Spark Plug Maintenance
To ensure the engine is operating correctly, the spark plug must be properly
gapped and free of carbon deposits. Always check the spark plug cable is firmly
fitted to the top of the spark plug.
CAUTION: If the engine has been running, the muffler will be very hot.
Be careful not to touch the muffler.
WARNING: Ensure the motor is switched off before undertaking
this task.
1. Remove the spark plug cover, then remove the spark plug using the supplied
spark plug spanner (18) in an anti-clockwise direction, and clean any
deposits.
2. Visually inspect the spark plug (24). Discard the spark plug if there is apparent
wear, or if the insulator is cracked or chipped.
3. Check that the end of the spark plug (24) is not blackened by carbon build
up. Clean with a soft wire brush if necessary.
4. Measure the plug gap with a feeler gauge. Correct as necessary by bending
the side electrode. The gap should be 0.7 - 0.8mm.
5. Thread the spark plug (24) in by hand to prevent cross-threading.
6. Once the spark plug (24) is seated, tighten with the supplied spark plug
spanner (18) to compress the washer.
NOTE: When installing a new spark plug, tighten 1/2 turn after the spark plug
(24) seats to compress the washer.
NOTE: When reinstalling a used spark plug, tighten 1/8-1/4 turn after the spark
plug (24) seats to compress the washer.
CAUTION. The spark plug (24) must be securely tightened. An improperly
tightened spark plug (24) can become very hot and may damage the engine.
The spark plug (24) should be changed after approximately 25 hours of use,
or annually. Replacement spark plugs are available from purchase from lawn
mower or small engine repair shops, or online purchase is available from our
website https://help.tools/
