UNDERSTAND SIGNAL
WORDS
When you see the following symbols and signal words
on your equipment or in this manual, be alert to the
potential for personal injury or equipment or property
damage. Follow recommended precautions and safe
operating practices.
Indicates immediate hazards that WILL result in
severe personal injury or death.
Indicates hazards or unsafe practices that CAN
result in severe personal injury or death.
Indicates hazards or unsafe practices that could
result in personal injury.
INTRODUCTION
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 specifically
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 specific rules for safety and
operation. NOTICE
Indicates notes of importance to a procedure or
part.

Introduction to Safety Section 1 Page 3
MSD 7R SHEARS
If the attachment is not functioning properly, you
must shut the machine down and follow proper
lockout, tag, and repair procedures.
NEVER operate equipment without the original
equipment safety guards in place, which include
ROPS (Rollover Protective Structures and FOPS
(Falling Object Protective Structures) cabs. A special
applications kit (consisting of a 1/2” thick Lexan
front door and 1/4” top and rear windows) must
be installed on a loader mounted with a shear;
doing so prevents objects from entering the cab
opening during operation. Use only the approved
parts in the kit. Follow the installation instructions
exactly. Unapproved window changes or other
modifications can cause loss of protection and
result in injury or death.
DO NOT process or handle material with the
attachment over the operator’s cab.
DO NOT attempt to shear brittle materials such as axles
and railroad rail. Brittle material breaks or shatters instead
of shearing. The material being processed could become
a projectile and cause injury or death. DO NOT process
any material in any position that may propel it toward
operator, other workers, buildings or equipment.
DO NOT close the attachment on a structure and
reverse the excavator in an attempt to pull down
material.
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 (22.9 meters).
NEVER approach power lines with any part of the
machine. Keep clear at a minimum of 15 feet (5
meters).
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. Carry loads in recommended positions for
maximum stability. Use the recommended excavator
counterweight. Use short slings and lift the load only
as high as necessary.
DO NOT allow riders on the machine.
SAFETY SUMMARY

MSD 7R SHEARS
Page 4 Section 1 Introduction to Safety
NEVER remove any pins unless the attachment is on
the ground and blocked up or serious injury or death
could result. Metal chips or debris may fly when a
connecting pin is struck. Use a brass drift when striking
pins and always wear protective clothing and proper eye
protection. Pins may fly when struck with force to drive
them in or out. Keep people clear when removing or
installing pins.
NEVER operate equipment without the original
equipment safety guards in place. If the cab glass
is missing or damaged, check with your dealer or
manufacturer for proper replacement.
Under no circumstances should any modifications
be made to LaBounty equipment without factory
authorization.
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. DO
NOT work under a machine that is supported only by
a jack.
DO NOT let hot hydraulic oil get in contact with the
skin as it could cause severe burns. Wear adequate
protective clothing and safety equipment. DO NOT
tamper with any hydraulic line or component while
it is pressurized. Escaping fluid under pressure can
penetrate the skin, causing serious injury. Relieve
pressure before unhooking hydraulic or other lines.
Tighten all connections before applying pressure.
Keep hands
and body away from pinholes and nozzles
which eject fluids under high pressure. Use a piece of
cardboard to search for leaks. If ANY fluid is injected
into the skin, seek immediate medical assistance.
SAFETY SUMMARY continued
Before leaving the operator’s seat, you MUST do the
following:
1. Close the jaws of the shear.
2. Rotate the shear to a horizontal position.
3. Lower the lift arms fully.
4. Engage the brake.
5. Stop the engine.
6. Raise the seat bar.
7. Move the pedals until both pedals are locked.
DO NOT weld on any structural member unless
specifically authorized by LaBounty. Any unauthorized
welding or welding procedures will void the warranty,
and may cause structural failure or result in personal
injury.
ALWAYS wear close-fitting clothing and safety
equipment appropriate to the job. Safety equipment
should be worn at all times when viewing, operating,
or maintaining the attachment to prevent injury.
Safety equipment includes eye protection, hard hat,
steel toe shoes, gloves, and hearing protection.
Keep clear of all potential pinch points, including
the moving upper jaw, cylinder connections, bucket
linkages or other moving parts.
Before operating the attachment, read and
observe all safety instructions in the Operation
and Maintenance sections of this manual. If you
are unfamiliar with any operation or maintenance
procedure, seek instruction before proceeding.

