Operation
Water spray system (option)
Operating mode II ON
To activate the water spray system, set four ball valves to the position of operating
mode II.
Operating mode III Draining water and emptying the tank
If there is a possibility of freezing or before extended downtime we recommend drain-
ing the water from the system completely to prevent damage to the water spray sys-
tem. The diesel engine of the machine should be running to drain the tank faster (for
compressed air supply).
Operating mode IV Blowing out spray nozzles and pressure lines
Pressure lines and spray nozzles must be blown out if there is danger of freez-
ing. Set four ball valves to the position of operating mode IV and switch on the
water spray system using the screen button (24) (See Page 291). Leave the sys-
tem switched on until only air without water vapour comes out of all spray nozzles.
Finally, open the water filter (6) and drain the filter holder. Screw the filter holder with
the filter screen back onto the filter head.
ADVICE
If the water spray system function is not required, set the ball valve (1) to the posi-
tion of operating mode I. Thus, you disconnect the water tank from the compressed
air reservoir. This allows you to achieve the necessary reservoir pressure of the pneu-
matic system in the shortest possible time after the diesel engine has been started.
