FOR OM4A MOTORS
• The interior of this motor uses food-grade, non-toxic mineral oil. Should doubts arise,
please, consult the factory.
• In no case is any other type of oil permitted.
IMPORTANT:
By not observing this warning, Ebara is exempt from any responsibility for
any damage that may occur with the equipment, the health of the client or the
environment.
• It is not necessary to verify the oil level for new motors and/or those repaired in our
factory, however with motors stored for more than a year, verification is necessary.
