sed air distribution network.
Do not apply excessive force or inadequate tools for maintaining and cleaning the unit. Some
repairs must be done with special tools on some occasions.
In these cases, you must contact the Customer Service of SAGOLA. Any handling of this product
by non-authorised personnel would render the warranty null and void.
The unit must be overhauled on a periodic basis to check the status of its components and
replace these when they are not in perfect condition.
IN ORDER TO OBTAIN THE BEST POSSIBLE RESULTS, ALWAYS USE ORIGINAL
SPARES. ENSURE TOTAL INTERCHANGEABILITY, SAFETY AND OPERATION.
11.1. Changing the self-adjusting Packing gland
The needle gaskets that form part of the packing gland are gun components that should be
replaced when malfunctions occur or when there is a loss of air tightness.
Gun head packing gland: In order to replace the packing gland, remove the product regulator and
extract the product needle and spring fitted with its stop. With a 13 mm fixed wrench, remove the
packing gland to be replaced. Replace the packing gland and reassemble in the reverse order.
Packing gland of the air valve: In order to replace the packing gland, remove the product regulator
and extract the product needle and spring fitted with its stop. With a 9 mm Allen wrench, remove
the guide box, extracting the valve spring, the valve and the bushing support. With a 6 mm Allen
wrench, remove the packing gland and extract the gasket. Replace the packing gland and the
washing support gasket (supplied in the specific kit) and follow the reverse procedure.
