Sanding Tips
SELECTING THE SANDING BELT
It is very important that you select the proper
belt for each particular application. To do this
you should understand the method of marking
or coding on the back of most belts. “CLOSED
COAT” means the surface is densely covered
with as much grit as the adhesive will hold.
“OPEN COAT” means the grit has been
applied evenly, but openly to the surface. An
“open coat” will not clog or fill as readily as
“closed coat”. In general, aluminum oxide
abrasive belts are best for woodworking
because they are tougher and last longer.
Sanding belts should be stored in a cool, dry
place. Do not store near heat or near a window
where the sun can reach them.
TECHNIQUE
Grasp the handles firmly. Start the sander with
the belt off the work (NOTE: never start or stop
-8-
TRACKING ADJUSTMENT
Turn sander upside down and plug it into the
power source. Hold the sander firmly with one
hand, engage trigger switch to turn the tool
“ON”, and note the tracking of the sanding
belt. If the belt runs outward (towards the
open side of the sander) turn tracking
adjustment knob counter-clockwise. If the belt
runs inward, turn the knob clockwise. Adjust
the belt in this manner until the edge of the belt
runs flush with the outer edge of both pulleys
and covers the platen protector. Your sander is
now ready for use. In some cases, the belt will
require a slight readjustment after it is applied
to the work surface, so note the tracking
carefully during the first minutes of operation
and readjust as required.
ADJUSTABLE TOP HANDLE
The top handle provided should always be
used to guide and balance the tool. Grip the
tool by the multi-position top handle, and the
rear handle, for safe control and ease of
operation. To adjust the top handle, loosen
wing knob at least two full turns, position
handle and retighten knob firmly.
DUST EXTRACTION
Proper dust removal will extend abrasive life
and produce more consistent results. The
integral dust extraction system collects
sanding dust in the dust bag assembly. Bag
should be emptied when it is no more than half
full, and should be replaced when the surface
becomes clogged with dust or efficiency will
be reduced. To empty or replace bag, pull the
bag free of dust port. Open the zipper on the
rear of the bag, and empty contents into
suitable receptacle.
To install bag, firmly push the bag into place
on the dust port so that it covers the "O" ring
to create a seal and the metal flange on dust
bag makes contact with the static clip as
shown. The static clip is provided to dissipate
static electricity that accumulates in the bag
and can cause annoying shock to the user.
For added efficiency, a vacuum hose and
adaptor (optional accessories) are also
available which will allow your sander to be
connected to a shop vacuum system. See
your Bosch catalog for optional Bosch
Airsweep accessories.
