PREFACE
Most accidents occur due to failure to observe basic safety rules and precautions. To prevent
accidents, it is important to prevent causes of accidents. Engineers performing the servicing
of this product on the market (hereafter referred to as SPs) must attend service skill classes
prior to providing servicing, as well as read this manual thoroughly to fully understand
safety precautions and appropriate servicing procedures.
Otherwise, servicing the product without adequate knowledge may result in unexpected
accidents.
As it is not possible to list all possible hazards which may occur during servicing, SPs
must always pay extreme safety precautions during servicing, apart from the precautions
described on the product and in this manual.
