Special Jobs / Maintenance - Bottarini GDP21 Maintenance And Operating Manual

3. Security Regulations
Check the machine / installation for
external damage and faults at least once
per shift. Any changes noticed (including
changes in operating performance) must
be reported immediately to the authority or
person in charge. If necessary, shut down
and secure the machine immediately.
In case of malfunction, shut down and
secure the machine / installation
immediately. Have malfunctions corrected
immediately.
Observe the operating manual for start-
up and shutdown procedures as well as
inspection displays.

3.6 Special jobs / Maintenance

Care
Observe the setting, maintenance, and
inspection work and intervals stipulated
in the operating manual, including
information about the replacement of
parts / partial sections. This work may
only be carried out by specialists.
Maintenance work, tests and repairs
should be carried out in a well ventilated
room, away from heat, open flames, or
sparks. Appropriate prohibition signs (fire,
open flames, no smoking) must be put up.
Loss of oil leads to a very slippery floor.
Statistics have shown that many accidents
can be attributed to the installation or
maintenance of machines on oily floors or
machine components. For this reason,
always start maintenance work by
cleaning the floor and the machine
exterior.
Inform operating personnel before
beginning to carry out special work or
maintenance. Nominate a supervisor.
After completing repair work, always
check to see whether any tools, loose
parts or cloths have been left in or on
the machine, driving engine or driving
equipment.
Maintenance and repair work is only to
be carried out under the supervision of or
by a person qualified for this
For all work concerning the operation,
production adjustment, conversion, or
settings of the machine / installation and
its safety-relevant equipment, as well as
servicing, maintenance, and repair,
observe the operating manual for startup
and shutdown procedures and the
instructions for maintenance work.
All maintenance and repair work may
only be carried out when the system is
shut down, or, with electrical systems,
when the mains power supply is switched
off. Make sure that the equipment cannot
be switched on by accident.
Whenever the machine/system is com-
pletely powered down for maintenance
and repair procedures, it has to be
secured against unintentional power-on
or the mains supply has to be cut off
with electrical systems.
* Switch off battery master switch and/or
detach connector.
*
Put up a warning sign on the main
switch "Attention! Maintenance work."
Close off the complete maintenance
area, if required.
*
Disconnect the starter battery.
Individual parts and larger subassem-
blies must be carefully attached to the
hoisting gear and secured in case of
replacement.
Only use suitable, technically perfect
hoisting gear and load suspension devices
with adequate carrying capacity. Keep
clear of suspended loads.
Before removing any part under
pressure, separate the aggregate
effectively from all sources of pressure
and release the pressure from the
complete system.
Never use inflammable solvents or
carbon tetrachloride to clean parts.
Take precautions to avoid toxic vapors
from cleaning fluids.
Absolute cleanliness is essential during
maintenance and when carrying out
repairs.
Only carry out maintenance and repair
work when the machine is located on an
even, stable base and is secured against
running away and against buckling.
Only carry out inspection, maintenance,
and repair work when the screw com-
pressor system is at a standstill and is not
under pressure.
Protective devices, i. e. protective grids,
may not be removed during operation.
Caution while the screw compressor is
in operation.
work. After the work has been completed,
replace any protective devices that have
been removed. Operation without
protective devices is not permissible.
Working clothing should be close-fitting
during work on running screw compressor
systems.
Maintenance
During maintenance and repair work, the
contractor has to inform the personnel
about the dangers that can occur during
their work and about measures to avert
such dangers.
The personnel have to support all
measures to improve safety at work.
Safety devices for preventing or
eliminating dangers must be serviced
regularly and their functioning tested at
least once per year. Faults discovered
must be corrected at once or reported
to the supervisor.
Only use the correct tools for
maintenance and repair work.
Only use original spare parts.
All maintenance and repair work may
only be carried out when the system is
shut down, or, with electrical systems,
when the mains power supply is switched
off. Make sure that the aggregate cannot
be switched on by accident.
Whenever the machine/system is com-
pletely powered down for maintenance
and repair procedures, it has to be
secured against unintentional power-on
or the mains supply has to be cut off
with electrical systems.
* Switch off battery master switch and/or
detach connector.
* Put up a warning sign on the main
switch "Attention! Maintenance work."
Close off the complete maintenance
area, if required.
*
Disconnect the starter battery.
Before removing or opening any part
under pressure, separate the equipment
effectively from all sources of pressure
and release the pressure from the
complete system.
For moveable machines support the
towing mechanism and axle with
appropriate means if work is to be carried
out underneath the units (a jack is not
sufficient).
Observe the safety precautions for work
on batteries.
Pay attention to cleanliness. Prevent
dirt from entering by sealing the parts and
exposed openings with a clean cloth, paper,
or tape.
Before the aggregate is approved for
operation after maintenance or an
overhaul, make sure that operating
pressures, temperatures, and time
settings are correct and that the control
and shutdown devices are working
properly.
The electric motor, generator, air filter,
electrical components and control
equipment are to be protected against
the penetration of dampness - for
example when cleaning with a steam
jet - by covering or sealing them.
Under no circumstances should the
sound-insulating material be removed or
modified.
