Changing test oil
!
Before replacing the test oil, the EPS 118 must be
turned off and disconnected from the mains voltage
system.
!
During use, the test oil is subject to the effects of
evaporation, temperature, pressure, oxidation and
the impact of foreign matter. Regular checking is
therefore essential to ensure compliance with the
necessary test oil quality standard when checking
injectors. Change the test oil at regular intervals
(see maintenance intervals). Always immediately re-
place cloudy test oil even if the change interval has
not been reached. Contaminated test oil can result
in biased measured values and damage both the
EPS 118 and injectors during testing.

Procedure:
1. Switch off the EPS 118.
2. EPS 118 to be disconnected from the mains.
3. Connect the hose assembly (fig. 36, item 2, not in-
cluded in the scope of delivery) to the shut-off valve
(fig. 36, item 1). The shutoff valve has a 1/8" thread
for connecting a hose fitting.
4. Place the other end of the hose assembly in an oil
collector (fig. 36, item 3).
!
Test oil starts to run through the hose assembly
immediately after releasing the shut-off valve. Always
place the end of the hose assembly in the oil collec-
tor beforehand.
5. Open the shutoff valve (fig. 36, item 1) and let the
test oil drain until the test oil tank is completely
empty.

If the test oil is poured in too quickly, it may run out
at the filler port. Immediately clean up test oil spills
with a cloth.
Only fill the EPS 118 with test oil according to
ISO 4113. Never use diesel fuel.
The test oil level must be both above the mark of
the oil level indicator (fig. 1, item. 4) and within the
sight glass. If the test oil level cannot be seen in the
within the sight glass, too much test oil has been
filled, which will distort the measured values.
