Safety prescriptions for mechanical technician
a) To prevent unbalances that can lead to serious damages, the user must follow the
assembly with the most care and avoid shocks and stresses on the separator parts.
b) After every maintenance intervention or regulation be sure that tools or other extraneous
bodies are not present in the machine moving parts, to avoid damages to the machine
and/or troubles to the personnel.
c) Do not allow to unauthorized personnel to work on the machine.
d) Never insert the body, limbs or fingers in the articulated or sharp opening of machine parts
without shields.
e) Do not use gasoline or inflammable solvents like detergent, but always use authorized, not

-
nylon gasket in the bowl hood,
-
bowl wall portions near the product discharge holes in the bowl body.
Consult SEITAL SERVICE if one or more of the following observations are made after a
deep check:
max. 1 mm.
- the largest depth of the trace exceeds 1
mm,
- the bottom radius of the erosion trace is
less than 1 mm in the narrowest point, or
coarse scratches are present,
- defects presumably caused by corrosion
are present.
Radius < 1 mm.

Safety prescriptions for the electrician
a) Check efficiency of earthing connections and be sure they are realized in accordance with
local regulations.
b) Before every intervention on electrical components, verify the supply mains are
disconnected.
c) After every intervention on electric panel, close and block it with the door lock of the
main switch, before connecting the mains supply and start the machine.
d) In case of accident due to electric current immediately cut the supply to electric mains then
disjoin the injured (usually he lose consciousness) from the parts under voltage. If this
needs an excessive time, drive away the injured using insulating material as a wood or pvc
stick, cloth, leather.
ATTENTION
