Long Term Storage - Shindaiwa EC7500 Manuel D'utilisation

Inspection and Maintenance (continued)
Lubricating the Clutch Bearing
Grease the clutch bearing every 20 hours
of operation. Squeezing a grease gun
three times will deliver an appropriate
amount of grease. See Figure 32.
Spark Arrester Maintenance
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(s). Clean the screen
with a small wire brush. Replace if damaged.
Reinstall the screen(s) and cover with the
arrows directed to the front of the muffler.
CAUTION!
When installing the spark arrester
cover make sure the arrows are
directed to the front of the muffler. If
the spark arrester cover is installed
incorrectly, the hot exhaust gases
will be directed into the chain saw
and may cause heat damage to
surrounding parts.
