The Gutter’s Hem / Lip Is Too Big

If the lip or hem of the gutter is coming out rippled or distorted, it may be too big. The recommended lip on a gutter is approximately 1/4″ to 5/16″ maximum, turned under.

On a MACH II™ Gutter Machine, the easiest fix is to move the Face/Right Entry, Back/Left Entry, and Post Entry Guides to the left. (“Left” and “right” refer to facing the entry end of the machine.) Reference the Entry Guide Assembly section of your manual for instructions based on your machine’s sizing and configuration.

If you adjust the Face/Right Entry Guide, you must also adjust the Post Guide on the first skate assembly and the Back/Left Entry Guide, using the coil as a guide. There should be no visible space between the entry guides and the coil — but not so tight that the material binds in the entry guide assembly.

Manufacturing-date considerations

• December 2014 or earlier: If the last 4 digits of your serial number are 1214 or earlier, you will not have Post Entry Guides to move.
• January 2015 or later: If the last 4 digits are 0115 or later, you have a Post Guide Assembly.
