Lifting Arm Assembly; Lifting Arm Alignment; Latches - ATT Nussbaum POWER LIFT HF 3S 5000 Manuel D'exploitation

First filling without sticker.
Required oil volume, 14 (HLP 32).
9 L for system and 5 L for hoses and cylinders.
• After setting up the electrical connection to the
lift, the hydraulic system can be filled.
• Loosen and remove the plastic part of the oper-
ating lever (9) of both Allen screws (10).
• Loosen and remove the unit cover.
• Unscrew the oil filling opening (11).
• Fill with 9 L of hydraulic oil (HLP 32).
• Raise the lift approx. 1 m by pushing the operat-
ing lever (9).
• The lift rails can be lifted at different times!
• Hang in the lifting arms and secure them (see
4.9).
• Push the operating lever (9) forwards and raise
the lift to its uppermost end position.
• Now fill the oil tank with 5 L hydraulic oil (HLP 32)
• Afterwards hold the operating lever another
60 seconds so air can escape from the system
and the lift rails can be equalised by the overflow
procedure.
For first commissioning, it is normal to have a dif-
!
ferent start up and a large "shaking" in the up-
permost position. Air trapped in the system must
be completely removed first.
• Afterwards lower the lift to its lowest position. Pull
the operating lever (9) and hold it until the lifting
arm is completely lowered.
The oil level should be approx. 30-40 mm below
!
the oil fill opening. Do not fill the oil tank up to
the upper edge, as otherwise during lowering
the oil return line can pull oil out of the line and
afterwards result in a very slow lifting at the up-
per range.

Lifting arm assembly

Hang in the standard lifting arm and then place an
acid-free multi-purpose grease into the joint bolts
(12) in each case from above into the hole and
then insert the enclosed locking ring.
The lifting arm bolts must be secured
on both sides as otherwise a reliable
connection is not given between the
lift rails and lifting arm.
See to it that the lifting arm blocks (20) are rat-
!
cheted in after the vehicle has been accepted.

Lifting arm alignment

After lift assembly, it may be the case that the lifting
arm is at the lowest position on the base plate (2)
and is difficult to move.

14 Set screws
There is an option of setting two set screws (14) on
the bottom of the lift rails to a certain height so the
carrier arms are free and are easier to move.
8.4

Latches

Attention: After the lift has been installed and
!
if necessary (at least during the annual main-
tenance), the function of the latches must be
checked:
After mounting the lift and before the first move-
ment of the carriage, check that the latches are
free to move and the adjustment of their position
relative to the carriage.
