Adjusting the hovering position with load

Turn the adjusting screw (2) to adjust the hovering position with
the load.
Caution: Do not confuse this adjustment with the hovering
position without load.

Turn screw clockwise
position will be lower.

Turn screw counter-clockwise
position will be higher.
Control lever (of operating valve unit) must not be on the position "Lift", for more than 90 seconds.
Because otherwise the blower could be damaged and fail, (all guarantee claims are void) and power is
wasted unnecessarily.
The hovering position with load should not be adjusted to the highest position of the lifting hose unit
because otherwise: the blower could be damaged and fail,
(all guarantee claims are void) and power is wasted unnecessarily.
•
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.
