Zontes ZT125T-D Maintenance Manual page 41

●The vehicle must be parked on a flat and stable ground or a
lifting platform.
●The operation can only be performed after the engine has
cooled down completely.
●The air filter element shall be checked every 4000km (2485
miles) or 15 months (whichever comes first), and replaced
every 8000km (4971 miles) or 30 months (whichever comes
first). The sponge filter element at the air inlet shall be
replaced every 4000km (2485 miles) or 15 months
(whichever comes first).
●The air filter element and the engine air inlet element
should be cleaned regularly in accordance with the provisions
of the regular maintenance and lubrication table.
●If you often ride in humid or dusty areas, you should check
the air filter element more frequently. Be sure to inspect the
waste oil pipe of the air filter frequently.
●If the filter element is damaged, it must be replaced, and
otherwise the dirt will be directed into the engine and cause
damage to the engine.
●Ensure that the filter element is assembled in place.
●If the air filter is clogged with dust, the air intake resistance
will increase and the output power will decrease.
●If the filter element of the engine air intake is blocked by
dust, the air intake resistance will increase, which will reduce
the heat dissipation of the belt and affect the life of the belt.
●If the replacement period is not reached, the surface of the
filter element is clean without damage, and you can use a
dust blow gun to blow air from the clean side of the filter
element to blow away the dust on the surface of the filter
element.
●Do not let water enter the air filter when washing the
vehicle.
