Bosch abrasive sheets: The uniform spacing
between grains minimizes filling or loading.
The high quality aluminum oxide sheet with
heavy backing cuts faster and lasts longer.
The following are recommended abrasive
sheets and applications:
Wood
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)
Paint/Enamels and
Primers and fillers
For removing paint.
For sanding primer.
For final sanding of
primers between
coats.
There are also different types of paper made
for wood, paint and other surfaces.
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.

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.
