Poulan makes the Weed Trimmer edger, a handy tool that saves you time when you need to trim around sidewalks and other areas. The edger is only as good as the blade you are using. Removing a Weed Trimmer edger blade for inspection or replacement is a straightforward process. It is a good idea to put on a pair of leather work gloves to protect your hands when working with the edger blade.
Grab the end of the spark plug wire where it connects to the top of the spark plug. Twist the end to the right and pull the spark plug wire away from the spark plug.
Locate the spindle locking lever at the bottom of the gear case near the edger blade. Push the lever into the gear case with one hand, and rotate the edger blade with your other hand. The lever will fall into a groove and lock the blade as you rotate the blade.
Hold the locking lever with one hand. Remove the blade locking nut with a socket wrench with your free hand. The locking nut is what secures the blade to the spindle.
Release the locking lever. Remove the two washers from the spindle. Free the edger blade by pulling it way from the spindle.
