The grout blades can handle both sanded and
unsanded grout. If you notice the blade
clogging during the grout removal process,
you can use a brass brush to clean the grit,
thus exposing the grit again.
The grout blade geometry is designed so that
the blade can remove all grout up to the
surface of a wall or corner. This can be
accomplished by ensuring that the
segmented portion of the blade is facing the
wall or corner.
SCRAPING
Scrapers are suitable for removing old coats
of varnish or adhesives, removing bonded
carpeting, e.g. on stairs/steps and other
small/medium size surfaces.
Rigid scrapers are for large area
removal, and harder materials
such as vinyl flooring, carpeting
and tile adhesives. When
removing strong, tacky adhesives, grease the
scraper blade surface with (petroleum jelly
or silicone grease) to reduce gumming up.
The carpet/vinyl flooring removes easier if it
is scored prior to removal so the scraper
blade can move underneath the flooring
material.
Flexible scrapers are used for
hard to reach areas and softer
material such as caulk.
Mount the scraper blade with the logo side
facing up. With the flexible scraper, use a 30
- 45 degree pitch for best performance. This
can be accomplished by making sure that the
tool is at an angle to the blade. You should
be able to see the blade flex during the
scraping process.
If you are removing caulk from a delicate
surface such as a bath tub or tile back splash,
we recommend taping or protecting the
surface that the blade will rest on. Use
rubbing alcohol to clean the surface after the
caulk and/or adhesive is removed.
Turn the tool on and place desired accessory
on the area where material is to be removed.
Begin with light pressure. The oscillating
motion of accessory only occurs when
pressure is applied to the material to be
removed.
Excessive pressure can gouge or damage the
background surfaces (e.g,. wood, plaster).
SANDING
Sanding accessories are suitable
for dry sanding of wood, metal,
surfaces, corners and edges and
hard to reach areas.
Work with the complete surface of the
sanding pad, not only with the tip.
Corners may be finished using the tip or edge
of the selected accessory, which should
occasionally be rotated during use to
distribute the wear on the accessory and
backing pad surface.
Sand with a continuous motion and light
pressure. DO NOT apply excessive pressure -
let the tool do the work. Excessive pressure
will result in poor handling, vibration, and
unwanted sanding marks and premature wear
on the sanding sheet.
Always be certain that smaller workpieces are
securely fastened to a bench or other
support. Larger panels may be held in place
by hand on a bench or sawhorses.
Open-coat aluminum oxide sanding sheets
are recommended for most wood or metal
sanding applications, as this synthetic
material cuts quickly and wears well. Some
applications, such as metal finishing or
cleaning, require special abrasive pads which
are available from your dealer. For best
results, use Dremel sanding accessories
which are of superior quality and are carefully
selected to produce professional quality
results with your oscillating tool.
The following suggestions may be used as a
general guide for abrasive selection, but the
best results will be obtained by sanding a test
sample of the workpiece first.
Grit Application
Coarse For rough wood or metal
sanding, and rust or old
finish removal.
Medium For general wood or metal
sanding
Fine For final finishing of wood,
metal, plaster and other
surfaces.
With the workpiece firmly secured, turn tool
on as described above. Contact the work
with the tool after the tool has reached its full
speed, and remove it from the work before
switching the tool off. Operating your
