CB65 backhoe control valves and leaver lubrication?

[zski128]

I noticed my controls on my backhoe area bit sticky. In the owners manual it states to lubricate them but no other details. Where exactly should I grease them? Not seeing anything obvious other than removing the small rubber boots around them. Use just basic chassis grease or some WD-40? What does everyone else do?

If it was my backhoe I would lift the boots and spray chain lube in there.
