Platinum-tipped spark plugsIt is not necessary to replace the platinum-tipped
spark plugs as frequently as the conventional
type spark plugs since they will last much longer.
Follow the maintenance schedule but, do not
reuse them by cleaning or regapping.
Always replace with recommended
platinum-tipped spark plugs.To remove the filter from the air cleaner, pull off
the lock pins
1
and pull the unit upward
2.
The filter element should not be cleaned and
reused. Replace it according to the maintenance
log shown in the Service and Maintenance
Guide. When replacing the filter, wipe the inside
of the air cleaner housing and the cover with a
damp cloth.
WARNING

Operating the engine with the air
cleaner removed can cause you orothers to be burned. The air cleaner
not only cleans the air, it stops flame
if the engine backfires. If it is not
there, and the engine backfires, you
could be burned. Do not drive with
the air cleaner removed and be care-
ful when working on the engine with
the air cleaner removed.

Never pour fuel into the throttle body
or attempt to start the engine with
the air cleaner removed. Doing so
could result in serious injury.
