The compressor system is under sufficient pressure that a leak could force the air/oil mixture through the skin directly into your bloodstream. This will cause death. Never adjust or attempt to make any repairs to the compressor system while engine is running. Components and hoses under pressure could separate suddenly and fly out and cause serious injury or death.
1.4 Warranty VMAC Standard Warranty (Limited) For complete warranty information, including both our VMAC Standard Warranty (Limited) and VMAC Lifetime Warranty (Limited) requirements, please refer to our current published warranty located at: www.vmacair.com/warranty If you do not have access to a computer, please contact us and we will be happy to send you our warranty.
1.5 System The compressor system is protected from over pressurization by a mechanical inlet control in the compressor that regulates airflow in response to the demand. There is also a 200 PSI (1,379 kPa) pressure relief valve in the air/oil separation tank to protect the system from over pressurization.
1.6 Auxiliary Air Tank If an auxiliary air tank is to be used with this system the following setup MUST be followed. Failure to observe this procedure will result in damage to the system. 1. The auxiliary air tank must be connected to the supply valve. 2.
2.0 Routine Maintenance Impact damage and premature bearing failure may occur in the compressor bearings if the system is not operated on a regular basis due to vibration caused by engine operation. Operate the system at least every 30 days for 15 minutes at no load to ensure bearing lubrication and rotation.
2.1 Maintenance Schedule The following maintenance schedule should be adhered to, to assure good performance and long service life. The hours indicated are those displayed on the compressor hour meter. Service should be performed at the lesser of the two intervals, whichever occurs first. Check the Illustrated Parts List for replacement part numbers or call VMAC.
2.2 Start-up Procedure Read all the service procedures and safety warnings before operating the compressor. The unit must be level or must not exceed 35°, as higher angles will affect lubrication and oil and air separation. 2.2.1 Make sure the air operated equipment is securely connected to the pressure supply valve and turned OFF.
2.3 Shutdown Procedure 2.3.1 Turn OFF the air equipment connected to the supply valve. 2.3.2 Close the supply valve. 2.3.3 Turn the compressor ON-OFF switch to the OFF position. 2.3.4 Allow the engine to return to the low idle state. 2.3.5 Shutdown the engine according to the instructions in the Lincoln Welder’s Owners Manual.

The compressor system is a closed loop. After draining oil, there will be some residual oil remaining in various components of this system. Use caution when re-filling the system with oil to ensure that the oil level does not exceed the high mark indicated on the dipstick. Overfilling could lead to oil in the discharge air.
2.4.6 Inspect the O-ring on the dipstick for abrasions or nicks. Replace the O-ring if damaged. Install the oil level dipstick and tighten it securely. 2.4.7 Start the engine following the start-up procedure number 2.2. 2.4.8 Turn the compressor switch on the control panel to the ON position.
2.7.3 Examine the hoses and air lines for cuts or cracks. 2.7.4 If any of the air lines or hoses show damage they should be replaced by an authorized VMAC or Lincoln Electric Service Centre before operating the equipment. VMAC – Vehicle Mounted Air Compressors...
2.8 Change compressor oil Follow all safety precautions. 2.8.1 Clean debris and dust from the area around the drain valve of the oil/air separator tank to prevent contamination. 2.8.2 Insert a hose over the air/oil separator tank’s drain valve outlet and open the valve to drain the oil into a container large enough to hold at least 1-1/2 US Gallons (6 liters).
Dispose of the oil in accordance with the Environmental Protection Laws in your location. 2.8.4 Remove and replace the oil filter at this time following procedure number 2.9. 2.8.5 Clean debris and dust from the area around the oil level dipstick of the air/oil separator tank to prevent contamination.

2.9.1 Clean debris and dust from the area around the manifold block and the filter to prevent contamination. 2.9.2 Remove the filter by turning it counterclockwise using a suitable filter wrench. Check the filter to make sure that the threaded nipple did not unscrew with the filter.
Air filter assembly and air filter element are supplied by Lincoln Electric Company. Please your contact a Lincoln Electric service representative for replaceable components 2.10.1 Clean loose dust and debris from the area around the filter cover to prevent contaminants from entering the system.
2.11 Change coalescing filter Follow all safety precautions. Do not use a screwdriver punched into the side of the filter, as this practice can damage the scavenging tube and screen. VMAC – Vehicle Mounted Air Compressors Toll Free: 1-888-241-2289 Local: 250-740-3200 Fax: 1-250-740-3201...

Check the filter to make sure that the threaded nipple did not unscrew with the filter. If it is in the filter, remove it carefully to avoid thread damage, clean the threads and then coat the threads that go into manifold block with a small amount of Loctite blue and install it into the manifold block.
2.12 Electrical The air compressor electrical system receives power from the main engine RUN-STOP switch, on the control panel, when the switch is in the RUN position. The compressor switch is turned to ON to start the compressor producing high pressure air. If the compressor’s oil temperature goes above 290°F (143°C) the thermal switch located in the primary air oil separator will disengage the compressor clutch and illuminate the ‘Compressor Protection’...
Electrical testing should be performed according to the processes described in the troubleshooting charts and in conjunction with the manuals provided by Lincoln Electric. VMAC – Vehicle Mounted Air Compressors Toll Free: 1-888-241-2289 Local: 250-740-3200...
