11. Care and Maintenance
1.
Warning
For the owner and user, it is mandatory to be aware of the safety relevance of speakers
that can be flown.
Note that the mains cables are delivered with varying connector options or with open
wires (mains side), depending on the country or order number.
The GRAVIS 15 system can exhibit signs of wear over the years, for example, from
mechanical strain, transport damage, corrosion, or improper handling. Remember that
flying speakers always impose a high safety risk.
Generally, perform a visual inspection of your speaker every time you suspend it or take
it down. In fixed installations, check the speaker for signs of wear at regular intervals.
When performing those checks, particularly look for deformations, cracks, dents, damage
to threads, and corrosion. Also check slings and lifts (e.g. shackles, chains, and steel
ropes) carefully for wear and deformation.
If as a result of these checks any uncertainty should arise with regard to safety or defects
are found, don’t use the speaker any longer.
Inspection regulations may vary depending on application and country of use. Observe
all applicable regulations; when in doubt, contact the local authorities.
Many countries require regular inspection of mounting components and accessories. An
additional annual inspection is typically required to be performed by a technical expert.
Moreover, a legally certified or official authority must perform a detailed inspection
every four years.
Therefore, be sure to maintain an inspection log. Enter the values determined for each
speaker and accessory during the periodic checks into this log. This way, relevant data
are always at hand in case of inspection. The log should also document maintenance
measures and inspection intervals and contain parts lists.
2.
The Polyurea synthetic coating used by KLING & FREITAG is impact proof and highly
resistant. We recommend using protective coverings or transport cases to help avoid
damaging the paint in case of continuous mobile use, etc.
3.
To replace the filter foam, send the front grille incl. foam to KLING & FREITAG GMBH.
Upon payment for expenses, the grille with the new covering will be returned.
