Hydraulic Driven Air Compressor system to operate erratically. Prior to installing the system, consider the following factors: • For proper operation, VMAC’s Hydraulic Driven Air Compressor Systems require proper hydraulic pressure and flow, ensure the hydraulic circuit is designed with these requirements in mind (see page 17).
Ensure adequate ventilation is provided for cooling and to evacuate the heat generated by the unit. If mounting in an enclosure, VMAC strongly recommends mounting the unit on a pullout drawer and extending the drawer any time the unit is run.
During this time, the Display Box can only be used to view messages as the “ON” and “OFF” buttons are disabled. VMAC - Vehicle Mounted Air Compressors VMAC Technical Support: 888-241-2289 VMAC Knowledge Base: www.kb.vmacair.com...
VMAC’s Hydraulic Driven Air Compressors are not compatible with “load sensing” variable displacement hydraulic pumps. VMAC is unable to provide hydraulic circuit designs or consult on specific hydraulic installations. We recommend working with a local hydraulic expert to design and/or install the hydraulic circuit that will power the Hydraulic Driven Air Compressor system.

General Maintenance Information Routine Maintenance In order to maintain the VMAC warranty, VMAC’s maintenance schedule must be followed. Only genuine VMAC parts can be used to maintain the system. With proper maintenance, the likelihood of premature failure or component replacement can be drastically reduced.
Page 57
Installation Manuals and Illustrated Parts Lists (IPL) The installation manual and illustrated parts list are an invaluable resource when inspecting, diagnosing or repairing the system. The installation manuals and IPL’s are available free of charge from VMAC. VMAC Installation Manuals https://www.vmacair.com/support/manuals/ VMAC IPL’s...
Use only genuine VMAC parts to maintain the system. Genuine VMAC parts are designed to work with the high pressure and heat generated by the compressor. Substituting genuine VMAC parts may void the warranty and could cause equipment damage, injury, or death.
Page 59
The following maintenance schedule must be observed to maintain both the “Standard” and “Lifetime” VMAC warranties and to assure proper performance and long service life of the system. In the event of a warranty claim, VMAC may request service records.
Wear appropriate Personal Protective Equipment and follow all industry standard safety practices. The VMAC supplied and approved compressor oil must be used in this system. Failure to use this special oil will result in damage to the compressor and will void warranty.
