Indicates important procedures.
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 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 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.
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
MSD Legend Series Operation & Maintenance Manual | 5
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.
• 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
inuence of drugs or alcohol.
• 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
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
specically 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.

OPERATING TIPS
• The control levers should be moved in a gradual, deliberate way rather than with jerky, abrupt movements. Jerky
movements will provide a rough ride in the cab and could give the appearance of instability.
• Avoid handling long, heavy materials o center. Excessive weight held out to one side can force the attachment to
rotate or “Back-drive”. Back-driving puts increased strain on the rotation system and, if done continually, can lead to
rotation component problems. The rotator is for positioning only.
• Do not apply excavator force or weight at either end of the upper shear in an attempt to un-jam the shear or to cut
materials that are too large.
• Avoid handling long, heavy materials o center.
18 | MSD Legend Series Operation & Maintenance Manual
• When processing oversized material, make partial bites to start the breakage and then back o before making the
next partial bite. This will allow the broken material to fall away between bites.
• When processing any rigid member, use the rotator to square the jaws to the cut. If the jaws are not square, the
rotator will back-drive to adjust to the cut.
• When shearing large steel members, such as I-beams or tubing, try doing it in two cuts rather than one. Pierce the
material about halfway through with the rst cut, and then nish it o with the second cut.
• The shear jaws are best capable of processing light, thinner gauge materials immediately after performing
blade maintenance. When processing larger materials, the condition of the blades are not as critical. See “Blade
Maintenance” on page 26.
• Sort your scrap to get the highest capacity from the attachment.
• Start processing smaller materials and work up to larger materials. This will help you learn the limitations of the
machine and will allow the machine to warm up properly.
• Understand that the attachment does have limits. Sometimes it may be necessary to downsize very large material
by another method before the attachment can process it eectively.
• Cut material deliberately. Do not plunge the jaws into a pile of material and cut indiscriminately.
• Keep the attachment properly maintained. Jaws with excessive blade gaps or dull teeth are much less eective.
Lack of maintenance can lead to greater problems and potential downtime.
• Only use the force of the cylinder to cut material. Do not attempt to apply other forces on the shear to aid in material
processing.
• The rotation function is for positioning only. Do not use it for bending, breaking or prying.
BLEED THE SHEAR HYDRAULIC CIRCUIT
Air must be bled out of the hydraulic circuit prior to operation. Air in the 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 shear 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
the excavator boom or stick. Check the hydraulic lines that connect to the attachment. Ensure they are not rubbing
or becoming damaged in any way. Contact your dealer immediately if interference occurs.

BLEED INSITE
1. Remove the cover from the InSite box.
2. Connect a bleed hose (part number 227831) to the CW and CCW bleed couplers on the InSite control box. Be aware
that the shear may move slightly when connected.
Note: If you have a non-rotating shear, you will not have CW and CCW bleed couplers.
Do not connect the CW or CCW connections to the ROD or
BORE connections. Seal damage and unexpected movement
may result.
Bleed Hose
CCW Bleed Coupler CW Bleed Coupler
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).
3. Power up the excavator and make one full rotation in both the clockwise and counter clockwise directions.
4. Power down the excavator and relieve hydraulic pressure.
5. Disconnect the bleed hose from the CW and CCW bleed couplers.
Do not connect the CW or CCW connections to the ROD or
BORE connections. Seal damage and unexpected movement
may result.

7. Power up the excavator and fully open and close the shear jaws.
8. Power down the excavator, relieve hydraulic pressure and remove the bleed hose from the bleed couplers.
CHECK FOR LEAKS
Keep hands and body away from pinholes and nozzles which
can penetrate the skin, causing serious injury. Use a piece of
cardboard to search for leaks.
1. Starting at idle, or low hydraulic ow, operate the shear.
2. Visually inspect the attachment for leaks.
3. Set the hydraulic power supply to full operation ow and pressure.
4. Visually inspect the attachment for leaks.
5. Check the hydraulic oil reservoir and ll as stated in the excavator manual.
