ASSEMBLY AND SERVICE
WARNING: DO NOT OPERATE THIS EQUIPMENT
UNTIL YOU HAVE READ AND UNDERSTOOD YOUR
OWNER/OPERATOR MANUAL AND FILLED OUT YOUR
WARRANTY REGISTRATION CARD.
THIS SYMBOL MEANS WARNING OR CAUTION.
PERSONAL INJURY AND, OR PROPERTY DAMAGE
MAY OCCUR IF INSTRUCTIONS ARE NOT FOLLOWED
CAREFULLY.
Your Chipper/Shredder comes assembled (except for the
hopper parts which are separate so it could be shipped more
compactly). The engine, wheels and all major components are
assembled. You will not be attaching any moving parts. You
will be attaching the top hopper, chipper cone and discharge
deflector. This assembly requires little mechanical ability and
should take approximately 30 minutes.
What You'll Need:
Absolutely Necessary:
▲ Scissors or knife (to cut packing straps & tape)
▲
#2 Phillips screwdriver (The right size screwdriver helps
prevent stripping the screw heads!)
7/16" socket or box end wrench
▲
1/2" socket or box end wrench
▲
Hammer (plastic mallet or ball-peen hammer is best)
▲
B
1. Unwrap all parts and count all pieces to be certain you have
everything you need. If not, call your dealer to supply you
with any missing parts. Place loose nuts and bolts in the top
of a small box or another container to make sure you don’t
lose anything. The recommended order for assembling the
parts is as follows:
a) The chipper cone
b) The top hopper panels and handle
c) The discharge deflector
d) Removal of chipper/shredder from wooden pallet
Options That Will Make the Job Easier:
▲ Ratchet with 7/16" & 1/2" socket attachments
▲
Top of a box (to hold loose nuts & bolts)
▲
Block of wood (approximately 2" x 4" x 6")
▲
Nail polish remover (to remove any excess tape adhesive)
▲
A friend (to help with assembly)
A
Assembling Your Chipper/Shredder
Uncrating Your Chipper/Shredder
NOTE: Save the two separate side panels of the box which you
can cut and tape to make four leaf pushers. See panels for
instructions.
2. Remove the paper cover from the elliptical hole. Install the
chipper cone over this hole using the three 3/8" x 3/4" hex
head bolts and three split ring lockwashers. (See Illus #1.)
Leave the bolts loose at this point. Align the inside of the
hopper at the bottom for a flush fit. To do this, hold the
chipper cone from underneath with one hand and look down
inside the chute to see that the bottom part of the chute (on
the inside) is aligned as flush as possible with the bottom of
the chipper intake hole. Slide the chute up or down as
needed to improve the fit. Then tighten the screws with your
free hand (so that the chute stays in position) and finally
tighten all three bolts securely with a 1/2" wrench.
Now that you have removed the box and are familiarizing
yourself with the manual:
1. Remove the loose parts, count them and set them aside.
Remove the tape carefully from the unit to protect the paint.
2. Remove the tie down that holds the chipper/shredder to the
pallet.

