7. Operational Use
ADJUSTMENT OF THE ERGO EXTRACTION ARM
:
Prior to the operational use, it is important to install the ERGO extraction arm on the work-
table by means of 6 nuts belonging to the mounting pins, and then follow subsequent
steps:
1.
Make sure if the ventilation installation is functioning.
2.
Set the hood inlet in a suitable position appropriate for fume- and dust control and
simul-
taneously
not causing barrier
to operator’s movement and not limiting the field of view at
the workplace.
By turning the
shut-off damper lever
, adjust the intake air volume most accurate to capture
efficiently the fume and dust.
Pay attention
,
the volume flow
cannot be too high, as it could
produce excessive draught.
During the operational use, the position of the hood, extraction arm and the shut-off dam-
per can be changed many times
– currently adjusting them to the needs of operator.
Each joint
is equipped with a frictional brake
to stabilise the extraction arm and keep
it in the
the requested position
(self-supporting features)
during the operational use.
Fig. No.4
The adjustment of the frictional brakes is carried out by increasing or reducing the tension
of the disk-springs
upon the frictional elements
. To increase the frictional moment tighten up
the nuts, whereas releasing the nuts reduces the pressure tension.
The brake adjustment
in the subsequent joints
ought to be executed
in such a way that
ensures
the stability and self-supporting features of the extraction arm (which is important to keep the
stable arm position), whereas, on the other hand this cannot cause any excessive resistance
while User is changing the arm position.
