SET-UP INSTRUCTIONS
Your chipper does need to be set up prior to installation. It arrives in a steel
crate that can be dismantled in minutes. See Assembly Instructions
The in-feed bin and discharge chute are shipped with the unit and are locat-
ed in the bottom of the steel crate.
Visually inspect the in-feed bin, and the fly wheel before attaching to
tractor, and applying power to ensure that nothing is in the chipper head. If
the chipper deflector or any of the guards have been removed for shipping,
be sure to replace them properly before use.
The PTO (Drive-Line) is also shipped with the unit and is located in the bot-
tom of the steel crate.
When mounting, keep the chipper as close to the tractor as possible.
Make sure that the PTO shaft will not bottom out in the shortest position.
While in use, keep the PTO shaft straight. No more than 15 degrees from
level is acceptable.
Do not operate the chipper without the chip deflector properly in place.
Read and understand all assembly instructions prior to assembly.

Before you get started, there are a few tools you will need:
Assembly Time 2.5 Hours
Remove the plastic wrapping from the crate and inspect the chipper for any
obvious shipping damage.
Remove and unwrap all the chipper components that are packaged in the
crate.
Remove the cardboard box from
the in-feed bin. This box contains
the user’s manual, hardware pack-
et, extra shear bolts, and any ad-
ditional item that you may have
purchased such as extra chipper
knives. [Fig. 1a]
Open the hardware packet and organize the enclosed fasteners into sepa-
rate piles. There is a picture of the hardware on pg. 4 of this manual that you
can use as a guide to ensure that you use the correct hardware in the up-
coming steps.
Remove the four bolts that secure the top of the crate frame. Remove the top
of the crate, and set it aside.
Located on the bottom of the crate
is a cross bar that secures the chip-
per to the frame. Loosen the two
bolts that hold this bar in place, and
drive the bar forward with a dead
blow hammer. [Fig. 1b].

Locate the lift point on the top of the chipper. This is the balance point, and
the only point the chipper should be lifted from.
Using a chain or strap that is rated
strong enough to lift the weight of
the chipper, lift the chipper out of the
crate. [Fig. 2]
If you do not have a front end loader,
attach the three point hitch of your
tractor to the chipper to lift the chip-
per out of the crate.
Measure the distance from the PTO
spline of your tractor to the ground
[Fig. 3]. Write down this measure-
ment here ________. You will need it
for the next step.
While the chipper is raised in the air,
attach the four adjustable base legs
so that when the chipper is on the
ground, the spline of the chipper is
slightly lower than the spline of your
tractor. [Fig. 4]. The shaft does not
need to be perfectly horizontal, but it
is recommended that the slope of the
PTO shaft is no more than 15 degrees.

Before tightening the bolts, ensure that
the lower panel is slightly higher than
the in-feed bin. This will prevent mate-
rial from hanging up where the two
pieces join together. [Fig. 10]
Attach the top panel of the in-feed bin
by installing the four M10x25mm bolts
in the two forward holes of the panel.
Affix the safety bar stop to the top left
of the in-feed bin. [Fig. 11].
Attach the support leg with two
M10x25 bolts. [Fig. 12]. Remember, the
support leg should be in the down po-
sition during storage only. When the
chipper is attached to the tractor, the
support leg should be in the up position
at all times.
Attach the upper feed roller assist lever
using four M10x25mm bolts. [Fig. 13].

Fasten the chain from the upper feed roller
assembly to the feed roller assist lever. The
hardware for this is found located on the
end of the chain. [Fig. 14].
Connect the safety bar to the top side of
the in-feed bin. First remove the bolt and
nut on right arm of the safety bar. Hold
the safety bar in place, so that you can
read the word STOP, and the arrows point
downward. Hook the bolt on the left arm
of the safety bar through the hole on the
top of the edge of the left in-feed panel.
[Fig. 15].
Align the hole on the right arm of the safe-
ty bar with the hole in the top edge of the
right side panel, and reinstall the bolt and
nut that you removed in the previous step.
[Fig. 16].
Thread a M10 locknut onto the bolt on
either side, but do not tighten these nuts.
This is a hinge point and the bar must
move freely. [Fig. 17].
Adjust the clutch cable length so that it is
tight but not so tight that it starts to dis-
engage the clutch. Attach the end of the
clutch cable to the safety bar. [Fig. 18].

Connect the chipper to the 3 point hitch
of your tractor. [Fig. 21].
Note: Please check to make sure all
nuts and bolts on machine are
tightened after you complete
assembly, and before machine is first
used. This step has not been done for
you prior to shipment, except for the
flywheel bolts and knife bolts.

