# Overview

# Applications

Torque arms are used for assistance when operating hand held tools such as screwdrivers and nutrunners. The torque arms in the SMC series have a large working range, are easy to position and handle. They are designed for heavy duty operations over a long period of time. The torque arms makes assembly more stable and reduces wear on accessories like bits and taps. It is recommended to use the SMC series of torque arms together with a balancer.

The torque arms reduces the strain on the operators arm, wrist and shoulder by reducing vibration, torque and weight during repeated actions. Even small amounts of repeated actions can lead to repetitive strain injury.

# Installation

# Installation Requirements

# Working area when mounted on a ceiling

ω: Max tool holder swivel angle

# Installation Instructions

# Attaching and balancing the tool when mounted on a bench

Do not use SMC 200 and SMC 300 with a bench stand.

1. Adjust the height of the arm relative to the work piece. It is recommended to mount the arm attachment at the same height as where the torque is applied.

2. Attach the tool holder to the tool.

3. Attach the tool holder to the arm. Install the screw and tighten it:

   - SMC 12/25 (M6) - 10 Nm

   - SMC 50/100 (M8) - 24 Nm

4. Install the set screw on the tool holder and tighten it to 2.5 Nm.

5. Balance the tool with the balancer.

# Installing the torque arm

The tool torque should not exceed the specified torque range of each specific arm.

Do not use SMC 200 and SMC 300 with a bench stand.

Mounting on a bench

- Find the optimal position for the operator to handle the torque arm.

- Install the torque arm straight in front of the operator or alternatively to the left or right depending on whether the operator is left or right-handed.

- Firmly tighten the screws in the holder that connects the torque arm to the bench stand. The bench stand is pre-drilled for fixing to a bench.

- Attach the safety wire (see Spare Parts) to a second point that does not limit the working area.

Mounting on a ceiling

- Put the mounting point straight above, or as close as possible to, the point where the torque is applied.

- Make sure that the fixation point can handle the weight and the torque of the chosen torque arm.

- Attach the safety wire (see Spare Parts) to a second point that does not limit the working area.

# Working area when mounted on a bench

# Attaching and balancing the tool when mounted on the ceiling

1. Mount the arm straight above, or as close as possible to the work area.

2. Attach the tool holder to the tool.

3. Attach the tool holder to the arm.

4. Install the set screw on the tool holder and tighten it to 2.5 Nm.

5. Attach a balancer to the torque arm by using Atlas Copco balancer adapter kit and hook it up with the tool.

6. Adjust the balancer to carry the weight of the torque arm, the tool holder and the tool.

7. Adjust the wire stop of the balancer so that the torque arm cannot be fully retracted.

8. Secure all the screws with the set screws (Refer Spare Parts list for more details).

# Installing the SMC torque arms in trolley and rail systems

Do not modify the torque arm or the torque arm attachment. The installed torque arm must be able to swivel in all directions.

# Operation

# Operating the torque arm

Make sure that the tool holder is correctly tightened before using the torque arm.

When using the torque arm the first time, start at a low tool torque to get used to how to operate the torque arm.

WARNING

Risk of injury

Unexpected movements can cause injury.

- Before operating, lock the torque arm attachment in a fixed position.

NOTICE

Risk of damage

A hit against the rail ends will cause damage to the torque arm.

- Do not use excessive force on the torque arm.
