# Installation

# Installation Requirements

# Air Quality

- For optimum performance and maximum product life we recommend the use of compressed air with a maximum dew point of +10°C (50°F). We also recommend to install an Atlas Copco refrigeration type air dryer.

- Use a separate air filter which removes solid particles larger than 30 microns and more than 90% of liquid water. Install the filter as close as possible to the product and prior to any other air preparation units to avoid pressure drop.

For impulse/impact tools make sure to use lubricators adjusted for these tools. Regular lubricators will add too much oil and therefore decrease the tool performance due to too much oil in the motor.

Make sure that the hose and couplings are clean and free from dust before connecting to the tool.

Both lubricated and lubrication free products will benefit from a small quantity of oil supplied from a lubricator.

# Air Lubrication Guide

Recommended air lubricators:

- Atlas Copco Optimizer (1 liter) 9090 0000 04

- Q8 Chopin 46

- Q8 Chopin 32

- Shell Air Tool Oil S2 A 320

- Mobil SHC Cibus 32

# Compressed Air Connection

WARNING

Risk of severe injury

Air under pressure can cause injury.

- Always shut off the air supply when not in use or before any adjustments.

- Drain the hose of air pressure and disconnect the tool from air supply when not in use or before any adjustments.

- Always use the correct hose size and air pressure for the tool.

WARNING

Compressed Air

High air pressure can cause severe damage and bodily injury.

- Do not exceed maximum air pressure.

- Make sure that there are no damaged or loose hoses or fittings.

For correct air pressure and hose size, see the Technical Product Data on - https://servaid.atlascopco.com or www.atlascopco.com.

Make sure that the hose and couplings are clean and free from dust before connecting to the tool.

# Air Pressure Regulation

Make sure to adjust the regulator to the lowest expected pressure on the line.

Adjusting the air pressure will have the following consequences:

- Decreasing the air pressure will result in a slower but more accurate tool.

- Increasing the air pressure will result in a faster but less accurate tool.

If the pressure from the airline is below five bar, a tool from the EP L-series (designed for low pressure installations) is recommended.

# Installation Instructions

# Recommended hose sizes

Make sure that all connections, adapters and couplings exceed the recommended minimum inner diameter, corresponding to the recommended hose size of the tool. Refer to the examples in the table. Recommended hose size for a specific tool is found in "Technical specifications" in https://servaid.atlascopco.com

Recommended hose size | Minimum inner diameter for all couplings and adapters
--- | ---
8 mm | 7 mm
10 mm | 7 mm
13 mm | 9.4 mm

# Installation of Flexible Hose

To prevent tool vibrations use a flexible hose for compressed air with a minimum length of 300 mm (12") between the tool and the quick coupling.

# Initial Setting of Torque

To minimize the risk of damage to the actual joint we recommend to set the torque slightly lower on the test joint than the torque wanted for the application. Make sure to use the same equipment, such as for example extensions, sockets and air pressure on the test joint as will be used on the actual joint.

A | Torque transducer IRTT
B | Test joint
C | ST Analyzer

Make sure to always verify the torque settings on your actual joint.

# Operation

# Ergonomic Guidelines

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

- Take frequent breaks and change work positions frequently.

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

  - Adjust for convenient reach range by determining where parts or tools should 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 reducing the weight of the load. You can also reduce the load on the static muscles by holding the load close to the body.

  - Make sure to take frequent breaks.

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

- Adjust for convenient field of vision by minimizing movement of the eyes and head during the work task.

- Use the appropriate lighting for the work task.

- Use ear protection equipment in noisy environments.

- Use dust extraction system or mouth protection mask in dusty environments.

# Operating Instructions

# Torque Check - Residual Torque Measurement on Actual Joint

1. Make sure to use the same equipment, such as extensions, sockets and air pressure during the tightening, as will be used on the actual tightening application.

2. When performing a torque check on the actual joint we recommend using an ST Wrench with residual torque measurement* setting.

* Torque required to cause the threads of the fastener (including its head) on which torque is applied, to move relative to the mating thread.

A | The actual joint
B | Torque wrench with monitoring

1. Perform a tightening.

2. Measure the result with the Torque wrench with monitoring.

# Optimizing the Tool Performance

It is not recommended to use extensions with pulse tools. Extensions cause vibrations, which in turn may cause wear on the tool, longer tightening time, limited accuracy and difficulty reaching maximum torque. If an extension is necessary due to accessibility constraints, it should be as short as possible. Guided sockets or extensions are strongly recommended.

## Recommended number of pulses

The pulse tool shall reach the target torque, with shut off, within 5-20 pulses. Measure the number of pulses to reach the target torque with an analyzer. The tightening time can also be used as a guide, to know if the tool is set correctly:

- ≤ 1 second for tools up to 30 Nm

- ≈ 1 second for tools up to 80 Nm

- ≈ 2 seconds for tools up to 150 Nm

- ≈ 5 seconds for tools up to 450 Nm

- ≤ 10 seconds for tools up to 850 Nm

If the target torque is reached within less than 5 pulses (= short tightening time), the torque scatter will increase and it can be difficult to adjust to the right level, especially on hard joints.

