Protecting the
hose from dirt
When storing the hose
• Close the hose ends (1) with the caps (2).
Connecting
the hose
• Only use a hose with a connecting piece.
• Remove the caps (4).
• Put the hose end into the receptacle (3).
• Remove the cap from the gauge port (1) and screw the connecting
piece (2) on to the gauge port – the gauge port opens.

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 during the sampling process.
The laboratory 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 container.
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 receptacles. Wipe up any
consumables that escape.
Store/dispose of consumables and any soaked equipment properly.
Ask about the applicable regulations.