FINAL ASSEMBLY
hopper end and finally through the handle. Inserting the
Phillips screwdriver in one set of the holes will help align
the holes for easy insertion of the screw. Loosely install the
nuts on the bottom of the handle.
Attach the hopper front and right-hand plastic guard the
same way as described for the hopper back. Install the final
eight short screws and nuts. After all 18 screws are loosely
installed, use a 7/16" wrench or ratchet and #2 Phillips
screwdriver to tighten them securely. Tighten the lower
screws first and the upper ones last by turning each nut and
holding the screw. If you accidentally drop a screw inside
the machine, simply remove the discharge screen, reach in
and take it out.
4. Install the discharge deflector using the two 1/4" push-nuts
and the 1/4" rod. (See Illus. #1.) Tap one push-nut onto the
rod and insert the rod through the deflector and main frame
lugs. Tap the second push-nut securely onto the other end of
the rod. This can be tricky. One technique is to push the
second pushnut by hand onto the end of the rod so that it
stays in place. Then, with one hand hold a block of wood
tightly against the end of the rod with the secure push-nut.
With your other hand, hit the loose push-nut with the
hammer.
Illustration #1
CAUTION: AS A FINAL STEP, REMOVE THE
DISCHARGE SCREEN AND USE AN ALLEN WRENCH
TO MAKE SURE THAT ALL FOUR ALLEN BOLTS
WHICH HOLD THE CHIPPER KNIVES ON ARE
ABSOLUTELY TIGHT. BEFORE REPLACING THE
SCREEN, ALSO CHECK FOR ANY HARDWARE OR
TOOLS WHICH MAY HAVE FALLEN INTO THIS AREA.
REPLACE THE DISCHARGE SCREEN, SCREEN RODS,
ROD HOLDER AND ROD HOLDER NUT.
Illustration #2
C
NOTE: Do not forget the lockwashers! The chipper knife may
be damaged if the bolts are installed without them.
Servicing the Engine
Engine oil and gasoline must be added before starting. See
your engine operating manual or your authorized engine service
center for all repairs, parts and warranty service on your engine.
3. Assemble the top hopper as follows: First, install each of the
two identical hopper ends with the short screws, but don’t
tighten them. Next, peel the protective cover off the top of
the hopper guards. The easiest way is to first pull the cover
partially away from the guard along the uncut edge and then
pull the covering all the way off the fingers.
D
12 V.D.C. Electric Start Option
1. Your 12 Volt Battery is shipped without electrolyte and
must be serviced and charged by a professional at an
automotive service facility.
Attach the hopper back (the one panel with two decals) and
one hopper guard over the engine. (See Illus. #2.) The
hopper guard is placed between the hopper back and the
flange on the main frame. Insert a #2 Phillips screwdriver in
one set of holes to align all three holes so you can insert four
of the 14 short screws, head side to the inside of the hopper.
Loosely install the nuts on the outside of the flange of the
main frame.
CAUTION: BATTERIES MUST BE HANDLED
VERY CAREFULLY. THEY CONSTITUTE A POTENTIAL
HEALTH RISK AFTER THEY ARE SERVICED,
BATTERIES CONTAIN SULFURIC ACID WHICH CAN
CAUSE SEVERE BURNS. THEY ALSO PRODUCE
POTENTIALLY EXPLOSIVE GASES WHICH CAN CAUSE
PERSONAL INJURY. BECAUSE THEY ARE PART OF AN
ELECTRICAL SYSTEM, IMPROPER HANDLING CAN
CAUSE BURNS OR ELECTRICAL SHOCK PLEASE
FOLLOW INSTRUCTIONS CAREFULLY.
Attach the handle using the four longer screws. The screws
go through the hopper back first, then the flange on the

elbow, slip the tubing over this elbow and route the tubing
between the cover and bracket next to the hold-down bolt
Trim off the excess tubing on the opposite side of the
bracket. (See Illus. #3.)
4. Install the key switch between the handle and back hopper
plate using the upper right hand bolt. (See Illus. #4.)

OWNER/OPERATOR
SAFETY INSTRUCTIONS
▲
▲
Before Starting Your
Chipper/Shredder
▲
Read and understand the Owner/Operator Manual
▲
Always operate your unit alertly.
▲
▲
Always stop the engine, allow the grinder to come to a full
stop, disengage the grinder and disconnect the spark plug
wire before performing any clean-out or maintenance, even
for the simplest clean-out requirement.
Always use extra care in handling gasoline and other fuels.
These fuels are flammable, and their vapors are explosive.
- Use only an approved gasoline container;
- Never remove gas cap or add fuel with the engine running.
Engine must be cool before refueling. Operators should not
smoke;
- Never refuel the machine indoors;
- Never store the machine or fuel container inside where
there is an open flame, such as a water heater.
Always wear safety glasses or goggles when operating this
equipment.
Always wear gloves.
▲
Avoid wearing loose-fitting clothing.
▲
Operate your unit on firm, level ground (dirt or grass).
▲
Make sure all parts and fasteners are tight before each use.
▲
Make certain the grinder chamber is empty before starting
▲
▲
Hearing protection may be helpful.

