4.5CARDAN SHAFT

In some models this is supplied on request. The cardan shaft must bear the CE mark.

It must always have its own instructions that must be followed scrupulously and it should come with a cover bearing the mark, integrated in every part. You should have previously checked the length to avoid:

=if it is too long, DANGEROUS THRUST ON THE PUMP SHAFT

=if too short, the POSSIBILITY OF DANGEROUS BREAKAGES

FIG. 6 FIG. 7

THE MINIMUM OVERLAP OF

THE TWO TELESCOPIC

TUBES MUST NEVER BE

LESS THAN 1/3 OF THE

LENGTH OF THE TUBES.

The power that can be transmitted by the cardan shaft must be at least equal to that required to run the atomiser.

These power ratings are indicated in tables N° 14A-15A-16A (pages 37-38-39).

a)Hook any safety chains to solid anchor points

b)Check that the button or ringnut “E” (FIG. 6) is correctly engaged and blocked both on the pump side and on the tractor side.

c)Don’t exceed an inclination of 30° in any direction for any reason

d)With the machine stopped, periodically grease the spiders and the pipes, keeping the connecting zone particularly clean.

e)Avoid letting the end of the cardan shaft come into contact with the ground with the machine stopped; use the relevant support on some versions for this, if your machine has no support, hook the external safety chain to a part of the frame of the machine (ex. control unit support).

NEVER USE THE CARDAN TRANSMISSION IF THE FOLLOWING PROTECTIVE COVERS ARE MISSING:

-TRACTOR POWER-TAKEOFF PROTECTIVE COVER

-CARDAN SHAFT PROTECTIVE COVER

-FIXED PROTECTIVE COVER ON THE PUMP SHAFT

4.6PUMP

When using the pump scrupulously observe the instructions in the enclosed handbook supplied by the manufacturer.

The pump can be identified by the ratings plate on the same; the main data on the pressure and delivery are easy to find on this plate.

Normally the pumps mustn’t exceed 550 RPM; a higher speed won’t improve performance but there is a risk of compromising the life and safety of the pump.

There is a safety valve on the pump, calibrated to prevent overpressure. Don’t tamper with this valve for any reason and don’t block or obstruct the pipes connected to it in any way.

4.7SUCTION FILTER

The sprayer is fitted with a suction filter with filter cartridges that have roughly a 50-gauge mesh, which is equivalent to a hole of 0.4 at 0.35 mm.

An efficient filter lets the sprayer work properly.

You should periodically check that the filter cartridge is clean, this check should be done more often if there are impurities in the liquid.

To inspect the filter cartridge wear rubber acid-proof gloves as the liquid in the filter can come into contact with your hands when you open the filter.

Don’t perform this operation with the pump running as the depression produced blocks the cover preventing the removal.

Before removing the cover of the filter, make sure that the same is isolated from the tubing by unscrewing the relevant rear valve (FIG. N°8).

After washing the cartridge, reassemble the cover making sure you connect the same to the circuit again, using the valves described above in the opposite order.

WARNING!: Don’t disperse the washing residues in the environment!!

Don’t use the sprayer without having consulted the enclosed handbook.
