INSPECTION AND MAINTENANCE
To ensure full availability of the washer and to extend its lifetime, it is necessary to perform maintenance operations in
regular intervals and immediately report and repair all malfunctions, defects and damages.
During replacement of water, washing and cleaning of washer, i.e. during the so-called maintenance shutdown, remove
side cover of control chamber and check if all cable connections of electrical components are properly tightened. As the
continuous vibrations occur during machine operation, the cable connections may get loose and contribute to improper
functioning of the washer. If any loose terminals are found, tighten them by using appropriate tools. It is also necessary
to check the condition of connections between the hoses connecting the pump with supply lines and delivering the
washing medium from pump to sprinkling nozzles.
The main “SG” switch completely disconnects the machine and plays the role of an emergency switch. If necessary, this
switch can be blocked by locking with a padlock for the time of maintenance and repair shutdown. If any warning or
protecting device activates, the machine operation is automatically interrupted. The machine can be restarted only upon
repairing the cause of malfunction and elapsing the approx. 5 seconds required for resetting the controller after failure.
The water level in the washer should be checked on a regular basis, since the amount of water inside the machine
decreases during machine operation as a result of vaporising, particularly of warm water. It is also necessary to check
the washer for foaming, which in most cases is caused by excessive amount of dirt and/or washing fluid. Foam must be
removed immediately. If water level is too low and foam is present, the washer may function improperly, the washing
may be ineffective and the risk of clogging the nozzles may occur.
Please remember that granulate should not be present in the sedimentation tank that is separated from washing
chamber by the barrier. Otherwise, the granulate present in the tank will not be transported to the pump and the result of
wheel washing will be worse. If any granulate is found in the tank, it should be removed and poured into washing
chamber.
