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 recom-
mended 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 instructions
Installing the torque arm
The tool torque should not exceed the specified torque range of each spe-
cific arm.
Do not use SMC 200 and SMC 300 with a bench stand.
The angle ω is limited to 0° at SMC position L/LA to achieve proper accu-
racy for positioning.
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.
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 ap-
plied.
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.

5. Adjust the balancer to carry the weight of the torque arm, the tool holder
and the tool.
6. Adjust the wire stop of the balancer so that the torque arm cannot be fully
retracted.
7. Secure all the screws with the set screws (see Spare Parts).

Operation
Operating instructions
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.

Maintenance instructions
Daily maintenace
Do not operate the torque arm if it is damaged or malfunctioning.
• Examine the torque arm attachment and all structural parts for wear and
cracks.
• Examine the torque arm for loose screws and nuts.
• Do a complete functional test including a full extension and retraction of the
torque arm in its complete range of movements.
• Examine sliding bearings and axles when there is high friction.
• Replace the entire arm if extensive wear, cracks and/or damage are detected.
• Replace worn nuts or washers.
Lubrication instructions
Lubrication
• We recommend that the bench stand pole is lubricated with a couple of
drops of oil twice a year.
