Frequently Asked Questions - KN 14 GUDE

What type of staples to use for the KN 14?

Use type 14 staples, 6 mm wide and 4-14 mm long. These staples are commonly available in stores.

How to load staples into the stapler?

Open the magazine by sliding the cover backwards. Insert the staple strip with the points down. Close the magazine until it clicks.

Can the stapler staple into hardwood?

Yes, but manual power may be limited. For hardwoods, use shorter staples and press firmly. For heavy-duty applications, prefer a pneumatic stapler.

How to adjust the stapling depth?

Most KN 14 models have an adjustment knob on the side. Turn it to adjust the driving force and thus the staple depth in the material.

What to do if the stapler jams?

Unlock the safety trigger. Open the magazine and remove the staple strip. Use pliers to manually remove the stuck staple. Then lubricate the mechanism.

Is the KN 14 stapler suitable for upholstery work?

Yes, it is perfectly suitable for attaching light fabrics, canvas, or plastic films to wooden frames. Use 6 to 8 mm staples for optimal results.

How to maintain the stapler to make it last long?

After each use, clean it with a dry cloth. Oil the moving parts with a drop of machine oil. Store it in a dry place. Avoid drops.

Is the warranty included?

Yes, Güde offers a 2-year warranty on manufacturing defects. Keep the invoice and manual for any claims.

Can I use staples from other brands?

Yes, as long as they are type 14 and meet the dimensions (width 6 mm, length 4-14 mm). Generic staples usually work well.

What to do if the stapler does not drive staples fully?

Check that the staples are properly loaded and of the correct type. Adjust the stapling depth. If the problem persists, lubricate the mechanism or replace the impact spring.
