CHAIN SHARPENING
Chain sharpening requires special
tools. You can purchase sharpening
tools at an authorized service dealer or
go to a professional chain sharpener.
_/L WARNING: Avoid accidental start-
ing. Always unplug saw from power
source before installing a bar and/or
chain.
CHAIN REPLACEMENT
_/L WARNING: Wear protective
gloves when handling chain. The chain
is sharp and can cut you even when it is
not moving.
It is normal for a new chain to stretch dur-
ing the first 15 minutes of operation. You
should recheck your chain tension fre-
quently and adjust the chain tension as
required. See CHECK CHAIN TENSION
section.
Replace the old chain when it becomes
worn or damaged. Use only the Low
Kickback replacement chain specified
in the list of available replacement parts.
The chain must complywith kickback re-
quirements of ANSI B175.1 when tested
with this saw.
See an authorized service dealer to re-
place and sharpen individual cutters on
your chain.
TO REPLACE CHAIN:
1. Disconnect the chain saw from the
power source.
2. Turn the unit upside down on a flat
surface. Straighten out chain, then
lay it on a flat surface.
3, Remove bar mounting nuts, bar
clamp plate, and old chain.
4. Turn the adjusting screw counter-
clockwise to move the adjusting pin
almost as far as it will go to the rear.
Do not remove the adjusting screw
from the unit.
5. Hold chain with cutters facing as
shown.
