3. Chipper
The chipper disc is on a sh aft in common with the
shredder/grinder, rotating
at 3600 RPM, and contains the
chipper knife. The rotating knife is separated from the
stationary anvil
by a gap of 1/ 16 to 1/8 inch.
Limbs
are fed through the chipper chute which directs
the limb between the knife and the anvil, shea
ring chips
from the limb.
The chips discharge through the samescreen
perfo~ations
as the shredder/grinder.
4. Power transmission (See Photo 11)
A centrifugal clutch is mounted on the engine shaft and
is disengaged for easy s
tarting . After the engine sta rts the
RPM automatically increases, and rotates the clutch.
At
approximately 1800 RPM the clutch starts engaging and
is fully engaged at 2500 RPM and above. The engine will
continue
to increase until 3600 RPM, controlled by the
governor.
The V-belt transfers the power from the clutch to the
chipper/
shredder/grinder shaft through the pulley.

Operating Instructions
Now th at yo u are famili ar with the components an d h ow
they work. use that knowledge and the fo ll ow in g information
to lea
rn how to operate you r chipper/shredder/grinder
efficiently and safely.
1. Malerials suitable for the chipper
Limbs, branches, vines, lumber, s in gularly or in
multipl es. Usually larger than 1/2" w hi ch wi ll easily go
t hr ough the 3" chipper chute. (Remove nai ls and/ or metal
parts from old lumber.)
2. Malerials suitable for the shredder/grinder
Limbs, branches, twigs, leaves, manure, garbage, grass,
sta lk s. brush. vines. so d or soil. wood chips. hay and straw.
lumber. paper and cardboard. compost. and other misc.
materials (genera
ll y li mbs. lumber etc. are 1/2" dia meter
or sma
ll er).
3. Sile selection
The Renegade 250 may be pushed or pulled by the handle.
"Stop" the engine before moving.
Loc ate the un it on level ground (dirt or grass preferred).

to the material to be processed. Stand to one side
of the hopper(s)
so that no part of the body is in line with
the hopper(s) when feeding or reach
in g for material.
Pre-operational checklist
1. Service engine
2. Select level site (preferably dirt or grass)
3. Put on goggles and wo rk gloves
4. Visua ll y check hopp ers to be free of obstructi on
5. Start your engin e!
Engine starting (See Engine Manual .)
4. How 10 use Ihe chipper
Li m bs or branches wi th large stubs or fo rk s will have
to be trimmed. however. smaller limbs with multiple
( Pftoto 12) Stand to one side. hold branch tinnly . teed in smoothly . 8
branches will be squeezed together and guided by the co ne
shape as they
are pushed into the chipper chute. (See photo
1
2.) Push them in as rapidly as the ch ipper will cut them
without slowing the engine down
to a po int where it labors
or the clutch tends to slip (and/or disengag e. appr ox. 2500
RPM). (Refer to Section V·2 . Ma in tenance.) When the
material
is reduced to the le ngth 01 the chipper chute (See
pho to 13 ). pull it out and feed into the shredder /g rinder
hopp
er . (See photo 14 and Secti on IV·5.)
(Photo 13) Stand to one side, do not force short material into ch ipper
chute
by hand , feed into shredder hopper.
(Photo 14) Stand to one side, feed material into shredder hopper
crosswise as shown.

A WARNING: Never
put your hands into the chipper
chute. Short branch stubs may be pushed through
the chipper
with the next branch.
Helpful hints
• Rotate large limbs as cutting occurs.
• Several smaller limbs may be held together.
• Keep the branch away from your body.
5. How to use the shredder/grinder
Material may be put into the hopper from any of the four
sides.
AWARNING: The
grinder has a tendency to pull
long material,
or large bundles of stringy materials,
outof
yo ur hands, so don't hold on tightly. If material
does not feed itself,
do not use your hands to force
material down the hopper through the split
rubber
fe nce. Use a stick that will grind up if it comes
in contact with the cutting area. (See photo 15.)
( Photo 15) Use a stick to push material through the rubber fence, If
H js not feeding by itseH. Feed at an even rate.
Loose material(leaves, grass,etc.) maybe dumped directly
into the hopper. Use a stick and push small amounts through
the
rubber flap at a steady, even rate. (See photo 15.) Do
not overfeed so that the chamber is too full. This will slow
the engine down
to a point where it labors roughly or the
cl utch tends to slip (and/or disengage, approx. 2500 RPM).
(Refer to Section
V-2 -Maintenance.)
NOTE: Occasionally, when grinding wet or green
material, a buildup will occur on the discharge screen,
g rinding dry material will usually clear the screen. The
practice of alternating green or wet material with dry
m ater ial will keep the unit clean and clear.
Thesize of the perforations in thedischarge screen largely
determinethe fineness of thefinished material. The
standard
sc reen installed in the machine has %" holes. This screen 9
OPERATING INSTRUCTIONS
is generally best for making compost. Screens with smaller
holes are available, which work well for grinding grain into
livestock feed or such things as fine ground potting soil.
Wet, gummy materials will clog the %" and finer screens.
A larger 1 ~" optional screen will handle this type of
material, producing a coarser ground compost. The optional
grinding screen sizes available have W', X", %", 72" and l~fI
perforations.
6. Installing and shredding with rods and rollers
A still coarser cut compost and the recommended way
to handle wet and heavy materials is to use the rods and
rollers supplied as optional equipment for the machine.
To install the rods and rollers, remove the rod retainer
plate. (See photo 16.) Pull the two screen rods out from the
mountingholes. (See photo 17.) Remove the dischargescreen
(Photo 16)
(Photo 17)

OPERATING INSTRUCTIONS
and you are ready to install the rods and rollers. Always
use rollers with the rods when screen
is not installed. Slide
a roller on each of the five rods and insert in proper holes.
(See photo 18.) Reinstall rod retainer plateand you are ready
to operate.
(Photo 18)
If the materials are still too wet and gummy, remove some
of the rods and rollers
start ing at the back of the chambe r.
Always thoroughly clean grinding chamber after grinding
wet materials.
7. Installing screen
To reinstall the screen, remove all the rods and rollers,
insert screen up from underneath until it is in slot and
againstscreen stopswelded in frame. Forproperfitofscreen
make sure slot
and screen stops are clear of debris. (See
photo 19 .) Insert two of the screen rods through holes. (See
photo 17.) Do not put rollers on rods when using screen
10
or use more than two rods as this will block screen
perforations. Replace rod retainer plate.
(Photo 19) Make sure screen slot and stops are free of debris.
Helpful hints
• Move the unitperiodically to keep thedischarged material
from blockingthedischargescreen. Pushdown
on thehandle
liftingthefrontstand
clear of the discharged pile of material
and pull backwardsapprox.18" and letthe front
sta nd down
level behind the di
sc harged pile of material.
• A wide (48" to 60"), long piece of plastic laid down prior
to sta rting under the discharge area will keep lawns clean
and is an easy way
to pick up the discharged material.
• A 55-gallon plastic bag may also be used. The bag must
be placed with the opening under the discharge and the
remainder of the
bag stretched out through the frontstand.
Move the material toward the bottom'of the bag as required.
