8. SERVICE and MAINTENANCE

Maintenance

Usually, your EAW Commercial loudspeaker will not require regular maintenance for

normal use. However, you can do several things to keep your loudspeaker in good operating and cosmetic condition.

Testing: Periodically test your loudspeaker for proper performance. A simple test is to play a CD through it using well-defined, articulate, wide-range program material. Listen to ensure all drivers are working properly and for any evidence of distortion or other extraneous sounds. Test at several volume levels: very low, normal, and high.

Mounting/Rigging: Any mounting or rigging hardware should be regularly inspected for security, wear, deformation, corrosion, and any other circumstances that may affect the load-handling capability. Immediately remove from service and replace any hardware whose load-handling capability may be compromised.

Cleaning: Cleaning the exterior of the enclosure will depend on the type of “dirt.” Dust, food spills, or similar contaminants can usually be removed with a cloth dampened with water, or a mild household cleaner. Avoid using any strong solvents as this may damage the finish. Turn the amplifiers off before cleaning.

Scratches or Dents in Wood Enclosures: Minor scratches on the enclosure can be painted over with an outdoor latex paint, or simply a colored in with a “Sharpie” or artist’s marking pen. More serious gouges or dents should be sanded out, filled with wood putty, and repainted. Touch-up paint in pints and quarts is available through EAW Commercial Technical Support.
