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

SAFETY SUMMARY
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.
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 allow riders on the machine.
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.
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.

SAFETY SUMMARY
CONTINUED
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.
See Figure 1-3. 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.
Page 4 Section 1 Introduction to Safety
DO NOT weld on any structural member unless
specifically authorized by LaBounty. Any unauthorized welding or welding procedures may 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 introduced the Contractor’s Grapple, many changes have taken place. A wide selection of models and sizes are now available—product
refinements have altered the look and performance
of LaBounty grapples.
HDR GRAPPLE
Contractor’s grapples are available in two basic
models—HDR and TW with sizes ranging for base
machines from 25,000 to 240,000 pounds (11,000
to 109,000 kg) and openings from 88 to 150 inches
(2.2 to 3.8 meters).
HDR Grapples are designed for versatility. With a
two tine upper (movable) jaw and a three tine lower
(stationary) jaw, they are unequalled in demolition,
scrap recycling, rip-rap, land clearing, log and pipe
handling and quarry applications. For scrap handling
applications, pointed tine tips are available to provide better penetration into the scrap pile.
TW Grapples feature a four tine upper (movable) jaw
and a five tine lower (stationary) jaw. They are designed to handle waste, refuse, and large volumes of
loose materials.
FEATURES
• Patented design combines highest payload-todead-weight ratio allowing handling and lifting more
material.
• Replaceable wear parts for easy maintenance.
• Installs in as little as 15 minutes.
• Factory upgrading and rebuilding services available
for extended life
• High-tensile, abrasion-resistant steel construction
assures long, uninterrupted service —even in the
harshest conditions.

BEFORE YOU START
KNOW YOUR SAFETY PROGRAM
1. Read and understand the safety section of this
manual and the base machine manual.
2. Know the employer’s safety rules for your job.
Consult your foreman for specific instructions and
safety equipment required.
3. Learn the traffic rules at the work site.
4. Know the hand signals used on the job and who
is responsible for signaling. Take signals from only
ONE person.
KNOW YOUR EQUIPMENT
• Learn the location and function of all controls.
Test all controls to ensure proper operation. If any
malfunctions are found, shut the machine down and
report the malfunction for repair.
• Be familiar with the safety devices on the machine,
indicators, warning devices and caution instructions.
They will alert you to conditions that may make it
hazardous to continue operating.
• Wear proper protective clothing including hard
hat, safety shoes, ear protectors, reflective clothing,
safety goggles and work gloves. Loose clothing
can get caught in machinery and cause injury.
Wrist watches, rings and other accessories can be
dangerous, as well.
• Know the clearances in the work area.
Page 2 Section 4 Operation
FIRST THINGS FIRST
1. Ensure all safe viewing distance decals are
installed and legible; contact LaBounty for
replacements as required.
2. Have a DAILY Safety Dialog with all those with
whom you work. Inform them of any out-of-theordinary work that may be planned for the day.
Remind them of the safe working distance.
3. Clear the area; inspect. ALWAYS look out for
others. In any work area, people constitute a
serious safety hazard. Before operating, walk
completely around the machine to be sure there
are no workers next to, under or on it. Warn nearby
workers that you are starting up; DO NOT start up
until they are out of danger.
4. Each day before starting, visually inspect the
machine by walking around it entirely; check the
location of cables, gas lines, and water mains
before any operations. Make sure work site
footing has sufficient strength to firmly support
the machine. When working close to an excavation,
position machine with the propel motors at the rear.
5. Once started, keep bystanders clear, especially
before moving the boom, swinging the upper
structure, or traveling. ALWAYS be alert for
bystanders in or near the operating area.

