10. MAINTENANCE
10.1 CLEANING THE AIR FILTER –
FIGS. 8 - 9
A dirty, clogged air filter will restrict the air flow
in to the engine and will cause rough running. It
will increase fuel consumption and may result in
starting problems.
Attention! Stop the engine before removing the air
filter assembly.
– Set the choke lever
(4)
to the OFF position to
prevent any debris entering the carburettor inlet.
– Using the supplied hex key
(22)
, undo the
retaining bolt on the air filter housing cover (1).
– Remove and wash the foam air filter element
(1.2)
in warm soapy water to clean it. Do not
use solvents to clean it.
– Allow the filter to dry 100% before refitting it on
to the engine.
Replace the filter if it appears worn or damaged.
10.2 SPARK PLUG MAINTENANCE –
FIG. 10
Over time the spark plug can become
contaminated. This can be due to adverse running
conditions such as, working with part throttle for a
prolonged period or a fuel mix containing too much
oil. This contamination can build up causing the
engine to run roughly, reduce the fuel consumption
or create starting problems.
– Without using any tools [so as to avoid
damaging the H.T. lead] remove the lead
(22)
from the back of the spark plug.
– Using the spark plug spanner
(20)
, turn the
spark plug anticlockwise to remove it.
– Clean the spark plug and check the electrode
gap. Maintain a gap of 0.6 to 0.7mm.
