The CE mark appears on the main nameplate. If the
product is installed as part of a larger machine, this
larger machine is in turn subject to EU directives
and must therefore obtain a general CE mark for the
machine as a whole. The machine must not enter
circulation in the EU until this is done.
Conformity
The declaration of conformity (see section 15.
"Other documentation") attests that the products
comply with all essential health and safety require-
ments set out in Annex I of the Machinery Directive
2006/42/EC.
If our product is used other than as speci-
fied, hazards may occur that could not be
foreseen by the manufacturer. Any result
loss or damage is not the responsibility
of Parker Hannifin.
If the described product is installed in a
machine that came into circulation before
1995, note the following: If the function
has not been changed significantly,
commissioning may not take place until
conformity with national occupational health
and safety provisions has been established
for the machine as a whole, in particular
those provisions implementing the Use of
Work Equipment Directive
If the function has been changed signifi-
cantly, a new conformity procedure must be
carried out in accordance with the Machinery
Directive 2006/42/EC.
