1. Remove the chipper from its shipping crate. Place the unit on a level surface before attempting to assemble it. See
the torque chart in the back of the manual for tightening torque of bolts and screws.
2. Raise the trailer several inches from the ground with a hoist or jack. Support the chipper securely.
3. Lift one wheel to a hub and align the wheel lug holes with the hub lug bolts. Thread the lug nuts (found in the parts
kit) into the holes and tighten the lug nuts to 75 ft. lbs. Follow a star pattern when tightening the lug nuts . Repeat this
step for the remaining wheel.
1. Attach the ball coupler to the hitch weldment using the provided 1/2” x 4” bolts and 1/2” washers and 1/2” nuts. Tighten
to proper torque.
2. Slide the hitch weldment into the hole in the frame, back to the 1/2” mounting holes.
3. Connect the hitch weldment to the frame using the two 1/2” x 4-1/2” bolts, 1/2” washers and 1/2” nuts. Tighten to
proper torque.
4. Check to make sure the tongue jack and safety chains are installed correctly.
1. The chute rotator is connected to the chipper frame first with two 3/8 bolts from the owners kit. Install but do not tighten.
Remove the top cover from the chute rotator to expose the rotator drive sprocket.
2. Attach the discharge chute to the mounting flange on the chipper frame. The square discharge chute will fit over the
round section of the chipper frame.
3. Place the discharge ring, and discharge retainer around the base of the mounting flange on the chipper frame.
4. Attach the discharge ring and retainer to the flange with the provided 3/8” x 1-1/4” bolts and nuts. Tighten to proper
torque.
5. Install the chain around the discharge ring and sprocket on the inside of the chute rotator. Connect chain with the
connector link.
6. Reassemble the top cover and tighten the 4 bolts.
7. Slide the chute rotator assembly back to remove chain slack and tighten the two attachment bolts.
8. torque all fasteners to proper values.
