Safety

W A R N I N G

Working with unfamiliar equipment can lead to careless injuries. Read and understand this manual and the manual for your vehicle before assembling, installing, operating, maintaining, servicing, removing, or moving this Postmaster/Slab Blaster. If there is anything in this manual you do not understand, contact your dealer or Danuser Machine Company, Inc. The safe use of this attachment is strictly up to you, the operator. If this attachment is used, loaned, or rented by any other person, it is the owner's responsibility to make certain that the operator prior to operating:

• Reads and understands the Operator's Manuals

• Is instructed in safe and proper use

• The Postmaster/Slab Blaster is designed to be operated from the vehicle seat. Keep bystanders away from the work area. Do not operate with another person in contact with any part of the Postmaster/ Slab Blaster.

• All operators of this attachment must read and understand this entire manual, paying particular attention to safety messages and operation instructions, prior to assembling, installing, operating, maintaining, servicing, removing, or moving the Postmaster/Slab Blaster.

• Please remember it is also important that you read, understand, and follow safety signs on the attachment. Clean or replace all safety signs if they cannot be clearly read and understood. They are there for your safety as well as the safety of others. Danuser Machine Company, Inc. will furnish new safety signs upon request at no charge.

• All things with moving parts are potentially hazardous. There is no substitute for a cautious, safe minded operator who recognizes potential hazards and follows reasonable safety practices.

• Personal protection equipment including hard hat, safety glasses, safety shoes, gloves, and ear plugs are recommended during assembly, installation, operation, maintenance, service, removal, or movement of the attachment.

• When the use of hand tools is required to perform any part of assembly, installation, operation, maintenance, or service of the attachment, be sure the tools used are designed and recommended by the tool manufacturer for that specific task.

• Never check pressurized system for leaks with your bare hand. Wear proper hand and eye protection and use wood or cardboard when searching for suspected leaks. Oil escaping from pinhole leaks under pressure can penetrate skin and create a serious medical emergency. If any fluid is injected into the skin, gangrene, blood poisoning, even death may result. Obtain medical attention immediately.

• Always use two people to handle heavy, unwieldy components during assembly, installation, maintenance, service, removal, or movement of the Postmaster/Slab Blaster.

• Never place any part of your body where it would be in danger if movement should occur during assembly, installation, operation, maintenance, service, removal, or movement of the Postmaster/Slab Blaster.

Hydraulic

Filtration Requirements:

Requirements

• A filter of, at least, 25 micron filtration is required. A filter capable of 10 micron filtration is preferred. The majority of paper type filters are 25 microns or better.

NOTE

• A low pressure type filter can be installed in the return line from the control valves to the sump. A low pressure type filter can, also, be installed in the sump or pump intake line, but must be sized large enough to avoid starving the pump.

• A high pressure type filter can be used between the pump and the control valves.

• If the source of the hydraulic power does not have a filter, it will be necessary to install one at some point in the system so, at least, part of the hydraulic oil is being filtered whenever the system is operating. After a filter is installed and before attaching the Postmaster/Slab Blaster, the entire hydraulic system should be drained, filled with new oil, and operated for 30 minutes or until the system is warm. During this run time, operate all valves, cylinders, and hydraulic motors on the attachment.

Pressure and Flow Requirements:

• The Postmaster/Slab Blaster is designed to operate at 12 GPM and 2000 PSI.

The life of the hydraulic motor is almost entirely dependent upon cleanliness of the oil. Instructions in your vehicle operator’s manual regarding filter and oil changes should be carefully followed. Even small amounts of dirt in the hydraulic oil can cause premature motor failure that is not covered by warranty.

Valve Requirements:

• The hydraulic system used to power the Postmaster/Slab Blaster should be equipped with a four-way valve large enough to carry full pump outlet without restricting flow and causing oil heating.

• The four-way valve requires a relief valve which will open and relieve extreme pressures between the Postmaster/Slab Blaster and control valve, even when the control valve is in a neutral position. This feature can be obtained by connecting two external relief valves between the main lines running from the control valve to the Postmaster/ Slab Blaster in such a way that high pressure in either line will be relieved to the other line.

Hydraulic Fluid Selection Requirements:

• Premium grade petroleum based fluids will provide the best performance.

• Fluids that contain anti-wear agents, rust inhibitors, anti-foaming agents, and oxidation inhibitors are recommended.

• The viscosity of the fluid should never fall below 70 SUS (13 cST). The best viscosity range of the Postmaster/Slab Blaster is 100-200 SUS (20-43 cST).

