must
be bolted to work bench. If floor stand has been
provided, machine must be bolted to floor stand with bolts provided. Stand

lagged to floor.
1. Mount and level Notcher with drop-out overhanging edge of bench and bolt or lag in place.
Lubricate all points with SAE 30 machine oil before operating.
2. Upper Standard Blades - (17) and (18) are set at factory for “pierce” cutting, starting at apex or
corner of inside cut. To change to “splay” cutting, interchange blades (17) and (18) end for end
so that cut starts at outside edge of sheet. Align blades at point (elongated holes are provided
in blades for this purpose) before tightening blade bolts (16) securely.
3. Lower Standard Blades - (28) and (29) are each symmetrical and can be mounted to use all 4
cutting edges. Blades are positioned by blade bolts (32) from underneath table.
4. Blade Adjustment:
a. Take off table (21) by removing two table screws (27). Position the slide at bottom of
stroke.
b. Loosen lower blade bolts (32) slightly.
c. Turn blade adjusting screws (26) mounted in adjusting plate (25) to bring blade to .002
normal clearance between upper and lower blade. (Clearance should be greater for heavy
stock - less for thin stock).
d. Tighten blade bolts (32) securely.
e. Remount table.
5. Tab Notching - To install tab blades:
a. Remove table (21) as in 4a and disassemble four standard blades.
b. Install top right hand (18T) and left hand (17T) tab blades using the 3/8” socket head cap
screws furnished with tab blade kit. (Use one 3/4 long screw (16T) in front hole of each
blade.) Tighten screws finger tight until blades are properly positioned.
c. Top right hand blade should protrude past the edge of the left hand blade the desired depth
of notch. Tighten all screws securely.
d. Mount lower blades (28T & 29T), using blade plates (30T & 31T) furnished with kit, leaving
screws finger tight until proper setting is attained.
e. Position slide at bottom of stroke, taking care that lower blades are back, clear of the
upper blades.
f.
Set lower right hand blade so that front cutting corner is in line with front corner of the upper
right hand blade with the normal clearance of .002” between them. Tighten right hand
blade screws securely.
