7.3 ROUTINE MAINTENANCE
7.3.1 Daily checks
General cleaning: Blow-clean all the machine external parts with compressed air.
Gun cleaning: Blow-clean the trigger section of the gun with compressed air to eliminate any
residual grain that could block the mechanism.
Nozzle cleaning: to clean the nozzle, screw out the locking nut (1) at the extremity of the gun or of
the lance, extract the nozzle (2), clean it and replace it by making sure that the previously
loosened nut is re-tightened hard. To replace the nozzle just repeat the same procedure inserting
a new nozzle or a nozzle with a different diameter instead of the other.
Always empty the tank at the end of work and discharge the remaining inert in the gun to avoid
blocks in the passages and valves.
Handle with care all the tungsten carbide components because they are very fragile
