7.8 Topping up test oil
The test oil must be topped up if the level in the test
oil tank drops below the mark on the oil level indica-
tor (Fig. 1, item4).
1. Remove the screwed drain plug from the test oil
filler port (Fig. 3, item9).
! 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.
2. Pour test oil (ISO4113) through the funnel very
slowly and carefully into the test oil filler port
(Fig. 3, item9). Add test oil until it is above the
mark on the oil level indicator (Fig. 1, item4).
3. Screw the knurled nut clockwise into the test oil
filler port (Fig. 3, item9).
" The EPS 118 is ready for operation.
