8. Adjust the chain tension as needed by adjusting the
chain tensioner screw with the supplied at-tip blade
screwdriver. Make sure to align the chain tensioner screw
with the pin hole (Fig. 8).
9. Replace the chain/sprocket end cover by inserting the rear
tab rst into the rear tab slot and position the cover onto
the saw head. Tighten the end cover nut, but leave the bar
free to move for tension adjustment (Fig. 9).
10. Remove all slack from the chain by turning the chain
tensioner screw clockwise until the chain seats snugly
against the bar with the drive links in the bar groove
(Fig. 10).
NOTE: The chain is correctly tensioned when there is no
sag on the underside of the guide bar; the chain is snug,
but can be rotated by hand without binding. For more
information on chain tensioning, see the maintenance
section beginning on pg. 18.
11. Tighten the end cover nut completely using the hex key
wrench. (Fig. 11).
NOTE: If the chain is too tight, it will not rotate. Loosen
the end cover nut slightly and turn the chain tensioner
1/4 turn counterclockwise. Lift the tip of the guide bar up
and retighten the end cover nut. Ensure that the chain can
be rotated by hand without binding.
NOTE: A new chain tends to stretch; check the chain
tension frequently, and adjust tension as required.
Preparing To Work
Chain Lubricant
mCAUTION!
• Before starting the saw, remove the oil tank cap and
add bar and chain oil to the top of the oil level window
(Fig. 12). One minute of use will consume approximately
0.15 oz (5 ml) of oil. Rell when the oil level drops to 1/4
of a tank.
