BOXER KING 5600 - Access to Hydraulic Parts

Service Manual 04/2010 Rev.B

 RIGHT: Oil flow reaches the side “A” of the
cylinder 4.5 through the valve Y5N. Oil in
opposite side “B” gets out and returns to
reservoir through the valve Y5B (Fig.52).
6.0.9 RISE AND DESCENT OF
ROBOTIC:
 RISE:
The oil flow reaches the side “B” of the
cylinder 5.5 through the valve Y4N making the
robotic lifting.
Oil contained in opposite side ”A”, returns to
the reservoir through all others valves.
 DESCENT: Oil flow reaches the side “A” of
cylinder 5.5 through the valve Y4B making the
robotic lowering.
Oil contained in opposite side “B”, gets out
through the valve Y4N and returns to reservoir
through all other valves (Fig.52).
6.0.10 DOUBLE MOVEMENTS:
Oil flow can reach simultaneously more valves
moving more cylinders and making faster
operations.
As soon as one or more cylinders reach the end
of their stroke, machine stops all movements
because the valves 0,5 or that one 4.1 open and
unload the oil to the reservoir.
6.1 ACCESS TO HYDRAULIC PARTS
The access to the hydraulic parts of the Boxer
King 2600 is more complicated compared to the
electric ones, because in some cases the
dismounting of many parts is required to reach
those defective.
The most important controls are those ones
concerning the different hydraulic pressures at
which each cylinder of the machine is working.
This controls allow to find out very quickly the
reason of any hydraulic malfunction.
Another of the purpose of this manual is to reduce
as much as possible the oil leaking during the
maintenance operation: this will allow to operate
on the machine in clean and safe condition.
Before approaching the hydraulic parts , the
following material needs to be prepared:
 2 oil containers: 1 for hydraulic oil and 1 for
gear oil.
 Oil absorber.
 Paper towels.
BEFORE APPROACHING THE
HYDRAULIC PARTS OF THE
MACHINE, DISCONNECT THE
MACHINE FROM ELECTRIC
SUPPLY.
IN CASE OF OIL LEAKING DRY
CAREFULY THE FLOOR TO
AVOID SLIPAGE.
IMPORTANT!
 HYDRAULIC ASSY: Remove the top cover
(Fig.122) and the whole assy is available
(Fig.126).
