Briggs & Stratton recommends the use of their war-
ranty certified oils for best performance. Other high-
quality detergent oils are acceptable if classified for
service SF, SG, SH SJ or higher. Do not use special
additives.
GASOLINE
When using gasoline, always use fresh, clean,
unleaded fuel. This engine is certified to operate on
unleaded gasoline with a minimum octane rating of
87 or higher. Gasoline containing no more than 10%
ethanol is acceptable.
CAUTION: EQUIPMENT DAMAGE
Do not use unapproved gasolines, such as E15 or
E85.
Do not mix oil in the gasoline. Use of unap-
proved fuels will damage the engine components
and void the engine warranty.
Use of fuels with content of ethanol greater than
shown above may cause starting and/or perfor-
mance problems. Always insure that the fuel is
clean and free of all impurities.
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when
proper precautions are not taken.
Never use gasoline that has been stored for an ex-
tended 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
These engine generator sets are shipped with a bat-
tery rack, and battery cables installed. A battery tie
down kit is shipped loose with each unit.
You will need to purchase and install a battery to op-
erate this engine generator set. A twelve volt battery,
group 6 rated at 500 CCA or larger is recommended
for this electric start engine generator set. Follow the
battery manufacturer’s recommendations for servic-
ing 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 and tight. Reverse the
sequence when disconnecting, disconnect the nega-
tive cable first. These engines produce enough direct
current to keep a battery charged under normal oper-
ating conditions, but were not intended to be used as
a battery charger.
