5.1 SHARPENING CHIPPER BLADES

When the Chipper Blades dull, chipping becomes difficult. It is recommended that the chipper blades are sharpened every 5-15 hours of chipper operation.

The Chipper Blades are two edged. When the first edge dulls, flip the blade to use the sharp second edge. After both edges are dull, sharpen the chipper blades.

Follow the procedure below to remove the chipping blades for sharpening:

WARNING

Before inspecting or servicing any part of the machine, shut off the power source, disconnect the spark plug wire from the spark plug, and make sure all moving parts have come to a complete stop. The chipping blades are sharp! Use care when working on machine to avoid injury.

1.Remove the two 3/8 inch retaining bolts holding the ac- cess cover to main frame assembly.

2.Tilt access cover over to allow rotor access. Rotate the

WARNING

The rotor assembly has a lock mechanism. When working on the rotor assembly, use the lock mechanism at all times. Remove plastic bearing cover under chipper chute.

rotor so that the bolts holding the chipper blades are most accessible (See Fig. #6).

3.Remove the two hex head bolts holding the blade itself. Repeat for all four blades. The four chipping blades have two edges per blade and can be reversed one time each before sharpening. Reinstall chipping blades and pro- ceed with chipping.

4.If already reversed, the chipping blades will have to be ground to a 45 degree angle. Be careful when grinding so that the blade material does not get too hot and change color–this will remove the blade's special heat treated properties. Use short grinding times and cool with water. Try to remove an equal amount off each blade to maintain balance.

5.Replace the chipping blades and tighten bolts to 75 ft. lbs.
