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. · NEVER modify or mount the attachment to a carrier other than the one it was originally designed for. Rotation component failure may result, causing the attachment to fall to the ground.
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). 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.
· NEVER operate the excavator without a proper restraint (seat belt) system in place. Doing so can create loss of control or ejection from the cab.
· 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.

BLEED THE HYDRAULIC CYLINDER
Air must be bled out of the cylinder prior to operation. 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. 1. Start with MDP in the vertical position. 2. Set the excavator at idle speed. 3. 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. 4. Slowly close the jaws until the cylinder rod is extended approximately 1/4 stroke. 5. Retract the cylinder rod all the way. 6. Repeat steps 3 and 4. Extend the rod a quarter inch more each time, until you reach full stroke. 7. 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. 8. Check the base machine hydraulic fluid level and fill if necessary. 9. 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.
OPERATING TIPS
· Start processing smaller materials and work up to larger materials. This will help you learn the limitations of the machine and will allow the machine to warm up properly.
· When handling materials, keep the load as close to the base machine as safely possible. This will provide the greatest machine stability.
· Avoid handling long, heavy materials off center. Excessive weight held out to one side can force the attachment to rotate or “Back-drive”. Back-driving puts increased strain on the rotation system and, if done continually, can lead to rotation component problems. The rotator is for positioning only..
· When processing oversized concrete, make partial bites to start the breakage and then back off before making the next partial bite. This will allow the broken material to fall away between bites.
· Sort your scrap to get the highest capacity from the attachment. · Understand that the attachment does have limits. Sometimes it may be necessary to downsize very large material
by another method before the attachment can process it effectively. · Keep the attachment properly maintained. Jaws with excessive blade gaps or dull teeth are much less effective.
Lack of maintenance can lead to greater problems and potential downtime.

Wear personal protection equipment at all times. This includes eye protection, hard hat, steel toe shoes, leather gloves and hearing protection.
Replacing Swift-Lock Teeth (MDP 20/27/35/50)

Jaw Teeth are very heavy. DO NOT remove a tooth if it is not supported. The tooth may fall and cause injury.
Replacing Weld-In Teeth (MDP 90)

1. Locate flat, hard ground and place the attachment on the ground.
2. Remove the washers on each side of each tooth, using a grinder.
Note: The washers are welded into place. 3. Use a soft metal drift and a mallet to drive out the
tooth pin. 4. Remove the tooth from the receptacle. Note: The retainer ring may fall out when removing the teeth. Do not lose the retainer ring. 5. Insert the retainer ring in its place and insert a new
Swift-Lock tooth. 6. Insert the tooth pin and weld the washers in place. Note: insert the tooth pin so that the pin groove will line up and seat in the retainer ring.

1. Locate flat, hard ground and place the attachment on the ground.
2. Preheat the area around the tooth receptacle to 250° to 300° F.
3. Using carbon-air arc gouging, remove the weld material holding the tooth in place.
4. Remove the tooth. Fill and sand gouges, then clean the tooth receptacle.
5. Fit the new tooth into place. 6. Weld the tooth into place. 7. Cover the weld with a heat blanket and allow it to cool
slowly.

BUILD UP & WEAR PLATES
As the jaws become worn from use, the worn areas will need to be built up to prolong the life of the attachment. Some areas of the jaw have wear plates that protect commonly worn surfaces and reduces the need to build up and hardsurface.

Wear safety equipment when welding. This includes eye protection, hard hat, steel toe shoes, gloves,
hearing protection and respirator. Do all work in a well ventilated area.
CHECKING AND REPLACING WEAR PLATES
Wear bars are welded into the jaw and must be replaced after they have worn down to 1/4 their original thickness.
Using the MDP parts manual, ensure you have ordered the proper wear plate kits.
Installing Wear Bars
1. Preheat the area around the wear bar to 250° to 300° F. 2. Remove the worn wear bar. 3. Fit the new wear bar into the receptacle. Note: Wear bars are pre-cut to length and must be formed to the jaw in the field. 4. Weld the wear bar into place.
MDP Operation & Maintenance Manual | 19

5. Cover the weld with a heat blanket and allow it to cool slowly.

Jaw Teeth Build Up

Wear Plate Locations Figure 23

1. Obtain the proper tooth build up template. Refer to the parts manual for template part numbers. 2. Throughly clean the area to be built up. Grind off any existing hard-surface material. 3. Preheat the area to 200° F (93.3° C) to remove moisture. 4. Preheat the area to be build up to 300° – 400° F (149° – . 204° C) Note: Do not exceed 450° F (232° C). 5. Use the tooth template to determine how much build up is required. 6. Using AWS E7018 welding rod, make hard surface beads, as shown in Figure 24. 7. Relieve stress and remove slag after each pass by peening vigorously with an air operated slag peener. 8. Repeat steps 6 and 7 until the tooth profile matches the build up template. 9. Grind edges square to match the template. 10. Using AWS E7018, place underlayment passes, as shown in Figure 24. 11. Apply a bead of Amalloy 814H rod on top of each of the underlayment beads. Note: Do NOT apply Amalloy 814H to the base metal. 12. Relieve stress after each pass by peening vigorously with an air operated slag peener. 13. Taper the end of each hard-surface bead by grinding. Note: Do NOT undercut the weld. 14. When grinding is complete, peen the area until it is shiny or until the peener cannot dent the weld. Note: About 5-10 minutes. 15. Cover the welded area with a heat blanket and allow to cool slowly.

HYDRAULIC MAINTENANCE
Speed Valve (MDP 35/50/90) The speed valve allows the jaws to shift into high speed when not under a load. Two valve spools control this speed change, the Main Spool Adjustment Screw and the Pilot Valve Adjustment Screw. Testing the Speed Valve Close the jaws and observe the movement. If the speed valve is working properly, the jaw closing speed will increase after 1-2 inches of movement. Adjusting the Speed Valve If the jaw movement doesn’t shift to high speed when CLOSiNg, adjust the pilot valve adjustment screw clockwise until the jaws shift speed.