MODEL DESCRIPTION
Since LaBounty mobile shear technology was introduced, many changes have taken place. A wide selection
of models and sizes are now available. Product refinements like 360º continuous rotation, high-performance
reversed cylinders, tougher steels, and bolt-on replaceable wear parts have altered the look and improved the
performance of LaBounty Mobile Shears.
MSD Mobile Shears are available in three basic models—Standard Stick, Integral Shroud and Integral Shroud
with 360º Option (R). These models are described in this section.
Models are available for base machines from 7,500 to 400,000 pounds with a range of cutting depths from 10”
to 76” available. Optional 360º continuous rotation provides easy, accurate cutting at all angles.
High tensile, high alloy, abrasion-resistant steel construction assures long, uninterrupted service—even in the
harshest conditions. The main pivot shaft of every model is induction-hardened, ground for long life and pivots
on LaBounty’s specially designed bearings.
Mobile shears can cut a wide variety of materials including I and H beams, other building materials, steel plate,
round stock, wire, rebar and concrete. They are ideal for scrap processing, demolition work, road and bridge
reconstruction and in jobs where torching is not possible.
FEATURES
•Added reach reduces machine movement and wear
and greatly reduces the need for arm mounting—safety
is increased
•Made with high-strength, abrasion-resistant steel for
durability
•Replaceable wear parts for easy maintenance
•Four-way indexable blades
•Installs in as little as two hours
•At-factory upgrading and rebuilding services available

ATTACHMENT GLOSSARY
Adjustment Custom-made plates that precisely adjust the lower cutting blades to the upper blades. These plates make
Plates it possible to achieve a uniform blade gap on the shear.
Apex The point where the primary and secondary cutting blades come together.
Blade Gap The gap between the upper and lower cutting blades as the blades bypass. A very important item that
must be maintained regularly to prevent material from jamming in the blades.
Blade Shims Thin metal shims used to adjust the position of the lower cutting blades to maintain a proper blade gap.
Blades should never be shimmed out farther than 0.13" (3.3 mm).
Build Up Welding process where worn off parent material is replaced with new metal. A very important maintenance
procedure that must be performed regularly throughout the life of the shear.
Control Valve Used in the hydraulic rotation kit to direct flow to the accumulator and back to the hydraulic motor.
Manifold
Cross Pattern A method of torquing a circular pattern of bolts down to achieve proper seating. The technique pattern,
Technique based on a clock face pattern, would follow the order of 12, 6, 11, 5, 10, 4, 9, 3, 8, 2, 7, 1.
Crossover A hydraulic component used in a rotating shear that limits the amount of hydraulic pressure sent to the
Relief Valve rotation assembly. The crossover is preset at the factory and must not be tampered with.
Flow Control A hydraulic component used in a rotating shear that meters out the hydraulic fluid from the rotation motor.
Valve The flow control should be set to limit the rotator from spinning faster than 1- 2 revolutions per minute.
Front Cylinder The pin that attaches the shear cylinder barrel end to the upper shear.
Pin
Front Wear The area of the upper that contacts the guide blade; it is located on the opposite side of the upper shear
Plate from the cutting blades.
Grain of The direction that the parent material was initially rolled at the steel mill. It is very important when
Material hardsurfacing any part of the shear to weld with the grain of the steel. Cross-grained hardsurfacing has the
tendency to start cracks in the base material.
Guide Blade A replaceable component located opposite the cutting blades in the lower shear. The main purpose of the
guide blade is to support the upper shear during the cutting cycle.
Guide Blade Thin metal shims used to adjust the guide blade out to maintain the proper guide blade gap. Shims come in
Shim Set a designated set that determines when the guide blade will be indexed or replaced.
Guide Blade The gap between the front wear plate and the guide blade as the upper shear is cycled into the lower. This
Gap is an important maintenance item to ensure longevity of the shear’s structure.
Hardsurface Welding process for protecting the parent material of the shear jaws. The hardsurface acts as a wear
surface.

