AIR CLEANER

NOTE :
Clean at least Every month.
If the air cleaner is clogged with dust, intake resis-
tance will increased with a resultant decrease in
output and an increase in fuel consumption.
Check and clean the element in the following man-
ner.
● Stand the vehicle in the standing position.
● Remove the four bolts ①.
● Remove the clamp screw ②.
● Remove the air cleaner case ⑤.
● Remove the element ④ from the cap ③.
● Fill a washing pan of a proper size with nonflammable
cleaning solvent. Immerse the element in the cleaning
solvent and wash it clean.
● Squeeze the cleaning solvent out of the washed element
by pressing it between the palms of both hands : do not
twist or wring the element or it will develop tears.
● Immerse the element in HYOSUNG genuine oil and
squeeze the oil out of the element leaving it slightly wet
with oil.
● Fit the cleaner element to frame properly.
CAUTION
� � Before and during the cleaning operation,
inspect the element for tears. A torn element
must be replaced.
� � Be sure to position the element snugly and cor-
rectly, so that no incoming air will bypass it.
Remember, rapid wear of piston rings and
cylinder bore is often caused by a defective or
poorly fitted element.
