Operations:
Prior to using this machine there are 3/4 settings that must be adjusted
1. Grease cut/punch (for longer tool life)
2. Double check machine stock to machine capacities
3. Secure stock with material clamp/Secure guards
4. Install the proper size punch if necessary (it is the only changeable tool on the machine)
Grease Punch/Shear/Notcher
Applying grease to your shear/punch/notch will allow the tool to more easily slide through the material,
extending the tool life and quality of the cut
Please apply grease or cutting oil to either the tool or where you intend to cut
Punch –Apply grease with brush provided
Shear/Notch –Apply grease or cutting fluid along the length of your cut
Double Check Thickness Cutting Capacities –Shears/Notcher
Trying to cut too thick in to wide of stock can lead to tool damage and a large repair bill. Always check
the machine or insert tool can handle the thickness/width of stock you plan to cut.

Double Check Thickness Cutting Capacities - Punch
Trying to cut too thick in to wide of stock can lead to tool damage and a large repair bill. Always check
the machine or insert tool can handle the thickness/width of stock you plan to cut.
Punching Capacities
You can determine the tonnage required to punch A36 mild steel (yield
strength 36,300 psi, 65,000 psi tensile) by applying the following formulas for round or shaped holes. For
materials other than mild steel
please refer to the multiplier table.
Round Holes
Punch Dia. x Material Thickness x 80 = Tons of pressure required
Example: How many tons of force do I need to punch a
3/8” hole in 1/4” mild steel?
.375 x .25 x 80 = 7.5 tons
Material Multiplier
When punching materials other than mild steel first calculate
tonnage as shown above then apply the multiplier for the listed
material.

Secure stock with material clamp/guards
Depending on which function you plan on using you will need to make sure the guard and or material
clamp is set properly.
1. Angle Shear
When you slide your stock through the v groove make sure once in place to tighten the handle to
lock your stock down. This will prevent your stock from lifting possibly miss cutting your stock.
2. Flat Shear
Once your material is in position to cut tighten the material clamp down on your stock so it that it
wont lift while being sheared.
3. Notcher
Always use the guard/guide while using the shear. This is a safety device and should not be removed.
4. Hole Punch
Always use the guard while operating the hole punch, it is a safety device and should always be
present. Additionally it acts as a stripping plate to help release your material after holes are puched.

Installing the proper punch
Improper Installation of a punch can cause costly tool damage
1. Always turn E stop the machine before changing tooling
2. Using the large wrench provided, lift the guard by loosening the 4 bolts (2 on either side) holding
it in place
3. Again with the large wrench loosen the nut holding the punch in place
4. With an allen wrench loosen the die in the base
5. Replace die and punch with desired sets
6. Check for punch and die alignment by powering up the machine
and inching down the punch to meet the die with the foot pedal.
Check to see that the punch is centered in the die.
7. If the punch and die are not aligned, loosen the
bolts under the table allowing the table to be moved to center the
die. When aligned, tighten the table bolts to secure the table
Punch and Die Operating
Clearances
