Extension cord
If an extension cord is required, it must have
sufficient 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 correct cord diameter as a function of
the cord length for the RO 125 FEQ.
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:
ELECTRONIC
Smooth start-up
The smooth start-up ensures jolt-free startup.
Speed adjustment
You can regulate the speed steplessly between
3000 and 6000 rpm using the adjusting wheel
(3.1). This lets you optimize the sanding speed
to suit the material.
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 requires less time to cool down if it is
running, i.e. in neutral position.
Dust extraction
Always connect the tool to a dust
extractor.
You can connect a Festool extractor with an
extractor hose diameter of 27 mm to the dust
extraction port (4.1).
Tool settings
Always remove the power plug
from the socket before carrying out any work
on the power tool.
Sanding motion
You can use the switch (5.1) to set two diffe-
rent sanding motions.
The change can only be made
when the sanding pad is stationary, as the
switch is locked in place during operation for
safety reasons.
Rotex rotary motion (coarse sanding,
polishing)
The Rotex rotary motion is a combination
of rotary and eccentric motions. This
motion is recommended for sanding with
aggressive material removal (coarse
sanding) and polishing.
Slide the switch (5.1) into the right position.
Eccentric motion (fine sanding)
This motion is recommended for sanding
with low material removal for a scratch-
free finish (fine sanding).
Press the switch (5.1) down and push it into
the left-hand position.
