8.2.6 Changing test oil
!
Before changing the test oil, the EPS 205 must be
switched off and disconnected from the three-phase
AC network.
!
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
nozzle-and-holder assemblies and injectors. The test
oil must always be replaced if it is considerably dark-
er than in the as-new condition. Contaminated test
oil can result in biased measured values and damage
both the EPS 205 and injectors/nozzle-and-holder
assemblies during testing.
Authorized types of test oil:

Test oil starts to run through the hose immediately
after inserting the quick-release coupling at the
EPS 205. Always place the end of the hose in the oil
collector beforehand.
6. Place the end of the 1.5 m hose (Fig. 42, item 4;
1 680 712 283) without quick-release coupling in the
oil collector (Fig. 42, item 3).
7. Insert the 1.5 m hose with quick-release coupling
(1 680 712 283) in the quick-release coupling of the
test oil tank (Fig. 42, item 1).
