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
