BLADE REPLACEMENT
WARNING: The blade will continue to spin after the engine stops or after the throttle trigger has been released. To avoid serious injury, make sure the blade has stopped coasting and disconnect the spark plug before performing work on the blade.
WARNING: Wear protective gloves when handling or performing maintenance on the blade to avoid injury. The blade is sharp and can cut you even when it is not moving.
WARNING: Do not use any blades, or fastening hardware other than the washers and nuts shown in the following illustration. These parts must be provided by Poulan PRO and installed as shown. Failure to use proper parts can cause the blade to fly off and seriously hurt you or others.
1.To remove the blade, align hole in the dust cup with the hole in the side of the gear- box by rotating the blade.
2.Insert a small screwdriver into aligned holes. This will keep the shaft from turn- ing while loosening the blade nut.
3.While holding the screwdriver in position, remove blade nut by turning clockwise as you are facing the nut.
4.Remove both washers and the blade from the blade shaft. Leave the dust cup on the gearbox.
5.Install new blade and retaining washer onto the threaded shaft extending from the gear- box (blade must be between the dust cup and the retaining washer). Make sure the raised part of the retaining washer is facing the gearbox, and the raised area fits into the hole in the center of the blade.

7. Install blade nut by threading onto the shaft counterclockwise as you are facing the nut.
NOTE: Make sure all parts are in place as illus- trated, and the blade is sandwiched between the dust cup and the retaining washer. There should be no space between the blade and the dust cup or the retaining washer.
8.Tighten blade nut firmly with a wrench while holding screwdriver in position.
9.Remove the screwdriver.
10.Turn blade by hand. If the blade binds against the shield, or appears to be un- even, the blade is not centered, and you must reinstall.
