Checking Air Cleaner Element (If necessary)
1. To clean the element, use clean dry compressed air on the inside
of the element.
Air pressure at the nozzle must be under 205 kPa (2.1 kgf/cm
2
,
30 psi).
2. If the element is stained with carbon or oil, replace the element.
■
•Make sure the wing bolt for the element is tight enough. If it
is loose, dust and dirt may be sucked, wearing down the
cylinder liner and piston ring earlier and thereby resulting in
poor power output.
•Do not overservice the air cleaner element.
■
•Replace the element once a year or every 6th cleaning.
