Decreasing the oscillating frequency:
Turn thumbwheel (3) in clockwise
direction.
The oscillating frequency depends on the appli-
cation and the application tool. Example:
– High oscillating frequency:
Sanding, sawing, using as a rasp, polishing
stone and metal.
– Low oscillating frequency:
Polishing of varnish and veneers.
Working instructions.
Sanding
Typical application: Dry sanding of wood and
metal, especially of smaller surfaces, corners and
edges, as well as hard to reach locations.
Work with the complete surface of the sanding
plate, not only with the tip. Select a high oscillat-
ing frequency. Sand with continuous motion and
light pressure. Applying excessive pressure does
not increase material removal; only the sanding
sheet wears more quickly.
Sawing
Typical application: Sawing of thin steel sheet,
wood and plastic components.
Select a high oscillating frequency. Round saw
blades can be loosened and attached offset, in
order to provide for uniform wear.
Scraping
Typical application: Scraping off old coats of var-
nish or adhesives, removing bonded carpeting,
e. g., on stairs/steps or other small/medium-
sized surfaces.
Select a medium to high oscillating frequency.
Storage
Fully insert the fastening element (6a)
into the tool holder in order to protect it
against damage and contamination.
Engage the quick-clamping lever.
Repair and customer service.
When working metal under extreme
operating conditions, it is possible for
conductive dust to settle in the interior of the
power tool. The total insulation of the power
tool can be impaired. Blow out the interior of
the power tool via the ventilation slots fre-
quently with dry and oil-free compressed air,
and connect a residual current device (RCD) on
the line side.
If the supply cord of this power tool is damaged it
must be replaced by a specially prepared cord avail-
able through the BTI customer service centre.
If required, you can change the following parts
yourself:
– Application tools
– Fastening element (6a)
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an after-sales service
centre for BTI power tools.
In all correspondence and spare parts orders,
please always include the 6-digit order number
given on the nameplate of the machine.

Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
