Lay out the new saw chain in a loop and straighten any
kinks. The cutters should face in the direction of chain
rotation. If they face the opposite direction, turn the loop
over.
Place the chain drive links into the bar groove as shown.
NOTE: Make certain of direction of chain.
Position the chain so there is a loop at the back of the
bar.
Hold the chain in position on the bar and place the loop
around the sprocket.
Fit the bar flush against the mounting surface so that the
bar mounts are in the long slot of the bar.
Rotate the chain tension cam clockwise a few turns to
take up enough slack in the chain so it stays in position.
Replace the chain cover.
Rotate chain cover lock knob clockwise to tighten. The
bar should still be free to move for tension adjustment.
Remove all slack from the chain by turning the chain ten-
sion adjustment ring clockwise until the chain seats snugly
against the bar with the drive links in the bar groove.
Lift the tip of the guide bar up to check for sag.
Release the tip of the guide bar and turn the chain ten-
sioning knob 1 click clockwise. Repeat this process until
sag does not exist.
Hold the tip of the guide bar up and tighten the chain
cover lock knob.
The chain is correctly tensioned when there is no sag on the
underside of the guide bar, the chain is snug, but it can be
turned by hand without binding.
NOTE: If chain is too tight, it will not rotate. Loosen the chain
cover lock knob slightly and turn the chain tension adjust-
ment ring 1 click counterclockwise. Lift the tip of the guide
bar up and retighten the chain cover lock knob. Ensure that
the chain will rotate without binding.
ADJUSTING CHAIN TENSION
See Figures 19 - 20.
WARNING:
Shut off the motor, wait for all moving parts to stop, and
make sure the switch trigger is locked out in the off posi-
tion. Never touch or adjust the chain while the engine
is running. The saw chain is very sharp. Always wear
protective gloves when performing maintenance on the
chain. Failure to follow these instructions can result in
serious personal injury.
Proper chain tension is critical to the performance of your
pruning saw. Always check chain tension before using the
saw and periodically until the work is complete.
MAINTENANCE
A cold chain is correctly tensioned when there is no slack on
the underside of the guide bar. The chain should be snug,
but still able to be turned by hand without binding.
A warm chain is correctly tensioned when the flats on the tie
straps hang approximately .050 inches out of the bar groove.
If adjustment is needed:
Loosen the chain cover screw to finger tight.
Raise the tip of the guide bar and continue to hold up
until the end of this procedure.
Turn the chain tensioning knob clockwise until the flats
on the tie straps of the chain contact the bar, making sure
the drive links are seated inside the bar groove.
Retighten the chain cover screw securely.
Release the tip of the guide bar and verify the chain is
now correctly tensioned using the guidelines above.
NOTE: If the chain is too tight and will not rotate, loosen
the chain cover screw slightly, then turn the chain ten-
sioning knob 1 click counterclockwise. Lift up the tip of
the guide bar, retighten the chain cover screw securely,
then verify the chain will now rotate without binding.
NOTE: New chains tend to stretch; check the chain ten-
sion frequently and adjust as needed.
NOTICE:
A chain tensioned while warm may be too tight upon cool-
ing. Check the "cold tension" before next use.
CHAIN MAINTENANCE
See Figures 21 - 22.
Make sure the switch trigger is locked out in the off posi-
tion and the chain has stopped before you do any work
on the saw to avoid accidental starting and possible
serious personal injury.
Use only low-kickback chain on this saw. This fast-cutting
chain will provide kickback reduction when properly
maintained.
For smooth and fast cutting, chain needs to be maintained
properly. The chain requires sharpening when the wood chips
are small and powdery, the chain must be forced through the
wood during cutting, or the chain cuts to one side. During
maintenance of your chain, consider the following:
Improper filing angle of the side plate can increase the
risk of a severe kickback.
Raker (depth gauge) clearance.
Too low increases the potential for kickback.
Not low enough decreases cutting ability.
