Inspecting Idling Speed; Changing Engine Oil - Coleman F15BM Owner's Manual

4. Reinstall the filter element in the cup. Make sure the O-ring is in position in the cup. Firmly screw the
cup onto the filter housing.
5. Attach the filter assembly to the bracket so that the fuel hoses are attached to the filter assembly. Run
the engine and check the filter and lines for leaks.
A diagnostic tachometer should be used for this procedure. Results may vary depending on whether
testing is conducted with the flushing attachment, in a test tank, or with the outboard motor in the water.
1. Start the engine and allow it to warm up fully in neutral until it is running smoothly.
2. Verify whether the idle speed is set to specification.
CAUTION:
Correct idling speed inspection is only possible if the engine is fully warmed up. If not warmed
up fully, the idle speed will measure higher than normal. If you have difficulty verifying the idle peed,
or the idle speed requires adjustment, consult a dealer or other qualified mechanic.
WARNING:
Avoid draining the engine oil immediately after stopping the engine. The oil is hot and
should be handled with care to avoid burns.
Be sure the outboard motor is securely fastened to the transom or a stable stand.
CAUTION:
Change the engine oil after the first 10 hours of operation, and every 100 hours or at 6-month
intervals thereafter. Otherwise the engine will wear quickly.
Change the engine oil when the oil is still warm.
