LMS18 HR13/F Atlas Copco Pneumatic Impact Wrench

Atlas Copco LMS18 HR13/F Pneumatic Impact Wrench 1/2"

Product Introduction

The LMS18 HR13/F from Atlas Copco is a pistol-grip pneumatic impact wrench. This non shut-off tool handles medium-duty fastening applications with ease. It delivers excellent power relative to its compact size. The unique Grease Retaining System keeps the tool performing reliably for longer periods. Moreover, you feel very little reaction force during operation. This makes the LMS18 HR13/F perfect for assembly lines, maintenance shops, and field service work.

Key Technical Specifications

This impact wrench drives 10 mm bolts (minimum and maximum). Maximum torque reaches 110 ft-lb (approximately 150 Nm). The torque range is adjustable from 7 ft-lb to 81 ft-lb. Free speed is 8100 r/min. Impact rate is 1500 blows per minute. Output size is 1/2" with a male square drive type. The tool length measures only 144 mm. Center to side (CS Distance) is 26 mm.

For air requirements, consumption is 18 cfm at maximum load. Maximum working pressure is 100 psi. The air inlet thread is 1/4". Recommended hose size is 10 mm. The tool weighs 3.2 lb (approximately 1.45 kg). Package weight including accessories and case is 1.86 kg. Country of origin is Hungary (HU).

Design and Function Features

The LMS18 HR13/F uses a pistol grip housing for superior control and comfort. This ergonomic design reduces operator fatigue during extended use. It has no automatic shut-off, giving you full manual control over fastening time. The Grease Retaining System is a standout feature. It holds lubricant exactly where moving parts need it. Consequently, service intervals become longer and tool life increases significantly. The compact length of 144 mm allows access to tight spaces where larger tools cannot fit.

Noise and Vibration Data

Sound pressure level is 90 dB(A) with a sound power level of 101 dB(A). Both measurements follow ISO15744 standard. Uncertainty is 3 dB(A). Vibration value is 5.3 m/s² according to ISO28927-2. Vibration uncertainty is not specified by the manufacturer. These figures are typical for tools in this class. Operators should wear hearing protection and take regular breaks to manage vibration exposure.

Certifications and Compliance

The Atlas Copco LMS18 HR13/F meets EU Directive 2006/42/EC (Machinery Directive). It complies with EU Standard EN ISO 11148-6:2012 for hand-held non-electric power tools. For the UK market, it follows S.I. 2008/1597 regulations and the same EN ISO 11148-6:2012 standard. EAC certification is also confirmed, allowing sales in Eurasian Customs Union countries.

Installation and Operating Guidelines

Connect the LMS18 HR13/F to a clean, lubricated air supply regulated to 100 psi maximum. Use a 1/4" air hose with 10 mm inner diameter. Install a filter-regulator-lubricator (FRL) unit upstream. For best performance, add 2-3 drops of pneumatic tool oil per hour of operation. Insert a 1/2" square drive socket onto the male output. Apply the tool to the nut or bolt. Squeeze the trigger and run the tool until the desired tightness is reached. Since this is a non shut-off wrench, release the trigger immediately after reaching torque to avoid over-tightening.

Frequently Asked Questions (FAQ)

1. What size bolts can the LMS18 HR13/F handle?
The LMS18 HR13/F handles 10 mm bolts. It is designed for medium-duty fastening applications such as automotive assembly, small machinery maintenance, and general repair work.

2. Is this tool suitable for tire shops?
Yes, the LMS18 HR13/F works well for passenger car and light truck tire changes. Its 110 ft-lb max torque handles most lug nuts easily. However, for heavy truck tires, consider a larger model like the LMS38 series.

3. Does the pistol grip make a difference in comfort?
Yes, the pistol grip design reduces wrist strain compared to straight tools. It also provides better control in overhead or vertical applications. Many users prefer the LMS18 HR13/F for all-day use because of this ergonomic advantage.

4. How does the Grease Retaining System benefit me?
The system keeps grease inside the impact mechanism longer. This reduces lubrication frequency and extends service intervals. In daily shop use, this means less downtime for maintenance and a longer overall tool life.

5. Can I adjust the torque output?
Yes, you can adjust torque by varying air pressure, using different impact sockets, or controlling trigger time. The torque range is specified from 7 ft-lb to 81 ft-lb for precise applications. For maximum torque of 110 ft-lb, run the tool at full pressure until the fastener stops moving.
