PTFE
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
►Wash your hands before starting any other activity
Country of Origin

Installation EN LSF19 S300-1

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 lu-
bricator.
Air Lubrication Guide
Recommended air lubricators:
■Atlas Copco Optimizer (1 liter) 9090 0000 04
■Q8 Chopin 46
■Shell Air Tool Oil S2 A 320
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.

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 vibra-
tion.
■Minimize exposure to reaction forces.
■When cutting:
A cut-off wheel can get stuck if the cut-off wheel is bent or not guided properly. Use the correct
flange for the cut-off wheel and avoid bending the cut-off wheel during operation.
■When drilling:
The drill might stall when the drill bit breaks through. Use support handles if the stall torque is high.
The safety standard ISO11148 part 3 recommends using a device to absorb a reaction torque
above 10 Nm for pistol grip tools and 4 Nm for straight tools.
■When using direct-driven screwdrivers or nutrunners:
Reaction forces depend on the tool settings and joint characteristics. Strength and posture deter-
mine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the op-
erator's strength and posture and use a torque arm or reaction bar if the torque is too high.
■In dusty environments, use a dust extraction system or wear a mouth protection mask.

Setting-up instructions
WARNING Risk of Serious Injury or Death
Overspeed can cause serious injury or death!
►Do not manipulate the speed of the tool.
►Do not override the maximum speed marked on the tool.
Testing of the die grinder should only be done by professional technicians. The technicians must be au-
thorized to test this type of tool and to operate a pneumatic system in accordance with national directives.
■Do a free speed check of the tool every day and whenever the tool has been serviced. Do the free
speed check with the grinding equipment removed.
■Use a pressure regulator to prevent a too high air pressure which can cause overspeed.

Operation EN LSF19 S300-1
10 © Atlas Copco Industrial Technique AB - 9836 6287 01
■Make sure that connections and the air hose are in good condition.
Throttle Lever with Safety Trigger
The purpose of a throttle lever with safety trigger is to avoid unintentional start of the tool.
Flip the safety trigger to lock/unlock the safety function. Always put the throttle lever in locked position
before putting away the tool.
■Make sure that the safety trigger works correctly.
■Replace the throttle lever if it does not work correctly.
■Never remove the safety trigger or lock it with tape.

Service
Maintenance Instructions
General Service and Maintenance Safety
Do not dismantle the tool.
The service must only be done by authorized workshops or qualified service technicians.
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.
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 guide-
lines:
■Clean appropriate parts accurately
■Replace any defective or worn parts
Replacement of Vanes
Replace the vanes in the motor when a power drop of the tool is experienced. If the vanes are not re-
placed in time other motor parts may be damaged. For increased life length of the vanes use an oil lubri-
cator to dose oil into the air inlet.
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.
NOTICE Do not try to clear the air path using sharp tools.
The air inlet is equipped with a strainer. If this is punctured, foreign objects may harm the valves, resulting
in overspeed.
Lubrication
For flexible spindle extension – When fitting the extended spindle – apply 0.5 cm3 (0.03 cu in) of grease
type “Lubricating Engineers LE3752” (or EP grease) at the bottom of the hole in the collet holder.

Lubrication Guide
Use lubricants of good quality. The oils and greases listed in the lubrication table are examples of lubri-
cants that can be recommended.
