Your chipper may arrive totally or partially assembled. Perform the steps in this section
if your chipper arrives partially assembled.
1. Remove the chipper from the shipping crate.
2. Place the unit on a level surface before attempting to assemble it. See the Torque
Chart at the bottom of page 4 for minimum tightening torque of bolts and screws.
3. Raise the trailer several inches from the ground with a hoist or jack. Ensure the
chipper is securely supported.
4. Position the fenders over the axle and secure with eight 3/8 x 1-1/4" bolts and nuts.
5. Align the torsion axle with the mounting brackets on the sides of the chipper trailer.
Secure with four 1/2 x 1-1/4" bolts and nuts.
1. Hold one wheel to a hub and align the wheel lug holes with the hub lug holes (see
figure 1).
2. Thread the lug bolts into the holes and tighten to 75 ft. lbs. Follow a star pattern
when tightening lug bolts.
3. Repeat for the remaining wheel.
1. Insert the adjustable hitch into the hitch channel on the trailer bottom.
2. Insert a 3/8 x 3-1/2" bolt through the bolt hole in the adjustable hitch as shown in
figure 1.
3. Secure with a washer and nut.
2. Place the jack stand on the side of the hitch and secure with the snap pin.
1. Mount the chipper chute to the chipper housing using eight 3/8 x 1-1/2" bolts and
locknuts (see figure 2).
1. Attach the blower discharge tube to the mounting flange on the chipper frame (see
figure 3). Half of the mounting clamp is already attached to the tube.
2. Slide the tube into the flange and tighten the bolts to secure it.
3. Install the second half of the clamp to the tube and flange.
4. Grease the chute to allow free rotation. Rotate the tube 360 degrees and lock it in
place with the handle to make sure it is mounted correctly.
