MAINTENANCE
Greasing / Lubricating
After every 100 cuts, lubricate the wear points of the
pins and the bearings as shown. Use a light oil (i.e. 10W
motor oil). This will prevent the machine from wearing
out prematurely. Apply grease (wheel bearing grease)
frequently to the bearings where indicated.

Honing the Blade
Hone every 100 cuts
Push the handle down until blade is 1/4” (6mm) open.
Lay the hone stone against the flat face of the blade
(side toward the table). Slide from end to end 2 or 3
times.
Adjusting the Blade
Your shear is equipped with adjustment "jack"
screws for fine tuning the angle of your blade or
compensating for small blades (Blades get smaller
every time they are re-sharpened). To tilt your
blade, turn the machine upside down - loosen
(but don't remove) the blade screws. Adjust the
jack screws to desired position with 5/32" or 4mm
Allen wrench.

Sharpening the blade
The blade can be sharpened to restore a one-side, 21º - 22º knife edge. It is important to note that the blade
must be sharpened only on the beveled side, leaving the flat side flat.

We recommend that power grinding only be done professionally, as the blade must be fluid cooled during this process.
The Blade Stop
The blade stop may become worn. Remove anvil, turn blade stop over for more use. Replacements can be
purchased at your dealer.
