CAUTION
Never run the engine without air filter or rapid engine wear will be the result.
•
Check and clean the Air Filter regularly to ensure optimum performance.
•
Remove the air filter cover, take out the filter and wash in lukewarm water. Allow to dry completely and
then refit. If the air filter is damaged in any way, replace with an authorised replacement part.
SPARK PLUG
Check the spark plug periodically.
To ensure proper engine operation, the spark plug must be properly gapped and free of deposits.
1.
Remove the spark plug cap.
Remove the spark plug with a suitably size spanner or spark plug spanner. Take care not to allow dirt into the
cylinder whilst the spark plug is removed. Plug the hole with a clean rag (not tissue) during the operation.
WARNING
If the engine has been running, the exhaust (muffler) will be very hot. Be careful not to touch the exhaust
(muffler).
2. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped. If the spark plug is clogged
with carbon, clean thoroughly with a wire brush or replace with a Champion RDJ7Y or equivalent spark
plug.
3. Measure the plug gap with a feeler gauge. The gap should be 0.50 (0.020 in), correct as necessary by
bending the side electrode.
4. Attach the plug washer, thread the plug in by hand to prevent cross-threading.
5. When mounting a new spark plug, you should screw 1/2 more thread with the wrench after the washer is
compressed. If you are mounting an old one, you should only screw 1/8-1/4 more thread.
CAUTION
The spark plug must be securely tightened. An improperly tightened plug can become very hot and possibly
damage the engine. Never use a spark plug with an improper heat range.
IDLE ADJUSTMENT SCREW
The tines should not rotate when the engine is idling (throttle control lever not in use). If they do, turn the
adjustment screw anti-clockwise a few degrees. The adjuster is located just above and to the right of the
primer bulb. If after adjustment, the tines still rotate, it is recommended that the machine is inspected by your
local approved service/warranty dealer.
