6. Replace the side cover, turn the chain tension adjustment screw clockwise until the chain is properly tensioned. The
guide bar must then be pushed upwards and check chain tension again. Do not tension the chain too tight.
7. After the chain is well-tensioned, tighten the nut again.
8. Once the chain is well tensioned, tighten the side cover lock nuts. Start with a new chain, allowing it to run-in for 2-3
minutes.
NOTE: If the chain is too tight, it will not rotate. Loosen the chain cover lock nuts slightly and turn the chain adjustment
screw 1/4 turn counterclockwise. Lift the tip of the guide bar up and retighten the chain cover lock nuts. Ensure that the
chain will rotate without binding.
