4.11. Hyrdaulik connection for rotodent
The folding ROTODENT DJ / DP / DTEK / DMAX is a machine with double effect hydraulic installation to limit the overall transport
dimension.
Make sure that the pin link, the eventual quick couplings of the tractor as well as the safety brakes are in good working order and
in their proper seats.
Now connect the two quick couplings of the hydraulic circuit to two clamps of the tractor(it is necessary a pressure of 160÷190
bar). Follow the direct lines from the cylinders to the tractor.
At this point the implement is still laying on the ground, connected to the tractor, with the 3-point linkages and the hydraulic
connections coupled, Make sure that no other person is close to the implement; from the tractor it is possible to act on the
lifting device and lift the equipment for ~50 cm. from the ground.
4.11.1. Blocking system with cable
Make sure that the string A of the safety device reach directly your driver's seat and that they can be controlled without any
difficulty. Now we are ready for the opening and closing operation.
OPENING
a) Act on the hydraulic distributor lever which closes the
equipment, until the end stroke is reached.
b) Stretch the string A which lifts the two safety hooks B.
c) In order to open the equipment act slowly on the
hydraulic distributor lever, proceed without any jolts until both the two halves of
the harrow are in horizontal position.
CLOSING
a) Check if the harrow is in the position "FIXED or FLOATING DOWN", in this case you must
take away the two pins A and replace in hole B or C (see paragraph 5.7)
At this point act on the hydraulik distributor lever which closes the equipment and proceed to
the complete closing manoeuvring until the two moving parts ofo the harrow are both coupled with the two top
safety hooks B.
b) Loosen the hold on the strings.
c) Act on the hydraulic distributor lever which opens the equipment until the two top safety
hooks B will move. In this position, a further non-coordinate operation of the
distributor lever not produce any particular movements.
Perform some steps to open and close the equipment, always very slowly and always making sure that no other person is close to
your operating area, ensuring that the hydraulic system is completely full.(~ 4 litres).
The hydraulic pipes must be kept
far from any moving component.
Every time you use the machine,
check the pipes and the fixing
devices of the pipe fittings for their
conditions. The repairs must be
carried on only by qualified
personnel using only ALPEGO
original spare parts.
During the closing phase, make sure that the power take-off (PTO) is free of any type of braking.
