Extension cord
If an extension cord is required, it must
have suffi 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 correct cord
diameter as a function of the cord length for
the RO 150 FEQ.
Use only U.L. and CSA listed extension cords.
Never use two extension cords together. In-
stead, use one long one.
Note: The lower the AWG number, the stron-
ger the cord.
Electronic control
ELECTRONIC
The tool has full-wave electronics with
the following features:
Smooth start-up
The smooth start-up ensures jolt-free start-
up.
Speed adjustment
You can regulate the speed steplessly between
3300 and 6800 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.
