properly tensioned. The guide bar must then be pushed upwards and check chain tension

8. Once the chain is well tensioned, tighten the side cover lock nuts. Start with a new chain,

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.
