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 you use and refuel your saw.
An adjusting screw (located on the guide bar) is used to adjust the tension of the chain (see illustration).
SLoosen the chain brake nuts.
STurn adjusting screw clockwise until chain solidly contacts bottom of guide bar rail.
