specified safety rules.
Inspection after screw connections
Screws - nuts - fittings and bolts on the machine should be re-tensioned after two hours of operation.

The ejector spout's swivel is exposed to both cold and heavy wear - therefore use cold-resistant
grease that can handle up to -40 degrees. Points 4 and 5.
Wear steel and skid pads are exposed to heavy wear - check and carry out the replacement or
reversal of wear steel before damage occurs to the hull itself and mounting brackets.
Replacement of feeder blade – replacing the feeder blade, the opposite blade must be replaced
also at the same time to stop vibrations.

cleaning.

machine in acid-free oil.