MSD 7R SHEARS
About the Attachment Section 2 Page 5
ATTACHMENT GLOSSARY
Lower Shear The lower stationary jaw of the shear. The lower shear contains the lower cutting blades, the guide blade,
and the cross blade.
Main Bearing Hardened bushings that the main shaft of the shear rotates on during operation. There are two main
bearings, bolted in on both sides of the main pivot group.
Main Shaft The shaft on which the upper shear pivots causing the shearing action of the attachment.
Manifold Hydraulic block that directs the excavator’s hydraulic flow to the shear cylinder and rotation assembly.
Block
Motor Hydraulic rotation component that drives the turntable bearing or planetary gear box on rotating shears.
Nose Plate Steel plate across the front of the lower shear jaw. The profile of the nose plate is a very important
maintenance item that must be built up and hardsurfaced to prevent wear of the parent material.
Primary The cutting blades in the shear jaws closest to the shear throat. There is a primary blade in both upper and
Blades lower shear jaws.
Rear Cylinder Pin that anchors the butt end of the shear cylinder inside the rear of the shear. The rear cylinder pin must be
Pin greased according to the instructions in this manual.
Rotation Hydraulic drive assembly allows full 360° continuous rotation of the shear. This option gives greater
Assembly positioning capabilities when processing with the mobile shear.
Secondary The cutting blades in the shear jaws farthest from the shear throat. There is a secondary blade in both the
Blades upper and lower shear jaws.
Shear Hydraulic cylinder that powers the cutting action of the shear. The barrel end of the cylinder attaches to the
Cylinder shear’s upper jaw and the rod end attaches to the rear cylinder lugs. The cylinder rod stays protected from
damage inside the shear.
Shear Stick The main body of the shear that includes the lower shear. This weldment must be regularly inspected for
damage.
Swivel Allows continuous hydraulic flow to the shear cylinder during rotation of shear without twisting hoses.
Manifold
Turntable Rotary gear bearing used in rotating shears. It is mounted to the shear stick and is driven by hydraulic
Bearing components in the upper head or mounting bracket. It is sometimes called a slewing ring.
Upper Shear Movable jaw of the shear that contains cutting blades, the Saber Tip, and the wear area for the slide pucks.
The shear cylinder articulates the upper shear into the lower shear to perform the cutting action.

SHEAR MOUNTING FOR
SKIDSTEER MOUNTS
The shear is equipped with a mounting plate that will
mount to the loader in the same way as the origi-
nal equipment. See Figure 3-1. Refer to the loader
manual for specific mounting instructions.
SHEAR MOUNTING FOR
STICK (OR BOOM) MOUNTS
1. Locate level, firm ground, such as a concrete floor,
for installation. Place the shear on the ground with
the mounting bracket facing the excavator (figure
3-2). It may be necessary to block up the rear end of
the shear to allow the stick or boom tip to be aligned
with the mounting bracket. For second member, or
boom mounts, it may be necessary to place the
shear on the ground upside down with the mounting
bracket facing away from the cab (Figure 3-3).
2. Remove the bucket or other attachment following
the manufacturer’s recommended procedure. For
second member, or boom mounts, the stick will also
need to be removed before installing the shear.
3. Take care to plug the hydraulic hoses when dis-
connected to prevent contamination from entering
the hydraulic system.
4. Walk the excavator into position, lining the stick
into the stick pivot of the attachment (Figure 3-4).
5. Pin the excavator’s stick and attachment stick
pivot together.
6. Use the bucket cylinder, if necessary, to align
the excavator bucket linkage with the linkage con-
nection of the shear bracket. Pin this connection
together.
7. Double-check all pins, collars, and related fasten-
ers to ensure they are properly installed and tight-
ened.
8. See the electrical and hydraulic installation in this
section, pages 3-4, and 3-5.

SHEAR REMOVAL FOR
STICK MOUNTS
1. Locate flat, hard ground. With the bottom of the
shear facing the operator, set the shear on the
ground (figure 3-5).
2. Use blocking to support the bucket linkage and
remove the link pin.
Removal of any pin connecting the shear to the
base machine can be hazardous. Never remove
any pins unless the shear is properly supported
on the ground (or blocked up if necessary) or
serious injury could result.
3. Fully retract the bucket cylinder after it is de-
tached from the shear mounting bracket (figure 3-6).
4. CAREFULLY remove the hydraulic lines from the
shear.
Trapped hydraulic pressure may be present after
base machine is turned off. Extreme caution
must be taken when removing shear hydraulic
hoses or injury or death could result.
5. Cap the open fittings and hose ends to prevent
contamination of the hydraulic system.
6. Stand clear and instruct the operator to set the
shear flat on the ground (figure 3-7).
7. At this point, be extremely sure the shear is stable
before releasing the weight of the shear.
8. Remove the stick pivot pin from the shear.

HYDRAULIC INSTALLATION FOR STICK AND SKIDSTEER
MOUNTS
Use the following instructions and the skidsteer examples on the following pages to set up your shear hy-
draulics properly.
1. Connect auxiliary hydraulic lines from the base machine to the hydraulic connections at the rotating head of
the shear. This circuit may have been installed from the factory or may require installation.
2. After connecting the auxiliary hydraulic circuit from the base machine to the shear, install an additional 1/4”
diameter case drain line.
3. Lift the boom and slowly engage the rotate function and open and close functions. Watch for hydraulic oil
leaks and interference.
4. Follow the hydraulic start-up procedure as described in this manual.
When installation is complete, slowly move the shear
through its full range of motion. Check for interference
between the shear and the base machine. Contact
dealer/factory immediately if any interference occurs
The same auxiliary control device will be used for the
open and close circuit and the rotate circuit. To oper-
ate the rotate function, the electrical switch will need
to be activated.
