ATTACHING THE METAL SHIELD
WARNING: The metal shield must be properly installed on the tool anytime the tool is used with a blade. The forward tip of the metal shield helps to reduce the occurrence of blade thrust which can cause serious injury such as amputation to the operator or by- standers. Failure to install the shield in the position shown can result in serious injury to the operator. The length of the shield must be aligned with the length of the shaft.

INSTALLATION OF THE METAL 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 illustrations. These parts must be provided by Poulan/WEED
EATER and installed as shown below. Failure to use proper parts can cause the blade to fly off and seriously hurt you or others.
NOTE: The dust cup and retaining washer are located on the gearbox shaft and not in the parts bag. All other fasteners mentioned in the follow- ing assembly steps are in the parts bag.
1.Remove the retaining washer from the threaded shaft of the gearbox. Leave the dust cup on the shaft.
2.Install the blade and the retaining washer over the threaded shaft.
3.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.
4.Slide the blade and retaining washer onto the shaft of the gearbox.
5.Place the cupped washer onto the shaft. Make sure the cupped side of the washer is toward the blade.
6.Install the blade nut by threading onto the shaft counterclockwise (looking from bot- tom of unit).
