Safety During Maintenance And Repair - Atlas Copco XAVS 1800 Instruction Manual

20 If the working process produces fumes, dust or
vibration hazards, etc., take the necessary steps to
eliminate the risk of personnel injury.
21 When using compressed air or inert gas to clean
down equipment, do so with caution and use the
appropriate protection, at least safety glasses, for
the operator as well as for any bystander. Do not
apply compressed air or inert gas to your skin or
direct an air or gas stream at people. Never use it
to clean dirt from your clothes.
22 When washing parts in or with a cleaning solvent,
provide the required ventilation and use
appropriate protection such as a breathing filter,
safety glasses, rubber apron and gloves, etc.
23 Safety shoes should be compulsory in any
workshop and if there is a risk, however small, of
falling objects, wearing of a safety helmet should
be included.
24 If there is a risk of inhaling hazardous gases,
fumes or dust, the respiratory organs must be
protected and depending on the nature of the
hazard, so must the eyes and skin.
25 Remember that where there is visible dust, the
finer, invisible particles will almost certainly be
present too; but the fact that no dust can be seen
is not a reliable indication that dangerous,
invisible dust is not present in the air.
26 Never operate the unit at pressures or speeds
below or in excess of its limits as indicated in the
technical specifications.
SAFETY DURING MAINTENANCE AND
REPAIR
Maintenance, overhaul and repair work shall only be
carried out by adequately trained personnel; if
required, under supervision of someone qualified for
the job.
1 Use only the correct tools for maintenance and
repair work, and only tools which are in good
condition.
2 Parts shall only be replaced by genuine Atlas
Copco replacement parts.
3 All maintenance work, other than routine
attention, shall only be undertaken when the unit
is stopped. Steps shall be taken to prevent
inadvertent starting. In addition, a warning sign
bearing a legend such as "work in progress; do
not start" shall be attached to the starting
equipment. On engine-driven units the battery
shall be disconnected and removed or the
terminals covered by insulating caps. On
electrically driven units the main switch shall be
locked in open position and the fuses shall be
taken out. A warning sign bearing a legend such
as "work in progress; do not supply voltage" shall
be attached to the fuse box or main switch.
4 Before dismantling any pressurized component,
the compressor or equipment shall be effectively
isolated from all sources of pressure and the entire
system shall be relieved of pressure. Do not rely
on non-return valves (check valves) to isolate
pressure systems. In addition, a warning sign
bearing a legend such as "work in progress; do
not open" shall be attached to each of the outlet
valves.
5 Prior to stripping an engine or other machine or
undertaking major overhaul on it, prevent all
movable parts from rolling over or moving.

6 Make sure that no tools, loose parts or rags are left
in or on the machine. Never leave rags or loose
clothing near the engine air intake.
7 Never use flammable solvents for cleaning (fire-
risk).
8 Take safety precautions against toxic vapours of
cleaning liquids.
9 Never use machine parts as a climbing aid.
10 Observe scrupulous cleanliness
maintenance and repair. Keep away dirt, cover
the parts and exposed openings with a clean cloth,
paper or tape.
11 Never weld on or perform any operation
involving heat near the fuel or oil systems. Fuel
and oil tanks must be completely purged, e.g. by
steam-cleaning, before carrying
operations. Never weld on, or in any way modify,
pressure vessels. Disconnect the alternator cables
during arc welding on the unit.
12 Support the tow bar and the axle(s) securely if
working underneath the unit or when removing a
wheel. Do not rely on jacks.
13 Do not remove any of, or tamper with, the sound-
damping material. Keep the material free of dirt
and liquids such as fuel, oil and cleansing agents.
If any sound-damping material is damaged,
replace it to prevent the sound pressure level from
increasing.
14 Use only lubricating oils
recommended or approved by Atlas Copco or the
machine manufacturer. Ascertain that the
selected lubricants comply with all applicable
safety regulations, especially with regard to
explosion or fire-risk and the possibility of
decomposition or generation of hazardous gases.
Never mix synthetic with mineral oil.
