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™ Siding 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 Magnum™ Siding
Shear 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.
