Air filter
Inspect every 4000 km, replace every 12000km.
If the air filter is blocked by the dust, the air intake
resistance will increase, which will result in lower engine
output and fuel consumption increased. It should inspect
and clean the components according to the following
methods.
Disassemble
Disassemble the screws on the side cover of the air
filter, and then remove the side cover of the air filter①. As
in Fig.2.2.8.
Unscrew the wing bolt④, and separate the filter
element from the filter element bracket⑤
Finally take out the air filter element⑥As in Fig.2.2.9
Clean
Clean according to the following steps:
Put the non-combustible washing liquid into the
washing plate of appropriate size, and immerse the filter
element of the filter in the washing liquid for washing.
Press the washed filter element with the palm of both
hands to squeeze out the washing liquid. Do not twist the
filter element to avoid cracking.
Immerse the filter element in the oil pool and squeeze
out the oil in the filter element to make it slightly moist but
not dripping with oil. As in Fig.2.2.11.
Note：
Before and during cleaning, check the filter element for
cracks. If damage is found, the filter element should be
replaced
.
Assemble the cleaned filter in the reverse order of removal. It
must be confirmed that the filter element is firmly installed in
the specified position and sealed reliably.
Note：
When the filter element is not installed, do not run the engine to avoid
wearing the piston and cylinder.
A: Non-combustible cleaning fluid
B: Engine oil SAE#30 or SAE10W/40
Note：
If driving in dusty conditions, clean the filter
more frequently.Not using a filter element or
using a broken filter element will definitely
lead to accelerated engine wear.Ensure that
the air filter is always in good condition.The
life of the engine depends mainly on this
component.
