Safety Information:
Introduction:

• The Service Manual contains descriptions and service instructions for the Volvo Penta products and versions of products listed in the list of contents. This manual should be used in conjunction with the Service Manual Technical Data for the engine in question.
• Make sure that the right service literature is used. Read the available safety information and the General information and Repair instructions sections in the Service Manual carefully before starting service work.

This Service Manual contains descriptions of and repair instructions for the standard versions of the TAD1240GE, TAD1241GE/VE, TA1242GE/VE and TWD1240VE model engines. The Service Manual may show procedures performed on any of the engines listed above so the illustrations and photographs showing certain details may not be completely accurate in some cases. However, the repair methods are all essentially the same.

• The engine model and serial number are given on the data plate (see “Technical data TAD1240GE, TAD1241GE/VE, TAD1242GE/VE and TWD1240VE”). The engine model and serial number should always be given in all correspondence concerning any of the engines.
• The Service Manual is primarily produced for Volvo Penta service facilities and their qualified personnel. It is therefore assumed that persons using the manual have the necessary basic knowledge and can carry out the mechanical and electrical tasks that occur in their profession.
• Volvo Penta is continuously developing its products and we therefore reserve the right to introduce changes and modifications. All the information in this manual is based on product data available at press time. Any significant changes that have been introduced in the product or service methods after that date will be announced in the form of Service Bulletins.

Spare parts :

• Spare parts for the electrical and fuel systems are subject to different national safety requirements. Volvo Penta Original Spare Parts meet these requirements.
• All types of damage occurring as a result of using non-original Volvo Penta spare parts for the product in question will not be covered under the terms of warranty as provided by Volvo Penta.
