9. Inspect and Clean the Oil Drain Filter
[6] Maintenance 9.
At least once a month check the oil drain filter case on the back of the
dentist’s tray and see if it is full.
Follow this procedure to clean the filter and case if they are full of oil. Also
check to see if the exhaust air for the air turbine is operating properly.
Place a bucket underneath the case to catch the oil in-
side it.
(1)Take off the filter case and empty out the oil.
Hold the top of the filter case and then turn the case itself to loosen it
up.
Soak up the oil with absorbent paper and dispose of it
according to regulations for flammable materials.
(2)Remove the oil drain filter and the top of the case.
Pull the filter off and then unscrew its support column.
(3)Wash all the components with running water and
then completely dry and remove all remaining moisture. Replace the
top of the filter case and the filter support column.
(4)Check the Exhaust Air for the Air Turbine Operate each of the air turbine
handpieces and hold your hand near the support column for the hand-
piece to see if air is coming out.
If the exhaust air does not flow properly, stop using the
handpiece and contact your local dealer or the J.Morita
Corp.
More water will tend to mix with the exhaust air if the
o-rings on the connection end of the air turbine hand-
piece are broken. Make sure these o-rings are in good
shape.
(5)If everything is in order, reassemble the filter and its case.
