General
Cleaning
Do not clean the PM400 with running water.
Danger to life through current surge.
Use only a cloth moistened with water.
Solvents are not permitted.
Maintenance (monthly)
In order to guarantee operating reliability of your PM400 the
following maintenance work should be carried out from time to
time, however at the latest monthly:
Check roller 1 of the closing pin for easy running and
oil if necessary, e.g. with sewing machine oil.
Clean magnets 2 on closing pin.
Check threaded spindle 3 and locking sleeve 4 for easy
running. A drop of oil usually helps.
Easy running of the threaded spindle and locking sleeve is
necessary for reliable clamping of the milling cups.
Locking sleeves which do not automatically slide downwards
through spring tension cannot reliably prevent the threaded
spindle from becoming loose. The milling cups can then be
ejected.
Easy running of roller 1 on the closing pin is necessary for
reliable closing of the housing lid of the PM400.
The thickness D1 of the three spider supports
should be checked for wear from time to time, at
the latest monthly.
This should not drop below 7.5 mm for the PM400.
The height H1 of the locking strips should be
checked for wear from time to time, at the latest
monthly.
This should not drop below 17 mm.
Check the rubber gasket 5 in the thrust piece for
wear and firm seating (adhesion). Up to 120°C use
temperature resistant quick-acting adhesive DELO
2256.
If the values drop below D1 and H1 operating reliability is
no longer guaranteed.
The milling cups can be ejected.
