Symbols And Definitions - Bottarini GDP21 Maintenance And Operating Manual

3. Security Regulations
Machine and system parts where
service, maintenance, and repair work is
being carried out must be switched off
load, if required by regulations. First check
the deenergized parts to make sure they
are off load, then connect to ground and
short-circuit, and insulate neighbouring
parts that are under tension.
The electrical equipment of a machine /
installation must be inspected / tested
regularly. Faults, such as loose con-
nections or overheated cables, must be
corrected immediately.
If work has to be carried out on live
parts, then call in a second person to
operate the emergency stop switch or
master switch with over voltage release.
Cordon off the working area with a red-
and-white safety chain and a warning
sign.
Only use insulated tools.
Keep an adequate distance between
the machine/unit and overhead power
lines! When working near overhead power
lines, equipment must not come near the
power lines! Danger! Find out about the
safe distance to be observed!
After touching high-voltage lines:
*
Do not leave the machine.
*
Move the machine away from the
danger area.
*
Warn outsiders not to come closer or
touch the machine.
* Make sure that the voltage is switched
off.
* Do not leave the machine until the line
which has been touched or damaged,
has been switched off load!
When working with high-voltage
assemblies, ground the supply cable
after voltage has been isolated, and
short-circuit the components, e.g.
capacitors, with a ground rod!
Gas, dust, steam, smoke
Only carry out welding, burning, and
grinding work on the machine / installation
when this has been explicitly permitted,
as there may be for example risk of fire
and/or explosion.
Prior to welding, burning and grinding
remove any dirt and inflammable sub-
stances from the machine/system and its
environment and ensure proper ventilation
(danger of explosion)!
Only operate combustion engines in
properly ventilated rooms. Ensure ventila-
tion is adequate before starting up in
closed rooms.
Always adhere to the legal provisions
applicable to the particular location!
Follow the local regulations applicable
at the respective site of installation.
Hydraulic and pneumatic systems
Work on hydraulic equipment may
only be carried out by persons with
special knowledge of and experience
in hydraulics.
Check all lines, hoses, and bolted
connections regularly for leaks and visible
damage. Repair any damage immediately.
It is essential that damaged parts should
be replaced! Spurting fluid can lead to
injuries and fires.
Before beginning repair work, relieve
the pressure in system sections to be
opened and in pressure lines (hydraulic
and compressed-air lines) in accordance
with the descriptions of the
subassemblies.
Hydraulic and compressed-air lines
must be routed and fitted in accordance
with the regulations. Do not confuse the
connections!
The fittings, length, and quality of
hoses must be in accordance with the
requirements.
Noise
Protect personnel at risk from noise, in
accordance with EU Directive 2003/10/EU.
Oils, Greases and Other Chemical
Substances
When handling oils, greases and other
chemical substances, observe the safety
regulations applicable for the product.
Caution when handling process
materials (risk of burning / scalding).
Potentially-explosive environments
The operation of the compressor in
areas where there is a risk of explosion is
strictly forbidden! (Exception: specially-
made compressors with the necessary
technical modifications for use in such
areas)
Note
GARDNER DENVER accepts no
responsibility for any damage or injury
caused by noncompliance with these
safety measures or noncompliance with
normal care and caution during the
handling, operation, maintenance or repair
of this compressor, even if not expressly
stated in this operating manual.
