DUST EXTRACTION
The integral dust extraction system collects sanding dust in the dust bag. For maximum efficiency, cloth bags should be emptied when they are no more than half full, and should be replaced when the surface becomes clogged with dust or efficiency will be reduced. To replace bag, slide connector in direction of arrow A until it stops. Insert bag support into the pocket provide on bag.
Then slide bag and support in direction of arrow B onto connector and dust port (Fig. 4).
A vacuum hose and adaptor (optional accessories) are also available which will allow your random orbit sander to be connected to a shop vacuum system (Fig. 5). See your Bosch catalog for these optional Bosch Airsweep accessories.
FRONT HANDLE
Your sander is equipped with a removable front handle when sanding in tight quarters. To remove handle, remove screw with allen wrench provided. Always reinstall handle for normal operation. Depending on the task, you may grip the rear handle alone, the rear handle and the front handle, or the rear handle and the top of the ergonomically contoured soft grip motor housing, which is designed for that purpose (Fig. 1).
SANDING TIPS
This sander has been designed for even weight distribution which virtually eliminates the use of pressure. Excessive pressure to the sander may result in an uneven sanding job and premature grit wear. Constant and excessive pressure can cause overheating and possible damage to the motor.
It's usually best to work in strokes that parallel the grain, using some lateral motion so the main strokes are overlapped as much as 75%.
If the surface is rough, start sanding with a coarse grit sheet, then medium and then finish with a fine or extra fine abrasive. This procedure will vary with different types of materials and work. Continue to sand with each grit until the surface looks uniform. When going from one grit size to a finer size, do not skip more than two sizes.
To remove the greatest amount of stock, use a coarse grit and move the sander steadily over the entire surface against the grain as well as with the grain. DO NOT REMAIN IN ONE SPOT TOO LONG. It may remove too much material and uneven sanding will result. Sanding with the grain of the wood gives the smoothest final finish.
