6.2 BAR SHEAR OPERATION
⌦
CAUTION: ANY TIME THAT THE SHEAR SECTION IS NOT IN USE, CRANK THE HOLD-
DOWN DEVICE TO ITS FULL DOWN POSITION.
Before using the bar shear, make sure that all tooling has been moved out from under the upper arm and
that the punch and die have been removed from the punch station. When using the Bar Shear on your
Scotchman Ironworker, ALWAYS use the hold-down device.
NEVER put any part of your body between the hold-down and the material to be sheared.
A clearance of 1/8 inch (3mm) between the hold-down and material to be sheared is acceptable.
The maximum tonnage available on the bar shear is to the left, or closest to the pivot point. For
applications that do not require the maximum tonnage, move the material to the right, for minimal
distortion on the drop piece.
Do not attempt to shear pieces that are too short for the hold-down to grip as this will cause the material
to kick-up and will result in a poor quality cut and possible damage to the machine.
THE BASIC METHOD OF OPERATING THE BAR SHEAR CONSISTS OF SIX STEPS:
1. Place the selector switch in the START position and power the machine.
2. Place the selector switch in the SHEAR position.
3. Place the material to be sheared between the shear blades.
4. Crank the hold-down device down to the material being sheared. This prevents kick-up of the
material, which could cause injury to the operator and damage to the machine.
5. Keep your hands clear from all moving parts.
6. Depress the foot switch. Lubricate the blades every 10 to 15 cuts.
