7000E Squaring The Paper Guide Rail
Warning: The 7000E contains an extremely sharp blade. Martin Yale recommends that all instructions are reviewed before beginning this procedure. If you have any questions, or would like to be referred to an authorized service technician, Customer Service can be reached at 800-225-5644.
Note: Before performing this procedure, check the obvious.
- Make sure the sheets being cut are square before using.
- Make sure the Pal Nut on the Backguage adjustment screw is in place. See photo at right.
- Make sure that sufficient clamping pressure is being used to hold the material Stationary (1/4 turn past snug), and that the blade is sharp (1,000 cuts between sharpenings for Bond paper)
Phillips Screw Driver Rubber Mallot (Or Comparable Alternative) T-Square or Right Angle Wedge
In order to cut squarely, the paper guide rail must be at a 90° angle to the blade. This is accomplished by loosening the (3) Phillips screws that hold the paper guide rail (ruler on top) in place, lowering the blade to the ‘down’ position, and verifying the degree of angle is correct. Should it need to be corrected, tapping the guide rail with a rubber mallet (while screws are loose) until the proper degree of angle is achieved is ideal.
The circled area denotes the intersect point at which there must be a 90 degree angle.
The paper guide rail (square area) must be at a 90 degree angle to the blade

Quick start
- Check the obvious first: sheets are square, the Pal Nut on the backgauge adjustment screw is in place, clamp pressure is 1/4 turn past snug, and the blade is sharp.
- Gather a Phillips screwdriver, a rubber mallet (or similar) and a T-square or right angle wedge.
- Loosen the three Phillips screws that hold the paper guide rail (ruler on top).
- Lower the blade to the down position and check the rail is at 90° to the blade.
- If needed, tap the guide rail with the rubber mallet until it is square, then retighten the screws.
Troubleshooting
| Problem | Likely cause | Fix (from the manual) |
|---|---|---|
| Cuts are not square | Paper guide rail is not at a 90 deg angle to the blade | Loosen the three Phillips screws, lower the blade, and tap the rail square with a rubber mallet before retightening. Page 2 |
| Material shifts or cuts poorly | Insufficient clamping pressure or a dull blade | Clamp 1/4 turn past snug and keep the blade sharp (about 1,000 cuts between sharpenings for bond paper). Page 2 |
Frequently asked questions
How often should the 7000E blade be sharpened?
About every 1,000 cuts for bond paper (page 2).
How tight should the clamp be?
1/4 turn past snug, enough to hold the material stationary (page 2).
What tools do I need to square the guide rail?
A Phillips screwdriver, a rubber mallet or similar, and a T-square or right angle wedge (page 2).
