Do not use any solvents or abrasive cleaners on the front

Pneumatic System

Compressed Air Filter

Under normal operating conditions, the filter (5 micron ele-
ment) should only need to be replaced every two years or
when the pressure drop exceeds 15psi (0.1MPa) whichever
comes first. Replacement filers are available from SMC
Corporation of America (Part No. AF30P–060S). Before
attempting to replace the filter, turn off the compressed
air supply, and then disconnect the air supply from the
filter inlet. The metal canister and polycarbonate bowl
must be removed to gain access to the filter element. Care-
fully remove the water drain line from the bottom of the
housing before removing the filter canister. The hose fitting
can be easily snapped off if bent to far.
To remove the canister, pull and hold the spring-loaded
black release tab down as shown in Figure 11-1. Turn
the canister 45° either to the left or right, then pull straight
down. The filter element is installed under the regulator
housing. Twist the filter retainer 90° (Figure 11-2) and
pull it down to remove the filter. Install a new filter ele-
ment and replace the retainer. Reinstall the filter canister
by holding the black release tab down and inserting the
housing vertically, but rotated 45° off center. Still holding
the spring-loaded tab down, push the canister up as far as it
will go. Turn the canister 45° until the locking tab is under
the alignment mark. Release the tab and it will click into
the locked position. Carefully reinstall the water drain hose.

Moisture Trap

The metal cage below the pressure gauge covers the
polycarbonate moisture trap. The trap features a normally
closed float and is self- d raining of accumulated water. A
drain hose is attached to the bottom of the filter housing
which exits at the bottom of the machine.
