heavy backing cuts faster and lasts longer.
The following are recommended abrasive
sheets and applications:
Applications
For preliminary sanding of
rough wood, unplaned
boards.
For mid-stage sanding and
smoothing of small
irregularities.
For finish and fine sanding
speed and sanding sheet
(sandpaper)
For removing paint.
For sanding primer.
For final sanding of
primers between coats.
Additional abrasive sheets can be conveniently
cut from large-size commercially available
sheets (standard size 9" x 11" (228 x 280mm).
Cut into two pieces of equal size. Choose the
proper grit for the job.
START OF SANDING
With the workpiece firmly secured, first place
the sander's pad on the work surface, then
switch the tool on.
DO NOT start the tool and bring it up to speed
before applying to the work

DO NOT apply excessive pressure when
switch the tool on (or at any other time)
Either method will likely create swirl marks.
Applying excessive pressure upon start-up will
also shorten the life of the switch
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.
• 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.
REMOVING THE SANDER
Remove the sander 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.
STORING THE SANDER
• Do not store tool with PSA sheets on pad,
as sanding creates heat, which will cause an
