Pneumatic system safety instructions
1. Release the pressure in all lines carrying compressed
air prior to any maintenance and repair work.
» Lower all pneumatically controlled components to the
ground.
» Move all control levers of the pneumatic control
valves several times.
2. Compressed air with dirt escaping under high
pressure can lead to eye and skin injuries. Always
consult a doctor immediately even if the wound
seems insignificant – otherwise serious infections or
irreparably damages could set in!
3. Replace the hose or line if one of the problems
mentioned below is detected.
» Damaged or leaky pneumatic seals.
» Worn or torn shells or uncovered reinforcement
branches.
» Expanded shells in several positions.
» Foreign bodies jammed or stuck in protective layers.
4. Retighten leaking screwed fittings and hose
connections only when the system is not under
pressure; i.e. release the pressure before working on
pressurized lines!
5. Never weld, or solder damaged, or leaking pressure
lines and screw connections. Replace damaged parts
with new ones!
6. Never search for leaks with your bare hands, always
wear protective gloves!
» Use paper or wood to check for minor leaks.
7. Repair or replace leaks and damaged pressure lines
immediately.
2.5.2
Incorrect Handling of
Pneumatic Equipment
WARNING
Defective pneumatic lines pose an
injury hazard!
» Route pneumatic lines safely and
check regularly for damage.
» Provide lines with chafe protection.
» Replace defective lines immediately.
WARNING
Separated pneumatic lines pose an
injury hazard!
Compressed air can escape under high
pressure.
» Always relieve pressure in
pneumatic equipment before
working on machine.
» Check pneumatic connections
regularly to ensure that they are
properly fastened.
WARNING
Lubricants can pose a health
hazard!
Lubricants can lead to skin and eye
injury and poisoning symptoms upon
contact.
» Avoid direct contact with
lubricants.
Weak pneumatic lines due to incorrect routing or damages
can burst under load. The compressed air then escapes
under pressure resulting in a powerful jet, which can lead
to skin or eye injury.
For this reason always
- Lay pneumatic lines so that they are not kinked or
pinched.
- Check regularly for damage and replace as required.
Always wear your personal protective equipment.
