Elements and Performance Criteria

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.
Function and type of striking mechanism
Function and type of striking mechanism may include:
motive force (e.g. mainspring or weight driven )
gear train (e.g. transmits power)
ways of producing striking sound (e.g. metal gongs, chime rods, bells and air bellows)
count wheel striking movements (e.g. European and American manufacture)
rack striking movements (e.g. European and American manufacture )
Record and document repair process
Record and document repair process may include:
date and extent of repair
cost of replacement parts
time spent on procedure
Operation of strike mechanism
Operation of strike mechanism may include:
hour struck corresponds with hands
release mechanism synchronised with hands
warning set-up correctly
function of release mechanism
sound generation (e.g. gongs, rods and hammer engagement)
Striking mechanism components
Striking mechanism components may include:
release mechanism
gathering pallet
detents
counting mechanism (e.g. snail and count wheel)
rack
gongs, chime rods and bells
hammers
Faults in striking mechanismcomponents
Faults in striking mechanism components may include:
incorrect striking
continuous striking
striking mechanism stops clock or impacts on timekeeping
warning set-up
gong security
pin security
gathering pallet engagement with rack teeth, tightness and positioning
rack tail engagement position with snail
hammer inserts (e.g. condition - worn or aged)
security of gongs, rods and attachment to case
Correct set-up
Correct set-up may include:
synchronised strike release with hands
amount of warning
correct sequence
sound of strike
Lubricants to striking mechanismcomponents
Lubricants to striking mechanism components may include:
correct lubricants for cams and detents
techniques for lubricating
Hand and bench tools and equipment
Hand and bench tools and equipment may include:
clock repairers' hand tools (e.g. tweezers, screwdrivers and eyeglass)
universal shifter, sockets and spanners
pliers, end cutters and files
stakes for supporting removal or replacement of gathering pallet and cannon pinions
oilers and oil pots and greases
hand cleaning (e.g. pith, peg wood and rodico solvents jar)
Appropriate working environment
Appropriate working environment may include:
clean bench and working area
adequate lighting and ventilation
tools and equipment organised and in good condition
ergonomic seating, including bench height
Clean and safe work environment
Clean and safe work environment may be specified through:
relevant legislation and regulations
enterprise operating procedures
5S housekeeping related principles and procedures (e.g. sort, straighten, shine, standardise, sustain)

EVIDENCE GUIDE
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 service and repair clock striking mechanisms to industry standards, manufacturer specifications and in accordance with safety regulations and procedures.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Assessors must be satisfied that the candidate can competently and consistently:
dismantle and reassemble clocks with count wheel striking mechanisms
dismantle and reassemble clocks with rack striking mechanisms
perform operation and performance testing of striking clocks
adjust striking clock mechanisms for correct operation and synchronisation with hands and sound generation and tonality
apply lubrication techniques (e.g. correct type and amount)
diagnose faults relating to strike mechanisms.
Context of and specific resources for assessment
Assessment may occur on the job or in a simulated working environment. Access is required to real or appropriately simulated situations, including work areas, materials and equipment, and information on workplace practices and OHS practices.
Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.
Access must be provided to appropriate learning and/or assessment support when required. Where applicable, physical resources should include equipment modified for people with disabilities.
Method of assessment
Assessment must satisfy the endorsed Assessment Guidelines of the MEM05 Metal and Engineering Training Package.
Assessment methods must confirm consistency and accuracy of performance (over time and in a range of workplace relevant contexts) together with application of underpinning knowledge.
Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.
Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.
Assessment must confirm a reasonable inference that competency is not only able to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.
Assessment may be in conjunction with assessment of other units of competency where required.
Guidance information for assessment
Assessment processes and techniques must be culturally appropriate and appropriate to the language and literacy capacity of the candidate and the work being performed.
