Warning
WARNING Polymer hazard
The vanes in this product contain PTFE (a synthetic fluoropolymer). Due to wear, there might be
PTFE particles inside the product. Heated PTFE can produce fumes which may cause polymer fume
fever with flu-like symptoms, especially when smoking contaminated tobacco.
Health and Safety recommendations for PTFE must be followed when handling vanes and other com-
ponents:
►Do not smoke when servicing this product
►PTFE-particles must not come in contact with open fire, glow or heat
►Motor components must be washed with cleaning fluid and not blown clear with an air line

Service overview
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
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 respec-
tively 3.5.4 acc. to ISO/DIS 8573-1).

LZB22-L-A049-11 ATEX EN Product information

■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 prod-
uct can become an ignition source.
Ex Classification
If the product is part of an assembly where the components have different Ex classification, the compo-
nent with the lowest level of safety defines the Ex classification of the complete assembly.

Explosion prevention guidelines
Cleanliness
■Make sure the product is kept clean from dust and dirt to prevent increased bearing and surface tem-
perature.

■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 po-
tentially 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.
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 lu-
bricator.

Compressed air connection
WARNING Compressed air can cause serious injury
►Always shut off the air supply, drain hose of air pressure and disconnect the tool from air supply;
when not in use, before making any adjustments to the product - for example changing acces-
sories, or when making repairs.
WARNING Whipping hoses can cause serious injury
►Always make sure that there are no damaged or loose hoses or fittings.
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 section Technical data.
Make sure that the hose and couplings are clean and free from dust before connecting to the tool.

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

Connecting the air supply
When the compressed air supply is connected to the inlet, the direction of rotation will be as shown in the
figure below. If the exhaust air is to be piped away, a hose should be connected to the exhaust outlet.

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 motor (as seen in the figure) can reach high temperatures during operation:
■Seal ring at the output shaft
■Joint between front part and gear ring
■Key grip
Straight models

Operation EN LZB22-L-A049-11 ATEX
12 © Atlas Copco Industrial Technique AB - 9836 6679 01
Angled models
The highest temperatures occur when the motor is running at full pressure without load. With increasing
torque, the air motor reduces the rotational speed and the temperature.

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
Overhaul
To achieve the best engine service life under normal operating conditions, regular overhaul and cleaning
should be carried out every 12 months or after every 1000 hours (lubrication free models) or 2000 hours
(standard models) of operation, whichever is the sooner. Overhaul should be carried out more frequently
under more rigorous operating conditions.
Clean the engine thoroughly.
Fit the engine and check that it rotates freely. Pour two drops of oil into the air intake and idle the en-
gine for 5-10 seconds.
If the compressed air is very dry, the idle speed for lubricant-free engines may decrease slightly after
fairly long periods of operation. This decrease may amount to 10-15%.
Maintenance
■Maintenance and repairs of this ATEX product must be carried out exclusively by authorised person-
nel, 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 45°C + surrounding
temperature, where the surrounding temperature can vary between 0 – 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 fil-
ter close to the product to avoid pressure drop.
Before longer standstills always protect your tool by adding a few drops of oil into the air inlet. Run the tool
for 5–10 seconds and absorb any access oil at the air outlet in a cloth.

with the regular overhaul of the motor.
Always use lubricants of good quality. The oils and greases mentioned in the chart are examples of lubri-
cants which are recommended.
