running Approaching ato avoid hot surfaces exhausts use protective goggles when charging4Never remove heavy components alone evenwhere secure lifting equipment such as securedblocks are being used Even where lifting equipment is being used it is best to carry out thework with two people one to operate the and the other to ensure that components are not trapped and damaged when beinglifted When working onboard ensure that thereis sufficient space to remove components without danger of injury or in the electrical system ignitionsystem gasoline enginesVolvo Penta products are designed and constructed to minimize the risk of fire and explosion The engine must not be run in areaswhere there are explosive use fuels recommended by Volvo Penta Refer to the Instruction Book The use oflower quality fuels can damage the engine Ona diesel engine poor quality fuel can cause thecontrol rod to seize and the engine to overrevwith the resulting risk of damage to the engineand personal injury Poor fuel quality can alsolead to higher maintenance costsGeneral We therefore reserve the right to make changesharmful to the environment if used incorrectly 1033 the tightening torque stated in the
