SANDING TIPS

Bosch orbital sanders are designed to produce exceptional finishes on wood surfaces, speed stock removal, or to remove lacquer, varnish, and other coated finishes.

Orbital sanding provides fast, smooth final finishes. And this model can sand flush on all three sides of the tool to get in tight places typical of cabinets, desks and shelving.

Starting and stopping of sanding - Contact the work with the tool after sander has reached its full speed and remove it from the work before turning the switch “OFF”. Operating in this manner will prolong switch and motor life and will greatly increase the quality of your work.

This sander’s even weight distribution and the prevention of paper slippage by the

SheetLoc system virtually eliminate any benefit from pressing on the sander. 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, as well as premature wear out of the pad.

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, then medium, and then finish with a fine or extra-fine grit. 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 grit 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.

STORING THE SANDER

Do not store tool with PSA sheets on pad, as sanding creates heat, which will cause an adhesive bond between the paper and the pad to harden when paper and pad cool down.
