Setup:
Place the paper trimmer on a stable and flat surface, ensuring the anti-slip rubber base is in contact with the tabletop.
Verify that the cutting and scoring blades are securely in place.

Measuring:
Use the ruler or scale on the trimmer to measure and mark the desired length of your material.

Placement:
Lay your material (such as cardstock, EVA foam, or photographs) on the trimmer's base, aligning it with the marked measurement.

Alignment:
For precise cuts, make sure the material is aligned with the cutting guide. The scale extender and alignment guide can assist in repetitive cutting.

Cutting:
If you're cutting, use the cutting blade. Slide the blade carriage down the rail to the starting point, then smoothly slide it up along the material, applying steady and even pressure.

Scoring:
If you're scoring, switch to the scoring blade. Follow the same process, applying gentle pressure to create a score line without cutting through the material.

Scale Extender:
Utilize the scale extender for larger projects, ensuring accurate measurements across the extended length.

Blade Replacement:
When it's time to change the blade, slide the blade carriage down the rail to the removal groove. As it nears the groove, pull it up, and the blade easily comes out. Insert the new carriage into the groove, slide it up the rail, and you're ready to continue cutting.

Choose the Right Blade, Measure Twice, Cut Once, Use the Alignment Guides, Apply Even Pressure
