Check whether the pressure has been fully
released by briefly actuating the pressure
limiting valve. Check the indicator on the
pressure gauge as you do this.
If you are sure that the pressure has been fully
released, you can now unscrew the filling hole
with a suitable tool.
Caution:
There is a sealing ring under the screw.
Use a funnel with a sieve insert to fill the
container with lubricant up to the maximum fill
level marking.
If the container is overfilled (above maximum fill
line), the excess lubricant must be drained.
Otherwise, no aerosol can be generated (see
chapter “Draining lubricant”, page 20).
Make sure that the filling hole is tightly
closed again after refilling the
container.
Make sure that the sealing ring is positioned
correctly before you screw the locking screw
back in.
Tighten the locking screw, but do not force it.
Otherwise, the seal could become damaged.
Perform a visual inspection to ensure the
tightness once the system is put into operation.
12.2 Changing lubricant
If you want to change lubricant, pour out the
previously used lubricant before filling the
container with the new lubricant. Please read
the following section about draining the
lubricant.
Do not mix different lubricants with
each other if there is no explicit
approval from SKF. Otherwise,
damages may result and a
cumbersome internal cleaning of the
system will be unavoidable.
Next, fill the container with the new lubricant as
described in the previous section.
12.3 Draining lubricant
The lubricant container has to be
depressurised before draining
lubricant.
To depressurise the container, see the
indications from section “Refilling lubricant,
page 19”.
To drain the lubricant, use a suitable tool to
release the drain screw on the underside of the
container.
Please observe the legal regulations for the
disposal of lubricants.
Make sure that the drain valve is
closed again after draining the
lubricant.
12.4 Cleaning
If necessary, the MQL system can be cleaned
with mild, compatible (non-alkaline, no soap)
cleaning agents.
For safety reasons, we recommend that you
disconnect the MQL system from the
compressed air supply and depressurise the
container as described in section “Refilling
lubricant”, page 19.
During cleaning, leave hoses and cables
connected where possible and close off all
openings so that no cleaning agent can get
inside the MQL system.
For normal operation and with use of lubricants
that are compatible with each other, internal
cleaning is not necessary.
