•
In a dusty air be careful that the dust does not blow in the direction of the air aspiration system. The air filter
becomes dirty more quickly and as a result, maintenance, is required more frequently and for the cooler as well..
•
Do not locate the machine anywhere where there is a risk of explosion. Unless the machine has been
technically modified with this in mind. Pay special attention to the indications on electric and diesel motors.
•
Situate the machine in such a way that the workplace is protected from any possible falling objects either on
the machine or on personnel working nearby. Wear a protective hard hat
WARNING!
•
Secure the machine so that it cannot move, with the hand brake on and the blocks for this purpose. It is
advisable to remove the machine lighting system and keep it in a safe place.
•
Activate the machine with the requisite safety devices.
•
Lay the transport pipes using the shortest route possible. Calculate generous radii for changes of direction
(curve radius = six times the external diameter of the pipes), so that the transport hoses do not bend The least number
of couplings used the better, as in this way the material flows more freely from inside the transport pipes.
•
Carefully attach the riser lines with the pipe attachments provided, so that they do not break as a result of
their own weight. We recommend our leather or fabric couplings for the pipes
•
Secure all the joints with the pipe couplings to avoid them opening.
• Check the pipes and couplings regularly for wear (abrasion and ageing, see the safety check list for optimum state).
For safety when operating it is important only to use original
UTIFORM transport
pipes and couplings (or
those authorized by the manufacturer).
6.2
Transport hoses and couplings
There are various types of transport pipes which differ in their interior diameter (also known as nominal
diameter)
The selection of nominal diameter corresponding to each pipe depends on the material transported. The
following points serve as a guide:
Granulation of supplementary material from 4 to 6 mm:
Nominal Diameter 50, 60 o 65
Granulation of supplementary material up to 8 mm, at the most a third of the biggest granules, washed sand, mainly
cement:
Nominal Diameter 60 or 65
Granulation of supplementary material from 8 mm to a maximum of 12 to 16 mm, glutinous sand, mostly grain,
mostly cement
Nominal Diameter 65
All the transport pipes used should be the same nominal diameter, since when using different
nominal diameters, plugs can easily form, and this reduces the transporting efficiency of the machine.
Depending on the nominal diameter the transport pipes, various couplings are required in order to adapt to the
various diameters.
The transport pipes are subject to natural wear, due to abrasion and ageing and therefore a specialist, or other
qualified personnel should check them every 3 months at least to ensure that they are not worn and are in good
condition.
