insulator is cracked or chipped.

3. Check that the end of the spark

plug 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.

Test the spark plug ignition

by disconnecting the spark

plug wire from the spark plug.

Hold the end of the spark plug

wire close to a metal surface.

If the spark plug is good, you

will see a spark or you'll hear

a crackling noise. This means that voltage is getting

through the wire to the spark plug.

Note:

This should only be carried out by a confident end

user as if not careful, this procedure may result in a non

lethal electric shock. Petrol fumes need to be considered

with an open spark and people with pace makers.

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 (9) while you

are transporting.
