• All guards are in place and securely fastened
• All hoses and/or pipes inside the machine are in good condition, secure and not rubbing
• No leaks occur
• All fasteners are tight
• All electrical leads are secure and in good order
• Safety valves and other pressure relief devices are not obstructed by dirt or paint
• Air outlet valve and air net, i.e. pipes, couplings, manifolds, valves, hoses, etc. are in
good repair, free of wear or abuse
• All pre-filters are not clogged
• If warm cooling air from compressors is used in air heating systems, e.g. to warm up a
workroom, take precautions against air pollution and possible contamination of the breathing
air.
• On water-cooled compressors using open circuit cooling towers, protective measures must be
taken to avoid the growth of harmful bacteria such as Legionella pneumophila bacteria.
• It is not allowed to directly use the hot water of the cooling water circuit of the compressor as
process water in pollution sensitive applications such as the food -and pharmaceutical industry.
• Do not remove any of, or tamper with, the sound-damping material.
• Never remove or tamper with the safety devices, guards or insulations fitted on the machine.
Every pressure vessel or auxiliary installed outside the machine to contain air above
atmospheric pressure shall be protected by a pressure relieving device or devices as required.
• Yearly inspect the air receiver. Minimum wall thickness as specified in the instruction book must
be respected. Local regulations remain applicable if they are more strict.
Note: Also consult the following safety precautions: Safety precautions during operation and
Safety precautions during maintenance or repair.
These precautions apply to machinery processing or consuming air or inert gas. Processing
of any other gas requires additional safety precautions typical to the application which are not
included herein.
Some precautions are general and cover several machine types and equipment; hence some
statements may not apply to your machine.
1.5 Safety precautions during maintenance or repair
Warning: All responsibility for any damage or injury resulting from neglecting these
precautions, or non-observance of the normal caution and care required for installation,
operation, maintenance and repair, even if not expressly stated, will be disclaimed by the
manufacturer.
• Always use the correct safety equipment (such as safety glasses, gloves, safety shoes, etc.).
• Use only the correct tools for maintenance and repair work.
• Use only genuine spare parts for maintenance or repair. The manufacturer will disclaim all
damage or injuries caused by the use of non-genuine spare parts.
• All maintenance work shall only be undertaken when the machine has cooled down.
• A warning sign bearing a legend such as "Work in progress; do not start" shall be attached to
the starting equipment.
• Persons switching on remotely controlled machines shall take adequate precautions to ensure
that there is no one checking or working on the machine. To this end, a suitable notice shall be
affixed to the remote start equipment.
