Valve Clearance - HYOSUNG RX 125 Service Manual

2-5 PERIODIC MAINTENANCE
● Fill a washing pan of a proper size with non-
flammable cleaning solvent. Immerse the
elements in the cleaning solvent and wash
them clean.
● Squeeze the cleaning solvent out of the washed
element by pressing it under 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 elements to the cleaner case 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
correctly, 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.
