Air Filter; Sparking-Plug Check - GAS GAS HALLEY 125 SM/EC 09 User Manual

AIR FILTER

The adequate performance and durability of the various engine
components (connecting rod, piston, piston rings, crank bearings,
even the cylinder) depend to a great extent on the air filter being
clean and properly lubricated.
WARNING
Always clean the filter in an area that is properly ventilated and free
from sparks or flames in the vicinity (this includes any powerful light
sources). Do not use petrol to clean the filter, as this might cause
an explosion.
To access the filter, remove the screw of the seat.
Once removed the seat, check the condition of the filter housing,
wash the filter if it is dirty, and then lubricate it. To lubricate the filter,
apply a few drops of oil to soak the foam and press it with one hand
without twisting it, then make sure to replace it correctly in its housing;
otherwise, unfiltered air might reach the carburettor and cause serious
damage to the moped.
