Air Clutch Lubrication
Clutches
are self-lubricating and require little maintenance. Lubricate the air cylinders as required every 75–100 hours of operation and at the end of the season to keep the pistons lubricated.

dry
silicone
included
in the kit—using penetrating oil, grease, brake cleaner, and so on, voids the warranty and reduces clutch performance.
Any
solvents used will
only work temporarily
and then dry out the clutch. Heavier oils may gum up
clutches.
