MAINTENANCE
Inspections to be carried out every week: Hydraulic station:
Inspect for oil leakages, Check hoses, fittings, valves, and connections for leakages. Reseal if necessary. Check the oil
level, in the sight glass on the hydraulic tank side. Refill if necessary.
Degassing system
Check the degassing system. Check the degassing for snow particles at the CO2 outlet (can only be done when dry ice is
being produced)
Snow particles at the CO2 outlet indicate that the degassing filter is damaged. Replace the filter and gasket as described
under in this manual.
Inspections to be carried out every 400 hours / 3 months: Liquid CO2 filter:
Hydraulic station
Check the oil. Drain a small quantity of oil – 1 dl – from the hydraulic tank. Inspect the oil visually. If the oil is not clear,
bright, and light yellow it must be changed. Get a particle analysis of the oil if in doubt about the contamination degree.
Cold Jet recommends that the owner has a spare parts package in stock, so repairs can be made quickly and with little
loss of production time.
