4.4 INLET AIR FILTER
To check condition of the inlet filter, run compressor in
the LOADED mode and observe “Inlet Filter” on the
CURRENT STATUS display screen. If the display says
“Inlet Filter OK”, then no maintenance is required. If “ ? ”
is flashing on the screen and the display says “CHANGE
INLET FILTER”, then the inlet filter should be changed.
To change inlet filter elements, loosen wing nut on top of
inlet filter housing. Lift cover up and away to expose
element/s.
Carefully remove the old element/s to prevent dirt from
entering the inlet valve. Discard old element/s.
Thoroughly clean the element housing and wipe all
surfaces.
Install new element/s and inspect to ensure that they
have seated properly.
Install top of inlet filter housing.
Inspect the rubber seal on the retainer wing nut and
replace seal if required.
Tighten wing nut.
Start machine and run in the load mode to verify filter
condition.
4.5 COOLANT FILTER
To check the condition of the coolant filter, the
compressor must be running. Observe “Injected
Temperature” on the CURRENT STATUS display screen.
If the temperature is less than 120°F (49°C), continue to
run the machine. When the temperature is greater than
120°F (49°C), observe “Coolant Filter” on the screen. If
the display says “Coolant Filter OK”, then the filter does
not need service. If “ ? ” is flashing on the screen and the
display says “CHANGE COOLANT FILTER”, then the
filter should be replaced.
Use a suitable device and loosen the old element. Use
drain pan to catch any leakage during removal. Discard
old element.
Wipe the sealing surface of the filter with a clean, lint-free
rag to prevent the entry of dirt into the system.
Remove the replacement element from its protective
package. Apply a small amount of clean lubricant on the
rubber seal and install the element.
