Dusts can easily ignite.

Integrated Dust Extraction with Dust Box (see figures E–H)

• Attach the dust box 3 onto the extraction outlet 10 until it latches.
• The filling level of the dust box 3 can easily be checked through the transparent container.
• To empty the dust box 3, pull it off toward the bottom with a twisting motion.
• Before opening the dust box 3, it is recommended to loosen the dust from the filter element by gently striking it against a firm support (as shown in the figure).
• Hold the dust box 3 firmly, fold the filter element 11 upward and empty the dust box. Clean the thin plates of the filter element 11 with a soft brush.
• Note: To ensure optimum dust extraction, emp- ty the dust box 3 in good time and clean the fil- ter element 11 at regular intervals.
• When working vertical surfaces, hold the power tool in such a manner that the dust box 3 faces downward.

External Dust Extraction (see figure I)

• Mount a vacuum hose 12 onto the extraction outlet 10. Connect the vacuum hose 12 with a vacuum cleaner. An overview for the connection of various vacuum cleaners can be found at the end of these instructions.
• The vacuum cleaner must be suitable for the material being worked.
• When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a special vacuum cleaner.
• When working vertical surfaces, hold the power tool in such a manner that the vacuum hose faces downward.

Operation

Starting Operation
Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230 V can also be operated with 220 V.

Switching On and Off

• To start the machine, push the On/Off switch 2 forward so that the “1” is indicated on the switch.
• To switch off the machine, push the On/Off switch 2 toward the rear so that the “0” is indicated on the switch.

Preselecting the Orbital Stroke Rate

• With the thumbwheel for preselection of the orbital stroke rate 1, you can preselect the required orbital stroke rate, even during operation.
  • 1–2       Low stroke rate
  • 3–4        Medium stroke rate
  • 5–6       High stroke rate
• The required stroke rate depends on the material and the working conditions and can be deter- mined through practical testing.
• After longer periods of working at low stroke rate, allow the machine to cool down by running it for approx. 3 minutes at maximum stroke rate with no load.

Working Advice

• Before any work on the machine itself, pull the mains plug.
• Wait until the machine has come to a stand- still before placing it down.

Sanding Surfaces

• Switch the machine on, place it with the complete sanding surface on the surface to be worked and move the machine with moderate pressure over the workpiece.
• The removal capacity and the sanding pattern are mainly determined by the selection of the sanding sheet, the preselected orbital stroke rate and the applied pressure.
• Only flawless sanding sheets achieve good sanding capacity and extend the service life of the machine.
• Pay attention to apply uniform sanding pressure; this increases the working life of the sanding sheets.
• Intensifying the sanding pressure does not lead to an increase of the sanding capacity, but to increased wear of the machine and the sanding sheet.
• A sanding sheet that has been used for metal should not be used for other materials.
• Use only original Bosch sanding accessories.

Rough Sanding
Attach a sanding sheet with coarse grain. Apply only light pressure to the machine so that it runs at a higher stroke rate and high material removal is achieved.

Fine Sanding

• Attach a sanding sheet with fine grain.
• By lightly varying the application pressure or changing the orbital stroke rate, the sanding plate stroke rate can be reduced whereby the orbital action is maintained.
• With moderate pressure, move the machine in a circular pattern or alternately in lengthwise and crosswise directions over the workpiece. Do not tilt the machine to avoid sanding through the workpiece (e.g. when sanding veneer).
• After finishing the working procedure, switch the power tool off.

Polishing

• For the polishing of weathered paint or buffing out scratches (e.g., acrylic glass), the machine can be equipped with appropriate polishing accessories such as lamb’s wool bonnet, polishing felt or sponge (accessories).
• Select a low stroke rate (setting 1–2) for polishing in order to avoid excessive heating of the surface.
• Apply the polish onto a somewhat smaller sur- face than you intend to polish. Work the polishing agent in with a suitable polishing tool applying it crosswise or with circular motion and moderate pressure.
• Do not allow the polishing agent to dry out on the surface, otherwise the surface can become damaged. Do not subject the surface to be polished to direct sunlight.
• Clean the polishing accessories regularly to ensure good polishing results. Wash out polishing accessories with a mild detergent and warm water; do not use paint thinner.
