Fill And Vent The Hydraulic Systems; Commissioning; Changing The Assembly Location - ATT Nussbaum HYMAX 4000 PH Série Manuel D'exploitation

Installing the push button
The mounting base and buttons
have clearly visible reference
marks so that the engagement
process is easy and intuitive.
The electrical
contacts and
LED lighting ele-
ments are installed on the mounting
base by snapping them into place.
Operation of the middle contacts is standard on
pushbuttons without illuminated display, on/off
pushbuttons, mushroom-type pushbuttons and se-
lector switches.

Fill and vent the hydraulic systems

The lift is factory pre-installed; meaning the hoses
and pipe connections are properly assigned.
Finally, check the power connection, check for
correct hydraulic oil in the proper volume and
leak-tightness of the connection when setting up
the lift.
If the hose connections are still open, e.g. for the
purposes of hose extension, then air may be en-
trapped resulting in start up problems or challenges
with smooth running.
Check and ensure proper allocation of hose con-
nections.
This procedure must always be completely car-
!
ried out. This means, first fill and then vent.
Correct method of filling and balancing (lift with
HyperFlow system):
• Close the emergency discharge screws „N1" (14)
and „N2" (15).
• Push the o „Lift" button to move the lift upwards
without a load to the maximum height.
• Continue holding the
the „Overflow procedure". Oil flows from the hy-
draulic pump through the command and down-
stream cylinders and back into the tank.
• After releasing the o „Lift" button, the lift lowers a
few millimetres and closes the overflow openings.
• The system is now vented and smooth operation
can happen.
• The lift now has its normal operating function.

Commissioning

i Before commissioning, a single safety inspection
must be done (use the "single safety inspection"
form).

o „Lift" button. This starts
If the lift set up is done by a specialist (factory
trained assembler) then he can also do the safety
inspection. If the set up is done by the operating
company then a specialist must be tasked with the
safety inspection. The specialist confirms seamless
operation of the lift on the set up protocol for single
safety inspection and releases the lift for use.
i After commissioning, the set up protocol must
be completed and sent to the manufacturer.

Changing the assembly location

To change the assembly location the pre-conditions
must be met according to the assembly guidelines.
The location change is to be done according to
the following sequence.
• Move the lifting stage upwards to approx.
1,000 mm.
• Loosen and remove all hose covers.
• Loosen base plate anchors.
• Lower the lift to the lowest position.
• Disconnect power.
• If necessary, disconnect the hydraulic lines on the
operating unit only, and seal them off with blind
stoppers.
• If necessary, suction off the hydraulic oil.
• Transport the lift with the unit to the new set up
location.
• Assemble the lift according to the procedure
during assembly and anchoring before first com-
missioning.
Use new anchors. The old anchors are
no longer fit for purpose!
i Before re-commissioning, a safety inspection
must be done by a specialist (use the regular
safety inspection form)
