understand this manual and other safety
information provided with the base
machine and be sure that you
understand all controls and operating
instructions before attempting to operate this equipment.
Failure to follow the safety precautions can result in
personal injury, death or property damage.
Carefully read all safety messages in this manual and on
your equipment safety signs. Keep safety signs in good
condition. Replace missing or damaged safety signs.
Because LaBounty cannot foresee all hazardous
circumstances, the precautions listed in this manual and
on the equipment are not all-inclusive. If a procedure,
method, tool or part is not specically recommended by
LaBounty, determine whether it is safe for you and others,
and that the equipment will not be damaged or made
unsafe as a result of your decision to implement it.
The basic rules are summarized in this section of the
manual. They also appear throughout the manual along
with additional specic rules for safety and operation.
GENERAL
• If the attachment is not functioning properly, shut
down the machine, follow proper Lock-out / Tag-out
procedures and follow proper repair procedures.
• Remove and replace any damaged or worn parts
with parts recommended by LaBounty. Use of parts
that are not factory approved may cause damage or
unnecessary downtime and may void the warranty.
• NEVER operate equipment without the original safety
guards in place.
• DO NOT process material with the attachment over
the operator’s cab. Doing so will result in severe
personal injury or death from falling debris.
• DO NOT attempt to process brittle materials, such as
axles and railroad rail. DO NOT process any material in
a position that may propel it toward the operator, other
workers, buildings or equipment.
• Clear all persons and equipment from the area of
operation and machine movement. NEVER move
loads over people or equipment. When viewing the
operation of the attachment, maintain a safe distance
of at least 30 feet (10 meters).
• NEVER approach power lines with any part of the
machine. Keep clear at a minimum of 15 feet (5
meters).
• DO NOT close the attachment on a structure and
reverse the excavator in an attempt to pull down
material.
• Use of this tool on certain materials could generate
dust potentially containing a variety of hazardous
substances, such as, asbestos, silica or lead.
Inhalation of dust containing these, or other
hazardous substances could result in serious injury,
cancer or death. Protect yourself and those around
you. Research and understand the materials you are
processing. Follow safety procedures and comply
with all applicable national, state or provisional health

