Some states do not allow limitations on how long an implied warranty lasts or the exclusion or limitations of incidental or consequential damages, so the above limitations or exclusions may not apply to you.

PRODUCT OPERATION

Note: Every 1″ of width requires approximately 40lb (18kg) on the handle. (e.g. a 4″ wide plank requires 160lb (72kg) to cut, 5″ wide plank requires 200lb (90kg) to cut.)

MAKING CUTS
The Magnum Edge Hardwood Shear is operated manually. The two-part extendable handle is grasped by the operator and pushed down to make a cut.
CUTTING

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

ADJUSTMENTS The blade should be set so it cuts into the plastic blade stop (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 1/4 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.

Please note: 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 before proceeding. The warranty is void if an unapproved product damages the machine.
45 DEGREE CUTS
Firmly lift the friction-fit fence to remove it from the table and press back down in the appropriate 45-degree position. NOTE: This image is for the Marksman. Your shear may look slightly different.

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. (Shown Right)
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.
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.
TIP:
If the groove of your planks splits when cutting, rip a scrap piece and place it alongside as support.

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.

MAINTENANCE

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.
For more information on honing your blade, scan the QR code or visit www.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 powder grinding only be done professionally, as the blade must be fluid cooled during this process.

TIGHTEN THE SCREWS
With regular use, several of the screws on this shear can sometimes become loose. Regularly check tightness on all screws, especially those connecting the handle. They should be turned in until they stop then torqued an extra 1/4 extra turn. Use 4mm or 5mm hex key, as appropriate.
CHANGING THE BLADE
Required tools: 5/32″ or 4mm hex key “Allen” wrench
WARNING
USE EXTREME CAUTION! The blade is very sharp.

1. TURN THE SHEAR UPSIDE DOWN
   Tip: put the shear on the edge of a sturdy table.

2. LOOSEN THE BLADE
   Using a 5/32″ or 4mm hex key “Allen” wrench, remove the Button Head Socket Cap Screws screws.

3. REMOVE BLADE
   Hold blade by each end and carefully lift out of pocket.

4. 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 the pocket is clear of debris.

5. TIGHTEN THE BLADE
   Using a 5/32″ or 4mm hex key “Allen” wrench, replace and tighten the screws, starting with the center screw.

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 key “Allen” wrench
– Fill the grease cavity with grease
– Re-attach the end cap
– Repeat the 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.

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.

PROBLEM CHECK FIRST CHECK SECOND CHECK THIRD CHECK FOURTH

PROBLEM| CHECK FIRST| CHECK SECOND| CHECK THIRD| CHECK FOURTH
---|---|---|---|---
__ Difficulty cutting| Ensure the cam lock is OFF. If

equipped, engage power lobes (Model 226)

| Make sure the handle is FULLY extended| Check blade sharpness/ condition| Inspect and lubricate bearings/pins
Not cutting completely through the material| Inspect pins for oblong/wallowed orifice| Adjust front stroke stop (MAGNUM shears)| Check bearings for wear/play| Ensure the blade is proper nominal height
Blade sticking after completing cuts| Check/remove & replace blade stops if damaged| Ensure blade screws are tight| Remove the anvil, turn it over, reinstall| Check for marks on the anvil (overbite)
Rough or crushed cuts| Check veneer thickness (max= 1/16″)| Check blade condition (chips, burrs, breaks)| Ensure the blade is honed and sharp| Review approved materials list
Cuts aren’t square| Loosen fence screws, align fence, tighten| Check pins for uneven wear| Inspect blade and anvil/blade-stop for contact|
Handle not returning to open position| Ensure pins are lubricated| Apply grease to the contact area of bearing| Lubricate axle bolts| Check springs for breakage
 The material won’t fit into the cut area| Check the max thickness of material for your shear| Reverse backstroke stop| Ensure the blade is proper nominal height| If you have two bearings, switch which bearing is engaged
Cam lock pin bent/stuck| Do not lift or carry shear by the handle| Return handle slowly to open position – do not “let it fly”| Disengage cam lock pin BEFORE cutting|
Blade chipping| Hone as directed in the manual (~25 cuts, then daily)| Do not cut stranded bamboo| Do not cut high-pressure laminate| Check veneer thickness (max=1/16″)
Pin openings wallowed out / oblong where cam axle passes through| Do not lift or carry shear by the handle| Return handle slowly to open position – do not “let it fly”| Check veneer thickness (max= 1/16″)| __

Review approved materials list

Not cutting to edge of the material| Check fence alignment – adjust if needed| __ Do not “angle” material beyond the blade edge| Ensure angle fence(s) are installed with WIDE edge inward (620 models)|
