5. Thread the spark plug in by hand to prevent cross-
threading.
6. Once the spark plug is seated, tighten with a spark plug
wrench to compress the washer.
Note. When installing a new spark plug, tighten 1/2 turn
after the spark plug seats to compress the washer.
Note. When reinstalling a used spark plug, tighten 1/8-1/4
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.
Transporting
CAUTION. 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
• Hard 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 (2) 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.
• Protect all metal engine parts from corrosion by coating
them with oil.
• Remove the spark plug, put a few drops of oil into the
cylinder and then pull the recoil starter 2 to 3 times in
order to distribute the oil evenly. Replace the spark plug.
This closes the valves, and protects them from dust and
corrosion. 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.
