WARNING: EQUIPMENT DAMAGE
This unit is12 Volt and is negative ground. Permanent
damage will occur if they are connected to a 24 Volt system
or a positive ground system. If you are using the truck
batteries to start these units, you may have to disable the
charging system to keep it from interfering with the vehicle
charging system.
Installation and servicing of batteries must only be
preformed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized
personnel away from batteries.
When installing or replacing batteries, use the proper
group/size starting battery. The battery should be a
maintenance-free lead acid design. Deep cycle batteries will
not work for this application.
CAUTION: PERSONAL DANGER
NEVER dispose a battery in a fire. The battery is capable of
exploding.
DO NOT open or mutilate the battery. Released electrolyte
is known to be harmful to the skin and eyes and to be very
toxic.
These engine-generator sets are all NEGATIVE ground. Be
very careful not to connect the battery in reverse polarity,
as this may short circuit the battery charging system on the
engine.
CAUTION
A battery presents a risk of electrical shock and high short
circuit current. The following precautions must be observed
when working with batteries:
1. Remove watches, rings, and other metal objects.
2. Use tools with insulated handles.
3. Check both the battery cable ends and the battery
posts to be sure they are free of corrosion.
4. Always connect the battery positive cable first and then
connect the battery negative cable. When removing
the battery cables from the battery, reverse the
procedure, disconnect the negative first and then the
positive
cable.
5. Be sure all connections are tight and coat the terminals
and cable ends with dialectic grease.
WARNING
The electrolyte is diluted sulfuric acid that is harmful to the
skin and eyes. It is electrically conductive and corrosive. The
following precautions must always be taken.
1. Always wear full eye protection and protective
clothing.
2. Where electrolyte contacts skin, wash off immediately
with
water.
3. If electrolyte contacts the eyes, flush thoroughly and
immediately with water and seek immediate medical
attention
4. Spilled electrolyte is to be washed down with an acid
neutralizing agent. A common practice is to use a
solution of one pound of bicarbonate of soda (baking
soda) to one gallon of water. The bicarbonate of soda
solution is to be added until the evidence of reaction
(foaming) has ceased. The resulting liquid is to be
flushed with water and the area dried.
DANGER: EXPLOSIVE FIRE RISK
1. Never smoke when near batteries.
2. Do not cause a flame or spark in the battery area.
3. Always discharge static electricity from your body
before touching batteries by first touching a ground
metal
surface.
SERVICING BATTERIES
Batteries used on these units may, over time, lose water.
This is especially true if you are using a trickle charger to
maintain your battery. When refilling the battery with
water, use only distilled water. Tap water will shorten the
service life of the battery.
Never fill the battery above the fill line. Over filling above
the upper level line may cause the electrolyte to overflow,
resulting in corrosion to the engine or nearby parts.
Immediately wash off any spilled electrolyte following the
procedure above.
NOTE: Always make sure that a new battery is fully charged
before installing it on a generator set. Failure to do so
can cause damage to the engine control module in the
generator set.
All connections must be clean and tight. Check the
electrolyte in the battery periodically to be sure it is
above the plates. Never allow the battery to remain in a
discharged condition.
BATTERY CHARGER
A three-stage, on-board marine battery charger is provided
standard on this unit. The charger is a 1.5 amp dual use
maintainer and charger designed to keep your batteries
fully charged by maintaining them automatically.
Make sure all DC battery connections are tight and clean.
Follow battery manufacturer’s recommendations.
This charger is mounted under the customer connection
on the control side of the generator. The charger will
