Lubrication
The roller bearings are
maintenance-free. They
must be replaced if they get
noisy.
Change the oil whenever it
contains water or is
contaminated. Change the
oil at least every two years.
If refilling is required, see
section

Oil.
The gear teeth and the
bearing bushes must be
lubricated twice a year with
an all-purpose grease.
When tightening the
screws, renew the
threadlocker if necessary.
Inspection
Check the power supply
cable twice a year for
surface damage, strain,
kinks, etc.
If damaged, the cable must
be replaced by Grundfos.
If the shaft seal housing is
not monitored for the
ingress of water, we
recommend that you make
inspections every 6
months.
Check the impeller
regularly for wear and tear.
Remove any material
wound round the impeller,
such as ropes, threads, etc.
which may cause uneven
running and oscillation of
the installation. In case of
strong turbulence, cleaning
is absolutely necessary.
Check the wire regularly
and always before using
the winch. Replace the
wire, if required.
