Important
This Technical Data Sheet and the corresponding Installation Instructions provide important information to ensure the installed
engine will operate according to the design specification in the Volvo Penta application for certification.

Requirements marked with are considered as critical for exhaust emissions compliance according to the design
specification in the Volvo Penta application for certification.

Failing to follow and meet these instructions and requirements when installing a certified engine in a piece of nonroad equipment
for use in the United States violates U.S. federal law (40 CFR 1068.105(b)), subject to fines or other penalities as described in the
Clean Air Act.
