Logosol M7 - Check Parallelism of Log Bed and Guide Bar

5. Check the parallelity
between the log bed and the
guide bar.
Push the saw unit (without
the chain mounted) onto the
sawmill. The measurement
between the guide bar and
the log bed is to be 52 mm
(2.05”) at both the inner and
the outer end of the log bed.
Push the log bed outwards
when measuring. If you do not
get the same measurements
at both the inner and the outer
end of the log bed, you have
to adjust this.
Remedy: Place schims
between the bottom plate
of the saw carriage (or the
E 5000) and the aluminium
slide profiles. The schims
should be 15-20 mm (0.6”-
0.8”) wide and of a length that
allows them to t in between
the screws that hold the slide
proles. Turn the screws a
couple of times, so that you
can insert schims from the
side, but make sure that the
square nuts that are in the
slide profile do not come
loose from the screws. Only
place schims in one slide
prole. Place equally many
pieces of schims between
each screw and at the end of
the slide prole to ensure that
the bottom plate will not be
35
inclined when the screws are
tightened. Check the angle of
the guide bar. When you get
the same measurements at
the inner and the outer end
of the log bed, the adjustment
is done. If necessary, adjust
the height of the log bed
according to the instructions
on p.23.
Congratulations! Now
you have an exceptionally
accurately adjusted M7
Sawmill.
If you are careful with the
sawmill, it will stay adjusted
for a longer time. Provided
that the cutting equipment is
in good condition, deviations
will be due to sagging timber
or tensions in the wood.
To increase the precision
when such problems occur, we
recommend the accessories
Cross support (no. 4500-
070-1000), Log Fence with
Support (no. 4510-720-6104)
and Log End Support (no.
4507-001-2010).
