(Pre-filter) Remove the air cleaner
element from the carburetor and
wash it with soap and water. Rinse
the element thoroughly with clean
water. Squeeze out the water and
allow the element to dry before
reinstalling.
(Dry type filter) Inspect the filter. If
the element is damaged or dis-
torted, replace it with a new one.
The 488P uses a high capacity dry-type
air filter element. The filter should not be
cleaned with a liquid cleaner and must
NEVER be oiled.
Direct the air stream only at the inside
face of the filter.
Gently, tap filter on a hard surface
to dislodge debris from element or
use compressed air to blow debris
from the air filter element.
Working in reverse order of disas-
sembly reassemble the air filter
elements and cover to the saw.

CAUTION!
Never allow chips or other debris
to enter the cylinder bore! Before
removing the spark plug, thor-
oughly clean the spark plug and

Carefully inspect the drive sprocket
for wear or damage, and replace if
noted. Inspect the guide bar grooves

daily. When these chains are worn out,
replace both the chains and drive
sprocket at the same time.
