If the attachment is not functioning properly,
you MUST shut the machine down and follow
proper lock-out, tag-out and repair procedures.
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.
Ensure that the cab is equipped with the proper
safety guards for LaBounty applications. In
addition, it is required that the cab be equipped
with an approved Falling Object Protection
Structure (FOPS) when processing materials.
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.
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.
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.

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 replace-
able wear parts have altered the look and improved the performance of
LaBounty® Mobile Shears.
MSD Saber Series™ shear models are currently available for base
machines with operating weights from 20,000- 280,000 lbs (9091
– 130,000 kg) with a range of cutting depths. Both rotating and non-
rotating models are available. Rotating models feature hydraulically-
powered 360º continuous rotation. This option allows the shear jaws to
be positioned to cut at virtually any angle.
MSD Saber Series™ models feature a cylinder-mounted speed valve to
decrease cycle times and increase efficiency. This patented, spool-type
valve design has proven significantly more dependable than cartridge-
type regenerative systems favored by other mobile shear manufactur-
ers. These shears feature high-strength, abrasion-resistant steel
construction to assure long, uninterrupted service – even in the harshest conditions. The main pivot shaft
of every model is manufactured for long life and pivots on Stanley LaBounty’s specially designed bearings.
These shears are designed to draw the material into the jaws to the point where the shear force is greatest,
making them the most efficient cutting tool possible.
Mobile shears can cut a wide variety of materials including I-beams, H-beams, channel iron, steel plate, pipe,
round stock, wire, rebar, concrete, etc. They are ideal for scrap processing, demolition work, road and bridge
reconstruction, and jobs where torching is not feasible or possible.

ATTACHMENT GLOSSARY
Accumulator Used in a hydraulic rotation kit to store hydraulic fluid to drive the rotation motor.
Adjustment Custom-made plates that precisely adjust the lower cutting blades to the upper blades. These plates
Plates make 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).
Boom Pivot Part of the shear mounting bracket that attaches to the excavator’s boom tip (second member mounts).
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 Blade A replaceable component located on the inside of the lower shear cross plate. The cross blade is an
easy-to-replace wear part that reduces maintenance time in the piercing area.
Cross Plate Plate located at the front of the lower shear which ties the two halves of the lower shear together. The
cross blade is contained in the cross plate. Requires regular build-up and hardsurface.
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.
Cutting The blades in the upper and lower shear jaws that shear materials as they bypass. The primary blades are
Blades those in the upper and lower jaws that are nearest to the shear throat. The secondary blades are those
that are farthest from the shear throat.
Cylinder Part of the shear mounting bracket that articulates the tip-up function of the shear. The cylinder
Connection connection attaches to the excavator’s stick cylinder (second member mounts).
End Cap Protects and adjusts the main pivot group of the shear. The end cap is a vital component to the
adjustment of the main pivot group and must not be removed without first consulting the LaBounty
Customer Service Department.
Flow Control A hydraulic component used in a rotating shear that meters out the hydraulic fluid from the rotation
Valve motor. 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
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.

MSD SABER SERIES SHEARS
ATTACHMENT GLOSSARY continued
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. This is a very important
maintenance item.
Guide Blade Thin metal shims used to adjust the guide blade out to maintain the proper guide blade gap. Shims come
Shims in 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.
Gap This 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.
Hub Shims Thin metal, circular shims used in the main pivot group of LaBounty shears. Hub shims provide factory
adjustment of the upper shear for close blade tolerance.
Lifting Points Small holes in the top of the shear to be used when mounting or transporting the shear. There are two
holes near the front of the shear and one lug at the rear. These points must never be used for cable
hanging the shear for cutting operations.
Lower The frontal area of the lower shear through which the upper piercing tip passes. This area contains the
Piercing Area guide blade and the cross blade.
Lower Shear The lower stationary jaw of the shear. The lower shear contains the lower cutting blades, the guide blade,
and the cross blade.
Lower Wear Replaceable, abrasion-resistant wear plates that protect the cross plate of the lower shear.
Plates
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 Pivot High tolerance area of the shear that contains the two main bearings, two thrust washers, main shaft,
Group hub shims and two end caps.
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
Block assembly.
Motor Hydraulic rotation component that drives the turntable bearing or planetary gear box on rotating shears.
Mounting The bracket at the rear of the shear that allows it to be attached to the excavator. For a typical second
Bracket member mount, the mounting bracket pins to the excavator boom tip and stick cylinder.
Planetary Hydraulic rotation component on larger rotating shears. The planetary gear box rotates the body of the
Gear Box shear with hydraulic motor. The output shaft of the component directly drives the turntable bearing of the
rotating shear.
Rear Cylinder Pin that connects the rod end of the shear cylinder to the rear of the shear. The rear cylinder pin must be
Pin greased according to the required maintenance.

Assembly positioning capabilities when processing with the mobile shear.
Saber Tip Bolt-on, two-way indexable piercing tip/wear plate found at the top of the upper jaw.
Shear Hydraulic cylinder that powers the cutting action of the shear. The barrel end of the cylinder attaches to
Cylinder the 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.
Slide Screw Adjustable components installed through both sides of the stick. Aligns and supports the upper shear for
a uniform blade gap.
Speed Valve Regenerative hydraulic valve mounted on the cylinder of LaBounty® MSD Saber Series shears that
increases the shear closing speed (cylinder extend function) when the shear is not under a load, thereby
reducing cycle times and increasing efficiency. Stanley LaBounty uses a spool-type speed valve design for
better durability over cartridge-type regenerative valves.
Swivel Allows continuous hydraulic flow to the shear cylinder during rotation of shear without twisting hoses.
Manifold
Thrust Main pivot group component that is located inside the end caps as a wear part for the main shaft.
Washer
Tie Rod Rod that extends through the center of the main pivot group. The tie rod adds lateral support to the main
pivot group.
Throat Area of both the upper and lower jaw near the main pivot where the primary blades are located. The
throat area is the optimum area for shearing material. The shear is most powerful on the primary blades
nearest the pivot point.
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. This bearing is sometimes called a slewing ring.
Upper Head Mounting bracket portion of a rotating shear. Attaches to the turntable bearing that attaches to the rear of
the shear stick. The upper head contains the hydraulic manifolds and the swivel manifold.
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 of
the shear.
Wear Parts Consists of the cutting blades, guide blade, cross blade, and Saber Tip™. These parts can be easily
replaced to refresh the System wear areas of the shear jaws. Dramatically increased surface areas on
these wear parts provide better wear and less downtime for maintenance.

FLOW AND PRESSURE REQUIREMENTS
The following table prvodes the MSD Saver Series Mobile Shear flow and pressure requirements for the open and close
function. Please note that all models include speed valves; also note that these calculations are theoretical and that actual
cycle times will vary depending upon the specific excavator’s hydraulic efficiency, possible back pressure in the system,
operator competency, etc. These cycle times are calculated with not material in the jaws. The cycle times will be longer
when maximum shear force is required (shear will go out of “speed valve mode”).

NOTICE
•Rotation Circuit- 8-12 GPM @ 2000- 2500 PSI. A 1/2"case drain line going from the hydraulic rotation
motor to the excavator’s hydraulic tank is required to relieve back pressure.
•Pump summation or dual pump flow is recommended for shear munting second-member on most
excavators. Due to the increase in flow, there may be a requirement to add larger hydraulic lines or dual
lines up the boom to minimize back pressure, reduce heat and maximize shear performance.
