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
LP/NG FUEL INSTALLATION
The information in this instruction is offered to assist
you in providing the proper vapor fuel supply for your
engine. This information is only provided to advise
you of the engine’s requirements and the decisions
you must make. In no case should this information be
interpreted to conflict with any local, state or national
code. If in doubt, always follow local codes.
DANGER: FIRE - PERSONAL INJURY -
All fuel lines must be installed by a qualified fuel
supplier
.
The fuel source should be as close as possible to
the outdoor operating location. This will reduce the
installation cost of fuel runs. Connect the fuel supply
line to the inlet of the fuel demand regulator on the
unit using a locally approved flexible fuel line (see
table for recommended line size).
The pressure
supplied to the demand regulator must be FOUR
TO SIX OUNCES or 7 to 11 INCHES W.C. (water
column).
The primary regulator at the fuel supply
must be capable of delivering the proper volume of
fuel at this pressure.
Have your local fuel supplier install a protected fuel
connection at the outside operating location. He
should also install a lockable fuel shut off valve at the
connection point. Have your fuel supplier permanent-
ly install a flexible fuel line to the demand regulator on
the engine generator set.
DANGER: FIRE - PERSONAL INJURY -
The LP/NG fuel supply line must always be shut off
when the engine is not running. Failure to do so may
allow fuel to leak at the unit.
INSTALLING THE FUEL LINE
DANGER: PERSONAL INJURY
Units that are intended to be run unattended
MUST
have an electric fuel solenoid installed. This
solenoid MUST be wired to AUTOMATICALLY turn off
the fuel whenever the engine stops.
Unit location will determine the size of fuel line that
is required to supply the engine with a constant fuel
pressure. Refer to the tables below for fuel line size,
and recommended tank size. For distances of 100
feet and over, a two regulator fuel system is recom-
mended. This system consisting of a primary 10-15#
regulator at the tank and a 6 ounce secondary regula-
tor installed about 10 feet from the generator.
