4.3.3 Exhaust Pump Filter
(1) Replacement method
Replace the filter every 3000 hours, or when the exhaust power
has degraded. If the filter gets clogged, the pump output becomes
low. Fig. 4.3.3 shows where the filter of a exhaust pump is
located.
1) Stop the oscillator, and turn off the power.
2) Remove the maintenance panel.
3) Remove the black screw button from the pump.
4) Remove the filter cover and O-ring.
5) Remove the spring and washer.
6) Pull out the exhaust filter element.
7) Orient a new exhaust filter element correctly, and reverse
the procedure from step 6 to step 3. (An upward arrow is
indicated on the front surface of the filter element.)
NOTE
The exhaust filter element should be installed
securely. If it is installed incorrectly, or the O-ring is
not inserted accurately, oil mist (white) will come
out from the exhaust outlet.
8) Put the maintenance panel back in place, and turn on the
power.
