Electrical connec-
tion and operation
The mains voltage must correspond
to the voltage on the rating plate!
To switch the tool on, push the safety sliding
switch (1.1) forwards. The tool is switched off by
gently press-ing the rear end of the switch.

Extension cord
If an extension cord is required, it must have suf-
fi cient cross-section to prevent an excessive drop
in voltage or overheating. An excessive drop in
voltage reduces the output and can lead to failure
of the motor. The table below shows you the cor-
rect cord diameter as a function of the cord length
for the RAS 115.04 E.

Use only U.L. and CSA listed extension cords.
Never use two extension cords together. Instead,
use one long one.
Note: The lower the AWG number, the stronger
the cord.
Electronic control
The tool has full-wave electronics with the
following features.
Do not use the rotary sander if the
electronic control is defective, since this can lead
to excessive speeds. A defect of this kind can be
recognized by the fact that the smooth run-up is
absent, the noise level under no-load conditions
is higher or the speed cannot be controlled.
Smooth start-up
The smooth start-up ensures jolt-free startup.
Speed adjustment
2.1
You can regulate the speed steplessly between
1500 and 4000 rpm using the adjusting wheel
(2.1). This lets you optimize the sanding speed to
suit the material (see "Working with the tool").
Constant speed
The pre-selected speed remains constant whether
the tool is in operation or in neutral position.
Temperature control
To prevent overheating, the safety electronics
switch the tool off when it reaches a critical motor
temperature. Let the tool cool down for approx.
3-5 minutes before using it again. The tool re-
quires less time to cool down if it is running, i.e.
in neutral position.
Tool settings
Always remove the power plug from
the socket before carrying out any work on the
power tool.
Extraction hood AH-RAS D 115
The extraction hood AH-RAS D 115 (3.1)
can be used in conjunction with the sanding
pads STF D 115.

a) Fitting
Before fi tting the extractor hood, ensure that the
clamping lever is in “released” position (3.4). Press
the extractor hood onto the clamping throat (3.2)
of the rotary sander and secure the hood by mov-
ing the clamping lever forward (3.3).
Do not work with the machine unless the extrac-
tor hood is clamped fi rmly and securely to the
clamping throat. If the clamping force is reduced
as the result of frequent use, the clamping lever
can be re-adjusted.
