SERVICING PERSONNEL
Before repair
of
microscopes
of
VM
series:
Although this repair manual refers
only
to
the methods
of
repair
and
adjustment
of
VMT-4, VMT-2
and
VMZ
of
the VM
series,
it
also
enables
you
to
understand those
of
VMF.
Listed
in
this repair manual
are
a variety
of
tools
and
jigs,
without
which the required optical adjustments
are
not
possible.
lt
is,
therefore, requested that the optical system
not
be
disassembled
unless
the
necessary
jigs
are
available.
Requisites
for
repairs:
1.
First
of
all, ascertain what parts
of
the microscope the
user
or
owner
of
which wishes you
to
repair.
2.
Never fail
to
check the entire function
of
the microscope before you commence its repair.
a)
Find
out
what parts
are
defective
and
how much they
are
damaged.
b)
Prior
to
repair,
think
of
the
best
possible order
of
disassembling the defective parts in a most
efficient way.·
3.
After
completing the repair, check the functions
of
not
only the
re-assembled
parts
but
also
the entire
microscope
to
make
sure
no defect should
be
left
unremedied.
4.
Be
careful
not
to
deform repair parts during the assembly; make
it
practice
to
use
tools
and
jigs
speci-
fied
for
purpose.
5.
Make repairs
promptly
and
accurately.

In case of repairing a small number of the microscopes, expensive KN0027 can be substituted by
regular GWlOX or GWH10X eyepiece which is attached to the microscope. Although accuracy
somewhat deteriorates as a result, it is not to such an extent as to adversely affect observation
through·the microscope.