▲
▲
Some “Do’s"
▲
▲
▲
If you have any questions about operating or maintaining your
unit after reading the owner/operator manual, call the dealer
you bought your unit from for the answers to those questions.
B
▲
▲
Injuries may occur if operators attempt to clean out the
discharge chute with their hands, feet, sticks or similar probes,
or put their hands into the inlets with the engine ON or with the
rotor turning. This procedure constitutes negligent operation
of the machine and MUST be avoided. Even after the engine
is turned OFF, the rotor assembly gradually coasts to a stop.
You MUST wait until the rotor assembly is stopped before
attempting any clean-out or maintenance.

Inspect material to be processed to make sure it is free of
rocks, glass, metal and other foreign objects.
Keep the engine clean of debris and other accumulations.
Keep all guards and deflectors in place and replace them
when they are cracked or broken.
Stay clear of the discharge area when operating this
equipment.
Keep your face and body back from the feed openings
when operating this equipment.
Keep your footing and balance when operating this
equipment.
Know your controls and how to use them.
▲
It is the owner’s/operator’s responsibility to insure that no
person is injured due to operation of a chipper/shredder. You
and all others who will operate this equipment MUST read
and follow all operating instructions in the owner/operator
manual and use your good judgment.

Operate only with the grinding screen securely in place.
Some “Don’ts"
Never allow children to operate this equipment or be in the
area when it is operated.
Do not operate your unit near bystanders.
Never operate your unit in an enclosed area. Carbon
monoxide in the engine exhaust is colorless, odorless,
tasteless and lethal.
Never put hands, feet or loose clothing in hopper inlets, in
the discharge area or near any moving parts.
Never attempt even a minor clean-out of the inlets or
discharge with the engine running.
Never operate your unit on a paved or gravel surface.
Do not operate your unit if unusual vibration or noise
occurs. (See the Troubleshooting section of this manual.)
Do not allow materials to build up in the discharge chute.
This may result in kickback of material through the feed
opening.
Do not overreach and possibly slip or lose your balance
when feeding material.
Do not operate in a slick, wet or congested area.
Do not tamper with the throttle or governor stops which
protect the engine and rotating parts from overspeed.
Authorized service should be obtained if a problem with the
governor exists.
Do not transport your unit while the engine is running.
Do not refuel your engine until it has cooled down. Use an
appropriate gasoline funnel.
D
Safety Decals
3
Your unit has been designed and certified to meet the latest
OPEI/ANSI safety standards. Part of this certification requires
that safety decals also meet these standards and are replaced in
time due to abrasion, etc. It is your responsibility to replace the
decals when they become hard to read. The part numbers for
ordering decals are in the Illustrated Parts section of this
manual.

HOW YOUR
CHIPPER/SHREDDER WORKS
Controls
(See Illus. #5 and your engine manual.)
A. Engine Choke: Use for starting as described in your engine
manual.
B. Engine Throttle:
a. Low or Idle. This position may be used only before or
after the chipper/shredder assembly is engaged by the
clutch bar.
b. Fast. This position must be used while you are chipping,
shredding and grinding.
C. The OFF or STOP Control: This position of the throttle is
used to stop the engine and rotor. (On electric start models
the key switch also has an OFF position.)
D. Clutch: The clutch allows engine power to be transmitted to
the chipper/shredder rotor.
-DISENGAGE THE CLUTCH ONLY FOR STARTING.
-DO NOT DISENGAGE THE CLUTCH WHILE THE
UNIT IS RUNNING OR UNNECESSARY WEAR TO
THE DRIVE BELT MAY OCCUR.
-The notch in the bar holds the clutch in the disengaged
position which allows the engine to warm up.

Maintenance
1. To perform any clean-out, service or maintenance:
a. Move the engine throttle to: “OFF" or “STOP."
b. Allow the engine and grinder assembly to come to a
complete stop.
c. Disengage the grinder.
d. Disconnect the spark plug wire from the spark plug and
place the end of the wire in the holder on the engine.
2. Allow the engine to cool several minutes before adding
gasoline or oil. Always use a proper funnel to avoid spillage.

