7. MAINTENANCE
In use, the Solidsvac SV70-SP requires little to no maintenance, however Solidsvac recommends that the following strict measures are
taken to ensure the pump remains in good working order for as long as possible.

SERVICE TIPS
- Clean the machine areas before removing pneumatic components.
Note: When steam cleaning or using water to clean a machine, be sure that ller openings, breather caps etc are protected
from possible entry of water into the system.
- Use clean plastic plugs to cover the ends of disconnected lines or to plug openings when working on a pneumatic system.
- A clean workbench is an absolute ‘MUST’ when servicing components. An industrial-type vacuum cleaner is a valuable aid in
removing dust, dirt and tiny metal particles from the work area.
- Check the condition of your tools – they should be clean. Always use hammers made of plastic or leather, so there is no danger
of metal chips getting into components.
- When removing parts for service, clean them and then store them in plastic bags or other clean containers until they are
installed again.

MAINTENANCE SUGGESTIONS
- Set up a maintenance schedule and follow it diligently.
- Inspectlterelementsthathavebeenremovedfromcompressorsandthesystemforsignsoffailure,whichmayindicatethat
the service interval should be shortened or that there are impending system problems.

- Use common-sense precautions to prevent dirt entering components that have been temporarily removed from the circuit.
