THROTTLE CONTROL OPERATING INSTRUCTIONS
Your new engine throttle control
(see Fig. 4) has three positions in-
dicated on the control body:
FAST, SLOW, and STOP.
•When starting the engine, place
the lever at the FAST setting.
•Use the settings between FAST
and SLOW to regulate the engine
speeds. For heavy duty chipping
and shredding, you will want to
use the FAST setting. For light
duty chipping and shredding, or for
transporting your machine, you
may want to use aslower engine
speed. Doing so will result in re-
duced noise volume and gasoline
consumption.
•Move the lever all the way
back to STOP to shut offthe
engine. Remove any hearing pro-
tection and listen
to the sound of
the machine as it slows down.
There is an audible tone that
changes
as the cutting blades slow
down. Listen for all parts
to come
to acomplete stop.
IMPORTANT: Refer to Page 26
of your Manual for complete
"Starting and Stopping the
Engine" instructions. Your new
throttle control replaces the
On/Off Switch described on that
page.

spond to various throttle lever set-
tings' then the following adjust-
ments may be necessary.
DANGER
To prevent personal injury,

free to move in the Cable Clamp
(do not remove the screw).
4. Push the Throttle Cable up until
the Control Lever touches the High
Speed Stop tab.
5. Hold the Control Lever at this
position and securely tighten the
Cable Clamp Screw.
6. Test the function
of the throttle
control by moving it back and
forth between the FAST and STOP
positions.

Assembly
STEP 2: Install the Handlebars
A. Protect the handlebars from
being scratched during assembly
by placing cardboard or padding
on the ground behind the two
large
wheels on the machine.
B. With the curved end
of the han-
dlebars facing up, place the two
handlebar ends on the inside
of the
handlebar mounting brackets (A,
Inset #1, Figure 2-2). On the 5HP
model, be careful not to severely
bend the gear shift lever cable at-
tached to the left side handlebar.
C. Loosely install a5/16"-18 x
5/8" flange lock hex head screw
(B, Inset #1, Figure 2-2) through
the lower holes in each handlebar
and mounting bracket.
D. The handlebars are adjustable
to one
of three operating positions:
High,
Medium and Low. There is
E 0

Inset #2
also a Storage position which
places the handlebars upright.
Refer to Inset #2, Figure 2-2 to
identify the bracket holes that are
used for the various positions.
E. Lift the handlebars and align one
of the two holes in each handlebar
with the selected hole in each
bracket. Insert 5/16"-18 x
2" curved
head screws (C, Inset #2) through
the handlebars and brackets.
F. Insall astar lock washer (D) on
each screw.
G. Add a5/16"-18 knob (E) on
each screw and tighten securely.
F. With a1/2" wrench, securely
tighten the two screws (B, Inset #1)
in the handlebar ends.
STEP 3: Install the
Engine ON/OFF Switch
A. The engine ON/OFF switch
assembly (A, Figure 2-3) is con-
nected to along wire that leads
from the back
of the engine.
B. Run the wire
up the inside
edge
of the right side handlebar.
C. With a5/16" wrench, attach
the switch bracket with two #10-
24 x1/2" self-threading
hex/washer head screws (B,
Figure 2-3).
D. Secure the switch wire to the
handlebar with two cable ties (G,
Figure 2-2). Leave the ties alittle
loose to allow the wire to "stretch"
if the handlebars are later placed
in the storage position. Trim off
any excess tie length with scissors.
Figure 2-3: Install Engine ON/OFF
Switch.
STEP 4: Attach the Gear Shift
Lever Cable (5HP Model Only)
The GEAR SHIFf LEVER (F,
Figure 2-2) is attached to the left
side handlebar. The cable leading
from the lever must be connected
to the transaxle (transmission) in-
side the mainframe.
IMPORTANT: Do not severely
bend or kink the cable as dam-
age to the cable will result.

