The hovering position without load must be adjusted with each operation.
The hovering position of the lifting device must be adapted to the weight of the vacuum head.
A valve (2) in the tube support cylinder is used to adjust it.
When you apply the vacuum head to the load a valve is fully opened by a plunger and the valve rod in the
vacuum head. The load can be sucked and lifted.
Adjustment:
Turn the adjustment screw (1) at the operating unit (accessible from the bottom).
Turn clockwise (direction of arrow)
➔
Valve becomes opened.
Turn counter-clockwise
➔
Valve becomes closed.
The farther the valve is opened the lower the device hovers.
When the valve is closed totally the device bounce up abruptly as soon the blower is switched on!
•
Place the vacuum head directly above the load/kerb stone.
•
Press the regulator lever (1) down. The lifting tube descends and
the vacuum head lowers.
•
Apply the vacuum head to the load. Distribute load evenly.
•
Slowly push the regulator lever (1) upward. The device attaches
to the load.
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.
