of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.

Dispose of all fluids according to local regulationsand mandates.

NOTICE

Keep all parts clean from contaminants.

Contaminants may cause rapid wear and shortened component life.

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

Do not disconnect the air linesuntil the air pressure in the system is at zero. If hose is disconnected under pressure it can cause personal injury.

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

2. If the engine is equipped with a hydraulic pump on the rear of the air compressor, remove the hydraulic pump. Refer to the OEMfor the correct procedure.
