HOLE FOR
SAFETY
CHAIN
Cardan shaft: for the instructions concerning
to its installation and adjustment consult to its
use and maintenance manual.

Pull-type (fig.13): the operator must move
the tractor slowly to a position where the
joints can be easily aligned (
1 - fig.13 ).
IMPORTANT
The holes in the tractor attachment must be
aligned with those on the rake attachment
with maximum care and attention.
When the tractor is near the rake hitch, turn
the lever on the bearing jack (
2 ) to raise or
lower the rake hitch and bring it parallel with
that on the tractor. You can then insert the
locking pin (
3 ) through the respective holes in
the attachments, as shown below, and
secure it in place with the respective safety
pin (
4 ).
Next, turn the lever ( 5 ) on the bearing jack to
raise the latter as high as necessary to move
it from its position to that required for trailing
the rake.
To move the jack (
fig.13 ): remove the R pin
( 6) , take out the handle pin ( 7 ) and take the
jack out of its housing ( 8 ). Next, turn the jack
counter-clockwise ( 9 ) as illustrated and re-
insert it in its housing. Insert the handle pin in
its new housing and fasten it with its
respective R pin.
Note: near the tow hitch there is a hole
where to connect the safety chain, which
must be successively fastened to the tractor.
The application of this chain is not mandatory
in Countries members of the European
Union, however it is in other Countries, as
U.S.A..
C3 Installation and adjustment of cardan shaft

Installation: strictly observe instructions
relative to installation indicated in its own use
and maintenance manual.
IMPORTANT
Before installing the cardan shaft, verify that
this has the requisites required for the type
and power to transmit according to the rpm of
the PTO. If required, verify also the tractor
use manual
.
Should this not be used, is saying not
installed on the PTO of the tractor but only on
the windrow rotary rake one, lay the cardan
shaft on the support located on the
mounted
type or on the towing bar of the pull-type .

Adjustment: the cardan shaft (both provided
with the equipment and sold as accessory)
has a standard length. So it must be adjusted
to the tractor where the windrow rotary rake
is installed. For this operation, proceed as
follows:
-
remove protection devices from the
cardan shaft;
- remove the two parts that make up the
shaft and join a part to the windrow rotary
rake PTO, by clicking the spring safety
pin and the other part to the tractor PTO,
by clicking the spring safety pin as well;
-
place the two parts of the cardan shaft
beside and find the minimum sliding
length (
L ). Should the shaft be too long,
shorten the two external plastic protection
pipes, which must have the same size,
and then the internal metallic ones.
Smudge the cut parts and lubricate the
internal parts.
IMPORTANT
When the cardan shaft is pulled out at its
maximum, the two pipes must overlap for
at least 15 cm. When it is inserted at its
maximum, the minimum gap allowed
must be 4 cm.
- remove the two parts of the cardan shaft
from their connections (on the tractor and
windrow rotary rake) and assemble the