If the target torque is reached after more than 20 pulses (= too long tightening time) the wear will increase and more frequent oil filling and service will be required. Too long tightening time, in combination with high production rate, may also result in excessive heating of the oil. In that case the power will decrease with longer tightening time and sometimes no shut off.

If the target torque is reached within less than 5 pulses, adjust it by:

- Decreasing the air pressure.

- Reducing the speed with the AutoTrim or Trim valve.

- If the above is not possible or does not give the wanted results, a smaller tool may be a better choice.

If the target torque is reached with more than 20 pulses, adjust it by:

- Increasing the dynamic air pressure to 6-7 bar for standard EP tools, or up to 5 bar for low pressure EP L-tools.

- Adjusting the AutoTrim or Trim valve to give maximum power/speed.

- If the above is not possible or does not give the wanted results, a bigger tool may be a better choice.

When changing the air pressure, measure the target torque again and adjust it if needed.

# Setting of tightening torque

The adjusting screw is accessible through the hole in the housing. If necessary, turn the outgoing spindle.

After adjusting, it is important to remember to assemble the plug of the hole in the housing.

It is recommended to start at min. torque setting - when the adjustment screw is screwed out approx. 6 turns from the bottom position. Do not screw out any further.

When using the machine above recommended maximum torque it might result in improper function and faster wear. Always check the setting on your actual joint.

# Operating Instructions

# Service

# Maintenance Instructions

# Service tools

Atlas Copco Service tools are designed to make assembly and disassembly fast and easy with less risk of damaging parts in the process.

When assembling the tool after service it is important to tighten the parts correctly to:

- Optimize performance of the tool.

- Minimize the risk of parts coming loose during operation.

You can find information about service tools and tightening data in the Spare part list on ServAid.

# Preventive Maintenance

Preventive maintenance is recommended once per year or after a maximum of 250.000 tightenings. A complete overhaul includes:

- Clean the following parts: pulse unit, air motor, silencer and strainer of the inlet adapter, trigger and reversing valve.

- Replace worn or damaged parts and filter.

Only replace the o-rings in the pulse unit at the complete overhaul.

# Lubrication Instructions

# Rust Protection and Cleaning

Water in the compressed air can cause rust. To prevent rust we strongly recommend to install an air dryer.

Water and particles can cause sticking of vanes and valves. This can be prevented by installing an air filter close to the product to avoid pressure drop.

Before longer stand stills always protect your tool by adding a few drops of air motor oil into the air inlet. Run the tool for 5–10 seconds and absorb any excess oil at the air outlet in a cloth.

# To fill the pulse unit with oil

Due to a possible microleakage of oil from the pulse unit, it could be necessary to refill the unit between the regular overhaul intervals. The frequency of this procedure depends on the type of application, number of cycles, tightening time etc. An indication of not enough oil is a decreased tightening torque and an increased pulse frequency.

After disassembly of pulse unit, fill with oil according to operation No. 1-3 below. Run the machine in a vice for 10 seconds according to operation No. 5 below. Then continue according to operation No. 6-11. For best performance use Atlas Copco pulse unit oil Bio. The Oil Filling Kit is composed of Atlas Copco Pulse unit oil Bio 150 ml and a syringe (1 ml). Ordering No. : 4081 0121 90.

# To refill the pulse unit

Keep the pulse unit at normal room temperature.

Before the refill: Let the bubbles in the oil fade away, at least 30 min. after last run. Check that there are no bubbles in the oil and that the pulse unit is completely full (100%) before reducing the oil volume according to operation No. 10.

Correct oil quantity: Fill to 100%, then reduce according to table. After the refill - check the tightening torque, and pulse frequency according to test methods.

Oil volume to be reduced from 100% | Approx. oil volume in pulse-unit
--- | ---
0.6 ± 0.05 ml | 9.5 ml

# Dismantling/Assembling Instructions

# Tightening of Threaded Connections

The tightening torque indicated in the exploded views (see Spare parts section in https://servaid.atlascopco.com) will give the right clamping force and prevent parts from loosening. It is important not to exceed the clamping force, these parts must be able to open up without being damaged at service. After some time of operation and in special circumstances, depending on application and usage, the parts may however loosen somewhat. The tightening torque can then be increased by 10-20% and some type of low or medium thread locking fluid can be applied.

# Torque Check - Residual Torque Measurement on Actual Joint

1. Make sure to use the same equipment, such as extensions, sockets and air pressure during the tightening, as will be used on the actual tightening application.

2. When performing a torque check on the actual joint we recommend using an ST Wrench with residual torque measurement* setting.
