GENERAL

If the attachment is not functioning properly, shut down the machine, follow proper Lock-out / Tag-out procedures and follow proper repair procedures.
Remove and replace any damaged or worn parts with parts recommended by LaBounty. Use of parts that are not factory approved may cause damage or unnecessary downtime and may void the warranty.
NEVER operate equipment without the original safety guards in place.
DO NOT process material with the attachment over the operator’s cab. Doing so will result in severe personal injury or death from falling debris.
DO NOT attempt to process brittle materials, such as axles and railroad rail. DO NOT process any material in a position that may propel it toward the operator, other workers, buildings or equipment.
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 (23 meters).
NEVER approach power lines with any part of the machine. Keep clear at a minimum of 15 feet (5 meters).
DO NOT close the attachment on a structure and reverse the excavator in an attempt to pull down material.
Use of this tool on certain materials could generate dust potentially containing a variety of hazardous substances, such as, asbestos, silica or lead. Inhalation of dust containing these, or other hazardous substances could result in serious injury, cancer or death. Protect yourself and those around you. Research and understand the materials you are processing. Follow safety procedures and comply with all applicable national, state or provisional health and safety regulations relating to them. If appropriate, arrange for the safe disposal of the materials by a qualified person.
Disassembly of any pin-connected attachment can be hazardous. NEVER remove any pin unless the attachment is on the ground and blocked up. 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. Always keep people clear when removing or installing pins.
Do not operate this, or any other equipment, under the influence of drugs or alcohol.
DO NOT modify LaBounty equipment without factory authorization. This equipment is designed to do a specific job and alterations could result in injury.
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. If a control is moved or hydraulic pressure is otherwise released, the attachment may drop. DO NOT work under a machine that is supported only by a jack.
DO NOT weld on any structural member unless specifically authorized by LaBounty. Unauthorized welding will void the warranty, may cause structural failure and could result in personal injury.
Keep clear of potential pinch points, including the moving upper jaw, cylinder connections, bucket linkages and other moving parts.
Before operating the attachment, read and observe all safety instructions in the Operation & Maintenance manual. If you are unfamiliar with any operation or maintenance procedure, seek instruction before proceeding.
Inspect the attachment daily. Do not operate a poorly maintained or damaged attachment.
Never operate a machine if an unsafe condition exists. Attach a “Do Not Operate” tag to the machine.

BASE MACHINE

Ensure that the cab is equipped with the proper safety guards for LaBounty applications. The cab MUST be equipped with an approved Falling Object Protection Structure (FOPS) and cab guarding. 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 and cab guarding. Lack of proper FOPS and guards may result in injury or death.
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. Lifting incorrectly can cause severe injury or machine damage. Use the recommended excavator counterweight. Use short slings and lift the load only as high as necessary.
DO NOT allow riders on the machine. Riders are subject to serious injuries, such as being struck by foreign objects or being thrown off the machine. Riders also distract and obstruct the operator, resulting in the machine being operated in an unsafe manner. NEVER use the attachment as a work platform or personnel carrier.
Check ground conditions before operating. Avoid unstable or slippery areas and position the base machine on firm, level ground. If level ground is not possible, position the base machine to use the attachment to the front or back of the carrier. Avoid working over the side of the base machine.

HYDRAULIC

Hydraulic oil becomes hot during operation. DO NOT come in contact with hot hydraulic oil as it could cause severe burns. Wear adequate protective clothing and safety equipment.
DO NOT tamper with hydraulic lines or components while they are pressurized. Escaping fluid under pressure can penetrate the skin, causing serious injury. 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.

PPE
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. Safety equipment includes eye protection, hard hat, steel toe shoes, gloves, hearing protection and respirator.

General Rules For Safe Operation

KNOW the capacity of the excavator and it’s attachments. DO NOT overload or serious injury could result. The attachment may have altered the machine’s lift capabilities.
This attachment is for processing materials. DO NOT use for unapproved purposes.
DO NOT continuously process oversized materials by forcing them into the jaw. This will shorten the life of the attachment.
If attachment stalls, scale back the amount of material being processed at one time. Overloading can cause overheating or damage to the hydraulic system.
Cycle the cylinder completely when processing. Fully cycling will allow hydraulic fluid to circulate and prevents overheating.
Maintain a safe distance.
NEVER leave the attachment suspended or pass it over people, occupied vehicles or buildings.
When working in confined spaces, keep watch on exposed parts, such as cylinder rods and hoses, to avoid damage.
Maintain at least 50 feet (15 meters) between the attachment and any nearby power lines.
ALWAYS lower the attachment to the ground and turn the base machine off when leaving the machine unattended.
DO NOT close the jaws on a structure and reverse the excavator in an attempt to pull down material. This is dangerous and will damage the excavator and the attachment.
Avoid collision of the boom or jaws, especially when working with limited visibility or inside buildings. Know the height and reach of the attachment during operation, transport and when swinging the excavator.
DO NOT alter factory preset hydraulics. This may void the warranty.
DO NOT shear high tensile steel, such as railroad rail, spring steel, axles and some types of wire. Jaw damage will result. This type of material breaks when processed and can become a projectile which could cause injury or death. MHP 150 – 550 Mobile Hydraulic Pulverizer Operation & Maintenance Manual | 11
Use attachment rotation for positioning only. Do not use if for bending, breaking or prying.
DO NOT use attachment as a jack hammer or wrecking ball.
DO NOT attempt to shear material stuck through the lower jaw.
Before shearing thin material, ensure the blades are sharp and properly adjusted. Thin material may jam the blades.
DO NOT apply excavator force at the ends of the upper shear in an attempt to un-jam the jaws or cut material that is too large for the shear.

BLEED THE ATTACHMENT HYDRAULIC CIRCUIT
Air must be bled out of the hydraulic circuit prior to operation. Air in the hydraulic 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.

Start with the attachment in the vertical position.
Set the excavator at idle speed.
Slowly open the jaws until a noticeable change in tone of the excavator is heard, indicating a full cylinder. Release the controls and do not continue to apply full operating pressure to the cylinder.
Slowly close the jaws until the cylinder rod is extended approximately 1/4 stroke.
Open the jaws to retract the cylinder all the way.
Repeat steps 3 and 4. Extend the cylinder a quarter stroke more each time, until you reach full stroke.
Slowly cycle back and forth, at least five times, to full stroke. Be careful not to apply full operating pressure to the cylinder at this time.
Check the base machine hydraulic fluid level and fill if necessary.
Slowly extend and retract the excavator cylinder to it’s limits. Check for interference between the attachment and the excavator boom or stick. Check the hydraulic lines that connect to the attachment. Ensure they are not rubbing or becoming damaged in any way. Contact your dealer immediately if interference occurs.
