1- INTRODUCTION
It is essential to read and follow the instructions and
recommendations in this manual before operating the seed
drill or precision planter ARGO. Careful reading enables
maximum operator eciency, prevents accidents and damage,
and increases the planter’s capacity and life expectancy.
Please ensure that this manual has been read by any person
involved in performing operational tasks, (including
preparation, dealing with mechanical problems and
supervising the machine), maintenance (inspection and
technical assistance) and transport.
For your safety, please follow these technical safety
instructions as SOLÀ will not be responsible for damages
caused by not observing the information provided.
In the rst chapters you will nd the Technical Characteristics
and Safety Instructions. Basic concepts that are required
to operate the machine are explained in the Starting,
Adjusting and Maintenance sections.
The last part of this manual consists of Dosage Tables,
detailed by all types of seed, fertilizer, micro granular
fertilizer and micro granular pesticide.

2. SAFETY INSTRUCTIONS
2.1 SAFETY SYMBOLS
En este manual encontrará tres tipos de símbolos de seguridad y de peligro:
TO WORK MORE EASILY
WITH THE PLANTER.
TO PREVENT DAMAGE
TO THE PLANTER AND
OPTIONAL EQUIPMENT.
TO PREVENT PHYSICAL
INJURY.
On the machine you will nd the following warning
pictograms:
Read the instructions carefully and observe the
safety advice given in the operating manual.
During the coupling maneuver, stay away from
the rear part of the tractor. Check nobody
stands in the operational area of the telescopic
folding parts. Risk of serious physical injury.
While maintaining or repairing the planter,
stop the tractor’s engine and prevent it from
starting. The ignition key must be removed.
Never stand under the sowing equipment
or swivel area of the machine’s extension tine
coulters.
Risk of serious physical injury.
Risk of being crushed when working under the
machine, please secure the machine to prevent
this risk. Risk of serious physical injuries.
It is forbidden to ride on the machine during
operation. Risk of serious physical injuries
caused by falling.
Danger of infection from escaping hydraulic
uid at high pressure! This can inict serious
injuries with potentially fatal consequences
if it passes through the skin and into the body.
Keep the hose lines in good condition. Risk
of serious physical injuries.
Never stand under the track markers nor inside
their action area. Risk of serious physical injury.
Coupling point for loading and unloading the
machine by crane.
Do not exceed maximum load
The parts signaled with this pictogram should
be kept in good condition and greased.
Kg. Max.

2.2 GENERAL SAFETY INSTRUCTIONS
- Before starting the machine, please check the
machine is in good condition for work and
is safe for road use.
- Check that visibility is clear around the
machine and there is no person in the
working area.
- In thoroughfare, please observe trac signs
and regulations.
- It is forbidden to ride on the machine or climb
into the machine when it is running.
- Before using the machine, the user must
be familiar with all operating elements.
- Please be extremely careful when coupling
and uncoupling the machine to the tractor.
- Never leave the tractor’s driver’s seat while
the machine is in operation.
- Do not deposit external elements inside the
hopper.
- When maintaining the hydraulic system of the
planter, make sure that it is depressurized and
the tractor’s engine is o.
- Please regularly check the condition of the
tubes and hosepipes in the hydraulic system.
These parts age naturally and their life should
not surpass 6 YEARS. Please replace when
necessary.
- Before transit with a machine with folding
frame coupled to the tractor, check that the
frame is completely folded.
- When raising the planter, the front axle
is unloaded. Ensure that the machine has
enough load to prevent it overturning. At this
time you must ensure that the condition
of both the steering and the brakes is optimal.
- During transit with the raised planter, block
the lowering switch. Before leaving the
tractor, lower the planter onto the ground
and remove the tractor’s starting key.
- Always use enough supporting elements
when maintaining the machine in a raised
position to prevent the machine from
lowering or falling.
- Before starting to plant a eld, evaluate the
risks coming from the terrain: pronounced
slopes, possible contact with high-voltage
overhead lines due to an uneven ground
or due to the position of the movable
or folding parts of the planter.
2.3 LOADING AND UNLOADING INSTRUCTIONS
THESE OPERATIONS SHOULD BE PERFORMED
ONLY BY QUALIFIED AND EXPERIENCED
PERSONNEL.
LOADING AND UNLOADING THE MACHINE
MUST BE PERFORMED, IF POSSIBLE, USING
A BRIDGE CRANE.
WHEN THE PLANTER IS DELIVERED,
IT SHOULD BE IMMEDIATELY CHECKED
TO DETECT POSSIBLE DAMAGES DURING
TRANSPORTATION OR MISSING PIECES. ONLY
THE IMMEDIATE REPORTING OF THIS TO THE
DELIVERER WILL RESULT IN COMPENSATION.
