Although there are no operational restrictions on the
Wood Chipper when used for the first time, it is recom-
mended that the following mechanical items be checked:
• After operating for 1 hour:
1. Torque all fasteners and hardware.
2. Check condition of rotor bearings.
3. Check the condition and clearance of the twig-breaker,
rotor and stationary blades. Adjust or replace as required.
4. Check for entangled material. Remove all entangled
material before resuming work.
5. Lubricate all grease fittings.
• After operating for 10 hours:
1. Repeat steps 1 through 5 listed above.
2. Go to the normal servicing and maintenance schedule
as defined in the Maintenance Section.
Follow this procedure to prepare and setup the machine
at the work site:
1. Use the skid steer to position the Wood Chipper at the
work site.
IMPORTANT

• unpin and the feeder hopper latch
• carefully lower the hopper and secure it with the with
the nuts on the anchor bolts.
• Secure the feed hopper latch to the discharge chute
with the latch pin
A PTO drive line is supplied with the machine. To accom-
pany the variety of 3 point hitch geometry available today,
the drive line can be too long for most machines or too
short for others. It is very important that the drive line be
free to telescope but not to bottom out when going
through its working range. If the drive line bottoms out,
the bearings on both the machine and tractor PTO shaft
will be overloaded and fail in a short time.
Efficient and safe operation of the MechMaxx 3 Point
Wood Chipper requires that each operator reads and
understands the using procedures and all related safety
precautions outlined in this section . A pre- operation
checklist is provided for the operator. It is important for
both the personal safety and maintaining good mechani-
cal condition that this checklist is followed.
Before operating the Wood Chipper and each time there-
after, the following areas should be checked off:
1. Lubricate the machine per the schedule outline in the
Maintenance Section.
2. Check the rotor, blades, and twig-breaker. Remove any
twine, wire or other material that has become entangled.
3. Check the condition and clearance of the twig- breaker,
rotor, and stationary blades . Adjust or replace as
required.
4. Check that all bearings turn freely. Replace any that are
rough or seized.
5. Make sure that all guards and shields are in place,
secured and functioning as designed. Check the condition
of the curtain in the feed hopper. It must be in good condi-
tion to prevent chips

www. mechmaxx.com
OPERATION
1. To determine the proper length of the drive line, follow
this procedure:
a. Clear the area of bystanders, especially small children.
b. Attach the chipper to the tractor but do not attach the
drive line.
c. Raise the machine until the input shaft is level with the
tractor PTO shaft.
d. Measure the dimension between the locking grooves on
the tractor PTO shaft and the machine input shaft.
e. Measure the same dimensions on the compressed
drive line.
f. If the compressed drive line dimension exceeds the
machine dimension, the drive line will have to be cut.
a. Subtract the machine dimension (A) from the uncut
drive line dimension (B) or (B-A). This dimension deter-
mines how much too long the drive line is.
b. Add another inch (25 mm) to the dimension to be sure
it doesn't bottom out, to determine (C) the cut off dimen-
sion.
c. Use a hacksaw to cut dimension (C) from both ends.
Cut both the plastic tubes and the metal cores.
d. Use a file to remove the burrs from the edges that were
cut.
e. Assemble the 2 ends of the shaft.
f. Make sure the shaft can telescope freely. If it does not,
separate the 2 parts and inspect for burrs or cuttings on
the shaft ends. Be sure it telescopes freely before install-
ing.
2. When cutting the drive line, follow this procedure:
When attaching chipper to a tractor, follow this proce-
dure.
1. Clear the area of bystanders, especially small children.
2. Make sure there is enough room and clearance to
safely back up to the chipper.
3. Place the tractor arms in their full sway position.
4. Back up slowly and align the lower link arms to the

