CAUTION
Before and during the cleaning
operation, inspect the element for tears.
A torn element must be replaced.
Be sure 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.
CAUTION
● ● Don't use the cleaning solvent whose
flash point is low when cleaning the
element.
● ● Assemble the element completely or
damage severely the engine.
● ● Be careful not to allow water to go
inside the air cleaner element.
CAUTION
● ● When the assembly of air cleaner
element is not completely done,
dusts can go inside and damage
severely engine.
● ● Be careful not to allow water to go
into the element while washing.
CAUTION
More frequent servicing may be
performed on motorcycles that are used
under severe conditions, also clean the
air cleaner element when replacing the
oil to prevent damage of the engine.
