Inspection and preventive maintenance

How to do preventive maintenance

Inspect the system before any deployment and after any corrective maintenance operation.
Perform preventive maintenance at least once a year.

Rigging and hardware

Perform the

Rigging part inspection

(p.27) on each rigging part.

Use the

Mechanical system overview

(p.29) to identify critical parts of the system and apply the specic checks

described in the

Inspection references

(p.32).

If any parts are damaged, contact your L-Acoustics representative for further instructions.

Acoustics

Perform the

Enclosure check

(p.33).

Perform the

(p.35) to detect any degradation in sound quality.

If necessary, refer to the

Corrective maintenance

(p.68) section for speaker repair kits and maintenance instructions.

Rigging part inspection

About this task

For critical rigging parts, use the

Inspection references

(p.32) for comparison and specic manipulations.

The term "rigging part" comprises:

• lifting accessories such as clamps and shackles
• rigging accessories such as rigging frames, rigging interfaces, and brackets
• fasteners used for assembling two products together such as ball-locking pins, rigging axes, rigging screws, threaded

knobs, and safety pins

This inspection procedure covers only L-Acoustics products. To inspect other products that are part of the lifting chain,

refer to the manufacturer's instructions.

Prerequisite

Perform the inspection in a well-lit environment.

Procedure

1.

Check that the rigging part is present.

2.

If applicable, disassemble the rigging part from the enclosure or the rigging accessory.
Check that the tethers are intact and safely secured.

3.

Inspect the part from every side.
Compare with the

reference pictures

.

Check for:

• corrosion
• wear and cracks
• bends and dents
• holes
• missing safety cues
• missing identication labels
• missing or loose fasteners
