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
THE MINIMUM OVERLAP OF
THE TWO TELESCOPIC
TUBES MUST NEVER BEFIG. 6
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 mistblower.
These power ratings are indicated in tables N°
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).
f)For towed mistblowers with a steering drawbar, be very careful not to lift the
arms of the elevator too high to prevent the cardan shaft touching parts of the drawbar.
l)For towed mistblowers, avoid very tight steering circles with the cardan shaft turning (max 30°) as this could damage both the cardan shaft and the feet of the pump (FIG. 7).
NEVER USE THE CARDAN TRANSMISSION IF THE FOLLOWING PROTECTIVE COVERS ARE MISSING:
-TRACTOR
-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
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
Don’t perform this operation with the pump running as the depression produced blocks the cover preventing the removal.
