11.1 Air filter (Fig. 3)
CAUTION! The engine MUST NOT be run without an air filter otherwise piston
and/or cylinder damage can occur. This type of damage will NOT be covered
under warranty.
Maintaining the air filter is very important. If dirt is allowed to get in to the
engine through improperly installed, serviced or inadequate filter elements, it
can damage and wear out the engine. ALWAYS keep the filter element clean.
▪ Press down on the latch tab on the top of the air filter housing and open the air filter cover.
▪ Remove the air filter.
▪ Clean the filter with a jet of dry compressed air until all dust and debris has been removed.
NOTE: DO NOT allow any dirt or debris to enter the carburettor chamber as
this could cause rapid engine wear.
▪ Reinstall the air filter and close the air filter cover.
11.2 Spark plug (Fig. 4)
▪ Carefully remove the spark plug HT lead cap.
▪ Remove the spark plug using the box spanner provided in an anti-clockwise direction.
▪ Check the spark plug for visible damage and electrode erosion.
▪ If damaged you MUST replace the spark plug.
▪ Remove carbon deposits from the spark plug using a soft wire brush.
▪ The spark plug gap should be 0.6 – 0.8mm. Check the gap using a feeler gauge and
adjust as necessary by carefully bending the side electrode to achieve the correct gap.
▪ Refit the cleaned and adjusted spark plug by hand to avoid cross-threading.
▪ After spark plug seats then tighten as necessary but avoid over-tightening.
▪ Re-attach the spark plug HT lead cap and spark plug maintenance cover.
