2. Remove the bar and chain from the mounting surface
(Fig. 5).
3. Remove the old chain from the bar.
4. Lay out the new saw chain in a loop and straighten
any kinks. THE SHARP SIDE OF THE TEETH MUST
FACE AWAY FROM YOU IN THE DIRECTION OF THE
CHAIN ROTATION INDICATED ON THE GUIDE BAR
. If the teeth face backwards,
turn the loop over (Fig. 6).
5. Starting at the tip, mount the chain drive links into the
bar groove, leaving a loop at the back of the bar. The
chain will loosely t until it is placed on the sprocket
(Figs. 7 – 8).
NOTE: Make certain of the direction of the chain
. If the chain is mounted
backwards, the saw will vibrate abnormally and will not
cut.
6. Hold the chain in position on the bar and place the loop
around the sprocket. Fit the bar ush against the mounting
surface so that the bar stud hole are aligned with the long
slot of the bar (Fig. 9).
7. Replace the chain/sprocket end cover by positioning
the cover onto the saw head. Fit the end cover knob by
inserting the bar stud into the bar stud hole. Tighten the
end cover knob, but leave the bar free to move for tension
adjustment (Fig. 10).
8. Remove all slack from the chain by turning the chain
tensioner ring clockwise until the chain seats snugly
against the bar with the drive links in the bar groove
(Fig. 11).
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. 16.
