Note: See “Maintenance and Care” section for guide bar/saw chain maintenance procedures.

6. For initial setup, install the spiked bumper (F) on the front of

machine with 5x12 mm bolts (E).

7. Mount guide bar on studs (G) and slide toward sprocket (K) to

make saw chain installation easier. Install saw chain around
sprocket and guide bar as shown, with cutters on top of guide
bar facing forward.

8. Install the sprocket guard over the guide bar studs. Ensure

chain tension adjuster pin (J) fits into the guide bar adjuster
hole (H), brake band (N) is positioned around clutch drum (K),
and pin (M) at rear of sprocket guard fits hole (L) on engine
cover. Tighten clutch cover nuts finger tight.

9. Turn saw over, and check brake band (N) for correct position on

clutch drum. If brake band is not in place around drum, remove
sprocket guard, and reinstall. Tighten sprocket guard nuts
finger tight.

10. Adjust saw chain tension, as instructed in “Adjustment, Chain

Tension”.

Improper sprocket guard assembly can result in serious
injury, and will cause severe saw damage if unit is started. Never start or operate saw if brake band
is not in place on clutch drum. Always check chain brake operation after replacing guard. Do not use
saw if chain brake does not function properly.
