CAUTION!

Make sure you do not pierce the fuel line with the end of the hooked wire. The line is delicate and can be damaged easily.

■■Oil filter: 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.

Hard starting or a gradual loss of perfor- mance can be caused by carbon deposits lodged in the muffler’s spark arrester screen.

To service or replace the spark arrester, remove the two cover screws and cover, then remove the screen. Clean the screen with a small wire brush. Replace if damaged. Rein- stall the screen and cover with the arrows directed to the front of the muffler.

the spark arrester cover is installed incorrectly, the hot exhaust gases will be directed into the chain saw and may cause heat damage to sur- rounding parts.

Carbon deposits in the combustion chamber or exhaust port cannot be removed in the field. For decar- bon- ization, return the unit 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 running the saw until it stops from lack of fuel.

■■Drain any remaining bar oil from the oil reservoir.

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!

■■Remove the spark plug, and then pour 1/4 ounces (5 ml) of 2-cycle mixing oil into the cylinder through the spark plug hole. Before reinstalling the spark plug, slowly pull the recoil starter 2-3 times to distribute the oil over the cyl- inder walls.

■■Remove, clean, and reinstall the air fil- ter element as described under “Daily Maintenance.”

■■Repair or replace any damaged compo- nents as required, and then store the unit in a clean, dry, dust-free area.
