# Installation

# Installation Requirements

# Overheating

Operating at high torque on soft joints with short cycle time can cause overheating and shorten the life of the tool. Contact your local Atlas Copco sales representative if you need help with simulations or calculations before selecting model and size of the tool. Please provide the following information for a heat calculation:

- Target torque (Nm) - Speed during the rundown and during the tightening (RPM).

- Rundown angle in revolutions or degrees.

- Tightening angle in degrees.

- Cycle time - Seconds between the start of each tightening, or tightenings per hour.

# Compression Spring

If several compression springs are delivered with the tool, the strongest spring is installed in the front part of the tool. Any additional springs are delivered unassembled.

# Side Force

Side force can occur if:

- A multiple, with two or more fixtured tools, is not fixed relative to the assembly object.

- A single tool is used with a reaction bar to handle the reaction torque.

If the tool(s) and the assembly object are locked in their respective fixtures, there will be no or low force.

If the socket holder of the tool is exposed to side force, make sure that all ingoing parts can handle the side force. Contact your local Atlas Copco customer center if you need help confirming that all components can handle the side force.

# Clamping

No clamping is allowed on the transducer, the gear unit or the motor unit. Use only the designated holes for clamping, marked on the dimensional drawing.

# Motor connector

The motor connector is rotatable ± 150 degrees along two axes.
