MAINTENANCE
Check the condition of this tool every time before using it.
1. Before each use, plug in the tool, and turn it on to run freely for one minute.
2. A f t e r the toofl has run for one mfinute, turn fit off, and put 3
-4 drops
of light machine oil in the oil port on the head of
the tool.
(See picture at right.)
3. Also apply a small amount of oil into the space between the
Arbor (13) and the Shaft Sleeve (15).
To remove or replace the blades:
1. Unplug this tool before attempting any maintenance.
2. Remove the Screw and Washers (6,5,4) holding the Upper
Shear Blade (12) & remove it as shown in the photo below
left, using the included Hex Key.
3. Remove the Screw and Washers (6,5,4) holding the Lower Shear Blade
(12) & remove it as in photo below right.
4. 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.
5. The Upper Shear Blade (12) has a Adjusting Screw (8) and 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 (8) can be adjusted. The Upper Shear Blade (12) should be
adjusted for different material
types or thicknesses.
For sheet steel the formula is:
Gap = Steel Thickness / 5
(as discussed in item 3, page 7)
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).
6. Check that the blades will operate properly before use. The machine should always be tested on scrap
material before use on final work material.
7. If you sharpen the blades, maintain the original dimensions of a 12 degree angle on the Upper Shear
Blade (12) with a 8 degree angle across its thickness. Maintain a 4 degree angle on the butt of the
Lower Shear Blade (2) as shown in the illustration below.