ASSEMBLY INSTRUCTIONS
Now, the shaft must be sized according to this measurement. Refer to the
chart on the bottom of page 18 to determine if the shaft must be cut to
size. If so, see the “PTO shaft cutting instructions” on page 19 .
After properly sizing the shaft, locate
the three grease fittings on the shafts
U-joints, and pump several shots of high
quality grease into the fittings. [Fig. 24].
NOTE: Check to ensure that the
zerk (grease) fittings are screwed in
tight. Occasionally, dried paint may
cover the end of the zerk fitting
on the PTO shaft. Remove this by
scraping the paint off with a knife
prior to attempting to pump grease
into these fittings.

DRIVE LINE SAFETY TIPS
10
Agriculture and forestry are recognized as one of the most hazardous of oc-
cupations. Today’s farmer spends long hours in close proximity to increasing-
ly complex and powerful machinery.
To avoid accidents, everyone from the component supplier and the company
who manufacturers and assembles the machinery, to the dealers and ulti-
mately the actual user, must keep safety in mind. The checklist below relates
to the drive line of agricultural implements, general safety literature, and the
standards published by the American Society of Agricultural Engineers.
DRIVE LINE SAFETY CHECKLIST
Drive-Line Specifications – The first step towards safe applications is to specify
and test the drive-line so that it operates properly under expected field condi-
tions.
1. Specify and test the proper size joints and telescoping members based
upon the power required by the implement, speed of rotation, joints
angles, shock loads, and expected life.
2. Test the hitch geometry to prevent the drive line from:
• Extending beyond the recommended maximum length.
• Bottoming out.
• Reaching a position that allows universal joints to lock.
• Exceeding the maximum allowable angle for constant velocity of
the universal joints.
Information concerning these parameters may be found in all drive-line manu-
facturer’s catalogs.
3. Specify and test telescoping members to allow the lowest possible thrust
loads, considering the expected working conditions.
4. Specify and test torque limiters to control excessive shock loads.
5. Where necessary, specify and test overrunning clutches to prevent inertial
loads from overpowering the tractor.

DRIVELINE SAFETY CHECKLIST
11
Hazard Reduction - The second step in specifying a safe drive-line application is
to strive to eliminate as many hazards as possible
1. On drive-line with torque limiting or overrunning devices, specify that
the device be positioned to the end of the drive-line by the implement.
2. For implement connections which require bolts or set screws, select
and/or supply hardware which minimizes protrusions. Information
concerning these parameters may be found in all drive-line manufactur-
er’s catalogs.
3.For tractors PTO shaft connections, specify a safety type yoke (twist or
slide collar) to minimize protrusions.
4. Provide a proper clearance zone for the operation of the drive-line, to
avoid damaging the shielding components.
Some common areas of interference are:
• Three point linkage.
• Extended or eye loop hitch pins.
• Hydraulic hoses.
Guarding – For hazards which cannot be eliminated effectively, guarding must
be provided whenever feasible.
The PTO master shield, integral drive-line shield, and implement input connec-
tion shield should provide an interactive guarding system.
1. Provide instructions by labels or manuals. The implement should be used
only with the tractor’s PTO master shield in place.
2. Specify and test an integral drive-line shield with end cones which overlap,
but not interfere with the PTO master shield or implement input connection
shield.
3. Provide an implement input connection shield to interact with the integral
drive-line shield to provide guarding of the shaft coupling and any torque limit-
ing devices installed on the drive-line.
4. Check that all routine maintenance of the drive-line can be done without
removal of the shields.

DRIVELINE SAFETY CHECKLIST
12
Warnings and Instructions – Provide warnings and instructions for hazards as-
sociated with the machine. Provide instructions for proper maintenance and
repair.
1. Provide labels on the unit to advise the user of proper hitch dimensions
and maximum safe operating speed.
2. Check that proper danger labels are supplied with the drive-line con
cerning these parameters may be found in all drive-line manufacturer’s
catalogs.
3. Provide easy-to-understand instructions for proper drive-line operation,
maintenance, and repair in the operator’s manual.
4. Advise against the use of PTO adapters which may defeat the purpose
of the tractor’s master shield and adversely affect the performance of the
drive-line.
5. Advise the user of locations of genuine original equipment spare parts.
Further information about drive-line specifications and safety may be obtained
from your drive-line supplier and the following ASME standards and engineer-
ing practices:
S203 – Rear power take-off for agricultural tractors
S205 – Power take-off definitions and terminology for agricultural tractor
S207 – Operating requirements for tractors and power take-off driven equip-
ment implements
S318 – Safety for agricultural equipment
S331 – Implement power take-off drive-line specifications
S333 – Agricultural tractor auxiliary power take-off drives
S350 – Safety alert symbol for agricultural equipment
S441 – Safety signs
S493 – Guarding for agricultural equipment
EP363 – Technical publications for agricultural equipment
Other standards may apply for particular types of implements. All drive-line
manufacturers strive to produce a safe product. Drive-lines, like most other
components must be used properly, including the use of proper tractor master
shields and implement input connection shields. Please contact us if you have
any questions about your drive-line applications.

