SAFETY SUMMARY
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.
MSD SABER SERIES SHEARS
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 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 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.

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 refi nements like 360º continuous rotation, highperformance reversed cylinders, tougher steels, and bolt-on replaceable 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 hydraulicallypowered 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 effi ciency. This patented, spool-type
valve design has proven signifi cantly more dependable than cartridgetype 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 effi cient 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.

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 fl ow 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 fi rst consulting the LaBounty
Customer Service Department.
Flow Control A hydraulic component used in a rotating shear that meters out the hydraulic fl uid from the rotation
Valve motor. The fl ow 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.

FLOW AND PRESSURE REQUIREMENTS
The following table prvodes the MSD Saver Series Mobile Shear fl ow 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 specifi c excavator’s hydraulic effi ciency, 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 fl ow is recommended for shear munting second-member on most
excavators. Due to the increase in fl ow, 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.

SHEAR MOUNTING
PROCEDURE
Take note whether yours is a second member or a
third member installation. A second member mount
is where the shear replaces the excavator stick; a
third member mount is where the shear replaces
the bucket.
1. Place the shear upside down on the ground with
blocking to keep the shear level. Locate fl at, hard
ground for installation.
2. For a second member mount, remove the excavator stick following the manufacturer’s recommended
procedure.
3. For a third member mount, remove the bucket or
other attachment following manufacturer’s recommended procedure. To prevent contamination of the
hydraulic system, plug the hydraulic hose when they
are disconnected.
NOTICE
It may be necessary to lift the rear of the shear
into position to allow boom pivot pin installation
on second member mounts.
4. With the jaws of the shear facing the excavator,
walk the excavator into position, aligning the excavator’s boom or stick into the boom pivot or stick connection of the shear bracket (see Figure 3-1).
5. For second member mounts, pin the shear boom
pivot to the excavator boom using the excavator
boom pin (second member). For third member
mounts, pin the stick tip to the stick connection using the pin provided by LaBounty.
6. Instruct the operator to slowly pick the shear up
into a position where there will be enough clearance
to pin the other connection of the shear mounting
bracket (see Figure 3-2).

SHEAR MOUNTING PROCEDURE continued
7. Extend the cylinder rod or bucket linkage and move into position as necessary to pin this connection. Install
shear supplied pin. It may be necessary to use a lifting device (overhead hoist, forklift, etc.) to position the
cylinder or linkage correctly.
8. Connect the hydraulic hoses to the manifold located on each side of the head. Remember to cap all hydraulic hoses and fi ttings immediately to prevent contamination of the hydraulic system. Tighten the bolts to the
proper torque (refer to Split Flang Fitting Torque Tables on page 8-26).
9. On rotating models the following procedures are to be followed.
a. After installing a hydraulic circuit on the excavator, install additional hydraulic lines up the boom—
these will include two 1/2” (13 mm) diameter feed lines and one 1/2” (13 mm) diameter case drain
line. These will terminate at the end of the boom.
b. Install jump lines from the above hydraulic lines to the shear bulkhead or manifold fi ttings. Please
refer to the parts catalog for specifi c fl ow and pressure requirements; if in doubt, call Service (800-522-
5059).
10. Check to make sure all collars, fasteners, and other connecting hardware are secure before proceeding.
11. Lift the boom and slowly try the shear rotate function and shear open and close function (see Figure 3-3).
Watch for hydraulic oil leaks.
NOTICE
When installation is complete, slowly curl the
shear to tuck it under the boom. Check for
interference. Contact factory immediately if
any interference occurs.

MOBILE SHEAR START-UP PROCEDURE
Air must be bled out of the cylinder prior to operation of the shear. Trapped 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. This procedure will
need to be followed upon installation, after hydraulic repairs have been made, or when a shear has been
stored or idle for an extended period of time. Make sure the shear cylinder is either fully retracted or extended—if not, mechani-cally place into either of these positions (loosen end plugs or caps on the manifold or fi ttings to relieve air pressure to the shear cylinder. Position the shear so the cylinder is as horizontal as possible.
Sett the excavator at idle speed or slightly above idle speed.
WITH CYLINDER FULLY RETRACTED
1. Slowly fi ll the rod end of the cylinder (open the shear) until a noticeable change in tone of the excavator is
heard, indicating full cylinder. Do not operate to the machine’s full operating pressure.
2. Change direction of oil fl ow; slowly fi ll the bore end of the cylinder (close the shear) until the rod is extended
approximately 1/4 of stroke.
3. Retract the cylinder rod all the way.
4. Repeat steps 2 and 3, extending rod to approximately 1/2 stroke, then 3/4 stroke, then full stroke.
5. When cylinder is full of oil, slowly cycle cylinder rod back and forth at least fi ve times through full stroke. Do
not operate to the machine’s full operating pressure.
WITH CYLINDER FULLY RETRACTED
1. Slowly fi ll the bore end of the cylinder (close the shear0 until a noticeable change in tone of the excavator is
heard, indicating full cylinder. Do not operate to the machine’s full operating pressure.
2. Change direction of oil fl ow; slowly fi ll the rod end of the cylinder (open the shear) until the cylinder rod is
retracted approximately 1/4 stroke.
3. Extend the cylinder rod all the way.
4. Repeat steps 2 and 3, retracting cylinder rod to appoximately 1/2 stroke, then 3/4 stroke, then full stroke.
5. When cylinder is full of oil, slowly cycle cylinder rod back and forth at least fi ve times through full storke. Do
not operate to machine’s full operating pressure.
6. Slowly cycle the cylinder fi ve or more times reaching machine’s normal operating pressure at end of each
stroke, open or close. Listen for unusual noise and check for any hydraulic leaks.
NOTICE
After the cylinder has been bled and drained of air,
check the excavator hydraulic fl uid and fi ll to the
proper level.

