# Operation

# Ergonomic Guidelines

Consider your workstation as you read through this list of general ergonomic guidelines to identify areas for improvement in posture, component placement, or work environment.

- Take frequent breaks and change work positions frequently.

- Adapt the workstation area to your needs and the work task.

  - Adjust for a convenient reach range by determining where parts and tools need to be located to avoid static load.

  - Use workstation equipment such as tables and chairs appropriate for the work task.

- Avoid work positions above shoulder level or with static holding during assembly operations.

  - When working above shoulder level, reduce the load on the static muscles by lowering the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.

  - Take frequent breaks.

  - Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.

- Adjust for a convenient field of vision that requires minimal eye and head movements.

- Use appropriate lighting for the work task.

- Select the appropriate tool for the work task.

- In noisy environments, use ear protection equipment.

- Use high-quality inserted tools and consumables to minimize exposure to excessive levels of vibration.

# Operating Instructions

# How the Flange Spreading Wedges Work

When spreading a flange joint, it is recommended to use two wedges set 180 degrees apart on the joint. This will ensure that the flange joint can be opened evenly.

1. The flange spreading wedge is placed between the flanges to be spread with the full step area fully inserted as far as the heel of the chosen step.

2. The flange is spread using either mechanical ACMS08T or ACHS14T.

3. Once the joint has been opened to the desired distance, the safety blocks are inserted into the flange joint and the pressure released gradually back onto them.

4. The wedges can then be re-inserted using the next step and the flange joint can be opened further.

5. Repeat this procedure until the flange joint has been opened wide enough to carry out the remedial work (for example, gasket replacement).

# ACHS14T Installation and Operation

WARNING

Reduce Lateral Flange Movement

- Before attaching the tool, make sure that at least two flange bolts remain in place 180 degrees apart with nuts loosened sufficiently enough for flange work to be carried out. These bolts will reduce the lateral flange movement during flange spreading.

1. Determine the flange joint access gap – a minimum access gap of 6 mm (0.24") is required.

2. Before installing the wedge, the hose should be connected to the respective couplings on the pump and cylinder.

3. Insert the wedge into the joint until the heel of the step is in contact with the outer surface of the joint. Make sure that the full step is used and that the jaw is positioned centrally. Inserting the wedge incorrectly may result in tool breakage and render the warranty void.

4. It is strongly recommended that two ACHS14T wedges be used on the flange joint positioned 180 degrees apart. Prime each pump individually to make sure that the flange joint opens evenly.

5. When the joint has been opened to the desired spreading distance, or the maximum spreading distance on the current step is reached, the safety block should be inserted into the joint and the pressure released back onto it.

6. The wedge can then be re-inserted on its next step and the joint opened further.

7. Once the joint has been spread and all work completed, the wedges should be removed by reversing steps 4–6. Release the wedges by turning the release valve on the pump anti-clockwise. Make sure that the wedges are released evenly until completely closed. Care should be taken not to drop any of the component parts when removing them from the flange joint. This action will prevent injuries to either the operator’s lower limbs, or to passers-by.

# ACMS08T Installation and Operation

WARNING

Reduce Lateral Flange Movement

- Before attaching the tool, make sure that at least two flange bolts remain in place 180 degrees apart with nuts loosened sufficiently enough for flange work to be carried out. These bolts will reduce the lateral flange movement during flange spreading.

1. Balance the wrench in your left hand and unlock the knurled handle by turning the locking knob anti-clockwise.

2. Set the torque amount by turning the knurled handle.

3. Install the proper socket and attach to the tool.

4. Pull handle until you feel or hear the wrench click.

Setting of ft-lb scale is done in the same way.

## Example: Set Torque Amount to 40–46 Nm

1. Turn the handle to 0 on the fine scale and until you reach 40 Nm on the base scale.

2. To set 46, turn the handle until you reach 6 on the fine scale.

3. Lock the handle by turning the locking knob clockwise.

WARNING

Do Not Pull After the Wrench Clicks

- Do not pull after the wrench clicks. Use special care at low torque settings. If the wrench has not been used for some time: operate it several times at low torque to allow internal lubricant to recoat. When not in use set to lowest torque setting. Do not turn handle below lowest torque setting. Your torque wrench is a precision measuring instrument and should be treated as such. Clean only by wiping, do not use any type of cleaner which may affect the special internal lubricant with which this wrench is packed at the factory.

