4-1 UNPACKING
All the parts of the MEZZO stereo-microscope have been carefully packed so that they
reach you in perfect condition. We recommend that you retain the original packaging as
this will be needed if ever the device needs to be sent in, if you intend to store the item
for a longer period, or if it needs to be transported to a technical service centre for
servicing or repair.
The packaging of the MEZZO comprises the following items:
Microscope head with mount and LCD glare protection filter (4.2 Fig.1 - 10)
Two eyepieces with eyepiece covers (4.2 Fig. 2 - 1)
Supporting arm (for holding the welding hand-piece), with integrated LED light (4.2
Fig.12)
Bearing rod (4.2 Fig.1 -11)
Base plate, for attaching the bearing rod (4.2 Fig.1 -13)
Protective cover
Tools for adjusting the focussing levels
Remove and handle all microscope components with great care.
Avoid touching the lenses and optical elements. Also avoid contact with dust, water or
any other substances that could soil or damage the surface of the lenses and impair the
quality of the image.

SETUP INSTRUCTIONS AND COMENCING WORK
All stages of the microscope assembly must be carried out with great care. The
individual parts must not be put together using excessive force.
Mount the bearing rod (11) to the base plate (13), using the bolt that is included; tighten it
with an open-ended spanner. Place upright, on a clean, flat, and stable surface.
Slide the supporting arm (12) over the bearing rod (11) and secure it slightly above the
middle of the rod, tightening hand tight.
Slide the microscope head (8) and its mount with retaining screw (9) over the bearing rod
(11), and secure it at about “3 fingers” width above the supporting arm for the hand-piece
(12).
Insert the eyepieces (1) with eyepiece covers, and secure them with the locking screw
(4).
Attach the “control lead for LCD glare protection filter (Shutter)” (15), to the back of the
welding device. (Observe the guidelines in the instruction manual of the welding device).
Connect the LED light with the PUK 3s.
Insert the mains cable (16) into the connection socket marked “LED-Lamp 800 mA”, on
the back of the welding device.
Note!
Always test that the LCD glare protection filter (Shutter) (6) is working correctly
before you start welding.
By pressing in the rotary knob
“
Power
”
, of the “PUK U3” welding device, the
shutter can be tested. During this process it will change from its clear setting to its
dark setting, and back again.
If the LCD glare protection filter (Shutter) doesn’t change from its clear to dark
setting, then it must be exchanged straight away. No welding may be done unless
the microscope has a fully functioning shutter.
