9.3 GENERAL OPERATION AND MAINTENANCE

The following defined maintenance and service intervals for the individual parts of the unit
must be followed to preserve the warranty provided by the manufacturer, MANDÍK, a.s., and
to ensure flawless and safe operation of the unit.
These intervals are specified for standard units in normal operating conditions. For units
operated differently (24/7 operation, higher working temperatures, high dust operations, etc.),
these maintenance and service intervals must be shortened by a minimum of one level below.
Everything is dependent upon the operating conditions based on which the intervals are
defined during commissioning, training and handover of the unit.
Any performed service work, maintenance and technical audits must be recorded in the
operating log book for the unit. The person who places the unit into service is responsible for
creating and maintaining the operating log book. The operator of the unit then records the
individual events.
SAFETY DURING MAINTENANCE:
• ATTENTION: ANY WORK, MAINTENANCE AND INTERFERENCE INTO THE EQUIPMENT
MAY ONLY BE PERFORMED BY PERSONNEL QUALIFIED WITH APPLICABLE
AUTHORISATIONS (E.G. GAS INSTALLATIONS, ELECTRICAL INSTALLATIONS, ETC.)!
• ATTENTION: SERVICE WORK AND MAINTENANCE ON THE EQUIPMENT MAY ONLY BE
PERFORMED WITH THE EQUIPMENT SWITCHED OFF (IT MUST BE LOCKED OUT TO
PREVENT ACCIDENTAL START-UP OR START-UP BY ANOTHER PERSON)!
ATTENTION: ALL ROTATING PARTS (FANS, ETC.) MUST HAVE STOPPED MOVING BEFORE
ENTERING INTO THE EQUIPMENT!
