ening the trimmer head. Remove the trimmer head by turning clockwise. Remove the screw- driver. See INSTALLATION OF THE CUTTING HEAD for illustrations. Be sure to store all parts and instructions for future use. Never use the trimmer head with the metal blade installed.
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 McCulloch 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 is located on the gearbox shaft and not in the parts bag. All other fasten- ers mentioned in the following assembly steps are in the parts bag.
1.Install the blade and the retaining washer over the threaded shaft.
2.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.
3.Slide the blade and retaining washer onto the shaft of the gearbox.
4.Place the cupped washer onto the shaft. Make sure the cupped side of the washer is toward the blade.
5.Install the blade nut by threading onto the shaft counterclockwise.
NOTE: Make sure all parts are in place as il- lustrated, 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.
6.Align hole in dust cup with hole in side of gearbox by rotating the blade.
7.Insert a small screwdriver into aligned holes. This will keep the shaft from turning while tightening the blade nut.
8.Tighten blade nut firmly with a wrench (pro- vided) 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.
NOTE: To remove blade, insert screwdriver into aligned holes. Unthread the nut and remove parts. Be sure to store parts and instructions for future use.
ATTACHING THE TRANSPORT GUARD
NOTE: The transport guard must always be attached to the blade when the machine is be- ing transported or in storage.
1.Remove ends of wire retainer from the clips on the transport guard.
2.Lift wire retainer and position blade in transport guard.
3.Place wire retainer over blade and insert both ends of wire retainer back into clips.
