Key Features

• Wide torque coverage: The family ranges from lighter models with 10-90 Nm to heavy-duty versions with 600-1800 Nm working torque.
• Drive size options: Models are available with 3/8, 1/2, and 1 inch drives to suit different bolts and applications.
• Retainer choices: Versions are offered with retainer types a, b, or c depending on handling preference.
• Compact build: The tools are relatively short, with lengths from 144 mm to 252 mm excluding the anvil, depending on the model.
• Air consumption spread: Air demand ranges from 6.5 to 28 L/s, which helps match the tool to the available air supply.
• Weight range: Weight runs from 1.45 kg to 9.8 kg, allowing selection between lighter handheld use and heavier high-torque work.

Frequently Asked Questions

How do I choose the right LMS HR model?
Step 1: Identify the torque range required for the joint.
Step 2: Check the bolt size and the needed drive size.
Step 3: Compare air consumption, tool length, and weight against the workstation conditions.
Step 4: Select the retainer type that fits your handling preference.

Should I choose 3/8, 1/2, or 1 inch drive?
Choose the drive size based on bolt size and application load.
The smaller models use 3/8 drive, mid-range models use 1/2 drive, and the heaviest models use 1 inch drive.

What is the difference between the light and heavy models?
The lighter models offer lower to mid torque, lower weight, and lower air demand.
The heavy models are intended for larger bolts and much higher torque levels.

How do I choose between retainer types a, b, and c?
The choice depends on how you prefer the socket to be held and managed on the line.
Match the retainer style to the handling method used at the station.

What should I check in the air system before installation?
Make sure the air line can supply the model’s required air consumption.
Also check the recommended hose size and the correct air inlet thread.

What comes with an LMS HR model?
Each model is supplied as a defined pneumatic torque wrench with its own ordering number.
The differences between models are drive size, torque range, weight, length, and air consumption.
