• 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 hydraulic oil (HLP 32). 9 litres of HLP 32 are re-
quired.
• Raise the lift approx. 1 m by pushing the operat-
ing lever (9). The lift rails can be lifted at different
times!
• Plug in the lifting arm bolts and provide with safety
rings.
• Push the operating lever forwards and raise the lift
to its uppermost end position.
• Push and hold the operating lever for another 60
seconds so air can escape from the system and
the overflow procedure equalises the lift to each
other.
For first commissioning, it is normal to have a differ-
!
ent start up and a large "shaking" in the uppermost
position. Air trapped in the system must be com-
pletely 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 upper range.
• After commissioning, the sticker (first filling) can be
removed.
