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. You can adjust the chain tension by loosening the chain brake nuts and turning the adjusting screw 1/4 of a turn while lifting up on the bar. S If chain is too tight, turn adjusting screw 1/4 turn counterclockwise. S If chain is too loose, turn adjusting screw 1/4 turn clockwise. Adjusting Screw

CHAIN TENSION (Including units with chain already installed) NOTE: When adjusting chain tension,
WARNING: If the saw is operated with a loose chain, the chain could jump off the guide bar and result in serious injury.
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 adjustment 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.
