8.2 Suitable fluid
The oil grades to be used are described in ISO 3448 Type
HM 32.
NOTE
Damage to components caused by fluids without
sufficient levels of corrosion inhibitor!
The components made of steel materials must be
protected before the usual oxidation process.
Only ever use fluids with sufficient levels of corro-
sion inhibitor.
NOTE
Damage to materials caused by dirty / unprepared
fluid!
For the product to function properly, ensure that
the fluid is cleaned / processed, and that it con-
tains no particles measuring >10 microns [filtered
with a mesh width of 10 microns].
NOTE
Damage to seals caused by the wrong fluid!
Do not use any fluid that attacks and damages the
installed sealing elements. Those installed seal-
ing elements can be made of NBR, Viton and
PUR materials.
Always use ester-free and non-polar fluids.
8.3 Checking the total stroke
WARNING
Serious crushing injuries caused by moving parts
when stroke positions are being tested!
Set the machine into set-up mode.
Reduce the operating pressure to a minimum.
Never reach into moving parts.
Pay attention to the gap dimensions of moving
parts.
Prior to commissioning, check the complete stroke to ensure
that there is sufficient reserve stroke and opening stroke.
For this, the same measurement of the moving part must be
performed at fixed points in front and rear limit positions.
Then deduct the value obtained in the rear limit position from
the value obtained from the front limit position. This figure
must then be equal to or greater than the nominal total
stroke.
