 FID jet
The following describes inspection/maintenance for the FID jet.
 Purpose of inspection
• Check if jet is not clogged.
If the jet tip is clogged, it may cause ignition
malfunction, or you may not even obtain peaks.
Clean it by inserting a thin, long stick.
• Check whether jet is dirty
If jet is dirty, it can cause significant noise.
Clean the jet with a cotton swab soaked in organic
solvent (e.g. acetone).
• Check whether the jet is damaged
If the jet is damaged, it may cause abnormal peak
shape.
In that case, replace the jet.
 Removing FID parts
Using the following procedures, remove the FID parts until you can access the part to be inspected.
 Removing igniter and FID collector
1
Remove 2 screws using Phillips screwdriver.
If using the dual FID, the screw position varies
depending on FIDs.
When installing, be careful not to place the screws in
the wrong holes.
