After Each Use
⚠WARNING
Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the
hands of untrained users.
Do not touch the metal shear right after use.
Replacing the Blades
1. Remove the screw and washer (6, 5, 4) holding the upper shear blade (reference area 12) and
remove it as shown in the image below, using the included hex key.
2. Remove the screw and washer (6, 5, 4) holding the lower shear blade (reference area 2) and
remove it as in image below.
3. To reinstall sharpened blades or new blades, first reinstall the lower shear blade (2) and tighten it.
Then install the upper shear blade (12) but leave it just loose enough to slide.
4. The upper shear blade (12) has an adjusting screw (8) and second screw (6) that are used to
adjust the blade’s position. The screw (6) should be loosened with a wrench. Then the lock nut (7)
should be loosened and held using a box-end wrench (not included) and the adjusting screw can be
adjusted. The upper shear blade (12) should be adjusted for different material types or thicknesses.
Adjusting the Upper Shear Blade (12)
For sheet steel the formula is: Gap = steel thickness divided by 5.
The gap will be slightly smaller for rubbery or soft materials. The gap should be slightly larger for hard
materials.
When the two blades line up with the proper gap, tighten and hold the adjusting screw (8) while you
tighten the lock nut (7). Then, tighten the screw (6).
5. Check that the blades will operate properly before use. The machine should always be tested on
scrap material before use on final work material.
6. If you sharpen the blades, maintain the original dimensions of a 12° angle on the upper shear blade
(12) with an 8° angle across its thickness. Maintain a 4° angle on the butt of the lower shear blade (2)
as shown in the illustration on the following page.
