1. Chain tensioning screw
Adjust the chain tension until the chain touches
the bottom edge of the guide bar, then pull the
chain away from the bottom edge of the guide
bar; a properly adjusted chain can only be pulled
3.2 to 6.4 mm (1/8 to 1/4 inch) away from the
guide bar, and snaps back on release.
Note:
While adjusting the chain tension, lift up
the tip of the guide bar with a gloved hand to
ensure the guide bar does not sag and affect
chain tension.
6. Use a gloved hand to pull the chain around the
guide bar. A properly tensioned chain should
move smoothly and remain in contact with the
bottom edge of the guide bar.
7. If the chain is not properly tensioned, repeat
steps 4 through 7.