MOBILE SHEAR REMOVAL
PROCEDURE
1. Position shear under the boom of the excavator as
far as the stick cylinder will extend and lower shear
to the ground.
2. Use blocking to support the stick cylinder from
the excavator boom.
3. Remove the stick cylinder pin from the shear
mounting bracket.
4. Fully retract the stick cylinder as it is unattached
from the shear mounting bracket.
5. Cycle the upper jaw closed far enough to allow
the upper to lay fl at on the ground with the rest of
the shear. The object of this is to create as many
possible shear contact points with the ground.
6. Cycle all controls with the excavator off to relieve
any trapped pressure.
7. Carefully remove the jump-lines at the shear manifold.
8. Plug the open manifold ports and hose ends with
pressure plugs to prevent contamination of the hydraulic system.
9. At this point, be extremely sure that the shear is
stable and tension to the boom pivot pin is released
before unpinning the boom pivot pin and releasing
the weight of the shear.
10. Remove the boom pivot pin from the shear.

See Figure 3-4. Trapped hydraulic pressure may
be present after the base machine is shut off.
Extreme caution must be taken when removing
attachment hydraulic hoses or possible injury or
death could result.
SHEAR STORAGE
1. Block the shear up off the ground using wood
blocking.
2. Grease the pins and machined bores of the
mounting bracket of the attachment. Apply a generous amount of grease to the shear blades, cylinder
rod and all other exposed unpainted surfaces.
NOTICE
Watch the boom to attachment pivot for any interference. If interference is present DO NOT force the
attachment under any further. Block the attachment
up before it interferes with the boom, or stop.

INSTALLATION
if equipped
BEFORE GETTING STARTED
1. Have the Parts Catalog for the shear and the
installation manual on hand for reference. The parts
information for the Internal Rotation Control System
is included in it.
2. Check if the following items exist on the base
machine:
a. A preferred control switch other than the
foot switch provided (see Foot Pedal Switch Installation).
b. One -8 (1/2” SAE JIC type) adapter to tap
into base machine reservoir or return line.
c. One -8 (1/2” SAE) hydraulic line plumbed
from the base machine’s hydraulic return to the end
of the boom (if the shear is mounted in place of the
stick) or the stick if the shear is mounted in place of
the bucket.
d. One 15 amp circuit breaker or fuse.
ELECTRICAL INSTALLATION
INTERNAL ROTATION
CONTROL SYSTEM
if equipped
LaBounty provides a three-position foot switch with
the Internal Rotation Control System. Alternative
types of switches may be used in place of the provided foot switch, if preferred. Contact your LaBounty dealer for information on operating the control
valve. Any of the following can be used:
a. Joystick handle equipped with a single
pole/double throw momentary three-position rocker
switch;
b. Two joystick handles each equipped with a
single pole/single throw momentary rocker switch or
push button switch;
c. a single pole/double throw three-position
momen-tary toggle switch mounted to the control
lever with a fabricated bracket.
INSTALLATION
1. Place the foot switch or other preferred control
switch inside the cab in a convenient location for
operating.
2. Route the electrical cord with the plug up the
boom (and stick if the shear replaces the bucket).
Secure the cord to an existing hydraulic line using
tie straps. Attach the green wire of this cord to the
base machine chassis to ground the system.
3. Run a 14-gauge wire from the base machine’s DC
voltage power supply and connect it to a 15-amp
circuit breaker fuse. The power source should be
accessory side or a similar source that provides voltage only when the starter key switch is in the “ON”
position, and should have a 5-amp minimum rating.
4. Connect a 14-gauge wire from the circuit breaker
or fuse to the red wire of the electrical cord running
up the boom to the electrical plug. Connect another
14-gauge wire from the circuit breaker or fuse to
this red wire of the electrical cord coming from the
foot switch. The red wire from the electrical plug
and the red wire from the foot switch can be connected.
5. Connect the black wire from the boom cord to
the black wire from the foot switch cord. Connect
the white wires in the same way. The green wire
from the foot switch cord will not be used.
To prevent electrical shock, short, or accidental
start-up, do not connect to the power source
until the entire system is installed.
NOTICE
Make sure to complete all installation procedures described in this section before starting the machine.
Operating the shear before proper installation is
complete may cause damage to the base machine.

1. Always relieve all hydraulic pressure of the base machine
by working the controls in all directions with the engine off
before beginning work on any hydraulic component. See
Figure 3-6.
2. Shut off the base machine and check the hydraulic sys-
tem pressure. It should be zero PSI.
3. Hydraulic oil becomes hot during operation. DO NOT
let hydraulic oil get in contect with the skin as it will cause
severe burns.
FIGURE 3-6
4. Whenever hydraulic lines are disconnected, hoses must
be capped and ports much be plugged to prevent contamination of the hydraulic system.
5. Install a 1/2” diameter hydraulic line (customer supplied)
from the attachment’s return fi tting, located in the right
hand hydraulic manifold, to the base machine’s hydraulic
reservoir or return line. Secure the line properly to the excavator boom and stick.
Escaping fl uid under pressure can penetrate the skin
causing serious injury. Relieve pressure before disconnecting hydraulic lines. Tighten all connections before
applying pressure. Use a piece of cardboard to search
for leaks. If ANY fl uid is injected into the skin, seek immediate medical assistance.
