MAINTENANCE
REPLACING THE BAR AND CHAIN
• Remove the chain cover.
• The bar contains a bar stud slot that fits over the bar stud. The bar also contains a chain
tensioning pin hole that fits over the chain tensioning pin.
• Place the bar onto the bar stud so that the chain tensioning pin fits into the chain tensioning
pin hole. Fit the chain over the sprocket and into the bar groove. The cutters on the top of
the bar should face toward the bar tip, in the direction of the chain rotation.
• Replace the chain cover.
• Remove all slack from chain by turning the chain tensioning bolt clockwise, assuring that
the chain seats into the bar groove during tensioning.
• Lift the tip of the bar up to check for sag. Release the tip of the bar, and turn the chain
tensioning bolt 1/2 turn clockwise.
• Repeat this process until the sag no longer exists.
• Hold the tip of the bar up and tighten the locked bolt securely.
• The chain is correctly tensioned when there is no slack on the underside of the bar, the
chain is snug, and it can be turned by hand without binding.
