III.2 Maintenance and repair costs of equipment

Maintenance and repair costs include the cost of labour and that of spare parts. If maintenance is carried out by the miller and/or a skilled mill worker, the labour costs for maintenance may be included int the overall labour costs of the mill (see section III.5). On the other hand, if the miller must secure regular maintenance services from local fitters, he will need to obtain an estimate of the yearly cost of these services.

The cost of spare parts is a function of the equipment yearly utilisation rate, the quality of the grain and the care with which the equipment is maintained. As a general rule, the yearly cost of spare parts may be estimated at 10 per cent of equipment cost.
