Never use gasoline that has been stored for an extended
period of time as the fuel will lose its volatile properties
and you will be left with varnish residue. The varnish
like substance will clog the carburetor and will not burn
properly.
The use of fuel additives, 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.
See the engine manual for special instruction for operating
this unit at over 5000 feet.
BATTERY INSTALLATION
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.
This engine generator set is shipped with a bungee cord
for installation of the customer supplied battery in the unit’s
battery tray.
A 12 Volt battery, group 26 rated at 500 CCA or larger is
recommended for this electric start engine-generator set.
Follow the battery manufacturers recommendations for
servicing and charging prior to use. Connect the battery to
the electric start system using the cables provided.
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.
BATTERY CHARGING
Units have a small flywheel charger built into the engine
flywheel assembly for recharging the starting battery. This
flywheel charger generates a small AC current that passes
through a diode assembly to produce DC charging current
of about 1 to 3 Amps. This circuit is not designed to be used
as a battery charging circuit to recharge dead batteries.
OPTIONAL DOLLY KIT
An optional 4-wheel dolly kit is available for this generator.
The dolly kit comes with instructions and parts list.
CAUTION: EQUIPMENT DAMAGE
Be sure to check the wheels are installed properly
and the brake has been applied prior to operating the
generator. Allowing the unit to move while in use will
cause damage to the unit, drop cords or loads.
