5.2 - MOUNTING THE CARDAN TRANSMISSION SHAFT
The mounting, disassembling or possible other interventions on the
transmission shaft must be carried out with the engine switched off and
with the starter key removed from the tractor’s control panel.
USE TRANSMISSION SHAFTS WITH CE CERTIFICATION. OBSERVE THE REGULATIONS
CONTAINED IN THE USE AND MAINTENANCE BOOK-LET PROVIDED BY THE SHAFT
MANUFACTURER.

The cardan transmission shaft
must work with the 2 COAXIAL drive
outlets (PTO) or, should this not be
possible, with the PARALLEL axles.
In this case the angle of the joint
MUST NOT EXCEED 15°.
Definition of the length
Set the 2 drive outlets (PTO) perfectly on the same axis and measure the distance “D” between their
grooves. Length “L” of the cardan transmission shaft (refer to the picture) to be deployed, measured
between the 2 stopping pawls and with joint closed, must bei 25÷40 mm lesser than distance “D”.
Using the cardan shaft too much
short can cause the breach of it,
with serious damages to the
sprayer and/or to the tractor, and
dangerous for the persons.
Using the cardan shaft too much
long cause a push on the two PTO,
that it can cause huge mechanical
damages both to the tractor and to
the sprayer.

AGITATION
9
The
hydraulic
and the
pneumatic
circuits mounted inside the tank, allow to realize
a double
agitation system
: with the pump water and with the fan air,
at the same time
. The pneumatic circuit
can be excluded, when the products used have a quite strong foaming effect, by closing the piston
cock, mounted over the tank. When that cock is opened again, check that the air outlet holes aren’t
obstructed.
.
It is advised however to also use always the pneumatic agitator, adding to the
mixture, if necessary, a antifoam product.
Before starting the treatment it is essential to agitate the mixture in the tank, re-
circulating it completely for as long as it takes to make it homogeneous.
The piston cock mounted over the tank have to be open. This operation is of main
importance, in order to get a uniform distribution of the active principle on the
whole vegetative surface to be treated.
Should the activity need to be interrupted during a treatment with the sprayer, keep the agitator activated
until the treatment is resumed. Should this be stopped and deferred to a later stage, the mixture that
has remained in the tank must be
agitated again
properly.
THE MIXTURE AGITATION HAS TO BE CARRIED OUT WITH THE POWER TAKEOFF RUNNING AT
A RATE OF AT LEAST 500 r.p.m..

OPERATING PROCEDURES

Before using the atomizer fill the circuit-washer tank (if provided) and the hand-
washer tank with clean water.
10.1 - OPERAZIONI PRELIMINARI AL TRATTAMENTO
•
The operator must:
a
. Ascertain that the condition of the crops, the progress of the disease or the need for its prevention
actually justify the treatment to be applied.
b
. Be aware of the meteorological conditions forecast for all the time necessary for carrying out the
treatment.
c
. If possible, avoid carrying out the spraying in strong wind conditions or when one detects that
the sprayed mixture disperses away from the target crop (drifting). It is advisable to suspend the
treatment when the wind speed exceeds 3 m/s (10 km/hour). Should it be imperative to operate
anyway, the following suggestions are made:
•
reduce the distance of the target from the spraying points, even if detrimental to the quality
of the spraying
•
increase the dimension of the droplets, suitably adjusting the machine.