dure. Always park the machine in a dry, level area. If
vandalism is a problem, remove the PTO drive line and
store in a secure place.
Caution and care should be exercised when feeding mate-
rial into the feeder. Do not reach into the hopper past the
curtain barrier.
• Before beginning to feed the rotor is up to speed.
• Slowly slide the wooden material into the feed hopper
and move it into the rotor.
• Do not force the material into the rotor, as the material
engages the rotor, the rotor will draw the material in . Use
continuous lite pressure to guide in the material.
• Be aware of how much material you feed in, slow down
or stop if the rotor begins to slow down.
• Do not reach into the feed hopper further than the
curtain to be sure not to contact the blades on the rotor.
• Use a stick or branch to push any piece of material into
the rotor that does not move on its own. If the jam
persists then stop the engineand wait for the rotor to
stop and then clear the jam. Do not take a chance with
getting your hand caught in the rotor.
• Ensure your wood chip pile is contained and doesn't
affect the immediate work area.
Although the machine is designed to handle a wide variety
of material without any problem, occasionally it plugs .
When the machine plugs, follow this procedure to unplug:
• Clear the area of bystanders, especially small children.
• Turn off the hydraulics, stop the engine, remove the
ignition key and place it in your pocket and wait for all
moving parts to stop before unplugging.
• Pull the material out of the feed hopper. Be sure all the
material is out, and nothing is jammed or wedged
between the input opening and the rotor.
• Pull the material out of the discharge hood. Use a stick
to poke loose any material jammed
into the discharge hood. Do not allow anything to remain
in this area.
• Check that everyone is clear of machine before restart-
ing engine.

MAINTENANCE
By following a careful service and maintenance program
for your machine, you will enjoy many years of trouble-free
operation.
The rotor and ledger blades need to be sharp for the
Chipper to perform as expected . Periodic inspection is
recommended . Keep the blades sharp to reduce the
amount of power required during operation . Watch the
sharpness of the blades when processing material with a
lot of sand, soil or dirt mixed with it . Reverse or sharpen
the blades if the cutting edge becomes dull. Twig breaker
should be inspected for gouges or bent.
The rotor is equipped with 4 blades spaced evenly to keep
the rotor in balance . If one needs to be changed, the one
opposite should also be changed . It is recommended
that the rotor blades be removed from the rotor when
sharpening . Always sharpen the blades at a 45° angle to
provide the best cutting effect as it meets the stationary
blade. Be sure to tighten the blade mounting bolts to
their specified torque when reinstalling the blades to the
rotor.
1. Stop the engine, remove the ignition key, and place it
in your pocket and wait for all moving parts to stop.
2. Remove the bolt that secures the upper rotor housing,
and Carefully open the rotor housing.
3. Manually rotate chipper rotor plate so that the blade
is fully Exposed.
4. Remove the bolts that hold the rotor blade to the
rotor, remove the blade.
5. Rotate the blade and reinstall or replace with new or
resharpened blade.
6. Ensure the blade is properly oriented, with the leading
edge out. The blade is designed to fit into the rotor one
way only. See diagram for proper installation.
7. Tighten down bolts as specified in the torque chart.
8. Repeat steps for remaining blades.

Routine inspection of the knives for sharpness and wear
plate for a sharp edge will ensure that your wood chipper
is operating at full efficiency. Using dull knives or a round-
ed wear plate will decrease performance and cause
excessive vibration that will damage the machine and
make chipping difficult for the operator.

The MechMaxx-BX42S is equipped with a ledger (station-
ary) blade that acts as a shear for the moving rotor blades
. The ledger blade is designed with 4 usable corners .
When the corner facing the rotor blade rounds over,
remove the blade and reinstall with a different corner
facing the rotor blade . It is recommended that the clear-
ance between the rotor and stationary blades be set and
maintained at 1/32 to 1/16 " ( .76 - 1.52 mm) to obtain
the best performance.
1. Turn off the hydraulics, stop the engine, remove the
ignition key and place it in your pocket and wait for all
moving parts to stop.
2. Remove the 2 bolts that hold the ledger blade to the
ledger mount, remove the blade.
3. Rotate the blade and replace or replace with new or
re-sharpened blade.
4. Hand tighten the bolts and set the clearance between
the ledger and rotor blades at 1/32 - 1/16" .
5. Tighten down bolts as specified in the torque chart
The tables shown below give correct torque values for
various bolts and cap screws . Tighten all bolts to the
torques specified in chart unless otherwise noted . Check
tightness of bolts periodically, using bolt torque chart as
a guide . Replace hardware with the same strength bolt .
Torque figures indicated above are valid for non-greased
or non-oiled threads and heads unless otherwise speci-
fied . Therefore, do not grease or oil bolts or cap screws
unless otherwise specified in this manual . When using
locking elements, increase torque values by 5%. * Torque
value for bolts and cap screws are identified by their head
markings
