When to hone
There are three situations when it is very important
to hone the blade (remove burrs) on the flat side of
the blade.
1. After the first 30-100 cuts on a new blade
2. Every 100+ cuts on the job
3. When the blade has been re-sharpened
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.
adjusting the Blade
Your Magnum™ Flooring Shear is equipped with adjustment "jack" screws (see pic on next page) for
fine tuning the angle of your blade or compensating for small blades (Blades shrink every time they
are re-sharpened). To tilt your blade, turn the machine upside down as when removing the blade -
loosen (but don't remove) the Item D screws. Adjust the jack screws to desired position with 5/32" or
4mm Allen wrench.
to hone
With the blade in the machine, it is quick and
easy to hone; Simply pull the handle down
until the blade is just above the blade stop
(approximately 1/8"). Then, lay the wide flat side
of the hone stone against the flat side of the
blade and move hone stone from end to end 2
to 3 times to remove any burrs.
Use Hand Protection! Blade is very sharp!
Note: It is not necessary to remove the small nicks or chips from
the blade edge when sharpening or honing.
