Spark plug
To ensure the engine is operating correctly, the spark plug (27) 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 (27) (Fig AN). With the supplied spark plug spanner
(34) remove the spark plug (Fig AO), and clean any deposits from the spark plug
(27) with a rag or damp cloth.
2. Visually inspect the spark plug (27). Discard the spark plug (27) if there is
apparent wear, or if the insulator is cracked or chipped.
3. Check that the end of the spark plug (27) 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 (27) in by hand to prevent cross-threading.
6. Once the spark plug (27) is seated, tighten with the supplied spark plug
spanner (34) to compress the washer.
NOTE. When installing a
new spark plug, tighten
1/2 turn after the spark
plug seats to compress
the washer.
7. Replace the spark plug
cap. ENSURE the cable
to the cap is in the TOP
position and is clear of
the carburettor rod.

Maintenance
Maintenance and Transporting
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.
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.
When transporting the lawnmower, the upper handle bars can be folded down
over the lower handles. To do this, disengage the lever/s from the secure
position, then loosen the knob on the upper handle bar locking lever/s (10)
until they are loose and allow the handle to be folded down over the lower
handle (9).
NOTE: Ensure the cable is not tangled or folded as this can cause damage to
the cable.
When the mower is ready to be used again, unfold the upper handle bar and
re-tighten the upper handle bar locking lever/s (10) per instructions on
page 23.
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.
