Overview
General properties
Atlas Copco torque arms are an excellent means of assistance when using electric or pneumatic screwdrivers and nutrunners. They stress relieve the operators arm, wrist and shoulder from vibration, torque and weight during repeated actions. Even at a modest level of exertion repeated actions can lead to severe disorders. As an additional advantage the Atlas Copco torque arms also make savings on the tool accessories e.g.bits, taps etc. due to entering the screw or the hole more in right angle.
Torque arms in the SMS series have a large working range and are exceptionally easy to position and handle. The design is intended for heavy duty operations over a long period of time.Tool torque should not exceed the specified torque range of each specific arm.

Installation
Installation Instructions
Installing the torque arm
Before you start the installation, measure the applicable position of the torque arm for your working area.
Fasten the torque arm base with 4 screws (not supplied) on a perfectly horizontal bench. Tighten the screws until the torque arm is properly seated.
Installing the digital top encoder
Put the encoder with coupling on the shaft at the top of the vertical arm.
Tighten the flanges with the screws.
Carefully tighten the clamping hup with the screw.
Fasten the protection over the encoder with the screws.
Connect the encoder to the Turck I/O Module.
Installing the torque arm attachment
Before you start the installation, measure the applicable position of the torque arm for your working area.
Fasten the torque arm base with screws (not supplied) on a horizontal bench. Tighten the screws until the torque arm is properly seated.
Fasten the horizontal arm on the vertical arm with the screws. Select the applicable holes on the arm for optimal operation within your working area.
Choose the tool holder orientation.
Fasten the tool holder at the end of the horizontal arm with the screws. Tighten the screws with the recommended torque.
Attach the tool to the tool holder on the recommended tool clamp area with the screws. Tighten the screws to the recommended torque. For more information about correct tool clamp area and recommended torque, see the applicable tool Product Instruction or contact your local Atlas Copco representative.
Set the balancer. Turn the wheel on the balancer to get the optimum resistance (depending on the tool). The tool can at this time be connected to the power supply.

Installing the balancer
Before you start the installation, measure the applicable position of the torque arm for your working area.
Depending on the size and weight of the parts to be installed, a second person will be required to help to carry out installation step No.4.
After the foot part (1) has been fastened, the horizontal unit (2) is pushed onto the upright shaft (3).
Place the collar(4) onto the shaft (3) and let it rest on the horizontal unit (2) while performing the next steps.
Now install the balancer (5). To do this, the spring hook (4) is hooked into the link of the horizontal unit (2).
Lift the horizontal unit (2) until the balancer (5) can be inserted into the upright shaft (3).
Slide the collar along the shaft (3) until it's 1-2 mm beneath the balancer(6) unit.
Tighten the screw until the slight resistance is felt and twist the collar into its final position. Make sure the collar is correctly seated below the balancer.
Fully tighten the screw to the recommended torque (m6 = 10 Nm, m8 = 20 Nm, m10 = 20 Nm). Use appropriate torque wrench. When tight a gap should remain in the clamp portion of the collar. Take care, not to over tighten. over tightening could damage the collar which would lead to a decrease in the performance or failure.
