The Gutter’s Hem / Lip Is Too Small

Category: Seamless Gutter Machines

If the hem or lip on your finished gutter is coming out too small, less than the minimum recommended 1/4″, it could hinder the way the gutter functions or cause it to be improperly installed. Having too small of a lip can also cause the gutter to run uphill and into the building.

On a MACH II™ Gutter Machine, the easiest way to fix the problem is to move the Face/Right Entry, Back/Left Entry, and Post Entry Guides to the right. (Note: “left” and “right” sides refer to when you are facing the entry end of the machine.) Reference the Entry Guide Assembly Section of your manual for instructions based on the sizing and configuration of your gutter machine.

  1. To fix this issue, move the Face/Right, Back/Left Entry Guide, and Post Guide to the right.
  2. The Face/Right Entry Guide controls the amount of material that is fed into the face roller and box assembly. It should be moved only to increase or decrease the amount of lip that is turned under.
  3. If an adjustment is made on the Face/Right Entry Guide, an adjustment must be made on the Post Guide on the first skate assembly as well as the Back/Left Entry Guide, using the coil as a guide. There should be no visible space between the entry guides and the coil. The guides should also not be so tight as to cause the gutter material to bind in the entry guide assembly.

***Depending on the year your machine was manufactured, there are some differences in the parts that need to be adjusted:

  • If your machine was machine manufactured in December 2014 or EARLIER: The last 4 digits of your machine’s serial number will give you the month and year it was produced. If the last 4 digits are 1214 (December 2014) or earlier, you will not have the Post Entry Guides to move.
  • If your machine was manufactured in January 2015 or LATER: If these 4 digits are 0115 (January 2015) or later, you will have a Post Guide Assembly.
