Technical Information - Briggs & Stratton 084100 Manual De Operador

MAINTENANCE
WARNING
To prevent accidental starting, remove spark plug wire and
ground it before servicing.
Do not strike the flywheel with hammer or hard object. If
done, the flywheel may shatter during operation.
Do not tamper with links or other parts to increase engine
speed.
Regular maintenance improves performance and extends engine life.
More frequent service is required when operating in adverse conditions.
See any authorized service dealer for correct replacement parts. Other
parts may not perform as well, may damage the engine, result in injury, or
void your warranty.
Inspect / Change Spark Plug
Annually or every 50 hours of use inspect the spark plug.
1. Clean the spark plug with a wire brush removing the carbon buildup.
Check the condition of the plug for cracking or damage. Replace as
necessary.
2. Set the spark plug gap to .030 in. (0.75 mm).
3. Install the spark plug finger tight, then torque to 175 in‐lbs.
TROUBLESHOOTING
Engine will not start
Out of fuel
•
Prime engine
•
If engine is cold, ensure choke is set correctly.
•
Add fuel
Bad or stale fuel
•
Drain the fuel tank and the float bowl of the carburetor. Fill the tank
with clean fresh, properly mixed fuel. Call or see an authorized service
dealer if you need help.
Engine flooded
•
Spark plug may be fouled.
Fouled spark plug / engine fails to produce spark
•
Remove spark plug and clean it. Check the spacing on the electrode
and set the gap to the correct dimension. See Maintenance Section. If
plug is damaged, replace with a new spark plug.
•
Ensure the spark plug is installed and wire is connected.
Engine runs rough or smokes
Engine smokes excessively (some smoke is normal)
•
There may be a slight oil accumulation in the crankcase upon starting.
This is normal.
•
Some smoke is normal. If smoke is excessive or heavy, ensure choke
is in the OFF position.
•
Gasoline/oil mixture is too rich. Drain fuel tank and fill with correct
gasoline/oil mixture.
Engine lacks power or back fires
•
Check for bad or stale fuel.
•
The exhaust system maybe clogged. See an authorized service
dealer for assistance.
STORAGE
Engines stored over 30 days need to be protected or drained of fuel to
prevent gum from forming in fuel system or on essential carburetor parts.
1. Add a fuel stabilizer/conditioner to the fuel in the fuel tank as directed.
2. Run the engine for 5 minutes to distribute the conditioned fuel through
the fuel system.
3. Stop the engine and allow it to cool.
4. Use a hand pump to pump the fuel from the fuel tank into an approved
fuel container, or run the engine until it stops.
5. Start the engine and run it until it stops.
Fig. 7
6. Choke or prime the engine, start it a third time, and run the engine until it
will not start.
7. Slowly pull the recoil starter until you feel resistance due to compression
pressure, then stop.
8. Release the starter tension gradually by allowing the rope to go back
slowly to prevent engine from reversing due to compression pressure.
9. Dispose of unused fuel properly. Recycle it according to local codes, or
use it in your automobile.

TECHNICAL INFORMATION

Engine Power Rating Information
The gross power rating for individual gas engine models is labeled in
accordance with SAE (Society of Automotive Engineers) code J1940
(Small Engine Power & Torque Rating Procedure), and rating performance
has been obtained and corrected in accordance with SAE J1995 (Revision
2002‐05). Torque values are derived at 3060 RPM; horsepower values are
derived at 3600 RPM. Actual gross engine power will be lower and is
affected by, among other things, ambient operating conditions and
engine‐to‐engine variability. Given both the wide array of products on
which engines are placed and the variety of environmental issues
applicable to operating the equipment, the gas engine will not develop the
rated gross power when used in a given piece of power equipment (actual
"on‐site" or net power). This difference is due to a variety of factors
including, but not limited to, accessories (air cleaner, exhaust, charging,
cooling, carburetor, fuel pump, etc.), application limitations, ambient
operating conditions (temperature, humidity, altitude), and
engine‐to‐engine variability. Due to manufacturing and capacity limitations,
Briggs & Stratton may substitute an engine of higher rated power for this
Series engine.
