13.4. REPLACEMENT OF AIR FILTERS
LM-C300 S/P includes one air filter on the top of the laser system.
They must be replaced periodically with new filters (once a year). Only elements supplied by HITACHI or
its distributors must be used.
To do this, detach the filter which is fastened along its edge and reattach it in the same way.
