fasten some dimensional lumber in place as ‘spacers’
before attaching your shear.

BACKSTROKE STOP
The blade should be set so it cuts into the plastic blade stop (F) when the
handle is pressed down.
To open the blade to cut materials over ⁄" (19mm) thick, loosen Phillips head
screw on the Backstroke Stop (D); turn the Backstroke Stop 180º and tighten
screw. For more convenience when cutting thinner products, restore factory
setting.
CUTTING DEPTH
You may need to adjust the height of the blade to cut all the way through your
product. You can do this by adjusting the stop screw.
ADJUSTING THE STOP SCREW
1. Loosen the stop screw nut (E) and turn stop screw until it is loose. Release
handle to open blade.
2. Push the handle down until the blade is resting on the blade stop (F)
3. Adjust the stop screw until it makes contact with the power assembly.
TRANSPORT
It is important to re-engage lock and secure unextended handle in down
position while storing, carrying, or transporting your Magnum Siding Shear.
TIP: DOUBLE CUTTING
Most materials shear very well with just one cut. However, some brands may
require cutting twice to produce a better cut.
Simply make your first cut ⁄" to ⁄" (3 to 6mm) longer than your mark, then
go back and make your second cut on your mark. This is very useful to create
a cleaner cut when a trim molding or transition cannot be used to cover your
cut end.
ADJUSTMENTS
THE ANVIL
The anvil has two edges: a ⁄" (0.75mm) narrow edge
and a ⁄" (4.5mm) wide edge. Either edge can be used
according to the support needed to make a clean cut.
Some soft-backed products require the wider anvil
edge.
TO CHANGE BETWEEN ANVIL EDGES
Simply remove the anvil screws and flip the anvil over.
Ensure blade stop is in place.

MAINTENANCE
FLAT SIDE OF BLADE
HONING
STONE
Honing the Blade
Push the handle down until the blade ⁄" (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.
For more information on honing your blade,
follow this QR Code link or URL below:
https://marshalltown.com/honing-your-blade
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 ⁄" or 4mm Allen wrench.

TROUBLESHOOTING
Before troubleshooting double-check the manual:
• Is your shear properly assembled?
• Is it being operated correctly?
• Is it properly lubricated?
• Has the blade been honed as recommended?
Visually inspect shear, watching for objects that might obstruct the blade or powerhead travel:
• Foreign material presence between the blade and anvil, in the pin springs or under the cam.
• Check your blade for chips, cracks or burrs.
• Make sure bearings are intact and lubricated. They should not be spinning/moving on the cam during use.
NOTE: This troubleshooting is for all Bullet shears. If you are uncertain if it pertains to your shear, please contact
Marshalltown customer service.
