plate (A5).
350 and 700 cm²: undo the latch of the
hose clamp (A6). Take the compressor
(A19), hose clamp (A6) and diaphragm
(A4) off the diaphragm plate (A5).
5. Mount the new diaphragm (A4). Make
sure the diaphragm is correctly aligned
with the diaphragm plate. The imaginary
line through two opposing recesses for
springs on the diaphragm plate must be
aligned centrally between two bolting
holes in the diaphragm (see Fig. 9-2).
6. Place the hose clamp (A6) evenly into the
groove in the diaphragm (A4) intended
for it.
7. 240 cm²: turn the screw on the latch of
the hose clamp until the hose clamp rests
completely in the groove. Tighten the
screw of the latch using a suitable tool.
Observe tightening torques.
350 and 700 cm²: turn the screw on the
latch of the hose clamp until only a gap
of just a few millimeters remains between
the diaphragm (A4) and hose clamp
(A6).
Place and align the compressor (A19)
beneath the clamp's latch (see Fig. 9-2).
Tighten the screw of the latch using a
