Technical Specifications

Torque and Fastening Data

The Atlas Copco LMS08 SR42 delivers a maximum torque of 44 ft-lb .
Its torque range starts at 5 ft-lb and reaches up to 26 ft-lb .
For smaller fasteners, the minimum bolt size capacity is 6 mm .
In contrast, the maximum bolt size capacity reaches 8 mm for standard tasks.
Consequently, this tool suits automotive assembly, maintenance, and repair applications.

Impact and Speed Data

Impacts per minute equal 1650 for consistent fastening performance.
The model type is straight, which enables inline operation and better access.
Output type is hexagon female for standard impact socket attachment.
Output size measures 1/4" , making it compatible with common sockets.
Additionally, the quick change chuck accepts 1/4 in bits for fast swaps.

Air Consumption Requirements

Air consumption equals 9.1 cfm under normal operating conditions.
Maximum working pressure is 90 psi to ensure safe operation.
For adequate airflow, the recommended hose size is 6.3 mm .
The air inlet thread measures 1/4 in for standard shop fittings.
Always use clean, dry, and lubricated air for best performance.
Consequently, the LMS08 SR42 requires proper air filtration upstream.

Dimensions and Weight

Length measures 185 mm , which allows compact tool handling.
Center to side (CS) distance equals 20 mm for better access in tight spaces.
Package dimensions are 34.9 cm x 10.8 cm x 8.3 cm for reference.
Package weight equals 1.17 kg , making shipping cost-effective.
Meanwhile, the tool weight is 1.9 lb for comfortable operator use.

Noise and Vibration Data

Sound power level equals 96 dB(A) during normal operation.
Similarly, sound pressure level equals 85 dB(A) at the operator position.
Sound measurement follows ISO15744 standard methodology.
The sound uncertainty is 3 dB(A) for measurement tolerance.
According to ISO28927-2, the vibration value equals 5.6 m/s² .
This vibration level allows extended use without causing excessive fatigue.

Design Features

The Atlas Copco LMS08 SR42 uses a non shut-off impact mechanism.
This design continues impacting until the operator releases the trigger.
Therefore, the tool suits high-speed disassembly and assembly tasks exceptionally well.
The Grease Retaining System keeps lubrication inside the mechanism.
This system prevents grease from escaping during high-speed operation.
As a result, the LMS08 SR42 maintains consistent performance over extended periods.
The straight handle design provides natural wrist alignment for operator comfort.
Finally, the hexagon female output accepts standard 1/4" impact sockets.

Certifications and Standards

The Atlas Copco LMS08 SR42 holds EAC certified status for Eurasian markets.
Moreover, it complies with EU Legislation 2006/42/EC for machinery safety.
The tool meets EU Standard EN ISO 11148-6:2012 for hand-held non-electric tools.
For UK regulations, it follows S.I. 2008/1597 as required.
Similarly, the UK Standard also follows EN ISO 11148-6:2012 .
Therefore, the LMS08 SR42 meets strict European and UK safety requirements.

Installation and Setup Guidelines

First, connect the Atlas Copco LMS08 SR42 to a clean air supply only.
Next, install a filter-regulator-lubricator (FRL) unit upstream of the tool.
Set the regulator to 90 psi as the maximum working pressure.
Use a 1/4" NPT quick-connect coupling for the air inlet connection.
Before first use, apply 2-3 drops of pneumatic tool oil into the inlet.
For the hose, use minimum 6.3 mm internal diameter for adequate flow.
Keep air hose length under 10 meters to maintain full power.
Do not exceed the maximum torque rating of 44 ft-lb during use.
Use only impact-rated sockets on the LMS08 SR42 for safety.
Finally, inspect the tool daily for air leaks or any visible damage.

Frequently Asked Questions (FAQ)

1. Can the LMS08 SR42 achieve the maximum torque continuously?

No, the Atlas Copco LMS08 SR42 reaches 44 ft-lb peak torque intermittently. Continuous operation at maximum torque may reduce the tool's service life.

2. Does this tool require a shut-off mechanism for precision work?

No, the LMS08 SR42 is a non shut-off impact wrench. For torque control, you need an external torque limiter or skilled operator technique.

3. What is the Grease Retaining System on this model?

This system keeps lubricant inside the impact mechanism. Consequently, the Atlas Copco LMS08 SR42 runs longer between required service intervals.

4. Is this tool suitable for use in explosive atmospheres?

No, pneumatic tools can generate sparks on impact. Therefore, the LMS08 SR42 is not rated for hazardous or explosive environments.

5. How often should I lubricate the LMS08 SR42?

Lubricate the Atlas Copco LMS08 SR42 daily through the air inlet. Use 2-3 drops of quality pneumatic tool oil before each use session.
