3.4 MAINTENANCE
In no case should the operator use combustible or flammable liquids or detergents for
cleaning the machine.
Always wait a few minutes after switching the machine off so that the machine system
has time to re-establish non-operational conditions (temperature and pressure).
!
During maintenance work do not contaminate the environment with eventual residual
waste products and always follow the prescribed directives in force regarding disposal.
NEVER disassemble the cylinder.
Do not carry out repairs or maintenance work while the machine is operating or is
connected up to the electricity supply.
Only carry out the maintenance operations and repairs indicated in the relevant sections
of this guide. We stress that work carried out on the machine by unqualified staff can
compromise the overall safety level of the machine and expose the operator to serious
safety hazards.
3.5 ELECTRICITY SUPPLY
In the case that extension cords are used, check that the cord core section is in
proportion to the length of the cord and that the position of the cord is not subject to
damage of any kind (avoid areas where the cord could be walked on or wet surfaces).
Check that the connection to the mains supply is equipped with safety devices as
prescribed by the directives in force governing the subject (grounding system and
differential circuit-breaker).
