In case of overload the LED glows red. In this case you have to remove
the load. For longer disregard of the red LED it follows a self-contained of
the machine. After discharge and reengagement one can drill again.
thermal: When continuous overload is applied (despite the electronic device)
a thermal protection will protect the motor. The machine disengages itself in
this case and can be put into operation after waiting for cooling down
(approx. 2 min.) The time needed to be able to restart the machine will be
vary dependent on overheating of the coil and the ambient temperature.
To speed up the cooling down of the machine let the machine after the
restart run 1-2 min. without load.
The stop of the machine caused by overload protection is no failure. After an adequate time it is
possible to restart working!
Water Supply
The DBM131 is designed for wet-and dry core drilling. The water supply has to stay on the spindle always.
Never drill without water supply due the spindle could be damaged. If there is water leakage between the
water supply ring and the gearbox housing you have to change the water supply respectively replace the
shaft seals by new and slight greasy shaft seals. These are available about dealers or manufacturer. The
water supply (black plastic ring) can only remove by pull down. The mounting of the water supply occurs to
push open till it snapped. Pay attention to the position of the dowel (for protection against twist)
Attention ! Do not damage the seal rings during the mounting.
The machine has an external water supply through the work spindle. With the help of the water tap you
can regulate the water quantity.
The water supply is equipped with a connector for Gardena-hose coupling.
Attention! Water pressure not higher than 3 bar.
In case of drilling “overhead” you have to exhaust the leak out water at the drill hole by suction
ring and wet-vacuum cleaner for reasons of safety at work and reliability.

device.

- Keep the electric tool clean
