OPERATOR’S MANUAL & INSTRUCTIONS

Smooth, even notches can be cut in all types o ductile material with the Di-Acro Notcher. It elimi-
nates the high cost o special dies required or each di erent notching operation and does away
with time wasted in punch press setup—you simply adjust the Material Gauge and you’re ready or
production.
Both power and hand operated models o this precision machine are available. They are equally
use ul in the experimental shop or on the production line.
Adjustable gauges are used to locate a notch o any dimension at the corner o a sheet o material
or at any position along the edge o the sheet. Notches greater or less than 90 degrees can be
obtained in two operations and many straight shearing operations can also be per ormed. The
hardened and ground Triangular Ram used in the Di-Acro Notcher will provide years o continuous,
trouble- ree per ormance and assure a clean cut ree rom rough edges or burr.
SETUP PROCEDURE
POWER NOTCHER
Except or wiring, the power operated Di-Acro Notcher is delivered ready or operation. To set up,
simply hook up wiring, adjust Gauges or the proper size notch and machine is ready or production.
WIRING
Cost includes wiring or either o the ollow-
ing standard electrical systems.
110 or 220 volt single phase
220 or 440 volt three phase
Hook up lead-in wires and switch Motor on

SETUP
A. Change size of tab (set at factory for 1/2” tab)
Loosen bolts (A) holding lower blade to blade
carrier (do not remove).
Slide blades orward or back, holding them
against shoulder machined in blade carrier to
obtain desired tab.
Tighten bolts (A).
Loosen bolts (B).
Lower ram until upper blades pass by lower
blades (it may be necessary to slide one upper
blade back).
Slide blade (C) orward into notch in lower
blade. Tighten bolts.
Slide blade (D) orward until it contacts blade
(C). Tighten bolts.
(Note: A slight opening at (H) is normal to insure
contact at cutting edge.)

B. Setting size of notch
Loosen screws (G) and set to required notch
depth, reading scale along edge (E).
Note: Scale is set to read rom the edge o the
notch so tab size must be subtracted to obtain
a corner notch o equal depth.
To notch along the side o a sheet, remove
gauges and turn them upside down. Screws will
it in outside slot when gages are set parallel to
each other.

D. Setting depth of stroke
With power o , step on oot pedal and turn
lywheel by hand until ram is at bottom o
stroke.
Remove pin (N) and loosen lock nut (O)
Lower ram by hand until upper blade is 1/16”
below edge o lower blade.

Lower unit o Notcher is equipped with oilite bronze
bearing requiring occasional lubrication at points
indicated in photos. (Rocker arm not shown)
Upper unit should be oiled daily at points indicated.
Clutch linkage - oil occasionally.
MAINTENANCE
A. Sharpening blades
Blades are dual edged. A new cutting edge is
obtained by changing right blade to le t side and
visa versa.
I only a slight amount o sharpening is required,
grind wide edge only, as this will eliminate neces-
sity o resetting clearance.
When grinding ends be sure to maintain angle
presently on blade.
Reset scale to zero, lining up zero on scale with
straight edge along blade cutting edge

B. Adjusting blade clearance
Remove table.
Loosen blade mounting bolts A and B.
Loosen blade carrier bolts J.
Adjust lower blades to required tab (per
instructions, A-1, 2, 3, under SETUP).
Set upper blades for no tab or a tab smaller
than set in lower blades.
Back off screws K and pull blade carrier
away from top blade.
Move ram to bottom of stroke.
Turn in screws K by hand pushing blade in
until it contacts upper blade. Placing a shim
or piece of paper between blades will pro-
vide clearance to prevent rubbing of
blades. Too much clearance will cause burr
on workpiece. Excessive rubbing of blade
will reduce blade life.
Tigten bolts J.
Set upper blade to tab notch in lower blade
and tighten.
