    All parts of trigger were missing.

    Kurt - May 8, 2022
    Tool Type

    Chain Saw

    Difficulty

    Medium

    Time

    15-30 minutes

    Tools Used

    , Small hammer

    First snap the trigger into place and use a small hammer to drive the pin in. It took me the most time to figure out how the spring goes in. The end with the circular part pushes into the hollow in the back of the trigger. After that, the long trigger lock just gets pushed down into the handle until it snaps in. I had nothing to go on but, it was easy once I figured it out.

    The handle was broken along with the throttle mehanism

    Randall - March 2, 2017
    Removed the old handle half that was left and the right side that is attached to the upper handle . Removed the torsion mount springs and the air filter housing . Transferred all the necessary parts then installed the new right half with the upper handle and then the throttle lock and trigger with the return spring which was slightly confusing when the old parts were missing so I used the parts breakdown from e replacement for the placement and finished assembling the rest and the repair was successful thank you, all the part were right the first time around
