RIB RAPID S Mode D'emploi page 37

EMERGENCY RELEASE
Carry out only after power supply to the motor has been interrupted!
In the event of a power supply failure, release the gearmotor, so that you can move the boom
by hand.
To do so, use the RIB key supplied and turn it in the clockwise sense, until the stop is reached
(Pic. 12).
By doing so, the barrier boom works independent from the gearmotor and it can be moved
by hand.
When power is supplied again, turn the key counterclockwise strongly until you block it.
MAINTENANCE
To be undertaken only by specialized staff after disconnecting power supply.
After every 100.000 cycles check:
- boom balance (see the paragraph "ADJUSTING THE BALANCING SPRINGS");
- the tightness of the release knob (see the paragraph "EMERGENCY RELEASE");
- the tightness of the boom holding attachment and the implantation of the boom (see the
paragraph "ASSEMBLING THE BOOM");
- the wear on the mechanical stops and the limiti switch setting (see the paragraph "LIMIT
SWITCH SETTING").
- Grease the bearings of the boom carrier shaft and the threaded spring guide bar.
The described maintenance is vital for the corrected operation of the product in the time.
