Air Filter Maintenance

WARNING: Ensure the motor is switched off

before undertaking this task.

IMPORTANT: A dirty air filter (20) will restrict air flow to the carburettor.
To prevent carburettor malfunction, service the air filter (20) regularly.
Check that the air filter (20) is clean and dry of dirt.
Filters thick with debris will not allow the engine to breathe and result in

difficult starting and poor engine performance.
The air filter (20) should be checked after approximately 25 hours of use,

or annually.
1. Open the air filter cover (21) by pushing in the

front tab to release the clip, and then pushing the

cover back and away to release the 2 back clips

and the full air filter cover (Fig Z).

2. Remove the foam element (Fig AA).
3. If the air filter (20) is excessively dirty, replace with

a new filter.

4. Wash the air filter (20) in liquid detergent and

water. Then allow it to thoroughly air dry.

Do not oil the air filter (20).

5. Re-install the air filter (20) and put the air filter

cover (21) back on ensuring the clips are securely

in place.

CAUTION: Never use fuel or low burning paint

solvents to clean the air filter (20). A fire or explosion

could result.
CAUTION: Ensure the air filter (20) is dry before re fitting.
Replacement air filters are available from www.extrabattery.com.au

or by calling Customer Service on 1800 909 909.

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 cap, then remove the spark plug using the supplied

spark plug spanner (28) 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 (28) 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.
