Overview
Applications
This powerful, high-speed impact wrench (LMS) is typically used for loosening applications where fast tight-
ening or disassembly is needed.
Service intervals
Service recommendations
Overhaul and preventive maintenance is recommended at regular intervals. See the Preventive maintenance
section for detailed information regarding overhaul of your tool and specic parts. If the machine is not working
properly, it should immediately be taken away for inspection. At the overhauls, all parts should be cleaned ac-
curately and defective or worn parts should be replaced.

Installation requirement
General
The machine is designed for a working pressure (e) of 6.3 - 7 bar (max.) = 630 - 700 kPa (90 - 102 psi).
If the compressed air line pressure is higher than 7 bar it is preferable reduced with a pressure regulator of
the type Atlas Copco REG.
The Atlas Copco Air Line Test equipment is suitable for checking of air pressure and airow at the installation
point (please see AirLine Accessories in our main catalogue).
The machine can operate at a lower working pressure. Maximum torque will be reduced at lower pressures.
AIf frequent used for tightening or loosening that need longer time than 3-5 seconds, a larger wrench
should be used. Otherwise the servicelife of the impact mechanism will be reduced.
To avoid pressure drop use recommended hosesize, length, and connections. For more information please read
Atlas Copco Airline Installations, Ordering No. 9833 1191 01.
Air quality
• For optimum performance and maximum machine life we recommend the use of compressed air with a
maximum dew point of +10°C. We also recommend the installation of an Atlas Copco refrigeration-type air
dryer.
• Use a separate air lter of type Atlas Copco FIL. This lter removes solid particles larger than 15 microns
and also removes more than 90 % of liquid water. The lter must be installed as close as possible to the
machine/equipment and prior to any other air preparation unit such as REG or DIM (please see Air Line
Accessories in our main catalogue). Blow out the hose before connecting.
Models which need air lubrication:
• The compressed air must contain a small quantity of oil.
We strongly recommend that you install an Atlas Copco oil-fog lubricator (DIM). This should be set according
to air consumption by the air line tool according to the following formula:
L= Air consumption (litre/s).
(May be found in our sales literature).
D= Number of drops per min (1 drop = 15 mm3)
L* 0.2 = D
this applies to the use of long work cycle air line tools. A single point lubricator type Atlas Copco Dosol can
also be used for tools with short running cycles.
Information about Dosol settings may be found under Air Line Accessories in our main catalogue.
Lubrication-free models:
• In the case of lubrication-free tools it is up to the customer to decide on the peripheral equipment to be used.
However, it is no disadvantage if the compressed air contains a small quantity of oil e.g. supplied from a fog
lubricator (DIM) or Dosol system. This does not apply to turbine tools, which should be kept oil free.
Installation proposal
Choosing the correct couplings, hose and clamps can be a troublesome digging into details. To save your time
and to ensure correct capacity of the airline installation, from the tapping point to the tool, we offer you an in-
stallation proposal.

Ergonomics
Ergonomic guidelines
1)Take frequent breaks and change work positions frequently.
2)Adapt the workstation 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
motion.
• Use workstation equipment such as tables and chairs appropriate for the work task.
3)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
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.
• Make sure to take frequent breaks.
• Avoid extreme arm or wrist postures, particularly for operations requiring a degree of force.
4)Adjust for convenient eld of vision by minimizing movement of the eyes and head during the work task.
5)Use the appropriate lighting for the work task.
6)Select the appropriate tool for the work task.
7)Use ear protection equipment in noisy environments.
8)Use high-quality inserted tools or consumables to minimize exposure to excessive levels of vibrations.
9)Minimize exposure to reaction forces.
• When cutting:
A cut-off wheel can get stuck if the wheel is either bent or if it is not guided properly. Make sure to use
correct anges for cut-off wheels and avoid bending the wheel during cut-off operation.
• When drilling:
The drill might stall when the drill bit breaks through. Makes sure you use support handles if the stall
torque is too high. The safety standard ISO11148 part 3 recommends to use something to absorb the reaction
torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
• When using direct driven screw or nutrunners:
Reaction forces depend on tool setting and joint characteristics. The ability to bear reaction forces depends
on the operator’s strength and posture. Adapt the torque setting to the operator's strength and posture and
use a torque arm or reaction bar if the torque is too high.
10)Use dust extraction system or mouth protection mask in dusty environments.
Operating instructions
Tightening torque
The tightening torque attained depends on the air pressure, tightening time and bolted joint in question. Extension
pieces and worn sockets will reduce the effective tightening torque. Oversized power sockets (diameter and or
length) will overload the impact mechanism and reduce the life of vital parts as the impact mechanism. The
impact wrench must be used within the specied torque range. Never exceed the recommended maximum
tightening torque.
Test methods
Measurement using a hydraulic Torque Tension tester is recommended for testing tool performance, see Test
data.

