WIRING
WIRING
Cost includes wiring for either of the following standard electrical systems.
110 or 220 volt single phase
220 or 440 volt three phase
Hook up lead-in wires and switch Motor on
to check the direction of Flywheel. It should
operate in a counter-clockwise direction as
indicated by the arrow.
If the lead-in wires have been incorrectly
hooked up, Tripping Mechanism will fail to
operate. To remedy this, simply reverse any
two lead-in wires.
SETUP PROCEDURE
POWER NOTCHER
Except for wiring, the power operated Di-Acro Notcher is delivered ready for operation. To set up,
simply hook up wiring, adjust Gauges for the proper size notch and machine is ready for production.
CAUTION
TO PREVENT SERIOUS BODILY INJURY
AND DAMAGE TO THE MACHINE
BOLT THE MACHINE TO THE STAND
AND THE STAND TO THE FLOOR
Smooth, even notches can be cut in all types of ductile material with the Di-Acro Notcher. It eliminates the high cost of special dies required for each different notching operation and does away
with time wasted in punch press setup—you simply adjust the Material Gauge and you’re ready for
production.
Both power and hand operated models of this precision machine are available. They are equally
useful in the experimental shop or on the production line.
Adjustable gauges are used to locate a notch of any dimension at the corner of a sheet of material
or at any position along the edge of the sheet. Notches greater or less than 90 degrees can be
obtained in two operations and many straight shearing operations can also be performed. The
hardened and ground Triangular Ram used in the Di-Acro Notcher will provide years of continuous,
trouble-free performance and assure a clean cut free from rough edges or burr.

SETUP
SETUP
A. Change size of tab (set at factory for 1/2” tab)
Loosen bolts (A) holding lower blade to blade
1.
carrier (do not remove).
Slide blades forward or back, holding them
2.
against shoulder machined in blade carrier to
obtain desired tab.
Tighten bolts (A).
3.
Loosen bolts (B).
4.
Lower ram until upper blades pass by lower
5.
blades (it may be necessary to slide one upper
blade back).
Slide blade (C) forward into notch in lower
6.
blade. Tighten bolts.
Slide blade (D) forward until it contacts blade
7.
(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
1.
depth, reading scale along edge (E).
Note: Scale is set to read from the edge of the
notch so tab size must be subtracted to obtain
a corner notch of equal depth.
To notch along the side of a sheet, remove
2.
gauges and turn them upside down. Screws will
fit in outside slot when gages are set parallel to
each other.
C. Shearing long strips full width
Remove lower left blade and adjust right blade
1.
to maximum tab size.
D. Setting depth of stroke
With power off, step on foot pedal and turn
1.
flywheel by hand until ram is at bottom of
stroke.
Remove pin (N) and loosen lock nut (O)
2.
Lower ram by hand until upper blade is 1/16”
3.
below edge of lower blade.
Adjust connecting rod link on shaft until pin (N)
4.
will re-enter hole. Re-tighten lock nut (O).

MAINTENANCE
A. Sharpening blades
1.
Blades are dual edged. A new cutting edge is
obtained by changing right blade to left side and
visa versa.
2.
If only a slight amount of sharpening is required,
grind wide edge only, as this will eliminate necessity of resetting clearance.
3.
When grinding ends be sure to maintain angle
presently on blade.
4.
Reset scale to zero, lining up zero on scale with
straight edge along blade cutting edge
B. Adjusting blade clearance
1.
Remove table.
2.
Loosen blade mounting bolts A and B.
3.
Loosen blade carrier bolts J.
4.
Adjust lower blades to required tab (per
instructions, A-1, 2, 3, under SETUP).
5.
Set upper blades for no tab or a tab smaller
than set in lower blades.
6.
Back off screws K and pull blade carrier
away from top blade.
7.
Move ram to bottom of stroke.
8.
Turn in screws K by hand pushing blade in
until it contacts upper blade. Placing a shim
or piece of paper between blades will provide clearance to prevent rubbing of
blades. Too much clearance will cause burr
on workpiece. Excessive rubbing of blade
will reduce blade life.
9.
Tigten bolts J.
10.
Set upper blade to tab notch in lower blade
and tighten.

LUBRICATION
1.
Lower unit of 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.
3.
Clutch linkage - oil occasionally.

TROUBLE SHOOTING
Problem: Double tripping, or not stopping at
end of single cycle.
Cause: Brake too loose, causing dog to
coast on by release lever.
Remedy: Tighten brake adjustment.
Cause: Brake too tight, or ram binding,
causing release lever to slip by instead of
pulling clutch dog.
Remedy: Loosen brake, or remove pin
N and check for binding in ram. If
binding remove cap and remove burrs
and polish ram until it is operating
freely.
TROUBLE SHOOTING
Problem: Machine will not operate when pedal
is depressed.
Cause: Clutch dog binding, or broken
spring.
Remedy: Rotate flywheel by hand to
bottom of stroke: Remove brake collar
and brake assembly. Remove screw R
and pin S. Pull out clutch dog. Remove
burrs particles. Replace spring is weak
or broken. (To replace clutch dog
remove bolts T and slide flywheel in
direction indicated by arrow. Insert
clutch dog and pin S. Tighten screw R.
Slide flywheel back into place and retighten bolts T.)