WARNING

Do Not Attempt to Turn the Grip While It Is Locked

- Do not attempt to turn the grip while it is locked. Do not turn the grip more than one turn below the lowest scale reading or above the highest scale reading.

1. Determine the flange joint access gap – a minimum access gap of 6 mm (0.24") is required.

2. Insert the wedge into the joint until the heel of the step is in contact with the outer surface of the joint. Make sure that the full step is used and that the jaw is positioned centrally. Inserting the wedge incorrectly may result in tool breakage and render the warranty void. The rotating handle on the ACMS08T allows ease of access to the joint and can be rotated out of the way of any obstructions present.

3. It is strongly recommended that two ACMS08T wedges be used on the flange joint positioned 180 degrees apart. Turn each push rod in a clockwise direction using the torque wrench. Do this on each wedge in turn, ensuring the joint opens evenly. The torque wrench should be set at staged increases, ensuring both tools are applying similar forces, for example, 20 ft-lb, 40 ft-lb, and so on, until the maximum setting of 150 ft-lb is reached.

4. When the joint has been opened to the desired spreading distance, or the maximum spreading distance on the current step is reached, the safety block should be inserted into the joint and the pressure released back onto it.

5. The wedge can then be re-inserted on its next step and the joint opened further.

6. Once the joint has been spread and all work completed, the wedges should be removed by reversing steps 3–5. Make sure that the wedges are released evenly until completely closed. Care should be taken not to drop any of the component parts when removing them from the flange joint. This action will prevent injuries to either the operator’s lower limbs, or to passers-by.

# Stepped Block Accessory Installation and Operation

The Atlas Copco Stepped Block enables the ACMS08T and the ACHS14T to be used in a joint with a larger gap, and to be used to open a joint further with less penetration (allowing, for example, spectacle blinds to be changed with ease).

The stepped blocks can be used individually or as a pair.

1. Attach the stepped block to the tool using the M6 countersunk screw.

2. Insert the tool into the joint.

   Make sure that there is a minimum hold of 15 mm (0.59") and that the full width of the block is used.

# Service

# Maintenance Instructions

# Service Recommendations

- On return from each job and before allocation for later work, examine the completeness of the ACMS08T or ACHS14T kit. Also examine the items to make sure that they are serviceable.

- Replace any missing or damaged items as soon as possible and before using the tool again.

- Store the ACMS08T and ACHS14T in a cool dry place and make sure that all machined surfaces are greased.

- Grease all moving parts before use.

# Troubleshooting

# Troubleshooting the Tool

Problem | Possible Reason | Action
--- | --- | ---
The wedge is advancing but does not reach full pressure | Air could be present in the hydraulic system | Use the airlock removal procedure

Airlock Removal Procedure

1. Connect the hand pump to the tool with the hydraulic hose.

2. Close the release valve on the pump, and prime the pump until the hydraulic cylinder is fully extended and a small pressure is achieved.

3. With the hand pump held above the tool and the tool in an upright position, open the release valve causing any air that is within the system to be forced up through the pump and vented into the oil reservoir.

4. Repeat steps 1–3 three or four times to ensure that all air is removed from the system and the tool will reach full working pressure.

5. Disconnect the hand pump from the hydraulic hose, grip the baseplate of the hand pump body in a vice with the pump body vertical and the main handle at the top.

6. Remove the four nuts holding the main handle and lift off.

7. Grip the refilling plug with pliers and extract it by pulling and twisting simultaneously. Ensure the reservoir body is held down when removing the refilling plug as pulling up on the reservoir body will release the bladder within, and oil will spill out.

8. Fill the reservoir to the top with a good quality hydraulic oil of the grade 15 cSt.

9. Reinsert the refilling plug, wipe away any oil, and reassemble by reversing the disassembly process.
