SETUP

INSTALL MOUNTING BRACKETS AND ATTACH THEM TO THE CUT STATION OR STAND
Using a T30 bit (included) and socket or screwdriver, unscrew four lower rail attachment bolts 1/4″ (6mm). Slip mounting brackets up over rail attachment bolts and tighten securely. Fasten to chop-saw stand or cut station using appropriate hardware such as 5/16″ diameter bolts or lag-screws and corresponding washers (not included).
When using a bench-type cut station, it is convenient to fasten some dimensional lumber in place as ‘spacers’ before attaching your shear.

PRODUCT OPERATION

CAUTION
BLADE IS VERY SHARP – USE EXTREME CAUTION

MAKING CUTS
The Magnum Edge Siding Shear is operated manually. The two-part extendable handle is grasped by the operator and pushed down to make a cut. A SIDING BLADE IS PRE-INSTALLED IN THIS SHEAR, DO NOT USE IT TO CUT HARDWOOD.

To unlock, gently press the handle down, and slide Cam-Lock (A) in and down.
Place material (B) on the table, and slide under the blade to desired cut position.
Push handle (C) down until material is completely cut.

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 1/8″ to 1/4″ (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

NOTICE
DO NOT CUT HARDWOOD WITH THIS SHEAR!

DEPTH ADJUSTMENTS
The blade should be set so it cuts into the plastic blade top (D) when the handle is pressed down.
To set the blade depth, rotate the two large nuts (E) on the underside of the base with an 11/2″ (38mm) wrench.
Ensure that both are turned an equal amount.
Adjust in quarter-turn increments and check to see how deep the blade is set.
To open the blade to cut 1″ material, loosen the Back Stop Knob (F) and rotate the Back Stop (G) up.

THE ANVIL
The anvil has two edges: a 1/32″ (0.75mm) narrow edge and a 3/16″ (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.

NOTICE
Approved materials may vary in density and hardness. If extreme pressure is required to cut a product, it may result in damage to your machine. Please contact MARSHALLTOWN Tools before proceeding.
The warranty is void if an unapproved product damages the machine.

SAFETY LOCK
For maximum security, the safety lock will automatically reset in the “locked” position unless disengaged. The safety lock can be disengaged by sliding the knob over and down and hooking it into the slot.

TRANSPORT
It is important to re-engage the lock and secure the unextended handle in the down position while storing, carrying, or transporting your Magnum Edge Flooring Shear.

MAINTENANCE

LUBRICATING
Your Magnum EDGE has been pre-lubricated with grease under the end caps. Re- Grease every 2 years of use, or if the shear starts squeaking.

Lock the handle down
Lay your Magnum EDGE on its side
Remove the end cap by unscrewing the two button head screws with a 5mm hex “Allen” wrench
Fill the grease cavity (H) with grease
Re-attach the end cap
Repeat procedure on the other side

THE BLADE STOP
The blade stop may become worn. Remove anvil, turn blade stopover for more use. Replacements can be purchased at your dealer.

For more information on honing your blade, follow this QR Code link or URL below:

https://marshalltown.com/honing-your-blade

HONING THE BLADE
Push the handle down until the blade is 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.

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.

REPLACING THE BLADE

TURN SHEAR UPSIDE DOWN
Tip: put the shear on the edge of a sturdy table.
LOOSEN BLADE (I)
Using a 5/32″ (4mm) hex key “Allen” wrench, remove the Button Head Socket Cap Screws screws (J).
REMOVE BLADE
Hold blade by each end and carefully lift out of pocket
INSTALL BLADE
Hold the blade by each end and carefully place it into the blade pocket in the head, with the flat side of the blade facing the table. Be sure that it is firmly seated, and that the pocket is clear of debris.
TIGHTEN THE BLADE
Using a 5/32″ (4mm) hex key “Allen” wrench, replace & tighten the screws, starting with the center screw.

WARNING
USE EXTREME CAUTION! The blade is very sharp.

TROUBLESHOOTING

Before troubleshooting double-checks 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 is present 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.
