WARNING: FIRE DANGER
Diesel fuel is flammable and can be ignited, causing or
enlarging fires when proper precautions are not taken.
Never use fuel that has been stored for an extended period
of time. Fuel will lose its volatile properties and you will
be left with a ‘gum’ or varnish residue. This varnish-like
substance will clog the filters, fuel lines, and injectors. Old,
contaminated, stale fuel will not burn properly. The use of a
fuel additive, such as Sta-Bil, or an equivalent will minimize
the formation of fuel gum deposits. If a unit has been out of
operation for an extended period of time, it is best to drain
old fuel from the engine and replace with fresh fuel before
attempting to start.
BATTERY INSTALLATION
You will need to connect this unit to a battery to operate
it. Cables have not been provided as length are going to
vary depending on your installation. These engines are
all negative ground. The positive battery cable must be
connected to the open large terminal on the start solenoid
(This terminal may have a small 16 GA. wire on it for the
charging circuit). The negative cable should be attached
to a good ground on the engine. This is usually one of the
engine mounts.
Start Solenoid terminals
A twelve volt battery, rated at 300 CCA or larger is
recommended for this electric start generator set. Follow
the battery manufacturer’s recommendations for servicing
and charging prior to use.
CAUTION: EQUIPMENT DAMAGE:
These electric start engines are NEGATIVE GROUND.
Use extreme caution when connecting the battery.
Connect the NEGATIVE battery terminal to GROUND.
For your safety, always connect the positive battery cable to
the “bat+” terminal first. Then connect the negative battery
cable to the “Bat-” terminal. Make sure all connections are
clean an tight. Reverse the sequence when disconnecting,
disconnect the negative cable first. These engines produce
enough direct current to keep the battery charged under
normal operating conditions, but were not intended to
be used as a battery charger.
WARNING: PERSONAL INJURY:
Lead acid batteries produce explosive hydrogen gas
when charging. Keep sparks, flames, and burning
cigarettes away from the battery. Ventilate the area
when charging or using the battery in an enclosed
space. Lead acid batteries contain sulfuric acid, which
causes severe burns. If acid contacts eyes, skin, or
clothing, flush well with water. For contact with the
eyes, get immediate medical attention.
CAUTION:
Do NOT open or mutilate the battery. Released
electrolyte is known to be harmful to the skin and eyes
and to be very toxic.
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 first and then
connect the battery negative cable. When
removing the battery cables from the battery
reverse the procedure, disconnect the negative
cable first and then the positive cable.
5. Be sure all connections are tight and coat the
terminals and cable end 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 be 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 water and the area
dried.
DANGER: EXPLOSIVE FIRE RISK
Never smoke when near batteries. Do not cause a
flame or spark in the battery area. 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
