●
Slowly move the regulator lever (1) downward - "Lower".
The lifting tube descends and the vacuum head lowers with the
load.
●
Do not operate the regulator lever control abruptly, while you
firmly hold the handlebar (3), as this can cause the load to fall
off, because the vacuum suddenly vanishes.
●
Lower the load to the chosen position.
●
To land the load push the regulator lever down all the way. Tip
the valve control box a little and lift it off the load.
For further details see the attached operating instruction. Operating
