GENERAL SET-UP INSTRUCTIONS

ALPHA SERIES USER MANUAL V1.0

DATE: 14/01/00 18:27

• Do not allow inexperienced persons to handle X-BOW flying systems. Installation

personnel should be trained in loudspeaker flying techniques and should be fully

conversant with this manual.

• Ensure that motor hoists, hoist control systems and ancillary rigging components are

currently certified as safe and that they pass a visual inspection prior to use.

• Ensure that public and personnel are not allowed to pass beneath the system during the

installation process. The work area should be isolated from public access.

• Never leave the system unattended during the installation process.

• Do not place any object, no matter how small or light, on top of the system during the

installation procedure. The object may fall when the system is flown and is likely to cause

injury.

• Secondary safety steels must be installed once the system has been flown to the

operating height. Secondary steels must be fitted irrespective of the local safety standards

applicable to the territory.

• Do not fly the system over areas to which the audience has access.

• Ensure that the system is secure and prevented from pivoting about the motor hoist. Avoid

any form of dynamic loading to the assembly.

• NEVER attach any item to the X-BOW other than the NEXO X-BOW accessories.

• When flying outdoor systems ensure that the system is not exposed to wind or snow loads

and is protected from rainfall.

• The X-BOW requires regular inspection and testing by a competent test centre. NEXO

recommend that the system is load tested and certified annually or more frequently if local

regulations require.

• When de-rigging the system ensure that the same duty of care is given to the procedure

as for the installation. Pack X-BOW components carefully to prevent damage in transit.

• Correct training is fundamental to safe practise when working with loudspeakers flying

systems. NEXO recommend that users contact local industry associations for information

on specialist course. Information for UK and International training agencies can be

obtained by contacting:

• The Production Services Association (PSA),

School Passage,

Ground Stack Safety

Statistically, many more injuries occur due to unstable ground stacked PA systems than those

associated with flown systems. There are several reasons for this fact, however the message is

clear:
