Maintenance and Inspection:
To ensure safe use, be sure to carry out daily inspections. If any
abnormality is found during inspection, replace with a new one.
1. Please confirm that the upper and lower panels and waist rings
are properly placed. In particular, if pressure is applied to the
waist ring in a state of displacement and detachment, the air
spring may rupture.
2. If foreign matter, oil, or chemicals are stained on the air
spring, be sure to remove them.
3. If lubricating oil is mixed into the air spring bladder, please
clean it at any time and clean the rubber bladder with water
regularly.
4. Please confirm that the supply pressure is appropriate. In
particular, abnormal phenomena are prone to occur in the pipes,
which should not be ignored.
5. Please replace the air spring in the following situations. There
are cracks, damages, and wear on the outer rubber layer that go
deep into the cord layer. The air spring is abnormally deformed and
partially bulges. Even if there is no external injury, sometimes
delamination occurs due to the accumulation of air inside the
rubber layer and the frame. Oil, chemicals, heat, etc. can cause
the rubber surface to swell and harden.
6. Corrosion of the upper and lower panels and waist rings will
cause damage to the air spring. When corrosion occurs, parts should
be replaced.
