ASSEMBLY

•

Move the lever to its rear, lower position. Push in the
spring on the chain tensioner handle and turn the bar nut
clockwise by hand.

•

Release the spring. Hold the bar upwards as you move
the handle forward. Note that the arm's mechanical stop
shall not be reached. The stop prevents the arm from
pointing forwards and prevents cutting.
