# ATEX Certification Information

# Temperatures

- The maximum surrounding temperature for which the certification is valid is 40°C.

- 40°C is also the maximum allowed temperature of the compressed air when it enters the product.

- If the product is installed in an equipment, the entire equipment has to correspond to the guidelines 2014/34/EU.

- Make sure that the compressed air fulfil our quality demands (quality classes 2.4.3. and 3.4.4 respectively 3.5.4 acc. to ISO/DIS 8573-1:2010).

- Do not exceed maximum pressure of 6.3 bar, or as stated on the product nameplate. Exceeding the operating pressure can increase the surface temperature due to higher rotating speed and the product can become an ignition source.

# Ex Classification

If the product is part of an assembly where the components have different Ex classification, the component with the lowest level of safety defines the Ex classification of the complete assembly.

# ATEX Code Definition

The ATEX code is:
| Ex II 2 G Ex h IIC T2 Gb Ex II 2 D Ex h IIIC T240°C Db °C ≤ Ta ≤ 40 °C

Description | Value | Definition
--- | --- | ---
Equipment group | II | Surface Industry
Equipment category Group II | 2 | High level of protection zone 1 (gas) zone 2 (gas) zone 21 (dust) zone 22 (dust)
Atmosphere | G | Atmosphere containing Gas, Vapors or Mist
D | Atmosphere containing Dust
Safety design | h | Mechanical product
Gas group | IIC | Hydrogene/ Acetylene

# Explosion Prevention Guidelines

# Cleanliness

- Make sure the product is kept clean from dust and dirt to prevent increased bearing and surface temperature.

- If using a silencer: Make sure a silencer with a filtering effect at the air outlet is installed to prevent any friction-heated particles entering into the surrounding atmosphere.

# Usage

- Make sure the product is earthed to the equipotential bonding system of the workshop, for example through accessories such as hoses and air-pressure connections.

- It is the responsibility of the user to make sure that the product and all possible accessories, such as wrenches and air connections, conform to the national safety regulations for equipment used in potentially explosive areas.

# 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.

# Shaft Load Diagram

# Shaft Load

- Make sure that the maximum shaft load is not exceeded, in order to prevent an excessive increase of the bearing temperature.

# Installation Instructions

# Rotation

WARNING

Never run the motor without the restriction plates in place!

The restriction plates must be assembled on the engine in order for ATEX to be valid. If the restriction plates are removed, the motor will become overheated when in use.

In this Section

- Restrictors

# Restrictors

To achieve clockwise (CW) or counter clockwise (CCW) rotation, mount selected restrictor plates at the inlet/ outlet ports A and B. For reversible rotation (Rev) mount restrictor plates at the inlet port C and at the outlet ports A and B.

# 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

# Hot Spots

The following hotspots on the air motor can reach high temperatures during operation:

- motor housing

- seal ring at the output shaft

The highest temperatures occur when the air motor is running at full pressure without load. With increasing torque, the air motor reduces the rotational speed and the temperature.

# Service

# Maintenance Instructions

# Service Recommendations

Preventive maintenance is recommended at regular intervals. See the detailed information on preventive maintenance. If the product is not working properly, take it out of service and inspect it.

If no detailed information about preventive maintenance is included, follow these general guidelines:

- Clean appropriate parts accurately

- Replace any defective or worn parts

# Preventive Maintenance

# Overhaul

The air motor must be deactivated and inspected whenever there is the slightest indication of a fault. The service interval will vary, depending on motor speed and air quality. The first vane inspection should be carried out after 500 hours' running time. Inspect wear and tear of the vanes via the outlet port. If the vane's tapered part appear to be worn, we recommend service of the motor.

# Maintenance

Maintenance and repairs of this ATEX product must be carried out exclusively by authorised personnel, after which a no-load test and temperature measurements of hotspots (as seen in the figure) must be carried out and recorded in a report.

After a 5 min no-load test the surface temperature must not exceed the sum of 200°C + surrounding temperature, where the surrounding temperature can vary up to max 40°C.

# 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.

# Lubrication

Planetary gears, ball- and needle bearings and seal ring should be lubricated with grease in conjunction with the regular overhaul of the motor.

Always use lubricants of good quality. The oils and greases mentioned in the chart are examples of lubricants which are recommended.

# Recycling

# Environmental Regulations

When a product has served its purpose it has to be recycled properly. Dismantle the product and recycle the components in accordance with local legislation.

Batteries shall be taken care of by your national battery recovery organization.
