40/50 Hour Maintenance
1. Replace the spark plug with a NGK
BPMR7A (or equivalent), gapped to
0.024" (0.6mm).
2. Extract the fuel filter from inside the
fuel tank, and then remove and
replace the filter element. Before
replacing the filter, inspect the
condition of the fuel line. If damage
or deterioration are noted, the saw
must be removed from service until
it can be inspected by a Shindaiwa-
trained service technician.
Fuel Line
3. Extract the oil filter from inside the
oil tank, and then wash the filter
element in an approved solvent. If
damage or deterioration are noted
on the oil suction line, the saw must
be removed from service until it can
be inspected by a Shindaiwa-trained
service technician.
Spark Arrester Maintenance
Hard starting or a gradual loss of
performance can be caused by
carbon deposits lodged in the
muffler's spark arrester screen. For
maximum performance, the arrester
screen should be periodically re-
moved and cleaned with a small wire
brush.
CAUTION!
Carbon deposits in the combustion
chamber or exhaust port cannot be
removed in the field. For further decar-
bonization, return the 488 to your
Shindaiwa dealer.

Long Term Storage
(over 30 days)
Thoroughly clean the saw exterior.
Remove all chips and other debris
from the cylinder fins and cooling
passages.
Drain the fuel tank, and then clear
the carburetor and lines by run-
ning the saw until it stops from
lack of fuel.
CAUTION!
Never store the saw with any fuel
remaining in the tank, fuel lines, or
carburetor! Your Shindaiwa warranty
does not include coverage for damage
caused by "stale" or contaminated
fuels!
Drain any remaining bar oil from
the oil reservoir.
Remove the spark plug, and then
pour 1/4-oz of 2-cycle engine oil
into the cylinder through the
spark plug hole. Before reinstall-
ing the spark plug, slowly pull the
recoil starter 2-3 times to distrib-
ute the oil over the cylinder walls.
Remove, clean, and reinstall the
air filter element as described
under "daily maintenance."
Repair or replace any damaged
components as required, and then
store the unit in a clean, dry,
dust-free area.
