Selecting Sanding/Grinding Sheets
GRINDING
The diamond paper accessory
allows for the Multi-Max™ to be
used for grinding away cement,
plaster or thin set. Preparing the surface for tile
replacement is a common application for this
accessory.
The diamond paper needs to be mounted to
the backing pad prior to use.
Select a low to high speed depending on the
material removal rate desired.
The carbide rasp accessory also
allows the Multi-Max™ to grind
away cement, thinset mortar,
plaster, and also wood. This accessory is
commonly used to prepare for tile replacement
or rasping wood to smooth a surface or
remove material.
The speed should be set at high speed for
aggressive material removal or at low speed
for a more detailed removal of material.
Do not apply excessive pressure on the tool-let
it do the work.
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.
Grind 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
premature wear on the diamond paper sheet.

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.
Select low to medium speed.
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, make sure
that the screw head does not make contact
with surface during the scraping process (a 30
- 45 degree pitch is recommend). 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 oscillating tool in
this manner will prolong switch and motor life,
and greatly increase the quality of your work.
Move the oscillating tool in long steady strokes
parallel to the grain using some lateral motion
to overlap the strokes by as much as 75%.
DO NOT apply excessive pressure - let the
tool do the work. Excessive pressure will result
in poor handling, vibration, and unwanted
sanding marks.
