Special notes

1 Definition

Worksite documentation refers to instructions to staff on policy and procedures (including the application of legislation to worksite situations), which are formally documented, and are available for reference at the worksite. Examples are standard operating procedures, specifications, manuals, and manufacturer's information. For people already employed in the industry, the worksite referred to is their employer's. For other people, the worksite will be either a local worksite or a typical New Zealand worksite. For these learners, the Industry Training Organisation will ensure that the training given by accredited providers meets these standards.

2 The following apply to the performance of all elements of this unit standard:

a All work practices must meet recognised codes of practice and documented worksite health and safety and environmental procedures (where these exceed the code) for personal, product and worksite health and safety, and must meet the obligations required under current legislation, including the Health and Safety in Employment Act 1992, the Resource Management Act 1991, and their subsequent amendments.

b All work practices must meet documented worksite operating procedures. This includes the recording (by electronic or non-electronic means) of activities, events, and decisions.

c All evidence of communications gathered in relation to this unit standard must be in accordance with worksite procedures for content, recipient, timing, and method.

Elements and performance criteria

Element 1

Demonstrate knowledge of factors affecting the finished quality of machined timber.

Performance criteria

1.1 Variables affecting the finished quality of machined timber are explained.

Range machine variables – cutting speed, cutter pitch, feed speed, cutting angles and cutter sharpness;

timber variables – moisture content, grade, age.

1.2 Influences of end use application and machine capability on determining feed speed are described.

1.3 The relationship between wood type, wood density, timber grade and moisture content on cutter wear are explained.

Range moisture content – green and dry;

grade – clear and knotty.

1.4 Operating methods for ensuring best product with least downgrade are explained.

Range minimum stock removal on bottom and fence side heads.

1.5 Machine defects are identified from given samples and their causes are explained.

Range raised grain, burn marks, cutter chip marks (raised line), sniping, torn grain.

Element 2

Manage hazards associated with setting up a planer for dress four sides.

Performance criteria

2.1 Hazards associated with setting up a timber planer for dress four sides are identified and actions to be taken to isolate, minimise or eliminate the hazard are described in accordance with worksite documentation.

Range hazards may include but are not limited to – tools left in the machine, components coming loose, guards not in place, loose clothing, inadvertent starting of the machine, noise.

2.2 Safe work practices associated with setting up a timber planer for dress four sides are identified and used in accordance with worksite documentation and legislative requirements.

Range practices may include but are not limited to – isolation procedures, lock-outs, emergency stops, machine guarding, wearing appropriate safety equipment.

Element 3

Clean and strip a dress four sides planer.

Performance criteria

3.1 Planer is prepared for set-up in accordance with manufacturer’s recommendations.

Range components cleaned, spindles oiled.

3.2 Machine is fully isolated in accordance with legislative requirements and worksite documentation.

3.3 Planer and work areas are cleaned of all foreign matter that could affect set-up operations.

3.4 Planer components are checked and remedial action is taken when worn or damaged parts are found, in accordance with manufacturer’s recommendations and worksite documentation.

Range components – feed rollers, chip breakers, fences, beds, pressures, plates, lubrication system, extraction system, hoods and guards;

action – repair, replace, arrange for servicing.

3.5 Cutterheads or cutters are removed and stored in accordance with worksite documentation.

Element 4

Explain the sequence of setting up a planer for dress four sides.

Performance criteria

4.1 A planer is described.

Range planer – any with which the trainee is familiar;

machine make, model, layout of cutterheads, spindle speed.

4.2 Steps required to set-up the planer are outlined.

4.3 Reasons for using a systematic approach to setting up a planer are described.

Element 5

Select and fit preset cutterheads for dress four sides.

Performance criteria

5.1 Cutterheads that will produce required planed timber size are selected and are checked for absence of defects and damage.

5.2 All cutters are checked and locked into the cutterhead in accordance with manufacturer's specifications.

5.3 Cutterheads are fitted onto spindles and locked in accordance with manufacturer’s specifications.

5.4 Outrigger bearings are fitted according to manufacturer’s and machine specifications.

Element 6

Complete set-up, make adjustments and calculations for dress four sides.

Performance criteria

6.1 Cutterheads are adjusted to required size and locked, in accordance with manufacturer’s recommendations.

Please note

Providers must be accredited by the Qualifications Authority, or an inter-institutional body with delegated authority for quality assurance, before they can report credits from assessment against unit standards or deliver courses of study leading to that assessment.

Industry Training Organisations must be accredited by the Qualifications Authority before they can register credits from assessment against unit standards.

Accredited providers and Industry Training Organisations assessing against unit standards must engage with the moderation system that applies to those standards.

Accreditation requirements and an outline of the moderation system that applies to this standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The AMAP also includes useful information about special requirements for organisations wishing to develop education and training programmes, such as minimum qualifications for tutors and assessors, and special resource requirements.
