BIFFI F01-2000 ELECTRIC ACTUATOR
INSTRUCTION AND OPERATING MANUAL
4 LUBRICATION
4�1 LUBRICATION INSPECTION
The actuator is lubricated for life, therefore
under normal working conditions it is not
necessary to replace or refill the oil. However
it is recommended to check the oil level every
3-5 years using holes 1 or 2 depending on
mounting position.
The actuator is fitted with oil plugs (parts 1, 2),
so that any assembly on the valve has at least
one oil plug on the upper part of the housing
and one on the lower part.
The actuator is supplied with oil and greased
where necessary.

IMPORTANT
Electric actuator F01-2000 shall be installed and
maintained according to the applicable rules
regarding the electrical installations in hazardous
area (other than mines) classified as zone 21
(dust); example: EN 61241-14 (dust) and/or other
national standards.
Please make sure that:
- The joint surfaces are greased with silicon oil
or equivalent before assembly.
- The cable glands have minimum protection
degree IP68 (EN 60529).
- Periodically verify the quantity of dust
deposited on the enclosure and clean it if
more than 5mm.
• Replace the weatherproof seals that may
have been removed (O-ring for the covers,
O-ring for the explosionproof joint of the
motor).
When the Ex d e version is supplied, according
to the protection degree shown on the
nameplate, waterproof cable glands with a
minimum IP68 protection degree, can be used.
WARNING
Do not operate the actuator electrically when the
electrical enclosures are removed. Operating the
