Graviner recommend that the Detector Base and sample pipe are blown through with Clean
Air to remove any potential blockages as shown in the image below.
Clean Air at a working pressure of up to 90 PSI should be used.
WARNING - Do NOT remove the Detector Base from the engine crankcase
whilst the engine is in operation.
This action should be carried out whilst the engine is stopped to avoid the
possibility of hot oil coming out of the Detector Base.
Please Note
Graviner Detector Heads should only be cleaned with the recommended cleaning fluid and
cleaning buds.
Many cleaning fluids have been evaluated by Graviner the Electrolube ASC fluid is
recommended by Graviner as our tests have shown it offers the best cleaning ability and
leaves no residue on the glass chamber.
(Note: Do not use any third party electronic contact cleaners, isopropyl alcohols, flux
removers, any harsh chemical cleaners, etc., as these will affect the Detector
performance.
Only use the official Graviner Cleaning products).
