MAINTENANCE
FLAT SIDE OF BLADE
HONING
STONE
Honing the Blade
Push the handle down until the blade 1/8" (3mm) above the
tabletop. Place the provided Hone Stone against the flat
side of the blade. Slide the honing stone from one end of
the blade to the other 3-4 times. This will remove any burrs
from your blade.
When you first get your shear, you should hone after your
5th cut, then hone your blade every 10th cut for the first
100 cuts until your blade is broken in. From there, you only
need to hone once per job. Use caution when honing the
blade. The blade is sharp and can easily cause injury. Cut
resistant gloves are recommended when honing the blade.
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.
Greasing/Lubricating
Regularly lubricate your shear (every few hundred cuts or
once per job). Use a light oil (e.g. 10W motor oil or WD-40)
to lubricate the sliding contact faces where indicated. Use
grease (e.g. automotive bearing grease) to lubricate the
inside of the bearings. Wipe off any excess.

Sharpening the Blade
The blade can be sharpened to restore a one-sided, 21° – 22° 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 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 do not remove) the screws. Adjust the jack screws to desired
position with 5/32" or 4mm Allen wrench.
