CHANGING ENGINE OIL
Change oil after first 8 hours of operation.
1. Change oil while engine is warm.
2. Remove oil drain plug to drain oil.
3. Refill with new oil of recommended SAE viscosity grade.
4. Fill to FULL mark on dipstick.
OIL FILTER
Ë
, IF EQUIPPED.
Replace oil filter after every 100 hours of operation or every season, whichever
occurs first.
1. Before installing new filter, lightly oil filter gasket with fresh, clean engine oil.
2. Screw filter on by hand until gasket contacts oil filter adapter. Tighten 1/2 to
3/4 turn more.
3. Refill engine with new oil of recommended SAE viscosity grade. See Adding
Oil under OIL RECOMMENDATIONS for procedure.
4. Start and run engine at IDLE to check for oil leaks.
5. Stop engine. Recheck oil level and add oil if required.
OIL PRESSURE
If oil pressure drops below 1-4 psi (.1-.2 kg/cm
is equipped) will either activate a warning device or stop the engine. Check oil
level with dipstick. If oil level is between ADD and FULL mark on dipstick, do not
try to restart engine. Contact an Authorized Briggs & Stratton Service Dealer. Do
not operate engine until oil pressure is corrected.
If oil level is below ADD mark on dipstick, add oil to bring level to FULL mark.
Restart engine and check oil pressure. If pressure is normal, continue to operate
engine.
Note: Oil pressure gauge, if engine is equipped, is supplied by
manufacturer of equipment.

SPARK PLUG
− SEE FIGURE
WARNING
DO NOT check for spark with spark plug removed.
Use only Briggs & Stratton Spark Tester, to check for spark.
• If engine is flooded, place throttle in FAST and crank until engine starts.
• The electrodes on the spark plug must be clean and sharp to produce the
powerful spark required for ignition. If the spark plug is worn or dirty the
engine will be hard to start.
Ê
• Ensure spark plug gap
is 0.76 mm or 0.030 in.
Note: In some areas, local law requires using a resistor spark plug to suppress
ignition signals. If this engine was originally equipped with resistor spark plug,
use same type of spark plug for replacement.

VALVE CLEARANCE

Gasoline Engines −
Check valve clearance yearly (intake and exhaust .10-.15 mm).
LPG / NG Engines −
Valve clearance must be checked after every 100 hours of operation. Adjust if
necessary.
MUFFLER
− SEE FIGURE
WARNING
Accumulation of debris around exhaust manifold/muffler
fire. Inspect and clean before every use.
If muffler is equipped with spark arrester screen
cleaning and inspection every 50 hours or every season. Replace if damaged.
