5.1 Precautions for Maintenance and Inspection
When reading this Section, also refer to Section 1.1 in this manual Chapter 1.
 When entering the machine room for maintenance services, ensure that sufficient
ventilation has been started and measure the oxygen concentration so that there is
no risk of oxygen deficiency. The ventilation must be continued steadily until the
work is completed.
 For performing the inspection work, be sure to prepare safety shoes, protective
glasses, gas mask and other proper protective equipment and do not fail to use
them whenever they are required.
 After stopping the machine and before working on a regular inspection or overhaul,
be sure to shut off the main motor power, control power, and other power to each
equipment and valve. After they are shut off, be sure to make the switches
inoperable by others. Also, be sure to attach notification tags to prohibit operation
(lock-out/tag-out).
 When any manual stop valve has been closed, be sure to make the valve
inoperable by others and put a notification tag to prohibit the operation (tag-out).
 When the compressor is to be overhauled, check that the internal pressure of this
product is at the atmospheric pressure before starting the work.
 When using lifting devices, e.g. a crane, etc. and/or lifting tools, ensure that they
can sufficiently withstand the load.
 When lifting a heavy load object, do not allow anyone’s body to put under it.
 The work to turn each power supply ON/OFF or operate a lifting unit must be
exclusively performed by qualified personnel.
 When using electric tools, ensure that they are properly managed in accordance
with each instruction manual. Especially before using and while using, be sure to
follow the care instructions on the safety of each instruction manual.
 Be sure to use only genuine parts for replacement. Using parts that are
not genuine can cause damage to this product or other devices during operation.
 Do not convert or modify this product or its components without prior permission
from MAYEKAWA. Otherwise, it can lead to an unexpected accident.
 Exercise sufficient care for handling a heavy load, and use such a lifting device as a
crane or work with an adequate number of personnel commensurate with the
magnitude of the weight. Also, be sure to use stud bolts (safety retention bolts) and
other support tools for the work. Neglecting the above warning can lead to low back
pain of the worker or injury due to dropping of the parts.
 If two or more people are to work together, be sure to clearly define the work
procedures to
 share a common understanding among all workers before performing the work.
 Not only the work to turn each power supply ON/OFF or operate a lifting device, but
also any type of work requiring qualification must be exclusively performed by
qualified personnel.
