Danger of contamination of the oil sample!
If the hose with the connecting piece is dirty, the dirt can contaminate the
oil sample in the sample container durin
g the sampling process. The labo-
ratory analysis would then be incorrect.
For flushing, always allow 2 litres (0.5 gal) of oil to flow through the hose
into a receptacle before filling the sample con
tainer.
O
Danger due to escaping hydraulic oil!
When you screw the connecting piece on to the gauge port, the gauge port
opens and oil flows out of the hose
. Put the hose end into a receptacle
before screwing on the connecting piece.
Always let consumables drain into suitable recept
acles. Wipe up any con-
sumables that escape.
Store/dispose of consumables and any soaked equipment properly.
Ask about the applicable regulations.
