Loop
6. Mount the guide bar by inserting the stud bolt into the
long slot on the guide bar; arrange the chain loop on the
back of the bar to ensure the sprocket is inserted in the
loop (Fig. 24).

7. Adjust the chain tension by pulling the guide bar + chain
forward, and make sure the chain is fully stretched. Using
your other hand, Fit the chain/sprocket end cover back on
by inserting the small tab located on the right bottom of
the end cover into the hole on the machine body. Turn the
end cover + chain tensioning knob clockwise until you find
the right chain tension (Figs. 25 – 26).

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.
NOTE: If the chain is too tight, it will not rotate. Loosen
the end cover + chain tensioning knob slightly by 1/4 turn
counterclockwise. Ensure that the chain can be rotated
by hand without binding. Do not loosen the end cover +
chain tensioning knob too much otherwise the chain + bar
assembly will come loose.
NOTE: A new chain tends to stretch; check the chain
tension frequently, and adjust tension as required.
Chain Tension
Guide bar
Check the chain tension before using the saw when the chain
is cold. The correct tension of a cold chain is when there is no
slack on the underside of the guide bar; the chain is snug, but
you can rotate it by hand without binding.
Stud bolt
During normal saw operation, the temperature of the chain
will increase. The drive links of a correctly tensioned warm
chain will hang approximately 0.050 in. (1.25 mm) out of the
bar groove (Fig. 27). Be aware that a chain tensioned while
warm, may be too tight upon cooling. Check the "cold tension"
before next use. The chain must be re-tensioned whenever the
flats on the drive links hang out of the bar groove (Fig. 27).
