Have qualified personnel install batteries and/or perform electrical system maintenance.
•
Make sure that ALL battery switches are turned Off BEFORE performing any work in the
engine spaces.
DANGER !

cal devices:
1. Check the bilge areas for fuel vapors or leaking fuel. If you see leaking fuel or smell
fuel vapors:
a. Do NOT start the engines or generator, do NOT turn On any electrical devices, extinguish
ALL cigarettes, cigars, and other sources of flame or ignition.