A. With a3/8" wrench, remove the
three self-threading screws from
the transaxle access cover (A,
Figure 2-4) located on the rear of
the mainframe. Remove the cover.
B. Move the GEAR SHIFT
LEVER (F, Figure 2-2) to the No.
4setting as indicated on the decal
(push lever all the way forward
until it stops moving).
C. With a3/8" wrench, loosen the
cable clamp screw (B, Figure 2-4)
and swing the cable clamp
(C) to
one side.
IMPORTANT: The transaxle
shifting arm (D, Figure 2·4) is
preset in 4th gear. Do not move
the shifting arm before installing
the cable.
D. Gently route the cable (E,
Figure 2-4) below the handlebar
and insert the "Z" hook end
of the
cable wire into the top
of the
transaxle shifting arm (D).
E. Place the cable sheath in the
groove on the top
of the transaxle
and swing the clamp over the
cable. Check that the GEAR
SHIFT LEVER (on handlebar) is
still in the
No.4 setting. Then,
tighten the clamp screw securely.
F. Check the function of the cable
by moving the GEAR SHIFT
LEVER all the way back to P
(Park) and then all the way forward
to
No.4. You should feel the lever
engage seven distinct positions
(with six "clicks" in between).
If
not, repeat Steps Bthrough F.
NOTE: Be sure that the cable
sheath does not move within the
clamp while performing this test.

is connected to the
bracket on the rear, left side of the
mainframe. Run the cable
up the
inside edge of the left side handle-
bar and align the hole
in the cable
clamp (B) with the
upper of the
two holes that are located afew
inches below the GEAR SHIFT
LEVER.
B. Insert a1/4"-20 x1-5/8" curved
head screw (C, Figure 2-5)
through the handlebar and into the
clamp. Add a1/4"-20 flanged
locknut (D) and tighten securely
using a7/16" wrench.
C. Slip the cable eyelet (E, Figure
2-5) over the stud (F) on the wheel
drive bail. Place awood block be-
hind the stud and use ahammer
to
tap the cap push nut (G) onto the
stud (the push nut can also be
pressed on with apair
of large-
sized pump or parallel jaw pliers).
D. Secure the gear shift lever
cable and the wheel drive bail
cable to the handlebar with two
cable ties (H, Figure 2-2). Leave

STEP 6: Install the Chipper Chute
A. In the following steps, do not
touch the chipper cutting blade (A,
Figure 2-6) that is located inside
the chute mounting hole (the blade
may not be visible due to its ship-
ping position on the rotor assem-
bly.) The blade
is very sharp and
can cause personal injury.
B. For shipping purposes, two hex
head screws are installed in the
holes labeled
No.1 and 4in Figure
2-6. With a1/2" wrench, remove
the two screws and throw them
away. They
are not for reuse on
the machine.
C. With the long end
of the chip-
per chute mounting flange (B)
pointing down, tilt the top of the
chute slightly away from the
machine and slide the chute lip (C)
into the chute mounting hole. It
may
be easier if someone helps
support the chute while you install
the four screws.
D. On the 5HP model, twist the
chute
in aclockwise direction until
the bottom left corner
of the
mounting flange fits into the nar-
row slot between the engine body
and the machine housing.
E. On all models, align the four
holes
in the mounting flange with
the four holes
in the machine hous-
ing. Using your fingers, loosely
install four 5/16"-18 x5/8" flange
lock hex head screws (D), follow-
ing the numbered sequence shown
in Figure 2-6. After all four
screws are in place, tighten them
securely with a1/2" wrench.
F. Look inside the top of the chute
and check that the rubber retainer
flap
is hanging freely inside the
chute.
NOTE: Ahinged, chute extension
is attached to the top
of the chipper
chute. The chute extension
is
shipped from the factory in its
folded, storage/light-duty chipping
position.
To unfold the screen for
heavy-duty chipping, refer to the
instructions found on Page 30.
DANGER
Do not operate the machine
unless the chipper chute is
securely installed. Serious
personal injury can result
from contact with rotating
cutting blades if the chipper
chute is not securely in-
stalled.
