4./5. ATTACHING THE LOAD / HEIGHT ADJUSTMENT
ATTENTION!
- Do not underestimate the weight of the speaker.
- The attachment as well as the extension/retraction of the load should be
-
carried out by competent, i.e. technically and physically suitable personnel.
- Attentiveness and communication between the operators is essential.
- Always hold the extension tube with a firm grip
4.2
during the height adjustment.
-
Be prepared to tightenthe wing nut

immediately (e.g. should the load unintentionally slip)
We recommend that you first set the desired height,
secure it and then attach the load. If this is not possible,
a qualified person (P1) must hold the loaded extension
tube while another person (P2) handles the securing
elements safety hook

5. RETRACTION
- Careful handling of the extension tube maintains the telescoping, the load capacity
-
and safety of the installation.
- During maintenance work - always in unloaded condition - pay attention for possible
-
hazards (jamming, bumping, tipping over).
- For cleaning and maintenance, use a slightly damp cloth and a non-abrasive cleaning
-
agent.
