Martin RUSH PAR 3 RGB User Manual page 10

1. Check that the rigging structure can support at least 10 times the weight of
all fixtures and equipment to be installed on it.
2. Block access under the work area.
3. Fold the legs of the mounting bracket together. Check that the rigging
clamps are undamaged and approved for the fixture's weight. Bolt a
rigging clamp securely to the bracket. The bolt used must be M12, grade
8.8 steel minimum, and fastened with a self-locking nut.
4. Working from a stable platform, hang the fixture on the truss and fasten
the rigging clamp onto the truss.
5. Secure the fixture with a safety cable as directed below.
Securing with a safety cable
Secure the fixture with a safety cable (or other secondary attachment) that is
approved for the weight of the fixture so that the safety cable will hold the
fixture if a primary attachment fails.
Loop the safety cable through the eye bracket on the fixture (arrowed in
illustration below) and around a secure anchoring point.
If a safety cable attachment point becomes damaged or deformed, do not use
the fixture. Return it to a Martin Service Centre for repair.
