2. Service Adjustments
General
This section of the manual provides detailed information for performing machine
adjustments required during maintenance or parts replacement. The procedures are
guidelines for performing service maintenance, and must be used by personnel
practicing good maintenance technique. Good maintenance technique includes,
but is not limited to, adhering to all precautions and safety considerations when
working on the unit; and using the correct tools for the job being performed.
It is recommended that some procedures in this section be performed by factory
trained personnel to obtain best results. This reference is indicated by stating
"FACTORY SERVICE ADVISED" at the start of the procedure.
Drive Belt Tensions
"FACTORY SERVICE ADVISED"
CAUTION! Damage to the machine may result if belt tensions are improperly
performed.
All drive belts require special procedures and tools for setting the proper tensions. If
the tension settings are attempted without using the proper procedures and tools
(and without proper training in some cases), machine components may be
damaged. If a belt tension adjustment is needed, follow the procedure in the
manual or, if "factory service is advised," contact your local factory trained service
representative.
Physical/Functional Identification
As discussed in Section 1 of this manual, the EMC 10/4 is functionally and/or
physically arranged into several sections. This section of the manual is laid out in
accordance to those machine areas. To identify these areas refer to Section 1 of the
manual.
Controller Section
The controller section is so named because of its many controlling functions.
Located within the controller section is the CPU PCB. the CPU processes data and
translates instructions that are input to the unit by the operator. The Trimmer
Interface PCB is also located in the controller section. This PCB helps to interpret
data relating to such things as color change, embroidery speed, and trimmer timing
(with trimmer option).
Although no adjustments are performed inside the controller section of the EMC
10/4, there are occasions when reference is directed to this section to monitor or
measure the results of other adjustments.
