Hydraulic Hammer Operation (If Equipped)
| NOTICE |
|---|
Selection of a hydraulic hammer must be done with extra care. Use of a hydraulic hammer not recommended by AVSpare could result in structural damage to the machine. Consult your AVSpare dealer for hydraulic hammer information. |
Only use the hydraulic hammer to break rocks, concrete, and other hard objects. Before you start hydraulic hammer operation, place the machine on a level, stable surface. If the machine must be placed on a slope or on a rough surface, be careful during operation.
Before you start hydraulic hammer operation, close the front window.
| NOTICE |
|---|
Do not attempt to break rocks or concrete by the force of in/out motion of the hydraulic hammer. Doing this could cause structural damage to the machine. |
Do not allow the hydraulic hammer to continuously operate at one location and for more than 15 seconds. Change the location of the machine and repeat the procedure. Failure to change the location of the machine could cause the hydraulic oil to overheat. Overheated hydraulic oil could cause damage to the accumulator or to the cylinder seals.
Stop hydraulic hammer operation immediately if any of the hydraulic hoses are twisting rapidly. This indicates that the accumulator is punctured. Consult your AVSpare dealer for the necessary repairs.
| NOTICE |
|---|
Do not use the dropping force of the hydraulic hammer to break rocks or other hard objects. This could cause structural damage to the machine. Do not use the sides or back of the hydraulic hammer to move rocks or other hard objects. Doing this could cause damage not only to the hammer but to stick or boom cylinder. Do not operate the hydraulic hammer with any of the cylinders fully retracted or extended. Doing this could cause structural damage to the machine, resulting in reduced machine life. |
Do not use the hydraulic hammer to lift an object.
Do not operate the hydraulic hammer while the stick is vertical to the ground. This could allow the stick cylinder to vibrate excessively.
Operate the attachment control levers carefully in order to keep the hydraulic hammer's chisel from hitting the boom.
Do not operate the hydraulic hammer with the upper structure sideways to the undercarriage. Before you start hydraulic hammer operation, place the upper structure in the recommended position that is shown in working range. Any other operating positions could make the machine unstable. Any other operating positions could place excessive loads on the undercarriage.
Hydraulic Shear Operation (If Equipped)
Illustration 25
 |
Do not operate or work on this attachment unless you have read and understand the instructions and warnings in the Operation And Maintenance Manual for both the attachment and base machine. Failure to follow the instructions or heed the warnings could result in injury or death. Contact any AVSpare dealer for replacement manuals. Proper care is your responsibility. |
 |
| NOTICE |
|---|
Selection of a hydraulic shear must be done with extra care. Use of a hydraulic shear not recommended by AVSpare could result in structural damage to the machine. Consult your AVSpare dealer for hydraulic shear information. |
Be sure that no one is near the attachment in order to prevent injury. Keep the attachment under control at all times in order to prevent injury. When a demolition tool is used, all personnel should maintain a minimum distance of ... 10 m (33 ft).
Close all windows. Make sure that all required guards are in place. Wear all required protective equipment. Follow the instructions in the Operation and Maintenance Manual for the attachment.
|
Serious injury or death could occur from the demolition of pipes, vessels, tanks or other containers that may contain gas, flammable materials or hazardous chemicals. Do not perform any demolition work on these items until all of their contents have been removed. Follow all regulations for the removal and disposal of these materials. |
|
| NOTICE |
|---|
Cutting train or crane rails, engine crankshafts, welded fabrications, bearings, shafts, and other hard metals will increase the wear rate on the cutting edges and the shear. |
| NOTICE |
|---|
Using the demolition tool to level the work site or push over standing structures may damage the machine or the demolition tool. Use appropriate equipment to do site preparation or maintenance operations. |
Position the machine in alignment with the breaking direction in order to break road surfaces. Operate the hydraulic shear while you travel backward.
| NOTICE |
|---|
To avoid structural damage to the machine, do not break road surfaces by placing the cutting edge of the hydraulic shear on the ground and moving the machine. |
In order to peel the road surface with the hydraulic shear, place the cutting edge of the stationary jaw between the road surface and the road bed. Use the bucket cylinder to separate the road surface and the road bed.
| NOTICE |
|---|
Operating the demolition tool with the cylinders fully retracted or fully extended could cause structural damage to the machine. |
| NOTICE |
|---|
Using the machine hydraulic cylinders or the demolition tool rotating device to aid in the breaking or shearing process may damage the machine or the demolition tool rotating device. Use only the arm hydraulic cylinders to perform demolition operations. |
| NOTICE |
|---|
Hitting the demolition tool against the ground or solid object in order to dislodge an obstruction or free the cutting arm may damage the demolition tool or the machine. Use a pry bar or cutting torch to free the cutting arm or dislodge the obstruction. Always check the cutting edge alignment after the jaws are working properly. |
Extending / Retracting Adjustable Track Frames With Hydraulic Adjustable Circuit (If Equipped)
|
Before extending or retracting the track frames, be sure to keep all other people away from the machine. Always use two or more people to do this work. Perform machine movements only after getting signals from a signal man. The automatic engine speed control (AEC) switch must be OFF and the travel speed switch must be in the LOW speed position. Never make a sudden movement of the front implement. When operating the front implement, slowly activate the controls with extra care. |
|
| NOTICE |
|---|
Before starting the adjustment of track frames, clean the contacting areas of the car body and track frames, and their mounting bolts. Prior to installing the bolts, apply Anti-Seize Compound, AVSpare Part No. 9M3710, or equivalent to the underside of the head and to the threads of the bolts. |