Assembly &

Installation

W A R N I N G

Personal protection equipment including hard hat, safety glasses, safety shoes, gloves, and ear plugs are recommended during assembly, installation, operation, maintenance, service, removal, or movement of the attachment.

Prepare the Vehicle

Read and understand the manual for your vehicle before assembling or installing the Postmaster/Slab Blaster. The vehicle must be equipped with a universal quick attach hitch and auxiliary hydraulics. The use of the Postmaster/Slab Blaster may require the addition of counterweights to ensure the attachment does not exceed the rated capacity of your vehicle.

D A N G E R

Do not exceed the vehicle's rated operating load. If necessary, use sufficient counterweights.

Add Additional Weight

Adding additional weight, up to 700 lbs. total hammer weight, is recommended on both the Postmaster and Slab Blaster, except when using a T-post adapter. Add weight in a variety of ways: logging chain, metal punch slugs, lead tire weights, etc. Do not use concrete or sand.

STEP 1: If your unit was shipped in the upright position, remove the lag bolt securing the Postmaster/Slab Blaster to the pallet.

STEP 2: Remove the metal bands from around the mounting plate and pallet.

STEP 3: If you have received a Postmaster with Grapple, remove the Grapple from the Postmaster. The Grapple will be installed later.

NOTE

If you have purchased a Postmaster with Grapple, it is recommended you use your Postmaster without the Grapple a few times before installing the Grapple. The Grapple installation instructions are located in the Operation section of this manual following the Postmaster operation instructions.

W A R N I N G

C A U T I O N

Because of the weight of some components, and because some components are difficult to balance, two people are required for safe assembly and installation of this equipment.

STEP 4: Install the Postmaster/Slab Blaster by following your vehicle operator’s manual for installing an attachment. After making sure the attachment is securely latched to the vehicle, remove the shipping pallet.

W A R N I N G

Make sure the Postmaster/Slab Blaster is securely latched to the vehicle. Failure to do so could result in separation of the attachment from the vehicle.

STEP 5: Remove the hydraulic hoses from the quick attach plate hose holder, and use the quick couplers to connect the hydraulic hoses to the vehicle's auxiliary hydraulics.

W A R N I N G

Remember hydraulic systems are under pressure whenever the engine is running and may hold pressure after shutdown. Before connecting or disconnecting hydraulic hoses, be sure to relieve all pressure by cycling all hydraulic controls after shutdown.

C A U T I O N

Do not route the hydraulic hoses through the quick attach plate hose holder at this time. Damage to the hydraulic hoses will occur.

STEP 6: Remove the transit bolt from the top left of the hammer rails.

Assembly &

Installation

(continued)

C A U T I O N

Always reinstall the transit bolt before transporting or shipping the Postmaster/Slab Blaster. This bolt prevents the hammer from sliding during transport or shipping.

STEP 7: Ensure the safety catch is in place. The safety catch prevents the hammer from sliding out of the Postmaster/Slab Blaster.

W A R N I N G

Do not tilt or operate the Postmaster/Slab Blaster without the safety catch in place. The hammer could slide out of the Postmaster/Slab Blaster and cause serious injury or death.

Transit Bolt

Safety Catch

STEP 8: Raise the Postmaster/Slab Blaster in the air, and tilt it forward 90°. Watch for any obstructions or pinching of hydraulic hoses.

STEP 9: Shut off the vehicle engine.

STEP 10: Grease the exposed hammer rails.

STEP 11: Again ensure the safety catch is in place, and pull the hammer out towards you until it hits the safety catch. Grease the rest of the hammer rails, and oil the chain drive.

STEP 12: Set the hydraulic flow control at 3.

Flow Control

C A U T I O N

Do not operate the Postmaster/Slab Blaster without first setting the flow control. Serious damage to the drive assembly may occur.

Assembly &

Installation

STEP 13: Start the vehicle. Running at full throttle, engage the auxiliary hydraulics. Note the direction of the chain rotation (visible from the operator’s seat). The chain should be rotating from the bottom to the top. If it is not, reverse the hydraulic hoses.

(continued)

Vehicle

NOTE

W A R N I N G

Keep hands and loose clothing clear of the chain drive assembly. Severe personal injury could occur.

Pick-Up Link

Hammer

If the Grapple is installed and the chain is not rotating at all, reverse the hydraulic hoses.

W A R N I N G

STEP 14: Check the hydraulic system for leaks.

