NOTICE
!
DO NOT allow the generator to run
out of fuel. Fuel injected generators
require air to be removed from the fuel
delivery system before initial start-up
or if the generator is allowed to run
out of fuel. Continued attempts to
start the generator with air in the fuel
system can lead to engine damage or
erratic operation. Air must be purged
by your servicing dealer only.

DC Electrical System Maintenance
At least semi-annually, spray all exposed
electrical components behind the helm and
in the plugs
with a protector specific for elec -
trical connections.
Make sure to check that all below-deck wiring
is properly supported, the insulation is sound,
and there are no loose or corroded terminals.
Clean any corroded terminals thoroughly with
sandpaper, or replace them. Tighten securely
and spray with a metal and electrical protec-
tor. Inspect all engine wiring.
Check the electrolyte level in the batteries
regularly and add distilled water as neces-
sary. If the batteries are frequently charged
by a battery charger, check the electrolyte
level more often. The correct fluid level in the
cells is approximately 1/4 to 1/2 inch above
the plates. If fluid is needed, fill to the proper
level with distilled water ONLY. DO NOT over
-
fill. Some batteries are sealed and cannot be
filled.
Keep the tops of any battery clean and dry.
Dirt and water can conduct electricity from
one post to the other and can cause battery
discharge or engine warnings.
