Cardan Instruction Manual!
The following recommendations do not in any way replace those
existing in the Cardan Manual. Consult it and respect all
instructions and safety recommendations contained therein.
SEMI-HOMOKINETIC
Homokinetic joint
Simple joint
If your cardan is SEMI-HOMOKINETIC (with only one homokinetic
joint on the tractor side), its shaft must be as close as possible to
the tractor's coupling shaft.
If your cardan is HOMOKINETIC (with two homokinetic joints), the
tractor hitch shaft must be (as much as possible) in the middle of
the space between the two joints.
•In the transmission simple joint (tank side), it is
recommended to work with angles that do not
exceed 16º at 540r.p.m. and the 9th to 1000r.p.m.
(See cardan manual).
•The homokinetic joint allows a maximum working
and rest angle of 70º.
•Always respect the cardan safety regulations and
existing warning labels. Keep them in good condition
or replace them if necessary.

ACOPLAMENTO INICIAL AO TRATOR
When you need to couple / uncouple the trailer to
the tractor, no one should be present in the area
between the two vehicles! This is considered a
danger zone!
NOTE: Before starting the coupling, make sure that the
trailer is on a level ground and that the parking brake
is properly on. If you have chocks, always make sure
that the trailer wheels are chocked before starting
the following procedures.
TRAILER COUPLING TO TRATOR
1º Align and move the tractor’s coupler towards the
coupler's device of the trailer’s drawbar.
2º Connect the drawbar’s safety chains to the
tractor;
3º Connect all trailer's hydraulic and pneumatic
hoses (if applicable) to the tractor's hydraulic
sockets;
Note: The tractor must be off;
4º Connect the plugs of the trailer electrical systems
to the tractor’s socket;
5º Operate the drawbar’s rest hydraulic cylinder in
order to level the coupling device with the
tractor’s coupler;
6º
! WARNING !
6º Slowly move the tractor in reverse until it aligns
the tractor's coupler with the coupler's device
of the trailer’s drawbar. When they are properly
aligned, proceed to the coupling.
7º Make sure you have completed the previous
step correctly and retract the hydraulic cylinder
from the drawbar to the operating position;
8º Remove the chocks from the wheels (if fitted)
and proceed to work safely by releasing the
hand brake / parking brake.
PEOPLE IN THE DANGER ZONE BETWEEN THE
TRACTOR AND THE TRAILER MAY BE CRUSHED OR
RUN OVER!
KEPP OUT ALL PEOPLE FROM THE DANGER ZONE WHEN TO
COUPLING / UNCOUPLING THE TRAILER;
NO ONE IS AUTHORIZED TO RAMAIN ALONGSIDE THE

1. Properly put the tractor’s brake on and then
switch it off;
2. Close the safety tap on one of the hydraulic
hoses on the drawbar;
3. Connect the two appropriate hoses to the
tractor;
If you experience difficulties connecting the hose
that contains the stopcock, first make sure that it
is closed and try to activate the quick attachment
valve, in order to depressurize the short link
present between the two elements. In doing so, it
should be easy to make the coupling.
4. After connecting the hoses to the tractor, open
the safety stopcock.
5. Before reconnecting the tractor, make sure to
complete the connection of all the other systems.
NOTE: Never disconnect the hoses from the tractor without

HYDRAULIC BRAKING SYSTEM
WITH 3-POSITION VALVE (WHEN APPLICABLE)
This hydraulic braking system is equipped with a 3-
position valve that allows the intensity of the braking
forces to be adjusted according to the load it carries
Therefore, before driving with the trailer empty, half
full or completely full, you can adjust the valve to the
corresponding position in order to adjust the braking
forces to the load you are carrying.
The connection of this system is guaranteed using two
hydraulic hoses that must be connected to the brake
valve and a line with connection to the oil tank of the
tractor's braking system.
Make sure that you connect this system correctly
each time you proceed to the trailer's coupling.
Always respect speed limits to not jeopardize your
safety and the safety of others.
1º Carefully bring the tractor to the tow boom in
order to engage, lock the tractor an turn of the
engine;
2º Connect the hydraulic hoses of the braking
systems ti the respective lines of the tractor;
When connecting, make sure that the quick
connection valves are free from dirt.
3º Start the tractor engine and teste the braking
system and check if the system works correctly.
NOTE: The braking system must be connected to the tractor on
the appropriate lines and it must not exceed 115 bar.
NOTE: Do not drive on
public roads if the
braking system is not
working properly or if
you detect any
anomaly that could
jeopardize the safety
of the vehicle or
people's safety!

HYDRAULIC SYSTEMS
HYDRAULIC BRAKING SYSTEM
(WHEN APPLICABLE)
The simple hydraulic braking system is installed, which
must be connected to the tractor, through the hose
that contains the ½ female quick valve, as shown in
the following diagram:
If you notice overheating in the brake drums, or if you
feel that braking is insufficient, you may need to adjust
the brake, especially after the first few runs.
For that, and only if your equipment is equipped with
adjustable handles, proceed to tighten / loosen the
adjustment screw in them (BIELLETTES) in order to
obtain the necessary looseness between the jaws and
the drum.

Long use of the equipment is likely to cause
considerable wear on the pads. In this
case, check if it is necessary to replace
them or if the tightening of the adjustment
screw on the handles is sufficient to
guarantee the braking effect. Check
"Brake / Jaw Adjustment".

HYDRAULIC SYSTEMS
HYDRAULIC BRAKING SYSTEM
3 POSITION CONTROL + ELECTRICALLY CONTROL VALVES
(WHEN APPLICABLE)
This system was specifically developed to assist the
user to easily adjust the braking pressure and without
leaving the tractor, according to the load it transports
on the trailer, from an electric control placed on the
tractor.
This way, with the help of the control, the driver can
change the braking pressures to:
0= EMPTY (35bar)
½= HALF LOAD (75bar)
1= FULL (115bar)
(MAX PRESSURE = 115 BAR)
