Roundbaler DIAVEL 630
– DIAVEL 630 CUT
USE AND MAINTENANCE MANUAL - 32 -

Uncouple the two parts of the PTO shaft

Keep the two parts of the PTO shaft one
beside each other simulating the moving
position

Make a mark on the pipes of internal and
external protection to indicate the length
(X) where the pipe has to be cut.

Remove the protection pipes of each half
of the PTO shaft

Shorten the protection pipe of the length
(X).

Set the cut piece next to the pipe of
internal protection.

Shorten the inside protection pipe of the
same length (X).

Shorten the transmission pipes to the
necessary length. Even when the
transmission is not under rotation, the
telescopic pipes have to keep a suitable
overlapping to avoid blockages.

Perpendicularly cut the inside and outside
profiles at the same length (X)
– the parts
of cut pipes can be used as samples

Deburr and clean the cut profiles

If the outside profile of the PTO shaft is
equipped with lubricators, the holes to
enter to the lubricators have to be made
once again.
In any case, before using the PTO shaft, it is
necessary to follow these instructions:

Make sure the PTO shaft is suitable to
transmit the power required by the round
baler (see technical data on the
instructions manual for the PTO shaft). In
case of doubt, contact the Service Center
of the manufacturer.

Before starting to work, verify that all
protections are in a perfect status and that
there are the suitable security chains. Fix
these chains one to the machine and the
other to the tractor, to avoid that the
protections rotate with the PTO shaft.

It is compulsory to keep efficient the PTO
shaft and the machine protections, do not
use PTO shafts with ruined protections or
worse missing
5.2.4. Automatic torque limiter
The PTO shaft has to have a torque limiter which
operates by interrupting the power transmission
when a torque peak occurs, over the set value.
During the intervention of the device, the power
transmission is interrupt
ed and it’s necessary to
stop the PTO shaft of the tractor
Only successively the connection of the PTO, the
power transmission will be restored.
DANGER
If it’s necessary to replace the torque limiter,
replace it with one of the same or equal
dimensions and calibration. Do not use
different limiters and do not tamper with the
limiter to avoid big damages to the machine
or/and to the operator.
CAUTION
Before inserting the PTO, make sure that the
rotation speed corresponds to the one
required by the machine (540 R/ min).
5.2.5. Hydraulic system
The round baler is equipped with an hydraulic
control. The working parameters must remain
within the following range:

Minimum pressure: 150 bar

Maximum pressure: 200 bar

Maximum delivery 40 liters/min

The tractor must have two hydraulic
double effect quick couplings ½" female
.
Connect all pipes with blue cap to the distributor
to use, to start the rear door. Connect all the
tubes with red and yellow caps to the distributor to
use to start the pick-up, the knives and the tray.

On one of the two pipes with the blue cap
there is a ball valve which blocks the flow.
Close the valve every time you intend to
operate on the rear door in order to avoid
accidental operation.
The pipes of the hydraulic system are SAE 100
R2AT type, whose technical features are listed in
the following table.

WARNING
In case of wearing or damage of the hydraulic
pipes, the oil at high pressure might go out
