3.
When the alarms stop and the green lamp flashes, the load is securely attached and can be shifted and
manoeuvred as required. See photo above.
4.
The driver raises Skylifter and the load until they are unobstructed.
5.
The operator operates the Skylifter scissor lift system backwards and manoeuvres the load into the
desired position. NB: Consider how best to position/turning the load to bring it into the easiest
position for mounting.
6.
The driver drives the carrier to the work zone area and lowers the carrier's supporting legs so that it is
stable.
7.
The driver then carefully manoeuvres Skylifter and the load as close to the final position as he can
safely achieve. The driver then signals that the operator can take over.
8.
The operator carefully manoeuvres the load into place. When the load is secured, to release the
vacuum, the operator presses and holds down both buttons marked with a red circle for 3 seconds.
See photo above.
9.
The vacuum pumps shut off and the vacuum valve releases the vacuum on the suction pads. It takes
only a few seconds to release the load.
10.
When the suction pads have released the load, the operator manoeuvres Skylifter away from the
mounting area. The operator fully retracts the Skylifter's scissor system and signals to the driver that
he can remove Skylifter from the work zone.
Important: Check the following:
•
When attaching the load, the operator must check that the alarm sounds and the red lamp
flashes at the start. If this is not the case, the machine is defective. The machine must not be
used until the defect is located and rectified.
•
When the vacuum pumps stop, pressure should be -0.62 ±0.02 bar. See vacuum gauge display.
The pressure must be stable. It must not increase. If the pressure increases, the machine is
defective and must not be used until it has been repaired. NB: When a vacuum circuit is
defective, the pressure increases from -0.2 to 0 bar. The alarms are triggered at -0.5 bar.
