2. 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).
2.3.2 Attach Chute Extension Tray
1. After mounting the chute to the chipper frame,
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.
2.3.3 Attach Blower Discharge Tube
1. Attach the blower discharge tube to the mount-
ing flange on the chipper frame (see figure 10.3).
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.
2.3.4 Connect the PTO Shaft
1. Connect the PTO Shaft female end to the rotor
shaft using key stock and two set screws con-
tained in the owner's kit.
2. Connect the opposite end of the PTO shaft to the
tractor.
2.3.5 Before using
Check all screws, bolts and nuts for tightness. See
torque chart on page pg 7 for proper tightening
torque.
Important! See instructions for hydrostatic pump
start-up procedure, at right.
2.4 All Models
2.4.1 Connect the Hydrostatic Control
Cable
1. Remove the clevis assembly from the hydrostatic
control cable end (see figure 10.5). Remove one
nut on the cable end. Insert the cable end into the
hole in the cable anchor weldment. Replace the
nut and the clevis assembly.
2. Attach the clevis assembly to the center hole on
the feed control lever.
3. Adjust the cable detent ball to hold the control
arm is in the forward position or neutral position
detents.
Important! See section below for hydrostatic
pump start-up procedure
2.4.2 Hydraulic Fluids
Handle pressurized hydraulic fluid carefully. Escap-
ing pressurized hydraulic fluid can have sufficient
force to penetrate your skin causing serious injury.
This fluid may also be hot enough to burn. Serious
infection or reactions can develop if proper medical
treatment is not administered immediately.
Premium hydraulic fluids containing high quality
rust, oxidation, and foam inhibitors are required.
These include premium turbine oils, API CD
engine oils per SAE J183, M2C33F or G
automatic transmission fluids meeting Allison C-3
or Caterpillar TO-2, and certain specialty
agricultural tractor fluids.
2.4.3 Prepare Hydraulic System
Follow this start-up procedure when starting a new
installation or when restarting an installation in
which the hydrostatic pump has been removed from
the system.
The flow from the reservoir to the hydrostatic pump
and the flow returning from the hydrostatic pump are
always the same. Hydraulic fluid can flow either
direction between the hydrostatic pump, crossover
relief valve, and motor. Refer to page 10.6 for the
hydraulic Schematic.
