SAS 1SF - Twin Screw Feeder Assy & Control - APRIL 2020 

INSTALLATION 

 

During the installation there are combined actions of several operators, thus is 
necessary work with great caution.  
 
Verify the integrity of the machine, particularly of the fan covers over the electric motors 
that can be damaged during transport.  
 
If the fan covers are dented blocking the fan rotation, restore or replace them before 
commissioning the machine.  
 
When the screw feeder is provided without vertical unload and endless screw, with 
length of the screw exceeding the one of the exhaust pipe because of a customer 
request for installation needs, the customer is in charge of performing a risk analysis 
and of mounting proper protections and/or repairs.  
 
The operations performing the installation must have a technical grounding and proper 
knowledge to operate with adequate expertise.  
 
The user must have an installation area that satisfies the current regulations on health 
and safety on production environments.  
 
Set up an area where install the machine verifying that the floor is flattened and without 
obstacles.  
 
Make room around the machine sufficiently to permit safety and ergonomics to the 
operators and to the fitters. Safety distances from other machines or production areas 
must be observed according to the current regulations.  
 
The installation and working area must be correctly lit up, defined and signalled. It must 
respect the law parameters concerning working areas.  
 
The working area must be forbidden to personnel not involved in the machine 
operation. If this is not possible, barriers or similar means not hindering the production 
must be installed  
 

 

WARNING

The set-up of the machine is usually performed by the manufacturer 

who knows the right methods to do it. In case that the set up cannot be 
performed by the manufacturer, the customer has to ask the manufacturer all the 
information in order to perform it correctly by himself.
