Please make sure that the handle is parallel to the blade when tapping and pay attention to the strength and position of the tapping to avoid damage to the handle. How To Operate This Paper Cutter Correctly? 1. Determine the desired paper size that needs to be cut and move the positioning block to the target scale on the surface. 2. Open the movable blade from the right side and remove it from the safety lock. 3. Push the paper towards the left to the black positioning block and confirm that the paper is placed accurately. 4.

Common Problems(Q&A): 1. Why is the blade not straight? The curvature is to increase the friction of the two blades to achieve the effect of cutting paper. In fact, curvature exists not only in fixed blades, but also in movable blades, which is essential for manufacturing. However the curvature is not standardized and each brands might have different designs. 2. Why are the papers I cut with the paper cutter is not straight? We promise that each tool is allowed to be sold after being tested in the factory. Generally speaking,8-10 sheets of 70GSM paper are easy to cut. Please remember to press the paper with your left hand, grab the handle with your right hand and pushing the blade slightly to the left to close to the paper cutter at the same time. Beginners may need to practice several times. 3. How to use the magnetic positioning block? This block can be used as a positioning block when cutting. You can place it on the operation panel as you wish, as long as it is aligned with the scale. If you have mastered the cutting method, you can choose to ignore it. Note: the block is not used to press and fix the papers to make the papers not move. You still need to press the papers with your hand. 4. How to align the paper? You need to align the upper aluminum bar (the one with the logo), and the side alignment is to align the scale on the surface or the right edge line of the base. 5. How many sheets of paper can be cut at one time? We recommend to cut less than 10 sheets at a time. Generally speaking, 8-10 sheets of 70G5M paper are easy to cut. In fact, the thickness of the paper also needs to be considered. If the paper is too thick or too hard, it may get stuck and cannot be cut. Using more than the recommended amount of paper could cause permanent damage to the blade. 6. Cleaning and Maintenance: After cutting the sticky paper, please remove the glue or sticky material on the blade, otherwise it will affect the sharpness of the cutter after long term use and may making cutting not straight. lf the knife becomes dull after a period of use, you can use a flat file to grind the 4 flat surfaces on both sides of the blade back and forth. Be careful not to damage the cutting edge when grinding.