SAFETY INSTRUCTIONS
13
Do not attempt to operate the chipper until you have read and understand
the owner’s manual. If you need a new one, you can visit
www.wooodmaxx.com
Keep the decals in place and in good repair. We will furnish new decals
upon request.
It is NOT recommended to operate the chipper in temperatures below
freezing. Hardened steel (as used on knives) can become brittle in tempera-
tures below freezing and may result in breakage.
Always keep the guards and chip deflector installed properly while operat-
ing the chipper.
Never leave the chipper running unattended.
Do not attempt alterations, repairs, or adjustments while the flywheel is
turning. Always disconnect the PTO, stop the tractor’s motor, and put the
keys in your pocket prior to attempting any alterations, repairs or adjust-
ments.
Keep hands, feet, and other extremities out of and away from the hopper
(in-feed bin).
Point the discharge chute away from doorways, sidewalks, or any other
area where your view is obstructed. The chute should be pointed down-
wind when possible. This will keep the chips from blowing back in the op-
erator’s direction.
Keep everyone, especially children, away from the area of operation.
No loose clothing should be worn around the chipper. Personal injury can
occur if someone or something turns the flywheel over when the knives are
WEAR PROTECTIVE GEAR!
EYES – wrap around safety glasses
EARS – ear plugs
HANDS – leather gloves
FEET – steel toed boots
LEGS – heavy pants
ARMS – long sleeved shirt

MACHINE CHECKLIST
CAUTION: Visually inspect the in-feed bin and the flywheel before applying
power to ensure that the chipper head is clear, all the bolts are clear, and the
knives clear the case and the cutter bar.
Make sure that:
1- Bystanders are at a safe distance from chipper during operation
2- Children should NEVER operate, or be near the chipper during operation.
3-The PTO shaft does not come apart or bottom out during the normal lifting
range.
Check the chip pile to see if the knives need to be serviced. Long slivers in the
chip pile are one of the best indicators of dull knives.
14
MACHINE OPERATION
The chipper is a flywheel-and-knife type of chipper, not a shredder. The knives
actually chip the limbs they are fed into the head. The knives must be sharp to
operate properly. Dirt, rocks, nails, or other foreign material will shorten knife
life.
Before operating the chipper, review the machine checklist. After visually in-
specting the fly wheel and in-feed bin to ensure there are no obstructions
in the chipper head, start the tractor. Make sure the chipper is firmly on the
ground and that the PTO shaft is no more than 15 degrees from level. The chip-
per must be resting on solid ground prior to operation. DO NOT operate while
raised by 3 pt. hitch.
Start the chipper slowly (idle) with the PTO engaged. Gradually increase en-
gine RPM until the tractor PTO speed is 540 RPM (not 540 engine RPM) The
chipper is designed to run at 540 RPM. Lower RPM can damage the chipper if
material jams and stops the flywheel. The material will feed into the head more
easily if you start the pieces with the large end first.
The feed rollers will fold branches as they are pulled into the hopper. Occasion-
ally, a limb fork may have to be cut to feed properly. If the material stops feed-
ing, sometimes a little push on the long end of the limb will help.

MACHINE OPERATION
Remember to chip only clean material, or knife life will be shortened.
Do not move the chipper while the flywheel is turning.
Block the tractor wheels and set the parking brake while running the chipper.
Watch the discharge chute while operating the unit, and if the chips stop flow-
ing, stop feeding material into the unit by pushing forward on the hydraulic
control valve handle located on the side of the in-feed bin.
Most of the time this will be enough to clear the chips out of the unit. If the
unit slows down noticeably, first shut off the PTO power, then the tractor. Un-
plug the head by turning it backwards by hand with the discharge chute and
the top section of the flywheel housing wrap off.
Remove the chips from the top of the head. If this fails, remove the clean-out
door, located in the lower part of the front side-plate of the chipper below the
main shaft, and then work the chips out of the case.
Replace the clean-out door after all the chips are removed, be sure to use both
the lock washers and flat washers.
Do not operate the chipper without the chip deflector in place.
Before stopping the chipper, be sure that all of the material is out of the chip-
per head and out of the in feed roller.
All of the material in the chute must be gone or the unit could jam on a small
piece of material. This can usually be cleared by turning the unit backwards by
hand.
Dull knives cause many problems such as: seeming lack of power, plugging of
the discharge chute, rough cutting with more vibration than usual, feed roll
shaft broken, main bearing house broken, main bearing working loose and the
flywheel or knives hitting the case or bed knife, feed roller kicking out of gear,
and not feeding.
When sharpening the knives, be careful to keep angle A at a 37°-39° angle.
Knives cannot be rounded, or the knives will not pull the material into the
head. (See Flywheel Knife Sharpening Instructions on pg. 22)
The best way to tell if the knives need sharpening is to watch the chips coming
out of the chip discharge. If they are long and straight, the knives are in need
of service. Sometimes the knives feel sharp to the fingers, but may be worn or
rounded. They will need to be sharpened.
15