MRP Mobile Rotating Pulverizer Operation & Maintenance Manual | 5
and safety regulations relating to them. If appropriate,
arrange for the safe disposal of the materials by a
qualied person.
• Disassembly of any pin-connected attachment can
be hazardous. NEVER remove any pin unless the
attachment is on the ground and blocked up. Serious
injury or death could result. Metal chips or debris may
y when a connecting pin is struck. Use a brass drift
when striking pins and always wear protective clothing
and proper eye protection. Pins may y when struck
with force to drive them in or out. Always keep people
clear when removing or installing pins.
• Do not operate this, or any other equipment, under the
inuence of drugs or alcohol.
• DO NOT modify LaBounty equipment without factory
authorization. This equipment is designed to do a
specic job and alterations could result in injury.
• ALWAYS lower the boom to the ground before leaving
the cab. If it is necessary to work on an attachment
o the ground, securely support the machine and
attachment. DO NOT support the machine on cinder
blocks, hollow tiles or props that may crumble under
continuous load. DO NOT rely on a cylinder to hold the
attachment in the air. If a control is moved or hydraulic
pressure is otherwise released, the attachment may
drop. DO NOT work under a machine that is supported
only by a jack.
• DO NOT weld on any structural member unless
specically authorized by LaBounty. Unauthorized
welding will void the warranty, may cause structural
failure and could result in personal injury.
• Keep clear of potential pinch points, including the
moving upper jaw, cylinder connections, bucket
linkages and other moving parts.
• Before operating the attachment, read and observe
all safety instructions in the Operation & Maintenance
manual. If you are unfamiliar with any operation or
maintenance procedure, seek instruction before
proceeding.
• Inspect the attachment daily. Do not operate a poorly
maintained or damaged attachment.
• Never operate a machine if an unsafe condition exists.
Attach a “Do Not Operate” tag to the machine.
BASE MACHINE
• Ensure that the cab is equipped with the proper safety
guards for LaBounty applications. The cab MUST be
equipped with an approved Falling Object Protection
Structure (FOPS) and cab guarding. The FOPS must
meet the requirements of SAE standard J1356. A
transparent, shatter-resistant shield covering the
front of the cab, is also required. Contact your base
machine equipment dealer or manufacturer for
more information on the availability of FOPS and cab
guarding. Lack of proper FOPS and guards may result
in injury or death.
• Avoid tipping. The attachment will alter the lift
capacities of the base machine. DO NOT overload
the excavator or serious injury could result. Lift
capacities will vary if the base machine is not on level
ground. Lifting incorrectly can cause severe injury or
machine damage. Use the recommended excavator
counterweight. Use short slings and lift the load only
as high as necessary.
• DO NOT allow riders on the machine. Riders are
subject to serious injuries, such as being struck by
foreign objects or being thrown o the machine.
Riders also distract and obstruct the operator,
resulting in the machine being operated in an unsafe
manner. NEVER use the attachment as a work
platform or personnel carrier.
• Check ground conditions before operating. Avoid
unstable or slippery areas and position the base
machine on rm, level ground. If level ground is
not possible, position the base machine to use the
attachment to the front or back of the carrier. Avoid
working over the side of the base machine.
HYDRAULIC
• Hydraulic oil becomes hot during operation. DO NOT
come in contact with hot hydraulic oil as it could cause
severe burns. Wear adequate protective clothing and
safety equipment.
• DO NOT tamper with hydraulic lines or components
while they are pressurized. Escaping uid under
pressure can penetrate the skin, causing serious
injury. Keep hands and body away from pinholes and
nozzles which eject uids under high pressure. Use
a piece of cardboard to search for leaks. If ANY uid
is injected into the skin, seek immediate medical
assistance.
PPE
• ALWAYS wear close-tting clothing and safety
equipment appropriate to the job. Safety equipment
should be worn at all times when viewing, operating
or maintaining the attachment. Safety equipment
includes eye protection, hard hat, steel toe shoes,
gloves, hearing protection and respirator.

General Rules For Safe Operation
• KNOW the capacity of the excavator and it’s
attachments. DO NOT overload or serious injury
could result. The attachment may have altered the
machine’s lift capabilities.
• This attachment is for processing materials. DO NOT
use for unapproved purposes.
• DO NOT continuously process oversized materials by
forcing them into the jaw. This will shorten the life of
the attachment.
• If attachment stalls, scale back the amount of material
being processed at one time. Overloading can cause
overheating or damage to the hydraulic system.
• Cycle the cylinder completely when processing.
Fully cycling will allow hydraulic uid to circulate and
prevents overheating.
• Maintain a safe distance.
• NEVER leave the attachment suspended or pass it
over people, occupied vehicles or buildings.
• When working in conned spaces, keep watch on
exposed parts, such as cylinder rods and hoses, to
avoid damage.
• Maintain at least 50 feet (15 meters) between the
attachment and any nearby power lines.
• A LWAY S lower the attachment to the ground and
turn the base machine o when leaving the machine
unattended.
• DO NOT close the jaws on a structure and reverse
the excavator in an attempt to pull down material. This
is dangerous and will damage the excavator and the
attachment.
• Avoid collision of the boom or jaws, especially when
working with limited visibility or inside buildings.
Know the height and reach of the attachment during
operation, transport and when swinging the excavator.
• DO NOT alter factory preset hydraulics. This may void
the warranty.
• DO NOT shear high tensile steel, such as railroad
rail, spring steel, axles and some types of wire. Jaw
damage will result. This type of material breaks when
processed and can become a projectile which could
cause injury or death.

MRP Mobile Rotating Pulverizer Operation & Maintenance Manual | 13
• Use attachment rotation for positioning only. Do not
use if for bending, breaking or prying.
• DO NOT use attachment as a jack hammer or
wrecking ball.
• DO NOT attempt to shear material stuck through the
lower jaw.
• Before shearing thin material, ensure the blades are
sharp and properly adjusted. Thin material may jam
the blades.
• DO NOT apply excavator force at the ends of the
upper shear in an attempt to un-jam the jaws or cut
material that is too large for the shear.

