Adjusting the Tension (Pic. 8, 9 & 10)
Chain tension is very important. Chains stretch during use. This
is especially true during the first few times you use your saw.
Always check chain tension each time you use and refuel your
saw.
1. Loosen bar nuts until they are finger tight against the clutch
cover.
2. Turn adjusting screw clockwise until chain solidly contacts
bottom of guide bar rail.
3. Using bar tool, roll chain around guide bar to ensure all links
are in bar groove.
4. Lift up tip of guide bar to check for sag. Release tip of guide
bar, then turn adjusting screw 1/4 turn clockwise. Repeat
until sag does not exist.
5. While lifting tip of guide bar, tighten bar nuts securely with
the bar tool.
6. Use the screwdriver end of the bar tool to move chain
around guide bar.
7. If chain does not rotate, it is too tight. Slightly loosen bar
nuts and loosen chain by turning the adjusting screw 1/4
turn counterclockwise. Retighten clutch cover locking nuts.
8. If chain is too loose, it will sag below the guide bar. DO NOT
operate the saw if the chain is loose.
