2. Organizational preparation

To guarantee a trouble-free development of instructions, exercises and practical work it is necessary to prepare this training properly.

The following steps have to be taken:

2.1. Preparation of instructions on labour safety

Prior to the exercises a brief instruction on the proper use of tools and materials has to be given. This comprises hints for accident-free work.

The main emphasis is to be laid on:

- Hand hacksaws with crackless handles must be used only I
- Fixing components must not protrude at the side of the clamp dog!
- The guide hand must not work in the range above the vice I

Familiarity with these hints is to be confirmed by the trainee’s signature in a control book.

2.2. Provision of teaching aids

For demonstration purposes during instruction, a vice has to be installed at the place.

The “Trainees’ Handbook of Lessons - Manual Sawing” is to be handed out to the trainees.

When using the transparencies series of “Manual Sawing”, check whether they are complete (transparencies nos. 4.1. - 4.3.) and whether the overhead projector is functional.

(Check the operating conditions at the place of use and make sure of the proper mains supply!)

Surveys which are to be written on the blackboard have to be completed prior to instruction.

All the tools and accessories mentioned in section 3 (for sawing purposes) should be kept ready for demonstration.

2.3. Provision of working tools and materials

The “Instruction Examples for Practical Vocational Training -Manual Sawing” must be handed out to the trainees in sufficient copies to provide them with the theoretical foundations for the exercises to be performed.

The initial materials necessary for the exercises have to be laid out and prepared in sufficient numbers of copies according to the specifications mentioned in the “Instruction Examples...”.

Each trainee is to be provided with a workbench with a stationary vice (check the proper working height of the vice).

The trainees’ workbenches have to be fully equipped with tools and accessories according to the exercises planned. Do not forget to check this!

Recommended basic equipment:

- steel rule, try square, protractor
- steel scriber, prick-punch, dividers
- locksmith’s hammer
- hand hacksaw with various types of saw blades
- bastard and smooth files - 200 mm and 250 mm (flat and half round)
- vee clamps.

2.4. Time schedule

Time planning is recommended for the following training stages:

- introduction to the working technique in the form of instructions
- necessary demonstrations
- job-related instructions in performing the exercises
- performing the exercises
- recapitulation and tests.

The necessary time share depends on the respective training conditions. Most of the time is to be allocated to the exercises.
