Adjustment procedures
3. Assembling the cloth chip and chain-off thread suction device
(1) Fix two tube clips ❶ to mounting plate ❹ with screws ❷ and
fitting lock nuts ❸ .
(2) Fix mounting plate ❹ with (tube clip) installing wood screws ❺
so that tube clips ❶ face the operator's side at the bottom face
of the table while satisfying the dimensions of the table shown
in the figure.
(3) Fit waste remover body ❻ to tube clips ❶ which have been
fixed in step (2), fit muffler ❼ and hose clamp ❽ to waste re-
mover body ❻ , and tighten it with hose clamp ❽ .
4. Connecting the flexible hose
(1) Cut flexible hose ❾ to a length required for connection on side
A. In case of MF-7900-H22/23, attach it to cloth chip pipe (asm.)
 and waste remover body  .
In case of MF-7900-E11, attach it to pipe (asm.)  and waste
remover body  , and clamp each with hose clamp  .
At this time, take care not to allow the flexible hose to
excessively slacken.
(2) Then connect muffler  on side B and reducing socket  with
the remaining flexible hose ❾ . At this time, also cut the hose to
an appropriate length. After connecting the tube to them, clamp
them with hose clamp  .
(Caution) The flexible hose ❾ is slightly too long to provide
a margin, however, cloth chips may remain in the
middle of the hose if the hose slackens excessively.
So, do not make the hose longer than is necessary or
slacken it excessively.