B
Chipper
(See Illus. #6 )
Limbs inserted through the chipper cone pass through an
elliptical-shaped opening formed by the steel chipper block.
The chipper knives mounted on the heavy flywheel pass by the
chipper block and chip off the end of the limb. The chips pass
through the slot in the flywheel to which the knives are
attached and exit through the grinder chamber and screen.
Illustration #6
C
Shredder/Grinder
(See Illus. #7)
Materials fed through the two hopper guards in the
shredder/grinder hopper are directed into the path of triangular
swinging hammers. These hammers impact the material and
shred or grind it against the baffles and/or screen until it is small
enough to exit through the holes in the screen. The discharged
material may be either bagged directly or allowed to fall onto
the ground.
When the rotor assembly is spinning, centrifugal force causes
the hammers to swing outward and shred or grind the
material they hit. Because each hammer swings freely, if it
hits material too heavy to shred or grind, it will swing back
out of the way without significantly lowering the engine RPM
or jamming the machine. Then the next hammers, each in turn,
strike the material until it is reduced small enough to go through
the screen.
The triangular hammers are attached to the shredding cylinder
shafts at their apex. The tips at the wide base of the triangle and
the leading edge actually do the shredding. This provides more
mass at the shredding tip of the hammer for greater force. Also,
the center-of-mass of the hammer is further out from the center
of the shredding cylinder, which generates even greater force
and shredding power as the rotor assembly turns.
Illustration #7
The friability (breakability) of the material fed into the grinder
hopper determines whether it is shredded or ground. For
example, green limbs will be shredded, whereas hard, brittle
wood will be ground.

OPERATING INSTRUCTIONS
Site Selection and Operator Area
CAUTION: BE SURE TO OPERATE YOUR
CHIPPER/SHREDDER OUTDOORS IN A WELLVENTILATED AREA, AWAY FROM CHILDREN
AND PETS.
Select a level area of dirt or grass either close to the material
you are going to process or where you wish to discharge the
material after processing. Allow yourself room to work around
your unit without stumbling and with enough clearance to
handle the material. Avoid wet, slippery or congested areas
which might cause a dangerous fall. Avoid driveways or areas
with gravel which might deflect discharged material toward
others.

for Operators & Bystanders
Direct Bagging Options
Illustration #8
If you desire to direct-bag the discharged material, purchase
heavy duty, 30-gallon plastic garbage bags (or double-up light
duty bags).
1. First Method (See Illus. #9.) Place one of the rubber bands
(provided) as far back on the discharge chute as possible.
Lay a bag out flat on the ground with the seams to the sides.
Pull the open top of the bag over the discharge chute. Pull
the rubber band over the edges of the bag on the sides,
bottom and part of the top of the chute. Leave an opening at
the top of the bag to let the air out.
As the discharged material starts filling the bag, it may
eventually begin to back up into the discharge chute. At that
time, lift the bag off the ground near the chute and roll the
material back toward the bottom of the bag. (See Illus. #9.)
Illustration #9
2. Second Method (See Illus. #10.) Lay a bag out flat on the
ground with the seams to the sides. Pull half the length of
the bag over the discharge chute and lay a brick or log just
inside the bag on the ground under your unit. As you operate
your unit, keep the discharge chute free of material by lifting
and rolling the material back toward the bottom of the bag.
Also reposition the bag further out as it fills.
CAUTION: IF MATERIAL MUST BE CLEARED
FROM THE BOTTOM OF THE DISCHARGE CHUTE,
STOP THE ENGINE AND ALLOW THE ROTOR TO
COMPLETELY STOP. DISENGAGE THE GRINDER
CLUTCH AND USE A STICK OR SIMILAR OBJECT TO
CLEAR THE MATERIAL OUT — DO NOT USE YOUR
HANDS! OTHERWISE, PERSONAL INJURY MAY
RESULT.

2. Shredding/Grinding: Practically any organic material can
be put into the grinder. However, many variables will
determine the degree of satisfactory performance. Some
experimenting may be necessary. Here are some guidelines:
1. Chipping: Any limbs up to 3" in diameter may be fed into
the chipper. Some limbs will require the use of shears to
trim the largest branches off, while others will readily fold
themselves into the cone-shaped hopper.