W A R N I N G

Never check pressurized system for leaks with your bare hand. Wear proper hand and eye protection and use wood or cardboard when searching for suspected leaks. Oil escaping from pinhole leaks under pressure can penetrate skin and create a serious medical emergency. If any fluid is injected into the skin, gangrene, blood poisoning, even death may result. Obtain medical attention immediately.

STEP 15: After the correct chain rotation has been achieved, count the number of rotations of the pick-up link per minute.

STEP 16: The number of rotations equals the number of hammer strikes per minute. If you want to increase the speed, then increase the flow control setting by 1 increment at a time until you reach the desired number of rotations per minute. DO NOT exceed the maximum of 50 rotations per minute.

W A R N I N G

Exceeding 50 rotations per minute will cycle the chain faster than the hammer drops, making the chain come into contact with the hammer as it is still falling. This will cause severe damage to the drive assembly.

Assembly &

Installation

STEP 17: After setting the flow control, turn off the auxiliary hydraulics. Slide the hammer back into the Postmaster/Slab Blaster.

STEP 18: Slowly tilt the Postmaster/Slab Blaster back to a vertical position.

(continued)

Operation

Postmaster

D A N G E R

The Postmaster is designed to be operated from the vehicle seat. Keep bystanders away from the work area. Do not operate with another person in contact with any part of the Postmaster.

STEP 19: Shut off the vehicle, and disconnect the hydraulic hoses. Route the hydraulic hoses through the quick attach plate hose holder, and reconnect the hydraulic hoses to the vehicle auxiliary hydraulics.

D A N G E R

Before you operate the attachment, check over pins and connections to be sure they all are securely in place. Make sure the Postmaster/Slab Blaster is securely latched to the vehicle.

D A N G E R

Consult local utility companies to make certain there are no buried gas lines, electrical cables, etc., in the work area before beginning operation. Do not drive posts near underground utility lines.

C A U T I O N

D A N G E R

Stay away from power lines when transporting, raising, or operating the attachment.

Do not operate the Postmaster/Slab Blaster with the transit bolt installed.

If you have purchased a Postmaster with Grapple, we recommend you use your Postmaster without the Grapple a few times before installing the Grapple.

STEP 1: Without the Grapple, the Postmaster requires a second person to position the post. This person will set the post at the desired location and grasp the post securely, making sure his hands are at least 30 inches from the top of the post.

D A N G E R

When using a second person, do not turn on the auxiliary hydraulics until the second person is clear from the work area.

STEP 2: After the post is in position, move the vehicle with the arms raised and position the Postmaster directly over the top of the post.

STEP 3: Lower the Postmaster onto the top of the post, ensuring the post is inside of the positioning collar. Continue lowering until the collar and head assembly have moved up approximately 2 inches. Gauge this measurement by watching the post guide on the back of the attachment, visible from the vehicle operator’s seat.

D A N G E R

After the post is in position, the second person must move away from the Postmaster and vehicle.

Operation

(continued)

STEP 4: After the second person has cleared the area, continue lowering the Postmaster onto the post approximately 24 inches. Gauge this measurement by noting when

STEP 5: Move the vehicle slowly left, right, forward, or backward as needed until the post appears vertical to the ground.

STEP 6: The Postmaster can now be activated by turning the auxiliary hydraulics to the forward position. Drive the post into the ground until the post guide is approximately 6 inches above the rubber cushion. If needed, shut off the auxiliary hydraulics and reposition the vehicle to ensure the post is driven into the ground straight.

C A U T I O N

Failure to lower the Postmaster as the post guide nears the rubber cushion will result in the hammer bottoming out. Although occasional bottoming out of the hammer will give the operator a jolt, it will not (under normal load conditions) damage the Postmaster. However, repeated bottoming out of the hammer will cause structural damage and excessive wear to the Postmaster and vehicle lift arms.

Assembly &

Installation

STEP 7: Repeat STEPS 4 and 6 until the post has been driven to the desired depth.

STEP 8: Shut off the auxiliary hydraulics, raise the Postmaster until the post is cleared, and move to the next post.

Once you have become comfortable with the operation of the Postmaster and are driving posts in straight, you are ready to install your Grapple.

STEP 1: Lower the Postmaster to the ground, and shut off the vehicle.

W A R N I N G

Assembly &

Installation

(continued)

STEP 2: Set the Grapple down in front of the Postmaster, aligning the square tubes of the Grapple with the square tubes of the Postmaster (one on either side of the chain guard and drive assembly).

