Elements and Performance Criteria

1. Identify performance requirements for servicing
   • Features and performance characteristics of micro-mechanism are identified.
   • Performance problems common to make and model are identified.
   • Performance requirements for given task are identified and clarified with appropriate persons.
2. Diagnose faults and servicing requirements
   • Overall condition of micro-mechanism is assessed.
   • Physical condition and operational functioning of components inspected and verified, if necessary, with appropriate persons.
   • Servicing requirements are established with appropriate persons.
   • Performance problems are diagnosed and verified, if necessary, with appropriate persons.
   • Replacement parts are sourced according to enterprise procedures.
3. Service micro-mechanisms
   • Components are dismantled and cleaned to specification.
   • Requirements for new components are identified.
   • Components are refinished/replaced as required.
   • Components are assembled and lubricated to specification.
   • Components finished and adjusted to specification.

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to diagnose and service micromechanisms Competency in this unit cannot be claimed until all prerequisites have been satisfied
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria including required knowledge and be capable of applying the competency in new and different situations and contexts
Context of and specific resources for assessment	This unit may be assessed on the job off the job or a combination of both on and off the job Where assessment occurs off the job that is the candidate is not in productive work then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team The assessment environment should not disadvantage the candidate This unit could be assessed in conjunction with any other units addressing the safety quality communication materials handling recording and reporting associated with diagnosing and servicing micromechanisms or other units requiring the exercise of the skills and knowledge covered by this unit
Method of assessment	Assessors should gather a range of evidence that is valid sufficient current and authentic Evidence can be gathered through a variety of ways including direct observation supervisors reports project work samples and questioning Questioning techniques should not require language literacy and numeracy skills beyond those required in this unit of competency The candidate must have access to all tools equipment materials and documentation required The candidate must be permitted to refer to any relevant workplace procedures product and manufacturing specifications codes standards manuals and reference materials

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Micro-mechanisms	Mechanical and electric watches and clocks of recent manufacture, or restoration pieces. May include day/date, automatic winding or generating systems. Clock mechanisms may include alarm, striking and chiming mechanisms
Components	Power source, wheel trains, mechanical oscillating systems, motion work and calendar systems
Inspection	Observations of clearances, fits and adjustments, functioning. Operation of systems and performance analysis
Appropriate persons	Customers, supervisors/managers/suppliers, technical experts, colleagues
Specifications	Manufacturer specifications. Recognition of components of product and how quality of component and materials will affect performance
