1. Switch off the device at the mains switch.
2. Detach the cooling water hose from the cooling water supply intake.
Leave the hose on the cooling water outlet (OUT) attached securely
to the device.
3. Allow compressed air to flow through the cooling water hose towards
the device. Wait until all the water has flowed out of the device before
detaching the compressed air supply.
4. Loosen the counter nut on the water cooling intake (IN) of the device
by hand. Unscrew the counter nut from the nozzle.
If the nut is stiff, counter the hexagon bolt with pliers.
5. Detach the supply hose from the device.
6. Unscrew the dirt trap from the intake nozzle.
Use flat nose pliers to do this.
7. Clean the dirt trap and then screw back into the thread on the intake
nozzle.
8. Screw the hose back onto the intake nozzle with the counter nut.
9. Screw the counter nut hand-tight.
1. Switch off the device at the mains switch and prepare for the descaling
process accordingly.
Add descaler to the water cooling circuit via the intake using
a pump or funnel. The descaler flows back out through the
water cooling return hose and into a container with a suffi-
cient volume (approx. 15 liters).
LAUDA descaler is required for the descaling process (cat-
alog number LZB 126, 5 kg per pack). Read the safety
information and instructions on the packaging before using
the chemicals.
2. Detach the cooling water hose from the cooling water supply intake.
3. Detach the cooling water hose from the cooling water supply outlet.
4. Place the loose end of the return hose into the container.

funnel).
