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
• Always latch the rear clamp lever when the
tool is not in use.
• 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. (See REMOVING PSA
ABRASIVE SHEETS on page 8.)
