INSTALLING/REPLACING THE GUIDE BAR AND CHAIN
DANGER: Never start the motor before installing the guide bar,
chain, chain cover and tension knob. Without all these parts in
place, the clutch can fly off or explode, exposing the user to
possible serious injury.
WARNING: To avoid serious personal injury, read and
understand all the safety instructions provided.
WARNING: Before performing any maintenance, make sure
the tool is unplugged from the power supply. Failure to heed
this warning could result in serious personal injury.
CATUION: Always wear gloves when handling the bar and
chain; these components are sharp and may contain burrs,
which can cause serious injury.
WARNING: Never touch or adjust the chain while the motor
is running. The saw chain is very sharp. Always wear
protective gloves when performing maintenance to the chain
to avoid possible serious lacerations.
NOTE: When replacing the guide bar and chain, use only
identical replacement parts.
1. Disconnect the saw from power supply.
2. Loosen the tension knob by turning counterclockwise.
3. Remove the chain cover.(Fig. 7)

4. Remove the bar and chain from the mounting surface.
5. Remove the old chain from the bar.
6. Lay out the new chain in a loop, and straighten any
kinks. The cutters should face in the direction of the
chain rotation. If they face backwards, turn the loop
over.(Fig. 8)

Cutter Direction
7. Place the chain drive links into the bar groove.
NOTE: Make certain of the direction of chain.
8. Position the chain so there is a loop at the back of the bar.
(Fig. 9)
9. Hold the chain in position on the bar and place the loop
around the sprocket.(Fig. 10)
10. Fit the bar flush against the mounting surface so that the bar
stud is in the slot of the bar.
NOTE: When placing the bar on the bar stud, ensure that the
adjusting pin is in the chain tension pin hole.
11. Replace the chain cover.
12. Tighten the tension knob. Remove all slack from the chain by
turning the knob clockwise until the chain seats snugly against

the bar with the drive links in the bar groove. (Fig. 11)
13. When the tension knob is fully tightened, the chain is the
tightest. If the chain is too tight, it will not rotate. To minor adjust
the chain tension, loosen the tension knob by turning it
counter-clockwise slightly until the chain is correctly tensioned.
NOTE: The chain is correctly tensioned when there is no sag on the
underside of the guide bar, then chain is snug, but it can be turned by
hand without binding.
NOTE: A new chain tends to stretch, check chain tension
frequently and tension as required.
14. After a period of usage, the chain may get loose. To tighten the
chain, loosen the tension knob by turning counter-clockwise,
Repeat 12 and 13 to correctly adjust the chain tension.
