NO FUNCTIONAL LOCK-OUT
It is possible after the bike being hung up or laid sideways, the air inside the Damper
Cartridge gets to the wrong chamber, causing lock-out to temperately malfunction.
Generally the damper will self-adjust after a short ride. For quick on-site remedy, proceed
following procedures.
Setting:
Air pressure: Release air from the air spring chamber.
Compression: on the open mode.
Rebound index: Fastest position (turn rebound damper knob completely counterclockwise)
Solution:
Slowly compress fork to full travel and then let fork travel restore to original position 3 to 5
times.
Test lock-out function, Reset air pressure.
