GENERAL INFORMATION
SECTION 1.3
PREPARATION BEFORE USE
GENERAL
The installer must ensure that the home standby
generator has been properly installed. The system
must be inspected carefully following installation. All
applicable codes, standards and regulations
pertaining to such installations must be strictly
complied with. In addition, regulations established by
the Occupational Safety and Health Administration
(OSHA) must be complied with.
Prior to initial startup of the unit, the installer must
ensure that the engine-generator has been properly
prepared for use. This includes the following:
❏An adequate supply of the correct fuel must be
available for generator operation.
❏The engine must be properly serviced with the
recommended oil.
FUEL
REQUIREMENTS
Generators with air-cooled engine have been factory
tested and adjusted using natural gas as a fuel. If LP
(propane) gas is to be used at the installation site,
adjustment of the generator fuel regulator will be
required for best performance. Refer to Test 63,
"Check Fuel Regulator" on Page 4.4-16 for fuel
regulator adjustment procedures.
❏When natural gas is used as a fuel, it should be
rated at least 1000 BTU’s per cubic foot.
❏When LP (propane) gas is used as a fuel, it should
be rated at 2520 BTU’s per cubic foot.
ENGINE
OIL
RECOMMENDATIONS
The primary recommended oil for units with air-cooled,
single cylinder or V-Twin engines is synthetic oil.
Synthetic oil provides easier starts in cold weather and
maximum engine protection in hot weather. Use high
quality detergent oil that meets or exceeds API
(American Petroleum Institute) Service class SG, SH,
or SJ requirements for gasoline engines. The following
chart lists recommended viscosity ranges for the lowest
anticipated ambient temperatures.
Engine crankcase oil capacities for the engines
covered in this manual can be found in the
specifications section at the beginning of the book.
LOWEST ANTICIPATED AIR COOLED ENGINE
AMBIENT TEMPERATURE RECOMMENDED OIL
Above 60 F. (16 C.) Use SAE 30 oil
20 -59 F. (-7 to 15 C.) Use SAE 10W-30 oil
Below 20 F. (-7 C.) SAE 5W-20/5W-30 oil
For all seasons Use SAE 5W-30