GENERAL RULES FOR SAFE
OPERATION
1. Read the Operator’s Manual for the excavator
that the grapple is on. Know the control levers and
their functions. Also note ALL safety devices on the
machine and ensure that they are working properly.
2. KNOW the capacity of the excavator and its
attachments. DO NOT overload the machine or
serious injury could result.
3. It is required that a Falling Objects Protection
Structure be installed surrounding the excavator cab
for all material handling applications.
4. DO NOT use attachment for anything except
what it is intended for or warranty will be voided.
5. DO NOT operate a poorly maintained or damaged
grapple. Inspect and lubricate the grapple daily.
6. ALWAYS maintain a safe operating distance
between any material suspended and held by the
attachment and the cab of the machine.
7. NEVER leave a load suspended in the air, pass
it over people, occupied vehicles or buildings or
serious injury could result.
8. ALWAYS keep a watchful eye on exposed parts,
such as the position arm, so as to not damage them
when working in confined spaces.
9. ALWAYS maintain at least 15 feet (5 meters)
between the attachment and any nearby power
lines or serious injury could occur.
10. When leaving the machine for any reason,
ALWAYS lower the grapple to the ground.
11. DO NOT close the attachment on a structure
and reverse the excavator in an attempt to pull
down material.
12. AVOID collision of the boom or attachment,
especially when working with limited visibility or
inside buildings. Know the height and reach of the
processor during operation, travel and swinging
upper structure.
13. AVOID contacting machine with the attachment
or any material held by it.
14. Use machine swing for positioning only. DO
NOT use the attachment as a jack hammer or
wrecking ball.
15. AVOID contact between boom arm or
attachment and overhead obstacles when you
operate, move or haul the machine.
16. The attachment is not a dozer. DO NOT position
the lower (stationary) jaw of the grapple on the
ground and travel forward.
Determine the control for each movement of the
processor before attempting to operate. Practice
the machine movements as described in “Getting
the Feel of the Attachment” on page 3-6.
Operation Section 4 Page 3
GRAPPLES
ATTACHMENT CONTROLS
The Stanley LaBounty grapple replaces the bucket of an excavator and operates with the same controls—no
additional hydraulics are required. The bucket dump control opens the processor and the bucket curl control
closes the attachment (see figures 4-1 and 4-2, below).
BUCKET CURL OUT = GRAPPLE OPEN
BUCKET CURL IN = GRAPPLE CLOSED
FIGURE 4-1
FIGURE 4-2
Page 4 Section 4 Operation
GRAPPLES
GETTING THE FEEL
OF THE ATTACHMENT
Every part of any machine has a slightly different
“operating feel”—an individual machine response to
the movement of the controls. Before starting the
first job with a new machine, it is suggested that
the operator find an open spot on firm, level ground
that is free of obstructions such as trees, buildings
and other equipment—and safely away from other
people. Move the machine to this area and spend
some time just getting to know the operating feel
of the machine and the grapple in order to become
familiar with the control levers and grapple before
beginning work.
The machine is exceedingly powerful. Do not
operate carelessly; there is potential for personal
injury and equipment damage. Be concerned about
safety when preparing to operate the new machine.
Ensure safe operation by inspecting the machine as
stated in “Getting Started Safely,” which includes a
commonsense visual check of the machine at the
beginning of every operation.
Follow a preventive maintenance program; such
a procedure will reduce the possibility of costly
downtime. Read the “Getting Started Safely”
section of this manual and understand it.
THE FEATHERING TECHNIQUE
The fluid nature of hydraulic power requires a
special operating approach to the attachment that
can be described as a smooth, even technique.
The control levers should be moved in a gradual,
deliberate way rather than with jerky, abrupt
movements; jerky operation can cause damage and
early wear to various parts of the machine, and can
also overheat the hydraulic system.
As each control lever is moved forward or
backward from the neutral position, the oil flows
to the cylinder or motor controlling a function. The
component (boom, grapple, etc.) starts to move.
The component moves faster as the control lever
is moved further forward or backward. Holding the
lever in the forward or backward position will hold
that movement at a given rate of speed. To slow
the movement down, gradually move the lever
toward the neutral position. Movement is stopped at
the neutral position. The position is maintained until the
control lever is moved again. See figure 3-6 on page 7.
“Feathering” the controls is a technique that will
increase loading output and make operating the
machine easier. To “feather” when starting any
motion of the machine, move the control slightly
from neutral until it starts to move, then smoothly
move the control to increase motion to desired
speed. Do the same when stopping a motion.

OPERATING TIPS
The mounting pad of a LaBounty Contractor’s Grapple has three pin positions. By using the different
positions, the angle of the lower (stationary) grapple jaw can be adjusted (see figure 4-3). For each type
of job, the lower jaw may be positioned to make it more productive or easier to use.
Use the following guidelines to find the best position for your current job. Some experimentation may be
necessary to learn the advantages of each position.
MOUNTING PAD
FIGURE 4-3
FRONT POSITION
CENTER POSITION
REAR
FRONT
CENTER
CENTER MOUNTING PAD POSITION
REAR POSITION
Use the center position for general use. This will position the lower jaw to provide the best performance
for a great range of uses. Some operators leave the grapple in this position for all applications.
Page 6 Section 4 Operation
GRAPPLES
REAR MOUNTING PAD
POSITION
Using the rear position increases the amount of
grapple opening. This mounting pad position can
make it easier to handle large amounts of light
materials and can also make it easier to empty
the grapple—as when loading a dump truck (see
figure 4-4).
FIGURE 4-4
FRONT MOUNTING PAD
POSITION
NOTICE
DO NOT use tractive effort in this configuration; it will
cause damage to the position arm mounting pad, and/
or excavator stick.
FIGURE 4-5
Using the front position decreases the amount of
grapple opening. This position sometimes works
well when working at ground level because the
lower jaw can be kept parallel to the ground (see
figure 4-5). In this position, use the boom and stick
in a raking motion to load the grapple. This mounting
position can also be useful when placing objects,
such as rip-rap.