STEP 3: Remove the hitch pins from the Grapple mounting tubes.

STEP 4: Slide the square tubes of the Grapple into the tubes of the Postmaster. Align the mounting holes, and insert the provided hitch pins and hair pins.

W A R N I N G

C A U T I O N

Because of the weight of

some components, and because some

components are difficult

to balance, two people are required for safe

assembly and installation

of this equipment.

STEP 5: Route the hydraulic hoses for the Grapple through the quick attach plate hose holder, and connect the couplers to the corresponding couplers located directly

 belowtheowcontrol.

STEP 6: The Grapple hydraulic system has been shipped dry and will require the auxiliary

erratic until all the air is out of the hydraulic system.)

STEP 7: With the vehicle running at slow idle, turn the auxiliary hydraulics to the forward position for a few seconds at a time until the Grapple arms raise. (Be cautious when the Grapple is raised and the jaws are completely open, as the hammer will rise.)

C A U T I O N

Repeated bottoming out of the hammer will cause severe damage to the attachment and will void all warranties.

STEP 8: Reverse the auxiliary hydraulics until the jaws close.

STEP 9: Repeat STEPS 7 and 8 until Grapple operation is smooth.

STEP 10: Once you have accomplished smooth operation and the Grapple jaws are closed, return the auxiliary hydraulics to the forward position until the hammer starts to raise. This will raise and open the Grapple jaws.

Operation

With Grapple

D A N G E R

The Postmaster is designed to be operated from the vehicle seat. Keep bystanders away from the work area. Do not operate with another person in contact with any part of the Postmaster.

D A N G E R

Stay away from power lines when transporting, raising, or operating the attachment.

D A N G E R

Before you operate the attachment, check over pins and connections to be sure they all are securely in place. Make sure the Postmaster/Slab Blaster is securely latched to the vehicle.

D A N G E R

Consult local utility companies to make certain there are no buried gas lines, electrical cables, etc., in the work area before beginning operation. Do not drive posts near underground utility lines.

C A U T I O N

Do not operate the Postmaster/Slab Blaster with the transit bolt installed.

Operation

(continued)

Picking up a post from the ground may require a few tries to get it perfect. We recommend attaching a 24 inch length of deck chain to the hook provided next to the bottom of the drive assembly. This will help the operator align the Grapple jaws with the head of the post, ensuring a perfect pick-up of the post every time.

NOTE

STEP 1: Set the post(s) on the ground with the head(s) of the post(s) facing the vehicle.

STEP 2: Raise the Postmaster approximately 2 feet off the ground, making sure the Grapple arms are in the up position and the jaws are open.

STEP 3: Drive the vehicle forward and position the Postmaster over the head of the post. Align the end of the guide chain approximately 1 to 2 inches to the right of the head of the post.

NOTE

STEP 4: After the vehicle is in position, lower the lift arms until the Postmaster is resting lightly on the post, allowing for the grapple to center the post.

STEP 5: Turn the auxiliary hydraulics to the reverse position until the jaws close on the post.

STEP 6: Lift the Postmaster 4 to 6 inches off the ground. Turn the auxiliary hydraulics to the reverse position until the post is securely held by the Grapple.

This guide chain may need to be adjusted up or down in length to compensate for the arc of the vehicle’s lift arms.

You do not need to center the jaws over the post since the grapple is self aligning.

STEP 7: Raise the arms of the vehicle until the post has swung down and is clear of the ground. This should set the head of the post into the positioning collar. If the post is jammed against the front or back of the positioning collar, DO NOT release the jaws. Back up the vehicle while lowering the post to the ground. Once the post is on the ground, open the jaws.

W A R N I N G

Opening the jaws of the Grapple when the post is not in the positioning collar could cause the post to fall back toward the vehicle. Serious injury to the operator could occur.

NOTE

STEP 8: When the post has been properly positioned in the positioning collar, move the vehicle to the desired location, and lower the lift arms until the tip of the post is touching the ground.

If the post was jammed on the back of the positioning collar (toward the vehicle), shorten the guide chain one link at a time. Repeat STEPS 3 - 7 until the post is positioned in the collar. If the fence post was jammed on the front of the positioning collar, lengthen the guide chain one link at a time. Repeat STEPS 3 7 until the post is positioned in the collar.

STEP 9: Brieyturntheauxiliaryhydraulicstotheforwardpositionjustenoughtorelease the hydraulic pressure. You do not want the jaws to open at this time. Releasing the hydraulic pressure should loosen the jaws enough that the post will slide through but still maintain the spring tension that is holding the post in position.

