SAFETY
This is the safety alert symbol. It is used to alert you to potential
personal injury hazards. Obey all safety messages that follow this
symbol to avoid possible injury or death.
This safety alert and signal word indicates an imminently
hazardous situation which, if not avoided, will result in death or
serious injury.
This safety alert and signal word indicates a potentially hazardous
situation which, if not avoided, could result in death or serious
injury.
This safety alert and signal word indicates a potentially hazardous
situation which, if not avoided, could result in minor or moderate
injury.
This signal word indicates a situation which, if not avoided, will
result in damage to the equipment.
Always observe safety symbols. They are included for your safety and for the protection of the tool.
Your safety and the safety of others is a direct result of how you operate and maintain your
equipment. Read and 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 decals. Keep
safety decals in good condition. Replace missing or damaged safety decals.
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 specically 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 specic rules for safety and operation.
4 MHP Operating & Maintenance Manual
OPERATIONAL SAFETY
• DO NOT close the attachment on a structure and
reverse the excavator in an attempt to pull down
material.
• If the attachment is not functioning properly, shut
down the machine, follow proper lockout / tag out
procedures and follow proper repair procedures.
• NEVER operate equipment without the original
safety guards in place.
• 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). 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. Lack of proper FOPS may
result in injury or death.
• NEVER operate the excavator without a proper
restraint (seat belt) system in place. Doing so can
create loss of control or ejection from cab.
• NEVER operate the equipment while under the
inuence of drugs, alcohol or other substances
that inhibit mental abilities or reaction time.
• 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.
• 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 and
safety regulations relating to them. If appropriate,
arrange for the safe disposal of the materials by a
qualied person.
• 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 75 feet (23 meters).
• NEVER approach power lines with any part of the
machine. Keep clear at a minimum of 15 feet (5
meters).
• 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 allow riders on the machine. Riders are
subject to serious injuries, such as being struck
by foreign objects or being thrown off the machine.
Riders also distract and obstruct the operator,
resulting in the machine being operated in an
MHP Operating & Maintenance Manual 5
OPERATIONAL SAFETY
unsafe manner. NEVER use the attachment as a
work platform or personnel carrier.
• DO NOT modify LaBounty equipment without
factory authorization. This equipment is designed
to do a specic 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 off 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.
• 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.
• Keep clear of potential pinch points, including the
moving upper jaw, cylinder connections, bucket
linkages and other moving parts.
• 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.
• DO NOT weld on any structural member unless
specically authorized by LaBounty.
• 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.

MODEL DESCRIPTION
MHP series Mobile Hydraulic Pulverizers are designed for quiet, controlled demolition and recycling of concrete
structures. MHP uses crushing teeth to efciently separate rebar from concrete.
DECAL MAINTENANCE
Ensure safety decals are installed and visible. Keep decals clean and promptly replace decals that are
damaged. Replacement decals are available through the LaBounty Service Department. Place replacement
decals in the same position as the original decals.

INSTALLATION
• Use only approved rigging hardware rated
for loads greater than the weight of MHP.
• Hooking Points are for moving the
attachment only. Do not lift other objects or
use MHP in a cable-hung application.
1. Locate at, hard ground (e.g., concrete oor)
for installation. Lift and place the attachment
on the ground as shown. Use blocking if
necessary.
2. Remove the excavator bucket. Follow the
manufacturer’s recommended procedure.
Note: When removing the excavator bucket, plug
hydraulic hoses to prevent contamination.

3. Remove the arm connection and link
connection pins, as shown in Figure 10.
4. Bring the excavator into position, carefully
lining up the stick tip with the MHP mounting
bracket. Pin the stick tip to the MHP mounting
bracket using the pin provided (see Figure 11).
5. Carefully extend the bucket cylinder to move
the bucket linkage. Position the link into the
mounting bracket linkage connection.
Note: It may be necessary to use a lifting device
(overhead hoist, forklift, etc.) to position the link.
6. Pin the linkage connection to the MHP bracket..