1. Material under 3/4" in diameter and under 18" long may be
fed into the shredder-grinder hopper.
2. Limbs over 3/4" in diameter may be either pushed in with
another limb or pulled out, cut into short chunks and fed into
the grinder hopper or set aside for firewood. Do not let go of
large limbs and allow them to bounce around in the hopper
cone. They may damage the hopper cone or be ejected back
out toward the operator and cause injury.
Starting Your Chipper/Shredder
1. Before-start check list:
a. Turn engine OFF and temporarily disconnect spark plug
wire.
b. Familiarize yourself with your manual..
c. Select site, material and screen.
d. Check your unit for security of parts and fasteners.
e. Check the chipper and grinder chambers for foreign
objects.
f. Check the engine oil and fuel, and service if necessary.
g. Disengage the engine from the chipper/shredder rotor for
starting by pushing the clutch bar in until the notch on the
clutch bar is engaged. (See Section 3)
h. Reconnect the spark plug wire.
2. Ready to start: (See Section 3)
a. Set the choke per engine manual.
b. Set the throttle about one-half towards “FAST."
c. Start the engine using the recoil starter (or key-start on the
electric start model). Also see engine manual.
d. Move the choke to “OFF" as the engine warms up.
e. Engage the engine to the chipper/grinder rotor by lifting
up on the clutch bar slightly, releasing the notch, and
allowing the spring tension to gradually push the clutch
bar outward.
NOTE 1: When operating the 612 model, engage the
clutch slowly to prevent the engine from stalling.
NOTE 2: New v-belts are stiff and result in minimum
disengagement of the rotor assembly. (With a new vbelt, the rotor may turn slowly even when disengaged.)
After initially engaging the rotor, allow your unit to
“break-in" your new v-belt. The proper
disengagement should occur after 10 to 15 minutes of
operation.
f. Move the throttle to FAST for operating.
g. Your unit is now ready to chip, shred and/or grind.

Illustration #11
Using the Chipper
Align the limbs to be chipped in front of your unit with the
trunks closest to the chipper hopper cone. (See Illus. #11.)
Select a limb, trim as necessary for easy feeding, and insert into
the hopper. Depending on the horsepower of the unit you are
operating and the size of the limb, feed the limb at a rate that
does not stall the engine. Some RPM drop is normal; however,
the best performance will be obtained by alternately inserting
and retracting the limb at a rate which keeps the engine
operating in the higher RPM range. When the limb is reduced
to the length of the chipper hopper cone, you have two choices
according to the diameter of the material.

Operating Helps:
▲
▲
▲
▲
▲
▲
▲
▲
E
Rotate large limbs while alternately inserting and
retracting.
Several smaller limbs may be inserted together.
If fresh-cut limbs with wet, green leaves plug up the screen,
alternately chip or grind a very dry limb to unplug the screen
or use a screen with larger openings.
Stack limbs with butts together, near the operator side.
Chipping limbs while they are fresh is easier, prevents dust,
and produces moister, more uniform chips.
Limbs too large for chipping make good firewood.
Resharpen the chipper knives often. Dull knives put
unnecessary strain on your unit.
The throttle may be moved to “Idle" position while you do
other chores such as gather limbs, leaves etc. HOWEVER
THE CLUTCH MUST BE LEFT ENGAGED.
Illustration #12
Using the Shredder/Grinder
First, refer to the Material Selection Guide (Section 4.) It is
impossible to list all the materials that can be processed.
However, some examples are given as a guide to processing
similar materials.
1. Dry, loose leaves, grass or garden refuse
Dump them into the hopper. Use a cardboard pusher to push
the leaves through the guards and into the grinder chamber.
(See Illus. #12.) Use a steady, even feed rate that allows the
engine to operate in the higher RPM range.
2. Limbs, sticks, branches
Generally, limit the size to 3/4" diameter x 18" long.
(Longer lengths may whiplash as they are being pulled in
and this may cause injuries.) Feed limbs trunk first straight
down through the guards into the grinding chamber. The
grinder will pull them in. Do not hold onto the material.
Push it in with an open hand. (See Illus. #13.)
3. Cornstalks, palm fronds, large tomato (and other) vines
Cut these materials into 18" lengths and feed them as in part
2 above.
4. Items not recommended:
brick, glass and metal. These are dangerous and may cause
injury. Soil and rocks will cause excessive wear on hammers
and knives.

