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 specifi 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 specifi c rules for safety
and operation.

SAFETY SUMMARY
BUCKET LINKAGE SHEARS
IF THE ATTACHMENT IS NOT FUNCTIONING
PROPERLY, YOU MUST SHUT THE MACHINE
DOWN AND FOLLOW PROPER LOCKOUT, TAG,
AND REPAIR PROCEDURES.
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.
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 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.
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
fl 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 fl y
when struck with force to drive them in or out. Keep
people clear when removing or installing pins.

BUCKET LINKAGE SHEARS
SAFETY SUMMARY continued
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 modifi cations
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 fl uid 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 fl uids under high pressure. Use
a piece of cardboard to search for leaks. If ANY fl uid
is injected into the skin, seek immediate medical
assistance.
ALWAYS wear close-fi tting 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.
DO NOT weld on any structural member
unless specifi cally authorized by LaBounty. Any
unauthorized welding or welding procedures will
void the warranty, and may result in personal injury.

BUCKET LINKAGE SHEARS
MODEL DESCRIPTION
The BLS Bucket Linkage Shears are designed to mount directly to
the excavator stick, in place of the bucket. The shear is pinned to the
stick tip and bucket linkage and is opened and closed by activating the
excavator bucket circuit. The lower shear stick pins to a mounting pad
which is welded to the bottom of the excavator stick (the same type
of pad used with LaBounty Grapples and Concrete Pulverizers). Models are available for base machines from 40,000 to 100,000 pounds
(18,000 to 45,000 kg).
The BLS series is designed to be used as a simple shear to process
lighter gauge scrap than a comparable MSD series shear. It is ideal
for processing rebar, angle, “I” beams, pipe, and other ferrous and
non-ferrous scrap. Applications for this tool include auto salvage yards,
scrap yards, and light demolition work.
The BLS series features four equal-sized, four-way indexable cutting
blades. This means that the blades can be rotated to use all four edges.
The single guide blade in the lower jaw and the wear plate on the up-
per shear keep the jaw in alignment during the cutting process.
BLS shears are constructed of high tensile, abrasion-resistant steel
that assures long, uninterrupted service – even in the harshest conditions. The main pivot shaft of every model is manufactured for long life
and pivots on LaBounty’s specially designed bearings. The lever arm
of the upper shear is designed to maximize the cutting force for the
excavator on which it is mounted.
FEATURES
• Combines maximum cut-
ting strength and reach
with minimal weight
• Constructed of high
tensile, abrasion-resistant
steel for long life
• Replaceable wear parts for
easy maintenance
• Four-way indexable blades
• Installs in as little as two
hours
• At-factory upgrading and
rebuilding services available for extended life

ATTACHMENT GLOSSARY
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).
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.
Cutting The blades in the upper and lower shear jaws that shear materials as they bypass. The primary
Blades blades are 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.
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 fi rst consulting the
LaBounty Customer Service Department.
Front Wear A replaceable wear plate that is located on the opposite side of the upper shear weldment of
Plate the cutting blades. It wears on the guide blade during shearing. this is a very important
maintenance item; it must be replaced when worn.
Grain of The direction that the parent material was initially rolled at the steel mill. It is very important
Materials when 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. 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 Shims come 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
Gap lower. 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.
Link The mounting connection where the upper shear is pinned to the bucket linkage of the
Connection excavator. A pin is provided with the shear to make this connection.
Lower The frontal area of the lower shear through which the upper piercing tip passes. This area
Piercing Area contains the 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.
Main Hardened bushings that the main shaft of the shear rotates on during operation. There are two
Bearing 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
Group shaft, hub shims, and two end caps.
Main Shaft The shaft on which the upper shear pivots causing the shearing action of the attachment.
Nose Plate Plate located at the front of the lower shear jaw that ties the two halves of the lower shear
together. This plate requires regular build-up and hardsurface.
Piercing Tip Replaceable wear part that is welded into the tip of the upper shear.
Stick The main body of the shear that includes the lower shear. The stick fastens to the mounting
pad on the excavator stick and must be regularly inspected for damage.
Stick The mounting connection where the lower shear and stick are pinned to the end of the
Connection excavator stick. A pin is provided with the shear to make this connection.
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.
Upper Shear Movable jaw of the shear that contains cutting blades, the piercing 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.
