• Pull the HT lead from the spark plug.
• Using the spark plug socket and 'T-'bar (supplied) remove
the spark plug. (Fig. 20)
A serviceable spark plug in good condition should exhibit light
tan deposits on the plug nose. Remove these deposits with a
stiff brass wire brush.
• Check the electrode gap of the plug using a set of feeler
gauges.
• Adjust if necessary. The gap should be 0.7mm to 0.8mm
• Re-install the spark plug.
• Hand tighten the plug using the spark plug socket.
• Only use the spark plug socket to produce the gas tight
seal which is achieved by the last ½ turn of the spark plug.
• Reattach the HT lead to top of the spark plug.
3. Air Filter
WARNING: Never run the engine without the air filter
element fitted. After approximately 50 hours of use the air
filter element should be removed from its housing, cleaned
and refitted.
Note: The air filter may require more frequent attention if the
operating environment is especially dusty.
To remove:
• Ensure that the engine is switched 'OFF' and the fuel tap
is in the 'OFF' position. The engine should be cold.
• Unscrew the finger screws from the Air Filter cover plate
and remove it and the foam element and element holder.
(Fig. 21)
• Carefully store these parts for later re-installation.
The Air Filter Element is washable. Clean the element
thoroughly using an environmentally friendly water based
degreasing agent. Allow to dry naturally. Do not refit a wet or
damp element.
• When dry the element should be lightly sprayed with light
machine oil. This will improve the efficiency of the air filter.
To refit:
• Install the element holder and the cleaned and oiled foam
element into the Air Filter Housing.
• Replace the cover plate and tighten the two finger screws.
