Spark plug
To ensure the engine is operating correctly, the spark plug (20) 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. The spark plug should be
changed after approximately 25 hours of use, or annually.
CAUTION. If the engine has been running, the muffler will be very hot.
Be careful not to touch the muffler.
1. Remove the spark plug cap (20) (Fig AB). Using the supplied spark plug
wrench (30) remove the spark plug (Fig AC), and clean any deposits from
the spark plug (20) with a rag or damp cloth.
2. Visually inspect the spark plug (20). Discard the spark plug (20) if there is
apparent wear, or if the insulator is cracked or chipped.
3. Check that the end of the spark plug (20) 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 (20) in by hand to prevent cross-threading.
6. Once the spark plug (20) is seated, tighten with the supplied spark plug
wrench (30) to compress the washer.
NOTE. When installing a new spark plug, tighten 1/2 turn after the spark
plug seats to compress the washer.
CAUTION. The spark plug must be securely tightened. An improperly
tightened spark plug can become very hot and may damage the engine.
Replacement spark plugs are available from purchase from lawn mower
or small engine repair
shops

Storage and Transporting
Transporting
WARNING: Ensure the engine is not running and has cooled before
transporting.
WARNING: If the engine must be tipped to transport equipment or to
inspect or remove grass, keep the spark plug upwards.
Transporting or tipping the engine spark plug down may cause:
• Smoking
• Difficulty starting
• Spark plug fouling
• Oil saturation of the air filter
Ensure the storage area is free from excessive humidity and dust.
Drain the fuel tank and carburettor.
WARNING. Fuel is extremely flammable and explosive under
certain conditions.
Do not smoke or allow flames or sparks in the area.
Note. Be aware to not hit or cut the fuel tank while you are transporting.
Storage
• When you finish working, clean the engine completely, making sure there is
no grass or dirt on the engine.
• Store the engine away from direct sunlight.
• At the end of the season, give the engine an overall cleaning and a thorough
check.
• Whenever the machine is not used for a long period of time, proceed
as follows:
• Empty the fuel tank completely.
• Empty the Carburettor bowl of all fuel by starting the lawn mower and
letting it stop when the fuel is all used in the bowl.
• Protect all metal engine parts from corrosion by coating them with oil.
• Completely change the engine oil.
• Coat areas that may rust with a light film of oil. Cover the engine and store it
on a level surface in a dry, dust free area.
