Show/hide table

Do not operate the work tool unless you have read and understand the instructions and warnings in the Operation and Maintenance Manual. Failure to follow the instructions or heed the warnings could result in machine or work tool damage, serious injury or death.

Note: Ensure that the work tool is compatible with the host machine. Consult your Verachtert dealer for information on matching the work tool to the host machine.

Note: The work tool can be installed to the stick of the host machine by using a bracket. There are auxiliary lines kits that are available for the hydraulic system. Become familiar with the controls of your machine. Become familiar with the configuration of your machine.

Note: In order to maintain stability of the host machine, work with the tool in line with the tracks of the host machine.

Operate the Jaw

CLOSE - In order to close the jaw, move the control to the CLOSE position.

OPEN - In order to open the jaw, move the control to the OPEN position.

Note: Before you try to rotate the work tool, remove the device that locks the rotator. The VT-30 and VT-40 are equipped with a pin that locks the rotator. The VT-50 and VT-60 are equipped with a plate that locks the rotator. Before you put the work tool into operation, the device that locks the rotator must be removed. Refer to, "Transportation Information" for additional information.

ROTATE RIGHT - In order to rotate the work tool to the right, move the control to the ROTATE RIGHT position.

ROTATE LEFT - In order to rotate the work tool to the left, move the control to the ROTATE LEFT position.

Safe Operating Zone

Illustration 4	g00627757

Zone (D) is the total range of the work tool, when installed on the host machine. Operate the work tool in Zone (C). Zone (A) and Zone (B) are safety zones. Zone (A) is 20° to 25°. Zone (A) is at the bottom of the total range. Zone (B) is 10° to 15°. Zone (B) is at the top of the total range.

Note: Do not operate the work tool in Zone (A) and Zone (B) .

Operating Techniques

Show/hide table

Check the application and install the correct jaws before operating the work tool. Failure to use the work tool with the correct jaws installed could result in structural damage to the work tool, damage to the host machine. Failure to use the work tool with the correct jaws installed could result in serious injury, or death.

Show/hide table

Observe the following precautions when cutting or breaking an object with the multi-processor: Do not use the host machine cylinders Do not rotate the multi-processor Do not use the swing function of the host machine Do not strike the object with the multi-processor Abuse of the multi-processor in this manner can overstress the rotator head bolts. The rotator head bolts can fail, disengaging the multi-processor from the host machine. A falling multi-processor can result in serious injury or death.

The work tool can perform a wide range of operations for demolition.

Hard objects that are standing can be demolished. When using the work tool to demolish hard objects that are standing, position the fixed jaw against the object you want to cut or break. Use the cylinder of the work tool to break or cut the object.

Illustration 5	g01004028

Do not use the host machine cylinders to break the object. Do not use the swing system of the host machine to break the object. You can damage the host machine or the work tool when you use the host machine cylinders or the swing system to break the object. Do not rotate the work tool in order to help break or cut objects.

Illustration 6	g01004029

Do not use the work tool to strike the object.

The tank shear jaws have a piercing tip on the jaw. The piercing tip can be used to make an opening in the object. The opening is large enough for the moveable jaw to penetrate into the object.

Refer to the section"Use of the Jaws" for more information.

Changing the Jaw Sets

Show/hide table

The jaw set change procedure must be performed on a surface that is solid and level. Severe injury or death from falling objects or from crushing could occur.

Note: Clean the work tool before the jaw set change.
