Check that all the sealing surfaces are
clean.
Brush the threads of the bolts clean, using
a steel wire brush. Lubricate the threads
with a thin layer of grease, e.g. Gleitmo
800 or equivalent.
Attach gaskets to the plates or check that
all the gaskets are properly attached.
Insert the plates with the herring bone pat-
tern positioned in alternate directions and
with the gaskets turned towards the frame
plate.
Press the plate assembly together. Tight-
ening is done in two steps, see figures be-
low. Be careful so that the frame plate and
the pressure plate are always in parallel.
Step 1: Tighten the two diagonal pairs of
bolts alternately until the plate package
measures 1,10A.
Step 2: After that bolts are tightened alter-
nately and diagonally, as shown in the fig-
ure below. Check the dimension A during
tightening at the positions of the bolts that
are being used.
Note!
If the gasket is wrongly positioned, it will
show by the fact that it rises out of the gas-
ket groove or that it is positioned outside
the groove.
