The parts in need of consistent interval change out are the external & internal filters and the
O2 sensor. The intervals, tools needed, part #’s, and other maintenance tips for instrument life
are described below:
1) Internal Filter; part #: EMS-5093; 90 DAY (3 month min.) Interval.
·

cutter .

Remove the 11 or 12 #6 button head screws with 2mm allen. Be careful not to
strip allen head when loosening & ONLY FINGER tight when tightening.
·
Remove the cover, int. filter located in the back right, cut off zip ties and use
needle nose pliers to remove the hose. Install new filter and attach two (2) new

External filter is located on the back side angle bracket, remove the water drain
hose from the bottom of the filter, turn counter clockwise to loosen and remove.
Before attaching the new filter, moisten the rubber gasket with H2O or best
saliva, screw filter clockwise to tighten. Make sure the filter goes on straight, this
is the most common point for leaks!

Re-attach the drain hose to the bottom of the filter. Note some shops have the
new water trap before the external filter now, this arrangement only has a 1/4
plastic cap sealing the external filter drain! Take the cap off the old filter before
discarding and re-attach to the filter drain.
