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

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with L-36.com. I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerous of sources and is presented automatically. It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
