with 5/8" x 2" bolts, washers, and nuts. Torque
the bolts to 90 ft. lbs.
3. Connect the safety chains to the adjustable hitch
weldment as shown in figure 10.4. Use a 3/8" x
2-1/2" bolt, washers, and nut to attach the two
safety chains with hooks as shown.

hitch and trailer. Secure the top link pin with a
lynch pin.
Adjust the hitch to make the chipper trailer as level

2.2.2 Attach the Chipper Chute
Do not operate this unit without the chipper
chute correctly installed. Rotating cutting
blades can cause serious personal injury.
Mount the chipper chute to the hydraulic feed using
eight 3/8" x 1" bolts and locknuts. To insert the top
bolts, you may need to temporarily lift the grab roller
with a pry bar. Use three bolts on each side and two
on the bottom (see figure 10.1).
2.2.3 Attach the Chute Extension Tray
1. After mounting the chute to the hydraulic feed,
slide the chute extension tray over the chipper
chute as shown in figure 10.2. Make sure that
you position the lip on the extension tray
behind the lip on the chipper chute. Align the
five bolt holes in the chute extension tray with the
bolt holes in the hinge.
2. Insert five 3/8" x 1" carriage bolts (included in
owner's kit packaged with the chipper) through
the tray and the extension hinge. Secure the bolts
with washers and nuts. Secure with hairpin clips.
2.2.4 Attach the Blower Discharge
Tube
Attach the blower discharge tube to the mounting
flange on the chipper frame (see figure10.3). Half of
the mounting clamp is already attached to the tube.
Slide the tube into the flange and tighten the bolts to
secure it. Install the second half of the clamp to the
tube and flange. Rotate the tube 360 degrees and
lock it in place with the handle to make sure it is
mounted correctly.

2. Fill the engine with oil (per instructions in
supplied engine manual) and fill the fuel tank
