1. INTRODUCTION
The purpose of this manual is to provide in-
structions for the installation, operation and
maintenance of your Model L-9 metal cutting band
saw machine, a comparatively simple but rugged
machine tool.
Any power driven machine tool constitutes a
potential hazard to the operator's safety. The
Model L-9 saw has been designed with safety in
mind, but it is still necessary to observe all the
safety rules employed in the operation of any
machine. We recommend you read the safety
manual included with this manual before you start
up the machine. CAUTION: Some guards have
been removed to show the underlying parts in the
following photos. In actual use, make sure all
Figure 1
guards are in place before operating the machine.
2. INSTALLATION
A. LOCATION. When installing the L-9 saw, it is
important that proper consideration be given to the
surroundings and location. It should be in an area
large enough for operator safety. The machine and
the work area should be properly lighted, without
severe reflections or other visibility hazards.
The L-9 saw does not normally require any special
foundations or footings. However, the floor under it
should be adequate to support the machine with its
maximum intended load. The machine should be
level and shimmed so that each foot is resting
firmly on the floor, carrying its proportion of the
load without twisting or straining the machine bed.
