SUGGESTED PREVENTATIVE MAINTENANCE
FOR
FOR AIR DRIVEN AIR AMPLIFIERS
The suggested maintenance schedule is intended only as a guideline. The operating conditions of the
amplifier, such as air drive pressure, air supply pressure, air outlet pressure, air cleanliness and actual
running time at pressure, combine for an almost infinite range of variable conditions and
all
directly
relate to the life of the amplifier and it’s components. Even the external environment around the
amplifier, such as dust and heat can affect the service life.
The following suggestions are based on average operating conditions and a 50% to 60% run time
factor for the amplifier. These times could be shorter or longer based on operating conditions listed
above
EVERY 3 MONTHS
Remove spool, remove spool O-Rings and clean spool. Place New O-Rings on spool and apply a
thin coat of grease
*
to the O-Rings and bore of the spool sleeve housing. Insert spool
gently back in spool sleeve, by working it in and not forcing it straight in.
Remove and check pilot tappets and the bonded O-Ring. Make sure the O-Ring is still attached.
If the tappet is damaged or the O-Ring is loose, replace the tappet.
Inspect muffler to make sure it is not coated with dirt and/or oil. Replace if necessary.
EVERY 6 MONTHS
Rebuild the Spool, Air and Gas sections and clean and inspect the check valve sections as well as all
major components for scratches or damage.
EVERY 12 MONTHS
Rebuild and clean the entire amplifier
* Recommended grease is a high temperature type, Kluber Lube, Polylube GA352P
