Installation Tips

• Always disconnect the power source (unplug or remove battery/spark plug) before servicing the chain.
• Wear protective gloves during installation.
• Clean the guide bar groove and oil holes before seating the new chain.
• Ensure cutters face forward in the direction of rotation on the top of the bar.
• Properly tension the chain according to your saw's manual; it should be snug but still pull freely by hand.
