This section provides links to the required adjustments of the trimmer drive assembly and its related components. These links are numbered in an order intended to provide for the best success in making adjustments to this area of the machine. All of the trimmer replacement procedures are located in the Lower Bed Assembly folder under Service and Repair->Embroidery Head.
The AMAYA Embroidery Peripheral trimmer system is assembled and thoroughly tested before the machine is shipped. Although the setup of the trimmers should not change during normal use, there are a few things to be aware of to prevent problems:
Dirt, dust and thread lint can build up and prevent the moveable knife (in the rotary hook assembly) from actuating correctly. Keep this area clean and you should not have a problem here. If for some reason you should find the moveable knife is out of adjustment, an adjustment procedure is available.
Thread birdnesting around the rotary hook area could knock the knife out of adjustment.
The following procedures provide a guide for adjusting various portions of the trimmer assembly.

These procedures require the use of several service tools: a medium screw driver, a small screw driver, a 3/32" hex wrench, a 1.5mm key wrench, a 2mm key wrench, and a 2.5mm key wrench. In addition to the "standard" tools needed above, you will need a torque wrench (0-250 in/lbs) if making adjustments to the "select" position.

CAUTION!! If these adjustments are attempted without using the proper procedures and tools (and without proper training in some cases), machine components may become damaged and operation of the trimmers may become inconsistent. |
An area of concern with the trimmer system is birdnesting in the hook area. If this occurs, there is the potential that the moveable knife movement may be obstructed, and mechanical slippage or bending may occur with one or more components in the trimmer system. This is the most probable cause for the trimmer system to create Z-axis related machine errors. When Z-axis related machine errors are the result of the trimmer system, there are three general areas that may contribute to the situation: 1) bent or broken parts in the trimmer drive system, 2) moveable knife select position adjustment, and 3) loose or broken trimmer home sensor.
Check for and adjust damaged components in the following order (click on the link for the procedure):

CAUTION!! Before executing any Head Up command in the following procedures, verify that the moveable knife is clear of sewing "needle bar stroke" area. |
When all of the above procedures have been completed, install all of the covers and the needle plate that were removed to complete the above procedures.
