NOTICE

Keep all partsclean from contaminants.

Contaminants may cause rapid wear and shortenedcomponent life.

Note: Put identification marks on all hoses, on all hose assembliesand on all tube assembliesfor installation purposes. Plug all hose assembliesand tube assemblies. Plugging all hose assemblies and tube assemblieshelps to prevent fluid lossand also helpsto keep contaminants from entering the system.

Do not disconnect the air lines until the air pressure in the system is at zero. If hose is disconnected under pressure itcancause personal injury.

1. Release the pressure from the air system. Refer to the Original Equipment Manufactures (OEM) for the correct procedure.
