OPERATION
USING THE JOB SELECTOR
1. Refer to the Job Selector chart on the left bandwheel
door for information about the recommended blade
pitch, band speed, and cutting rate. This information
is listed according to type of material to be cut and
its thickness. The Job Selector also has a checklist
for proper machine operation and saw band break-in
procedures.
2. For example: If the material to be cut is low carbon
steel which is two (2) inches (50.8 mm) thick, the
Job Selector recommends using: (a) An Imperial
Bi-Metal saw blade with 10-6 blade pitch; (b) Band
speed of 315 fpm (90 m/min); and (c) A cutting rate
of 13 square inches per minute (79 square centi-
meters per minute).
Job Selector recommendations are a general
guide for correct power sawing on a prop-
erly-maintained DoALL saw. They are based
on cutting ve (5) inch (127.0 mm) round,
annealed, scale-free stock using a 1-1/2 inch

• Vise Control: Choices are STANDARD and
NESTING.
(a) STANDARD: Allows the operator to select
“OVERLAP” or “NO OVERLAP” at the Vise Overlap
option. The minimum butt end length is set to 2.50
inches (63.5 mm).
(b) NESTING: This selection does not allow “VISE
OVERLAP” in the Vise Overlap option.
 The rst time user is advised to select the
“STANDARD” setting.
• Home Position: Selects index vise position
during cut. Choices are INDEX FRONT and INDEX
REAR.
(a) INDEX FRONT: This is preferred when using the
nesting xture and may be valuable when using
variable vise pressure. It allows the use of two vises
to provide extra clamping area. Operating sequence
is as follows: When the cut has been completed,
the index vise jaws open, the index moves to the
required dimension and transfers the stock.
(b) INDEX REAR: This is the shortest cycle time and
is preferred for most operations when not using the
nesting xture or variable vise pressure. Operating
sequence is as follows: While a cut is being made,
the index vise (with vise jaws open) moves to the
rear to position itself for the next index stroke; when
the cut is completed, the index vise jaws close, the
xed vise jaws open, and the index transfers another
stockpiece into cutting position. When the last part
in a job is being cut, the index will remain forward
until the next job has been started.
 The rst time user is advised to select the
“INDEX REAR” setting.
• Display Units: Choices are INCHES and
MILLIMETERS.
(a) Job data, kerf width, butt end length, etc. is converted
between "INCHES" and "MILLIMETERS". Inch
measurements use three places to the right of the
decimal; millimeter measurements use two places
to the right of the decimal. Conversions made
from inches to millimeters are within .01 millimeter;
conversions made from millimeters to inches are
within .001 inches.
OPERATOR WORKSTATION (Continued....)

16
• Vise Overlap: Choices are OVERLAP and NO
OVERLAP.
(a) OVERLAP: After the index has moved forward and
the xed vise jaws clamp, a time lapses before the
index vise jaws open. This selection is forced if
“NESTING” is selected in the Vise Control option.
The best accuracy is obtained when “OVERLAP”
is selected because the material is always clamped
by one of the vises.
(b) NO OVERLAP: After the index has moved forward,
the index vise jaws open at the same time as the
xed vise jaws close. This selection allows slightly
faster operation because both vises are cycled at
the same time. This selection also allows material
that has a tendency to “climb” in the vises to fall
back to the vise bed.
