Inspect the Pressure Relief Valve
Inspect the pressure relief valve for signs of corrosion or loss of
functionality. To test the pressure relief valve functionality, turn the
system on and bring it up to operating pressure. Pull the ring on the
pressure relief valve to depressurize the system. Turn the system
off, and ensure the system comes back to operating pressure when
the system is restarted. If the pressure relief valve is showing loss of
functionality, contact your local authorized VMAC dealer for a
replacement part.
Relief valve failure can result in air/oil tank over
pressurization leading to system failure or rupture.
Replacing the Air 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.
1. Clean loose debris from the area around the compressor and the
filter cover to prevent contamination entering the compressor.
2. Remove the filter cover retaining nut, the filter cover and the filter
element.
3. Immediately cover the air inlet opening by masking with tape or
with a clean cloth to prevent contamination. Do not use
compressed air or perform any other tasks around the
compressor until the filter and cover are replaced.
4. Clean the inside of the filter cover with a clean, dry cloth. Do not
use flammable solvents to clean the inside of the cover. If you
do use solvent, rinse the inside of the cover thoroughly with fresh
water and dry it before installing the cover.
5. Remove the cloth or masking and install a new air filter. Make
sure that the filter fits over the machined step on the housing.
6. Replace the cover and secure it with the cover bolt. Do not over-
tighten the bolt.
Never attempt to clean the filter element with compressed
air. Replace the filter element.