STEP 10: Align the post by moving the vehicle and using the guide chain as a plum line.

Operation

STEP 11: Lower the Postmaster onto the post approximately 24 inches. Reposition the vehicle using the guide chain as a plum line.

(continued)

STEP 12: Turn on the auxiliary hydraulics in the forward position. This will open the jaws, swing the Grapple out of the way, and start the hammer.

The Postmaster is designed to be operated from the vehicle seat. Keep bystanders away from the work area. Do not operate with another person in contact with any part of the Postmaster.

D A N G E R

Stay away from power lines when transporting, raising, or operating the attachment.

Consult local utility companies to make certain there are no buried gas lines, electrical cables, etc., in the work area before beginning operation. Do not drive posts near underground utility lines.

C A U T I O N

Do not operate the Postmaster/Slab Blaster with the transit bolt installed.

The Slab Blaster operates basically the same as the Postmaster with the exception that the Slab Blaster has a one-piece hammer. It does not have a separate head and hammer assembly. The Slab Blaster hammer has approximately 9 inches of wearable, hardened steel hammer point.

STEP 1: Move the vehicle into position with the arms raised and the Slab Blaster positioned directly over the concrete you wish to break up.

STEP 2: Lower the Slab Blaster until it is approximately 2 to 3 inches off of the concrete. This means the hammer will be slightly pushed up into the hammer rails.

C A U T I O N

Failure to lower the Slab Blaster 2 to 3 inches from the ground will result in the hammer hitting the rubber cushion. Although occasional bottoming out of the hammer will give the operator a jolt, it will not (under normal load conditions) damage the Slab Blaster. However, repeated bottoming out of the hammer will cause structural damage and excessive wear to the Slab Blaster and vehicle lift arms.

Operation

STEP 3: The Slab Blaster can now be activated by turning the auxiliary hydraulics to the forward position.

Removal &

Storage

NOTE

Before storage, the Postmaster/Slab Blaster should be thoroughly cleaned, washing off all dirt and grime. If you have a Grapple or Tilt, coat the exposed portions of the cylinder rod

withgrease.Lubricatethedrivechain,chaincoupler,andallgreasettings.Makesurethe

hydraulic system is properly sealed against contaminates entering the unit. Always store the Postmaster/Slab Blaster in a dry, covered location.

STEP 1: LowerthePostmaster/SlabBlasterontoaat,levelsurface.

The Slab Blaster will break up approximately ten square feet of concrete per minute. The thickness (up to 9 inches) and the toughness of the concrete will affect your speed.

D A N G E R

Never allow anyone under the attachment at any time.

STEP 2: Shut off the vehicle engine, lower the arms, relieve all hydraulic pressure (by activating the vehicle controls), and remove the vehicle key before leaving the vehicle seat.

W A R N I N G

Before disconnecting hydraulic lines or fittings be sure to relieve all pressure by cycling all hydraulic controls after shutdown. Remember hydraulic systems are under pressure whenever the engine is running and may hold pressure after shutdown.

STEP 3: Disconnect the hydraulic hoses from the vehicle's auxiliary hydraulics.

NOTE

STEP 4: Follow your vehicle operator's manual for removing an attachment.

Connect the quick couplers together to prevent contaminants from entering the Postmaster/Slab Blaster hydraulic system.

Maintenance

DAILY

CHECK FOR CLEAN HYDRAULIC OIL

The majority of all hydraulic component failures are caused by contamination of the hydraulic oil. At all times, keep dirt and other contaminates from entering the hydraulic system during connecting and disconnecting the hydraulic system. Always use dust caps and plugs on all quick disconnects when not in use.

CHECK ALL HYDRAULIC HOSE ASSEMBLIES

Check for cracked or brittle hoses. Replace hoses immediately if cracked or brittle. Replacement of hoses before failure will prevent loss of hydraulic oil, hydraulic oil contamination, and component damage caused by cavitation.

CHECK ATTACHMENT AND ALL ACCESSORIES

Check all bolts and fasteners for tightness. Visually inspect the attachment for damage. Visually check the drive chain for alignment. Check the flow control mounting bolts for damage or breakage, and replace if necessary. (Repeated bottoming out of the attachment is the only cause of damage to the mounting bolts. If mounting bolts are damaged or breaking, check the complete attachment for structural damage and review operating procedures.)

