Instructions Concerning Particular Hazards - Bottarini GDP21 Maintenance And Operating Manual

3. Security Regulations
Never use solvents with dangerous
properties for cleaning parts.
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.
Wear suitable eye protection when
inspecting the system. Make sure that the
openings of spray containers, valves,
pipes, or atomizers are never directed at
yourself or at any other person during the
inspection.
The fuel used in these systems is highly
inflammable, toxic and poisonous. Avoid
contact with eyes and skin, and never
inhale vapors. Should you accidentally
swallow fuel, do not induce vomiting, but
seek medical attention.
Should fuel come into contact with the
eyes, or in case of eye irritation by vapors,
flush eyes with plenty of clean water and
seek medical attention.
Every time a message is displayed or
there is a suspicion that an internal part
of the machine has overheated, the
machine must be shut down. Never open
the inspection cover, however, before the
machine has cooled down sufficiently to
rule out the possibility of the oil vapors
igniting spontaneously when mixed with
air.
In order to avoid an increase in
operating temperature, inspect and clean
the heat transfer surfaces (cooling ribs
etc.) regularly. Draw up a schedule for the
most suitable cleaning intervals for each
machine.
Avoid damaging the safety valves and
other pressure-reducing devices. In
particular, make sure that they are not
blocked through paint, oil carbon, or
dust accumulation, which could impair
the effect of these devices.
The insulation or protective shielding of
parts whose temperature may exceed
80 °C and which may accidentally be
touched by personnel may not be re-
moved before these parts have cooled
down to room temperature.
Check the accuracy of the pressure
and temperature displays regularly. If the
permissible tolerance limits have been
exceeded, then they must be replaced.
Never carry out welding work or any
other work that produces heat in the
vicinity of fuel or oil systems. Systems,
which could contain fuel or oil, have to be
completely drained and cleaned, e.g. by
means of a steam jet, before proceeding
with the work to be carried out.
Never carry out any welding work on any
pressure tank or components under
pressure, or modify them in any way.
12
If work causing heat, flames, or sparks
has to be carried out on a machine, the
surrounding components must be
protected with nonflammable material.
Before dismantling or overhauling a
compressor, engine, or any other
machine, make sure that no movable
part with a weight of more than 15 kg
can move or roll away.
Machines whose main movement is
back and forth must be moved at least
once, rotating machines several times,
in order to make sure that there is no
mechanical malfunction in the machine
or in the driving part.
Only experienced persons may be
charged with slinging loads and instructing
crane drivers. These instructors must
remain within sight of the operator or be in
touch with him via walkie-talkie or similar
device.
During assembly work above body
height, use appropriate or otherwise safety-
relevant climbing aids and working
platforms. Do not use machine parts as
climbing aids! Wear safety belts when
carrying out maintenance work at greater
heights.
Keep all steps, handles, railings,
platforms, scaffolds, and ladders free of
dirt, snow, and ice.
Before beginning maintenance and
repair, clean the machine, particularly
couplings and bolted connections, of oil,
fuel, and special care products. Do not
use aggressive detergents. Use lint free
cloths for cleaning.
After cleaning, remove all covers and
seals.
After cleaning, check all fuel, engine oil,
and hydraulic fluid lines for leaks, loose
connections, chafing and damage. Correct
any faults immediately.
Always tighten bolted connections
loosened during maintenance and repair
work.
If it is necessary to dismantle safety
devices during machine set-up, mainte-
nance, and repair work, the safety devices
must be reassembled and checked imme-
diately after completing the maintenance
and repair work.
Ensure safe, environment-friendly
disposal of process materials as well as
replaced parts. Oil containing
components, such as fine separators and
oils, must be disposed of in accordance
with the relevant legal provisions. Oil must
not enter the soil!
Safety precautions for work with
batteries
The fluid contained in batteries is diluted
sulfuric acid which can cause blindness if
brought into contact with the eyes, or
serious burns if brought into contact with
the skin. For this reason it is essential to
work with the greatest of care when
servicing batteries, e.g. when checking
battery charge, and to take all necessary
safety precautions.
Always wear long-sleeved overalls, acid-
resistant gloves and safety goggles.
On charging a battery, an explosive gas
mixture is formed in the cells, which can
escape through the vent holes in the
sealing caps. If ventilation is poor, a highly
explosive atmosphere can form around
the battery, and can persist for several
hours after charging.
Thus:
* Never smoke in the vicinity of batteries
that are being charged or have just
been charged.
* Put up prohibition signs for fire, open
flames and smoking in workshops
where batteries are charged.
* Never interrupt a current-carrying
circuit at battery terminals because
of the danger of spark formation.
* Proceed particularly cautiously when
connecting or disconnecting rein-
forcement cables or quick-charge cable
clamps.
When starting up using jumper cables
or auxiliary batteries, first connect the
positive terminals and then the negative
terminals. After starting the engine, first
disconnect the negative terminal (ground
cable) and only then the positive terminal.
Disconnect the auxiliary battery after the
starting procedure in order to avoid the
risk of the release of gas (explosion
hazard).
3.7 Instructions concerning
particular hazards
Electrical Energy
Only use original fuses with the
specified amperage.
In case of faults in the electrical
power supply, shut down the machine /
installation immediately!
Work on electrical systems or equipment
may only be carried out by a trained
electrician or by trained persons under
the leadership and supervision of a trained
electrician in accordance with the
standards of electrical engineering.