LMS88 GIR38ENOperation

Maintenance
Service instructions
Overhaul and preventive maintenance are recommended at regular inter-
vals once a year or after max. 100 000 tightening operations at the latest,
whichever comes rst. More frequent overhauls may be required if the
machine is used for heavy-duty applications. If the machine fails to
function correctly, it must be decommissioned immediately for inspec-
tion.
The strainer at the air inlet must be cleaned regularly in order to pre-
vent clogging due to contamination. The machine capacity will otherwise
be reduced.
All parts must be cleaned thoroughly during overhaul work and defect-
ive or worn parts must be replaced
It is important to ensure that the threaded connections on the machine
are tightened properly; i.e. in accordance with the specications in the
exploded views. Lubricate the threads with grease prior to tting.
AAll O-rings must be greased prior to assembly.
The motor has to be lubricated with oil from the handle's oil chamber
unless a permanent air lubrication device is installed. Check daily to
ensure that the oil chamber is lled and that the discharge air contains
a sufcient amount of oil. See Handle.
When the machine is in constant operation, installation of an Atlas
Copco DIM oil mist lubricating device or a Dosol type single point
lubricating device is recommended.
Impact mechanism
Check the specied wear limits and replace all parts which exceed these.
See Inspection.
ARecommended maximum wear limits for the clutch jaw, anvil
and driver.
Rust protection and internal cleaning
Water in the compressed air, dust and wear particles cause rust and
sticking of vanes, valves etc. An air lter should be installed close to
the machine (see 'Air quality'). Before longer standstills, ush with oil
(some drops) into the air inlet, run the machine for 5-10 seconds when
absorbing the oil in a cloth.
How to optimize service and performance of your
impact wrench
The service life of the impact mechanism is mainly de-
pendent on:
•service intervals
•air pressure
•tightening time/torque
•number of tightening
•socket/bolt size
•socket length
7

ServiceENLMS88 GIR38

Service intervals
Shorter service intervals with cleaning and lubrication of the impact
parts will improve the function and reduce the wear. Follow our service
recommendations.
Air pressure, tightening time/torque and number of tightening
It is obvious that wear will increase with increased air pressure, longer
tightening time/higher torque and number of tightening.
A tightening time of 1-5 seconds is recommended. The Skidmore-
Wilhelm table in Test data can be used as a guide for max. tightening
time.
Longer tightening or loosening times will increase wear, producing
malfunction and risk of breakage.
Socket and bolt size
Each impact wrench covers a certain bolt size range. The impact mech-
anism parts have been designed for good durability in combination with
the recommended standard socket/bolt size.
Usage of oversized sockets/bolts will increase premature wear and
risk of breakage.
If frequent square drive breakages occur and different square drive
sizes are avaliable, use the largest size.
Long sockets/extensions
It is better to use extensions + standard socket instead of long or extra
long sockets as the lower inertia /mass of the extension will give less
stress on the impact mechanism. However an extension will reduce the
applied torque to some degree.
