CHART EXAMPLE #1
We will use the parameters chart to set up the saw for cutting 8” (200mm)
diameter #1045 Carbon Steel.
STEP 1 – DETERMINE EFFECTIVE MATERIAL WIDTH (w) (INCHES) OR
(mm)
Effective material width W (in.) for most common shapes of materials is the
widest solid part of the material to be in contact with blade during cutting.
For simple shapes, as illustrated on the chart, this can be directly mea-
sured. For bundles of tubes and structurals, measuring the effective width

NOTES:
1. Both effective material width and guide arm width are used in setting the saw.
2. Guide arm width is the distance between the
guide arms and is used in STEP 2.
3. Effective material width, as determined here
in STEP 1, can be considered as the average
width of material “seen” by each tooth, and it is
used in STEPS 3 and 4. In Example #1, for an
8” (200mm) diameter solid, Effective Material
Width is 8” (200mm).
STEP 2 – SET FEED FORCE LIMIT
The Feed Force Limit is the maximum amount of force
with which the head is allowed to push the blade into the
work piece. Feed Force Limit should be set with the head
in the down mode, according to the label.
CUTTING SOLIDS
For cutting solids, the wider the section, the less FF
should be set, to avoid blade overloading. See the graph:

CUTTING STRUCTURALS
A reduced Feed Force Setting is used when cutting structurals.

STEP 3 – DETERMINE OPTIMUM BLADE PITCH – TEETH PER INCH (T.P.I.)
Selecting a blade with proper tooth pitch is important in order to achieve optimal cutting rates and good blade
life.
