Disconnect the caps «3» of the high
voltage cables from the spark plug.
•
Clean off any trace of dirt from the
spark plug base by blowing com-
pressed air. Unscrew the spark plugs
and remove them from their seat, being
careful not to let dust or any other sub-
stance come into the cylinder.
•
Check that the spark plug electrode
and the centre porcelain are free of
carbon deposits or signs of corrosion.
If necessary, clean using suitable
spark plug cleaners, a wire and/or met-
al brush.
•
Blow with a strong air blast to avoid re-
moved dirt getting into the engine. Re-
place the spark plug if there are cracks
on its insulating material, corroded
electrodes or large deposits.
•
Check electrode gap with a thickness
gauge and adjust if necessary by care-
fully bending the earth electrode.
•
Make sure the washer is in good con-
ditions. Once the washer is fitted, fin-
ger tight the spark plug to avoid
damaging the thread.

that it does not get detached due to en-
gine vibrations.
