This symbol is used throughout this manual wherever recommendations
are made concerning the safety of others, or good machine operation.
These recommendations must be made known to all machine operators.
PROPER USE OF THE MACHINE
The weighing unit must only be used for work for which it has been designed:
- Indication of the weight contained in the machine with, for the programmable version, the
possibility of programming animal rations.
The weighing unit must not be used for commercial transactions.
Proper use of the machine also means:
- following operation, maintenance and repair recommendations given by the manufacturer,
- using only spare parts, equipment and accessories as designated by the manufacturer.
Theweighingunitmustonlybeused,maintainedandrepairedbycompetentpersonswhoarefamiliar
with the machine specifications and are aware of any danger involved.
The operator must observe current legislation concerning:
- accident prevention
- work safety
1. GENERAL
1.1 WARNING

1.2 GENERAL SAFETY RECOMMANDATIONS
Beforeoperatingthemachine,alwaysensurethatthe machine complies with work safety regulations.
GENERAL
1. Safety decals with recommendations to prevent accidents are placed on the machine.
2. Before carrying out work, ensure that the weighing unit is turned off.
3. Portable telephones can have a harmful effect on the working of the weighing unit.
USE
Before connecting the weighing unit to the tractor:
- check that the electric plug is clean and free from dirt,
- check that the electric circuit is correct.
MAINTENANCE
1. Disconnect from the power source before any work is done on the electrical system.
Before any electric welding is carried out on a machine that is attached
to the tractor, disconnect the tractor alternator and battery. Connect
the earth lead as close as possible to the part to be welded. Never
connect the earth to the chassis if the hopper is to be welded. If this
advice is ignored, then irreparable damage can be caused to the sensors
which connect the hopper and chassis.

1.3 OPERATING CONDITIONS
1.3.1 MACHINES WITH CHASSIS
Type of machine: EUROMIXI,II and III,allmodels
ALTOR 9050 and 11050
TURBOMEL7050, 9050 and 11050
Before responding to the message ‘Is the machine empty?’ (IND360) or “--0--” (IND900), ensure
that:
- The tractor engine is switched off.
- The machine is horizontal lengthways and widthways at the transport height; if not, refer to the
section on technical characteristics and tow bar adjustment in the user instructions.
- The machine is not exposed to strong wind.
- The transmission slides effortlessly.
- The chassis is well isolated from the body (check for stray product or foreign bodies).
- The machine’s components (arm, grab and tailgate) are in the idle position (see user instructions).

1.3.2 MACHINES WITHOUT CHASSIS
Type of machine: ALTOR 4560, 6070, 7560 and 8060
ATHENOR 6070, 7560 and 8060
ALTOR and ATHENOR 4560, 6070 & 7560
Before responding to the message ‘Is the machine empty?’ (IND360) or “--0--” (IND900), ensure
that:
- The tractor engine is switched off.
- The machine is horizontal lengthways and widthways at the transport height; if not, refer to the
section on technical characteristics and tow bar adjustment in the user instructions.
- The machine is not exposed to strong wind.
- The transmission slides effortlessly.
- The machine’s components (arm, grab and tailgate) are in the idle position (see user instructions).
- The brakes are off (parking and service brake) (see user instructions).
Sufficient clearance is required between the brake shoes and the drum;
any rubbing may cause incorrect weighing.
Adjusting the levelling sensor
- Set the body to height B from the ground and the towing eye bolt to heightA, adjust the screw (1) to
position it opposite the sensor, then set the detection distance to approximately 3 mm (maximum
4 mm). The sensor indicator should then light up.
- Tighten the screw and the sensor onto their respective mountings.
- Checkthebodyheightsetting.To do this, lower thebodytotheground,thenraise it until the indicator
lights up and measure the body height. This must be equal to height B ± 10 mm.
If the measured distance is not correct, repeat the adjustment operation.