BLEED THE ATTACHMENT HYDRAULIC CIRCUIT
Air must be bled out of the hydraulic circuit prior to operation. Air in the hydraulic system leads to cavitation, oxidation
of the oil and excessive heat. These conditions promote hydraulic oil break-down, contamination, noise, sluggish
operation, reduced component life and potential cylinder damage.
1. Start with the attachment in the vertical position.
2. Set the excavator at idle speed.
3. Slowly open the jaws until a noticeable change in tone of the excavator is heard, indicating a full cylinder. Release
the controls and do not continue to apply full operating pressure to the cylinder.
4. Slowly close the jaws until the cylinder rod is extended approximately 1/4 stroke.
5. Open the jaws to retract the cylinder all the way.
6. Repeat steps 3 and 4. Extend the cylinder a quarter stroke more each time, until you reach full stroke.
7. Slowly cycle back and forth, at least ve times, to full stroke. Be careful not to apply full operating pressure to the
cylinder at this time.
8. Check the base machine hydraulic uid level and ll if necessary.
9. Slowly extend and retract the excavator cylinder to it’s limits. Check for interference between the attachment and

BLADE MAINTENANCE
Before performing blade maintenance, position the attachment on the ground, so that the items being maintained are
close to the ground. When performing maintenance on the upper jaw curl the attachment under the stick.
Wear personal protection equipment at all times. This
includes eye protection, hard hat, steel toe shoes,
leather gloves and hearing protection.
Blades are very heavy. Do not remove a blade if it’s not
supported. The blade may fall and cause injury.
1. Remove the blade bolts and remove the blade from the blade seat.
Note: Bolts may need to be removed by metal arc gouging.
2. Ensure the blade seat is clean.
3. Insert a new blade into the blade seat.
4. Insert the blade bolts and torque as specied in “Inspect / Torque Bolts” on page 18.

TEETH MAINTENANCE
When the jaw teeth are worn or cracking, performance is decreased and the teeth need to be replaced.
Wear personal protection equipment at all times. This
includes eye protection, hard hat, steel toe shoes,
leather gloves and hearing protection.
Jaw teeth are very heavy. DO NOT remove a tooth pin if
the tooth is not supported. The tooth may fall and cause
injury.
1. Locate at, hard ground and place the attachment on the ground.
Note: Work only on the jaw closest to the ground, with the tooth facing up.
2. Remove the bolt and nut that holds the tooth in the jaw.
3. Remove the tooth from the receptacle.
4. Ensure the tooth seat is clean.
5. Insert a new tooth into the receptacle.
6. Insert bolt and fasten the nut to secure the tooth. Torque as specied in “Inspect / Torque Bolts” on page 18.
BUILD UP & HARDSURFACING
Wear personal protection equipment (PPE) at all times.
This includes eye protection, hard had, steel toe shoes,
leather gloves and hearing protection that conforms to
standards ANSI Z87.1 (Eye and Face Protection), ANSI
Z89.1 (Head Protection), ANSI Z41.1 (Foot Protection)
and ANSI S12.6 (S3.19) (Hearing Protection).
Do not use stainless hardsurface rod or other improper
build up and hardsurfacing products. Using improper
products may result in premature wear or cracking of
the base metal.

Guidelines
• Connect the ground pole of the welder to the part to be welded, as close as possible to the welding area. The
ground pole must be connected so that the current does not cross the hinges or the hydraulic cylinder. If the
attachment is mounted on the operation machine during welding, follow the instructions in the base machine
manual to avoid damaging it’s battery or electronics.
• Carefully clean the area where material is to be added.
• Preheat to 302°F - 392°F (150°C - 200°C) and check the temperature frequently.
• Do not place more than two layers.
• Apply material with the grain of the parent material.
• Grind the ends of the ll material beads.
• After welding, cover the area with a heat blanket and allow to cool slowly.
• Carefully follow the application standards recommended by the manufacturer of the ll wire.
