3. An adjusting pin and screw is used to ad-
just the tension of the chain. It is very im-
portant when assembling the bar, that the
pin located on the adjusting screw aligns
into a hole in the bar. Turning the screw will
move the adjustment pin up and down the
screw. Locate this adjustment before you
begin mounting the bar onto the saw. See
illustration below.

4. Turn the adjusting screw by hand counter-
clockwise until the adjusting pin just
touches the stop. This should allow the pin
to be near the correct position. Further ad-
justment may be necessary as you mount
the bar.
5. Slide guide bar behind clutch drum until
guide bar stops against clutch drum
sprocket.
Mount the bar
6. Prepare the chain by checking the proper
direction. Without following the illustration it
is easy to place the chain on the saw in the
wrong direction. Use the illustration of the
chain to determine the proper direction.

7. Place the chain over and behind the
clutch, fitting the drive links in the clutch
drum sprocket.
Place chain onto the sprocket
8. Fit bottom of drive links between the
teeth in the sprocket in the nose of the
guide bar.
9. Fit chain drive links in bar groove.
10. Pull the bar forward until the chain is
snug in the guide bar groove. Ensure all
drive links are in the bar groove.
11. Now, install chain brake making sure the
adjusting pin is positioned in the lower
hole in the guide bar. Remember this pin
moves the bar forward and backward as
the screw is turned.
12. Install chain brake nuts and finger tighten
only. Once the chain is tensioned, you
will need to tighten chain brake nuts.
CHAIN TENSION (Including units with
chain already installed)
NOTE: When adjusting chain tension,
make sure the chain brake nuts are finger
tight only. Attempting to tension the chain
when the chain brake nuts are tight can
cause damage.
Checking the tension:
Use the screwdriver end of the chain adjust-
ment tool (bar tool) to move the chain around
the bar. If the chain does not rotate, it is too
tight. If too loose, the chain will sag below the
bar.

Adjusting the tension:
Chain tension is very important. Chain
stretches during use. This is especially true
during the first few times you use your saw.
Always check chain tension each time
before you start the chain saw.
You can adjust the chain tension by
loosening the chain brake nuts and turning
the adjusting screw 1/4 of a turn while lifting
up on the bar.
