If the nut is stiff, counter the hexagon bolt with pliers.
Use flat nose pliers to do this.
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.