CHECK RUBBER CUSHION

Visually check the rubber cushion for damage and wear. (Repeated bottoming out of the unit is the only cause of wear or damage to the rubber cushion. If the rubber cushion is showing wear or damage, check the complete attachment for structural damage and review operating procedures.)

EVERY 40 HOURS

GREASE ZERKS

Grease the zerks on each of the 4 bearings. Grease the zerks on both ends of the Grapple's pivot linkage.

LUBRICATE ATTACHMENT

Lubricate the hammer rails. Lubricate the drive chain and chain coupling with a high quality commercial chain lubricant.

CHECK ATTACHMENT AND ACCESSORIES

Visually inspect the nylon guide plate for wear. Replace the nylon guide plate if the drive chain is hitting the flathead socket capscrews. Check the bolts on the Postmaster upper head assembly for tightness.

Service

D A N G E R

Never attempt repairs or adjustments while the equipment is in operation.

W A R N I N G

C A U T I O N

Because of the weight of

some components, and because some

components are difficult

to balance, two people are required for safe

assembly and installation

of this equipment.

REPLACING THE DRIVE CHAIN

STEP 1: Remove the safety catch pin from the top of the frame. Insert a hook into the chain links welded to the top of the hammer, and lift out the hammer with a hoist, forklift, or another vehicle. Lay the hammer on the ground.

STEP 2: Disconnect the hydraulic hoses, and remove the Postmaster/Slab Blaster from the vehicle.

STEP 3: Carefully lay down the Postmaster/Slab Blaster on its back.

STEP 4: Remove the front cover.

STEP 5: Remove the chain. (The drive chain has been welded together and must be cut off.)

STEP 6: Loosen the bolts on the bearings, allowing the sprockets to slide closer together for reassembly.

NOTE

STEP 7: Check the alignment of the sprockets by measuring the distance from each side of the sprocket to the frame on the upper and lower sprocket. Then place a straight edge on the side of the sprockets from the upper sprocket to the lower sprocket to ensure straight alignment.

Check sprockets and nylon guide plate for wear and replace if necessary.

CHANGING THE POSTMASTER UPPER HEAD ASSEMBLY

OR CHANGING THE COLLAR

STEP 2: Disconnect the hydraulic hoses from the vehicle auxiliary hydraulics, remove them from the quick attach plate hose holder, and reconnect the hydraulic hoses to the vehicle.

C A U T I O N

Do not tilt the Postmaster with the hydraulic hoses routed through the quick attach plate hose holder. Damage to the hydraulic hoses will occur.

STEP 3: Raise the Postmaster in the air, and tilt it forward 90°. Watch for any obstructions or pinching of hydraulic hoses.

STEP 4: Shut off the vehicle engine.

Service

(continued)

STEP 5: With the Postmaster in a horizontal position, remove the head assembly.

STEP 6: If you are changing the collar only, then remove the bolts securing the collar to the upper head assembly, and install the desired collar using the existing bolts. Reinstall the head assembly with the collar into the Postmaster. If you are changing the upper head assembly only, then remove the bolts securing the collar to the existing upper head assembly, and install the collar onto the new head assembly. Install the new assembly into the Postmaster. If you are changing the complete upper head assembly with collar, then remove the existing head assembly, and install the new assembly into the Postmaster.

C A U T I O N

The 8 inch collar assembly must be installed in the Postmaster with the flat portion of the collar towards the drive chain. Failure to install the collar correctly will cause the pick-up link to catch on the collar and lift the collar off the post. When this happens, the post will not be held securely and may cause damage to the drive chain and collar.

NOTE

STEP 7: After the upper head assembly has be reinstalled, start the vehicle, and slowly tilt the Postmaster back to a vertical position.

STEP 8: Shut off the vehicle, and disconnect the hydraulic hoses. Route the hydraulic hoses through the quick attach plate hose holder, and reconnect the hydraulic hoses to the vehicle auxiliary hydraulics.

STEP 9: Lift the Postmaster hammer, and reinstall it in the Postmaster.

STEP 10: Ensure the safety catch is in place. The safety catch prevents the hammer from sliding out of the Postmaster.

Frequent changing of post head collars could result in the lock nut (securing the collar to the upper head assembly) to lose its effectiveness. Check for tightness regularly and replace if necessary.

W A R N I N G

Do not tilt or operate the Postmaster/Slab Blaster without the safety catch in place. The hammer could slide out of the Postmaster/Slab Blaster and cause serious injury or death.