the top two bolts. Set those two bolts aside and hold the
weight of the engine while pulling it outward and down. The
v-belt will slip off the engine pulley. Now move the clutch
bar to the engaged position and unhook the spring from the
clutch bar. It is recommended that the spring also be
replaced whenever the belt is replaced. Be sure to take note
of which hole in the bar the spring is hooked into.
Whenever the pulley is removed from the engine shaft, it is
to be re-installed so that there is a distance of 1-11/16"
between the surface of the engine mounting plate and the
centerline of the pulley. (See Illus. #14.)
Whenever the pulley is removed from the grinder shaft, it is
to be re-installed so that there is a distance of 1-11/16"
between the outer surface of the vertical “N" brackets and
the center-line of the pulley. (See Illus. #15.)
2. V-Belt and Idler Pulley
Check the condition of the v-belt once a year or after each
25 hours of use, whichever comes first. To inspect, remove
the belt guard (two 5/16 bolts, 1/2" wrench) below the
To remove the clutch bar assembly and v-belt, remove the
guide pin on the clutch bar assembly that holds the v-belt
12
into the idler pulley. Remove the v-belt. Then slide the
clutch bar completely to the engaged side, pull the opposite
end outward, and slide the bar to the left for removal.
a. Bearing on the back (pulley) side
Remove the engine, belt guard and clutch bar assembly
with the v-belt. Remove the chipper/shredder pulley and
1/4-square key by loosening the two set screws in the
pulley hub.
Before re-installing the engine, check the security of the
pulley set screws and the four bolts securing the engine
mount to the engine.
The bearing lock collar may now be removed by
loosening the set screw (5/32 Allen wrench) in the collar.
Then put a 1/8" drift punch in the hole provided in the
collar and tap the punch sharply with a small hammer in a
direction opposite to shaft rotation to rotate and loosen the
collar. (To remove: rotate counter clockwise on pulley
end and clockwise at the opposite end.) Use #180 emery
paper to clean the shaft and remove set screw marks for
easy bearing removal. Use a 1/2" wrench to remove the
three bolts holding the bearing and flangettes. Slide the
assembly off the shaft and clean and oil the shaft.
This is also the time to inspect the idler pulley bearing, the
pulley flanges and the security of the retaining nut.
Excessive bearing wear will allow the idler pulley to feel
loose and dry. When replacement is required, use a new
self-locking nut.
Slide the clutch bar and idler pulley assembly back into
place. Install the new v-belt between the idler pulley and the
guide pin, then tighten the guide pin nuts. Hook the new
spring into the same hole previously used. Slide the clutch
bar to the disengaged position and pull the v-belt upward
until all the slack is at the top.
Install the bearing guard, the flangettes and the new
bearing without the lock collar. Install and tighten the
three bolts with lockwashers in place. Slide the new lock
collar over the shaft, press it over and against the inner
ring of the bearing and turn the collar in the direction of
shaft rotation until hand tight. With the drift pin in the
collar hole, tap the drift pin sharply with a small hammer
in the direction of shaft rotation to lock. (To install: rotate
clockwise on pulley end and counter clockwise at the
opposite end.) Tighten the set screw. (It should have antivibration compound on it. If not, use Locktite or
equivalent.)
To re-install the engine assembly, hold it up next to the
mounting location and pull the v-belt out and over the
engine pulley. While exerting slight pressure inward, lift the
engine up until the engine mount flange clears at the top and
can be pushed into place. Install the four bolts with
lockwashers starting with the two at the top. Then tighten all
four while pushing in on the engine.
NOTE: New v-belts are stiff and result in minimum
disengagement of the rotor assembly. (With a new v-belt,
the rotor may turn slowly even when disengaged.) After
initially engaging the rotor, allow your unit to “breakin" your new v-belt. The proper disengagement should
occur after 10 to 15 minutes of operation.
Re-install the pulley and 1/4" square key using antivibration compound on the set screws. Re-install the
engine as described in Section 5.
b. To replace the bearing on the front (chipper) side, follow
the same procedure as above, starting with the removal of
the bearing lock collar.
3. Bearings
Your unit has two permanently lubricated and sealed ball
bearings which are protected by our patented Bearing
Guards. If replacement has been found to be necessary,
proceed as indicated in steps a. and b. described below.
4. Grinder Hammers and Shafts Your unit’s patented
triangular swinging hammers have six fresh cutting edges to
use as wear occurs. To use a new edge, proceed as follows:
a. Remove the grinder screen.
b. Remove the front and back closure plates.
c. Rotate the grinder assembly so the shaft with the worn
hammers is in front. Block the assembly from rotating,
and with a 3/16" pin punch, remove the roll-pin in the
short spacer. Note the relationship of the hammers and the
spacers. They must be replaced in the same location to
avoid interference and to maintain balance. The 1/2" shaft
through the assembly of the hammers and the spacers may
be driven out the slot created by removal of the closure
plates.
NOTE: Some units are equipped with a serviceable bearing
on the chipper side and are identified by the zerk fitting on
the outer flangette. Grease bearing after every 8 hours of
use.
NOTE: Chipper Knife Clearance
Whenever a bearing is replaced, the .105 inch clearance
between the knife and the chipper block must be checked.
Use a piece of 12-gauge steel for a gauge. To adjust the
clearance, both lock collars must be loosened. Using a
plastic mallet, tap the rotor shaft until the knife touches the
gauge when held against the chipper block. Hold the rotor in
that position while tightening the lock collars. Recheck the
clearance and adjust if necessary.

