5 Maintenance
5.1 General
During operation blast machines are exposed to wear. In order to ensure safe operation and high
efficiency the blast machines should be maintained according to the following check lists.
Prior to maintenance, make sure that the air valve of the compressor is closed and the whole
system is depressurized!
5.2 Daily check list
(1) Pot.
Open inspection door.
Check the gasket and the pop-up valve of the filling port by
hand for wear.
(2) Air, suction and blast hose.
Check the hoses for sharp bends, causing high loss of energy
and rapid wear.
No vehicles should pass over hoses!
Check the gaskets of the couplings.
(3) Nozzle.
Check the nozzle gasket and replace it at the first sign of wear.
Check the nozzle for wear and replace it if necessary.
(4) Remote control valves and
accessories.
Open the petcock of the remote control valve RMS-1500 and
check for water. If water is detected check the moisture
separator (see section 5.3).
Check the fittings of the remote control valves for tightness.
(5) Dust container.
Empty dust container.
5.3 Weekly check list
(1) Moisture separator.
Remove and check the filter element. If necessary clean the filter
and the sight glass with soap and warm water and dry it with
compressed air.
A dirty filter causes loss of pressure in the system!
(2) Air, suction and blast hoses.
Check all couplings and screws for wear or breakage and
replace them if necessary.
