You can use the BOSCH Random Orbit Sander to work on wood, wooden materials or painted surfaces to optimum effect. In addition to the oscillating motion, the sanding plate on the BOSCH Random Orbit Sander rotates. The random orbit motion created as a result of this is where the sander gets its name from. This ensures that the sanding grit moves very fast on the work piece surface and can therefore remove a large amount of material. Only when sanding metal or stone does the random orbit sander run somewhat slower too. It is suitable for even work pieces and for work pieces with inward or outward curves. The round sanding plate is supported slightly elastically and adapts ideally to the surface.

Bosch Random Orbit Sanders are ergonomically shaped and therefore easy to guide precisely. The best thing to do is to use the auxiliary handle on the front of the tool and guide it with both hands. In this way, you can work safely for long periods of time without getting tired. First of all however, you have to select the appropriate coated abrasive. Depending on the surface and material, there are different sanding sheets. Use polishing fleeces for the finishing touch.

As a rule, you should begin sanding using a coarse grit and then select a finer grit for each sanding run. The following applies as a rule of thumb: you should select a grit that is twice as fine for every subsequent work step. Example grit sequence: 40  80  180  360  600  1200.

Before you start sanding, you can preselect the orbital stroke rate using the BOSCH Electronic. To do this, set the appropriate orbital stroke rate at the setting wheel on the top or the front of the auxiliary handle. You can even change the orbital stroke rate during operation. Select a low orbital stroke rate if you want to remove paint, for example. If the sanding plate moves too fast, the friction is very high, the paint gets hot, melts and gets stuck in the sanding sheet. The same applies for soft materials. When you set a high orbital stroke rate, you can remove material faster. In general, setting the orbital stroke rate is a matter of feeling: If the tools removes material too fast, feel free to switch down one or two steps. Guide the random orbit sander in slow, constant circular motions over the surface. You will notice how easy it is.

To ensure that you sand down smoothly and without grooves, BOSCH Random Orbit Sanders have either BOSCH Powermatic (PEX 420) or a sanding plate brake. BOSCH Powermatic allows you to start the sanding tool at a low orbital stroke rate. Only when you press the tool onto the material does the orbital stroke rate smoothly increase automatically until it reaches full power. The sanding plate brake also brakes the sanding plate so that it does not move at full speed from the start, rather it sands down the work piece surface smoothly at first.

Random Orbit Sanders from BOSCH are all equipped with the BOSCH Micro-Filter System . This ensures that dust that you would otherwise breathe in or would otherwise fly into your eyes lands in the filter box. You can then very conveniently remove and empty the box. If you remove a large amount of material on large surfaces, you can also connect your random orbit sander to a BOSCH All-Purpose Vacuum or a household vacuum cleaner.
