200 1.1 Refuelling Valve Service Instructions  
RFC-88-K-SL and RFC-88-K-FL  
We recommend that the coupling O-rings are coated with Molykote 1292”  
grease after every event. Please use the RFC-88-K service tool as described in the  
following procedure. The seals, the lubricant and an O-ring mounting tool are  
available as kit (part number RFC-88-K service kit) from Krontec. The O-rings  
supplied with the kit should be replaced after half a season or 5,000 km. In  
addition, we recommend that the coupling should be completely rebuilt after a  
complete season or 10,000 km by Krontec (replace all seals, etc.).  
We also recommend that the coupling locking mechanism is lubricated regularly  
with silicon spray.
