Preface
You are now the owner of a
Logosol M7 Portable Sawmill,
the result of our collective
experience and dedicated
efforts since 1988. There are
currently more than fifteen
thousand Logosol Sawmills in
use in Sweden and the rest of
the world, making the Logosol
Portable sawmill the top seller
world-wide.
The goal for Logosol’s develop-
ment effort is to design smaller
and lighter machines that
solve a task intelligently, but
without lowering the quality of
the nished product. To top it
off, Logosol products must be
affordably priced so as to make
them available to everyone
working with wood.
Logosol produces a large range
of products, enabling a single
person to handle the entire
production chain from forest
felling to nished product.
In addition to various sized
sawmills, the range includes such
products as a multi-sided planer
providing excellent proling. For
more information on Logosol
products and accessories, send
for our catalogue.
For us, the most important
consideration is that you are
100% satisfied with your M7
Portable Sawmill. If you have
any questions or thoughts about
the sawmill, please do not
hesitate to contact us.
In closing, I wish you much
enjoyment and success with
your future building projects.
Bengt-Olov Byström
Managing Director,