LUBRICATION
Bearings - grease all bearings every 10 hours of operation.
PTO Shaft – grease the two grease zerks on the universal joints 10 hours of
operation with high quality grease.
In-feed Roller Drive Axle – lubricate with way oil (chain saw bar oil) every 10
hours of operation. Occasionally remove and thoroughly clean this assembly
pg. 26
Feed Roll Clutch – while feed roll shaft is off, lubricate the feed roll clutch in-
side and out with a high quality grease pg. 26
Gear Box – add oil (90w) as necessary and change after 40 hours of use.
Shear bolt replacement-- Grade 2, size 5/16”x 2”
16
PREVENTATIVE MAINTENANCE
Visually check all bolts, set-screws and fasteners after running 10 hours, and
once per day thereafter.
Check for loose belts and broken pulleys, loose springs, dry slides, and proper
lubrication of both feed roller drive-axle and feed roller clutch.
The main drive belts on the chipper need to be tight.
The belt of the main drive on the PTO chipper should be checked every 10
hours of operation.
All decals and safety instructions should be kept clean and legible. It is the
operator’s responsibility to replace the decals as needed. They will be mailed to
you at no charge.

DRIVE LINE FITTING ADJUSTMENTS
18
This data is for drive-line fitting adjustment.
Prior to startup, the PTO that is supplied with your chipper must be properly
sized to insure proper operation. If this is not done, damage to the chipper,
PTO, and tractor PTO drive-line will occur. These calculations are based on the
following assumptions:
The drive-line has an active length range of 20-3/4” to 25-1/4”
The two shaft ends are horizontal with one another
The following steps should be taken to insure the proper fitting of the PTO
drive-line (provided with your chipper) with your tractor PTO drive.
Attach the chipper to your tractor’s three point connections.
Raise the chipper to a position where its drive-shaft is level with the tractor
PTO drive-shaft. The horizontal position is recommended for operation of the
chipper. A maximum of 15 degrees of offset from the horizontal position be-
tween the two shaft ends is allowable for proper operation of the unit by the
PTO drive-line manufacturer. However, drive-line calculations are based on a
level horizontal position.
With the two drive shafts level with one another, measure the distance be-
tween the ends of the two shafts. (The chipper and the tractor PTO shaft ends).
This distance between the two shaft ends is the measured shaft end distance,
or “MSED”. [Fig. 23, pg. 8] The PTO drive-line is capable of handling a MSED
between 20” to 25-1/2”, allowing for at least 1/3 of shaft overlap as recom-
mended by the drive-line manufacturer.
If the MSED is longer than 25-1/2”, a longer drive-line is needed and should be
ordered.
If the MSED is shorter than 20”, extend the draw arm of the chipper outward
until a minimum of 20” is achieved.
MSED
Between 23-1/4” x 25-1/4” No adjustment needed
22” Cut 1” from each shaft
21” Cut 2” from each shaft
20” Cut 3” from each shaft

19
DRIVE LINE FITTING ADJUSTMENTS
Most drive-lines can be adjusted to fit by cutting off equal amounts of the
ends of the shaft and the guard tube of the PTO drive-line. In no case can
more than 3” of shaft and guard tube be removed, or the contact area is
not sufficient for proper and safe operation of the drive-shaft. Cut off the
same amount from the shaft tube plastic cover and the guard tube safety
cover to insure proper assembly and fit of the drive-line. Consult the drive-
line manufacturer data enclosed with your drive-line for proper assembly,
disassembly, lubrication and operation prior to startup and during opera-
tion.
REMEMBER: Contact with the drive-line while in use can result in seri-
ous injury or death. Any portion of the drive-line while not shielded
must be guarded by an interactive guarding system. The manufacturer
of the equipment is responsible for providing guards. Any replacement
guard must be one which is specified by that manufacturer. In short,
do not remove any of the plastic safety
covers on the drive-line and insure that caution is used around this
drive-line. No one should be in the drive-line area when it is operating.

To cut the PTO shaft, unhook chain, and separate the two halves. Mark and
cut equal amounts off of the plastic shields. Then mark and cut the same
mount off of the steel shafts. De-burr , grease, and reassemble the shaft. Short-
en the chian so that there is no slack when the shaft is extended to its longest
point
