Poulan Pro PR3816 Instruction Manual page 7

If received assembled, repeat all steps to ensure
your saw is properly assembled and all fasteners
are secure.
1. Check that the chain brake is in the unlocked
position by pulling the front hand guard towards
the front handle.
2. Loosen and remove the bar nuts and the clutch
cover from the saw.
3. Remove the plastic shipping spacer (A) if
present.
4. An adjusting pin and screw is used to adjust
the tension of the chain. It is very important
when assembling the bar that the adjusting pin
located on the adjusting screw aligns into a
hole in the bar. Turning the screw will move the
adjusting pin up and down the screw. Locate
this adjusting pin before you begin mounting
the bar onto the saw. See following illustration.
5. Turn the adjusting screw by hand
counterclockwise until the adjusting pin is
positioned between the indicator marks (B) on
the clutch cover. This should allow the
adjusting pin to be near the correct position.
6. Slide guide bar with chain on bar bolts until
guide bar stops against clutch drum sprocket.
Cutters must face in the direction of rotation.
ASSEMBLY
7. Check that the drive links of the chain fit
correctly on the drive sprocket and that the
chain is in the groove on the bar.
8. Fit the clutch cover and insert the adjusting pin
in the cut-out in the bar.
9. Tighten the bar nut finger-tight.
10. Tension the chain by turning the chain
tensioning screw clockwise using the
combination tool. The chain is correctly
tensioned when it does not sag from the
underside of the bar, but can still be turned
easily by hand.
11. Hold up the bar tip and tighten the bar nuts with
the combination tool.
When fitting a new chain, the chain tension has to
be checked frequently until the chain is run-in.
Check the chain tension regularly. A correctly
tensioned chain ensures good cutting performance
and long life.
