Regular Inspection Instructions

Read the "Maintenance and Repair Safety" section prior to
performing any work on the system (beginning on page 23).
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.
Do not overfill the system. Overfilling the system with oil can flood
the sight glass window and make the system appear empty.
Inspecting and Adding Compressor Oil
☐
Ensure the vehicle is parked on level ground and that the compressor system is
depressurized and cool to the touch.
☐
Check the oil level in the sight glass and ensure that it is between the "MAX"
arrow and the "ADD" arrow.
If the level is below the "ADD" mark, perform the following steps:
☐
Remove the fill cap on the tank (above the sight glass).
☐
Using a funnel, pour oil into the fill fitting until the oil level in the sight glass
reaches the "MAX" arrow.
☐
Replace the fill cap and tighten securely.