MAINTENANCE SAFETY
PROCEDURES
Before attempting any maintenance procedure, read
the entire Safety Manual carefully. If any question
arises regarding a safety or maintenance procedure,
contact your LaBounty dealer.
• Inspect the attachment daily. DO NOT operate a
poorly maintained or damaged attachment or major
structural damage could result.
• 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
the cylinder to hold the attachment in the air. If a
control is moved or hydraulic pressure is otherwise
released, the attachment will drop. DO NOT work
under a machine that is supported solely by a jack.
•DO NOT attempt to alter or change the physical,
mechanical or hydraulic operation of the attachment
during the warranty period without first consulting
Stanley LaBounty as this could invalidate the
Manufacturer’s Warranty.
• NEVER operate the machine if an unsafe
condition exists. Attach a “DO NOT OPERATE” tag
to the machine.
•If more than one person is working on a machine,
each must be familiar with the controls and aware
of what the others are doing. Before working on a
machine, BE SURE TO TAG THE CONTROLS SO
NO ONE ELSE WILL START IT.
•ALWAYS use two people when making checks
with the engine running – the operator at the
controls must be able to see the person doing the
checking.
•Keep hands away from moving parts. NEVER
lubricate or work on a machine while it is moving.
• ALWAYS wear proper safety equipment when

GRAPPLE TINE TIP
REPLACEMENT
LaBounty Grapples are originally equipped with very
hard wear resistant tine tips that will wear after
extended use. When there is approximately one inch
(25.4 mm) left of each tine tip (see figure 5-2) it is
recommended they be replaced to prevent damage
to the grapple frame. Do not allow the tip to wear
down to the tine base material.
1.00
Tine tip replacement kits are available from LaBounty. Consult the parts catalog for your grapple and
contact your LaBounty dealer to order. Use the following procedure to replace a tine tip.
1. Place the grapple in a secure position with the
jaws open and blocked up about 18" high, or preferred working height.
2. Clean all dirt and grease from the tip.
3. Use a straight edge to cut the worn-out edge
square and in line with the other tips, approximately
3/4" (19 mm) from the back edge of the tip profile
(see figure 5-3).
4. Preheat the area to be welded.
5. Position the new tip and tack weld in place. Use a
straight edge to ensure alignment (see figure 5-3).
6. Use a low hydrogen E7018 weld rod or equivalent
to weld the tips in place. Weld the bevels of the
replacement tine tips and grind smooth (see figure
5-3).

NOTICE
Before installing new tips, grind the area to be
welded so it is flat and smooth. Remove any carbon
residue from when the tip was removed.

WEAR PLATE SERVICE KIT
Wear kits are available for grapples that may work in extremely abrasive applications such as rock, concrete,
or brick handling and some scrap applications. Wear kits consist of additional plate steel welded to the front
and back of both grapple halves. Contact your dealer or Stanley LaBounty directly to order, or for more information on availability.

GRAPPLE BUILD UP AND HARDSURFACING
When excessive wear is found on the grapple tines and tips, build up and hardsurfacing are required. For
extremely severe applications, a special wear kit available from LaBounty may provide additional plating of
those areas normally associated with wear in such situations.
The areas that will likely need build up and hardsurfacing are the inner and outer faces of the grapple tines.
The sides of the frames adjacent to these areas may also need this maintenance. The procedure for build up
and hardsurfacing a Contractor’s Grapple is as follows:
1. Clean the areas to be built-up and hardsurfaced to remove any grease, paints, or other foreign materials
that may be harmful to the weld.
2. Preheat the area to 200-300˚F (100-150˚C) and maintain this temperature throughout the build up and hardsurfacing procedure.
3. If build up is to be applied, use a low hydrogen E7018 welding rod or equivalent and weld in single passes
following the grain of the steel (see figure 5-6). Tip build up can be applied cross-grain (see figure 5-7). Peen
each pass.
4. To hardsurface, use an electrode with an abrasive rating of 60-70, hardness of 50-58 Rc and an impact rating of 4.
5. Hardsurfacing should be applied in no more than two layers using a crosshatch pattern at a 45˚ angle to
the vertical. The space between the passes should be from 1" to 2" (25 to 51mm). Peen after each pass.
6. Cover the welded area with a heat blanket. Let it cool slowly before putting the grapple back into service.
