Replacing the Oil Filter
If the system has been just operated, shut off the engine and wait at
least 30 seconds for the air pressure to vent before working on the
system.
Do not attempt to change the oil filter until the oil has
cooled. Hot oil can cause severe burns.
1. Clean the area around the tank and the filter to prevent
contamination.
2. Remove the drain plug and drain the oil into a container large
enough to hold at least 1.32 USG (5 liters) for the VR70 and 2.38
USG (9 liters) for the VR150.
3. Install and tighten the plug.
4. Remove the filter by turning it counterclockwise. Before
discarding the filter, check to make sure that the threaded nipple
did not unscrew with the filter. If the nipple is in the filter, remove
it carefully to avoid thread damage and replace it in the tank
housing.
Do not fully thread the nipple into the tank as this could
inhibit the oil cross drilling causing system failure and
potential compressor damage.
5. Check the gasket-sealing surface on the front of the tank for
contamination, old gasket material or damage.
6. Apply a thin coating of compressor oil to the filter-sealing gasket
and fill the filter with VMAC compressor oil.
7. Spin the filter onto the threaded nipple until the gasket contacts
the sealing surface on the tank, then tighten the filter an
additional 3/4 to 1 turn to seat the sealing gasket.
Never over-tighten the filter, as this may damage the
seal or the filter.
8. Remove the filler plug from the air inlet control valve and pour
VMAC compressor oil into the oil filler hole on the inlet control
valve using a funnel.
