Safety information:
Introduction:

• The workshop manual contains descriptions and repair instructions for products or product versions
  noted in the table of contents, supplied by Volvo Penta. This manual should be used together with
  the workshop manual Technical data for each engine. Check that you have the correct workshop manual
  for your engine.
• Read this safety information and the workshop manual General information and Repair instructions care-
  fully before service work is started.

General information:
About this workshop manual:

• This workshop manual contains descriptions and re- pair instructions for the standard versions of
  the TAD1250VE, TAD1251VE and TAD1252VE engines.
• The workshop manual can illustrate tasks done on any of the engines noted above. This means that
  the illustrations and photographs which clarify certain de- tails might not entirely correspond.
  The repair meth- ods are similar in all important respects, however. The engine designation and
  number are noted on the type plate (please refer to “Technical Data TAD1250VE, TAD1251VE,
  TAD1252VE”).
• The engine designation and number must always be given in all correspondence about an engine.
  The workshop manual is produced primarily for the use of Volvo Penta workshops and service techni-
  cians. For this reason the manual presupposes a cer- tain basic knowledge and that the user can
  carry out the mechanical/electrical work described to a general standard of engineering competence.
  Volvo Penta constantly improves its products, so we reserve the right to make modifications without
  prior notification. All information in this manual is based on product data which was available up
  to the date on which the manual was printed. Any material changes introduced into the product or
  service methods after this date are notified by means of Service Bulletins.