New =1/4"
Minimum after several sharpenings =1/16"
Sharpen both knives equally
d. Clean the shaft and inspect it for wear. Replace the
shaft if you can detect grooves in it. (Both the shaft and
the hammers are heat-treated steel. Do not attempt any
repairs on these parts.) Inspect the hammers for
elongated mounting holes, and if excessive wear is
found, rotate the hammer so a new hole and cutting
edge are selected. Also inspect the hammers for wear
as shown in Illus. #16. This is the minimum edgedistance from the pivot hole you intend to use after
wear has occurred.
e. Re-assemble the hammers and spacers as noted before
disassembly. Use new roll pins (3/16" x 3/4") during
assembly. Rotate the grinder assembly as required to
replace any other hammers and/or shafts. Pay particular
attention to removal and assembly to keep the hammers
properly spaced and the grinder assembly in balance.

Hopper Guards
These guards are made of very special durable material and will
take many hours of service. However, the guards have several
fingers which may break off in time. (Insert small limbs butt
first to help prevent breakage.) The fingers MUST BE
UNBROKEN and in place for your safety and to meet
certification requirements. Serious personal injury may
result if the shields are not intact. It is the owner’s or the
operator’s responsibility to maintain and replace these
guards if they break. (See parts list for part numbers.)
5. Chipper Knives
The knives will need to be resharpened periodically for
easier cutting.
a. Remove the screen and front closure plate, then rotate
the chipper assembly until the knife is most accessible.
Block the assembly from rotating and with a 1/4" Allen
wrench, loosen the two socket head cap screws and
remove the knife. Rotate the chipper assembly to the
second knife and remove it also. Sharpen them the
same amount to maintain balance in your rotor
assembly. Slow-speed, water-cooled grinding is
preferred to maintain the precision temper of the
knives. With care,
a homeowners bench grinder with a fine grit stone or a
machine shop can be used to sharpen them to the 30degree angle. (See Illus. #17.)
b. Clean the knife seat and adjacent area before reinstalling the knife. Re-install the knife into the eat
using two socket head cap screws (fine-thread) and
new lockwashers. Torque to 22-27 ft. lbs. with a 1/4"
Allen wrench provided.
