Oil Recommendations; Fuel Recommendations - Briggs & Stratton 290000 Operating & Maintenance Instructions

WARNING
Unintentional sparking can result in fire or electric shock.
Unintentional start-up can result in entanglement, traumatic
amputation, or laceration.
BEFORE PERFORMING ADJUSTMENTS OR REPAIRS
• Disconnect spark plug wire and keep it away from spark plug.
• Disconnect battery at negative terminal (engines with electric start.)
WHEN TESTING FOR SPARK
• Use approved spark plug tester.
• Do not check for spark with spark plug removed.

OIL RECOMMENDATIONS

Use a high quality detergent oil classified "For Service SF, SG, SH, SJ" or higher.
Do not use special additives.
SAE 30 40 F and higher (5 C and higher)
° °
is good for all purpose use above 40°F, use below 40°F will cause hard starting.
10W-30 0 to 100 F (- - 18 to 38 C)
° °
is better for varying temperature conditions. This grade of oil improves cold weather
starting, but may increase oil consumption at 80°F (27°C) or higher.
Check oil level frequently at higher temperatures.
Synthetic 5W-30 - - 20 to 120 F (- - 30 to 40
°
provides the best protection at all temperatures as well as improved starting with less
oil consumption.
5W-30 40 F and below (5 C and below)
° °
is recommended for winter use, and works best in cold conditions.
OIL CAPACITY
Approximately 1-1/2 quarts (48 ounces or 1.6 liters) when changing oil and filter.
(Oil capacity will be greater if engine is equipped with remote oil filter.)
CAUTION: Engine is shipped from Briggs & Stratton without oil. Before starting
engine, fill to FULL mark on dipstick with oil. Do not over fill.

ADDING OIL- SEE FIGURE
1. For first use or when performing oil change, add 1 liter (32 ounces).
2. Start and run engine at idle for 30 seconds. Shut engine off and wait 30
seconds.
3. Then add more oil slowly to bring level to FULL mark on dipstick. Check for
oil leaks.
4. Tighten dipstick firmly before starting engine.
CHECKING OIL
1. Place engine on level surface and clean around oil fill
2. Remove dipstick , wipe with clean cloth, insert and tighten down again.
Remove dipstick and check oil level.
3. Oil should be at FULL mark
4. Tighten dipstick firmly before starting engine.
OIL PRESSURE
If engine runs low on oil, an oil pressure switch (if engine is equipped) will either
activate a warning device or stop the engine. (Read the operating instructions
supplied by the equipment manufacturer to determine which way your engine is
equipped.) See Maintenance for further information.

. If oil is required, add slowly.

FUEL RECOMMENDATIONS

GASOLINE POWERED ENGINES
This engine is certified to operate on gasoline. The emission control system for
this engine is EM (Engine Modifications).
Always use gasoline that meets these requirements:
• Clean, fresh unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). If operating at high altitude, see
below.
• Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary
butyl ether), is acceptable.
• Use of any gasoline other than those approved above will void the engine
warranty. In some local areas fuel pumps may be marked if the gasoline
contains alcohols or ethers. If you are unsure about the gasoline you purchase
check with your fuel provider.
• Do not modify the engine fuel system or carburetor to run on alternative fuels.
• Never mix oil with gasoline.
All gasoline is not the same. If you experience starting or performance problems
after new gasoline has been used in your engine, switch to a different fuel
provider or change fuel brands.
CAUTION: Some fuels, called oxygenated or reformulated fuels, are fuels
blended with alcohols or ethers. Excessive amounts of these blends can damage
the fuel system or cause performance problems. If any undesirable operating
symptoms occur, use gasoline with a lower percentage of alcohol or ether.
FUEL STABILIZER
To protect the fuel system from gum formation, mix in a fuel preservative when
adding fuel. Briggs & Stratton recommends using FRESH STARTt fuel
stabilizer, available as a liquid additive, concentrated liquid cartridge or granular
additive.
HIGH ALTITUDE USE
At higher altitudes (over 5,000 feet), 85 octane/85 AKI (89 RON) gasoline can be
used. Operation at high altitude may require a high-altitude carburetor jet kit to
improve performance and decrease fuel consumption. See an Authorized Briggs
& Stratton dealer for more information.
ADDING GASOLINE
Clean around fuel fill before removing cap. Remove cap. Fill tank to
approximately 1-1/2 inches below top of neck to allow for fuel expansion. Be
careful not to overfill.
LIQUID PROPANE GAS (LPG)
NATURAL GAS (NG) POWERED ENGINES
• Use clean, dry fuel, free of moisture or any particulate material. Using fuels
outside the following recommended values may cause performance
problems.
• In engines set to run on LPG, commercial grade HD5 LPG is recommended.
Recommended fuel composition is fuel with a minimum fuel energy of 2500
BTU's/ft# with maximum propylene content of 5% and butane and heavier
gas content of 2.5% and minimum propane content of 90%.
• LPG or NG engines are certified to operate on liquid propane gas or natural
gas.
ADDING FUEL
Read the operating instructions supplied by the equipment manufacturer for
information on refueling natural or LP gas engine.
WARNING
LPG/NG Engines: The equipment on which this engine is mounted is
equipped with an automatic safety gas "fuel lock-off" valve. DO NOT operate
the equipment if the "fuel lock-off" valve is missing or inoperative, explosion
or fire could occur.
