Maintenance information
The
L-ACOUSTICS
®
LA-RAK Touring Rack
is a technical product designed for various, intensive indoor and
outdoor sound reinforcement applications. To fulfill such demanding conditions L-ACOUSTICS
®
has designed the
LA-RAK with high-grade and reliable components:
•
Aluminum and steel frames, rubber shock mounts.
•
Polyethylene sides.
•
LEXAN
®

Screws and rigging points resistant to oxidation.
However, in order to ensure product performance and safety, it is essential to frequently inspect the LA-RAK and its
internal components. These checks need to be done on a regular basis depending on the conditions of system use. The
testing procedure consists of three steps as described in section 7.2.

Check the quality of contact and locking action of all electrical sockets (PA-COM
®
, CA-COM
®

•
RK 9U rigging rails, ball locking pins, rear panels, and LEXAN
®

2.
Check the integrity of mobile and rigging parts (no signs of deformation, indents, or rust).
3.
Ensure that the locking mechanism of each spring-loaded safety, ball locking pin, and shackle operates normally.
Any component incorporating a part showing signs of defect must immediately be put aside and
withdrawn from use to be inspected by qualified service personnel.
