# Installation

# Installation Instructions

# Connecting to STRwrench QA Inspector Software Web User Interface

1. Switch on the wrench and open the USB-C port cover.

   Do not remove the cover of the USB-C port completely.

2. Connect the tool to the USB port of the PC. Open a web browser and type in the address of the STRwrench QA Inspectore Software Web User Interface: `169.254.1.1`.

# Attaching the Battery

1. Unscrew the battery cap placed at the end of the wrench handle.

2. Insert the battery into the wrench handle by aligning it with the nut inside until the mechanic stops.

3. Screw the battery cap on the wrench handle.

# Removing the Battery

1. Unscrew the battery cap placed at the end of the wrench handle.

2. Pull the battery out of the wrench handle.

3. Screw the battery cap on the wrench handle.

# Attaching the End-Fitting Tool

1. Insert the End-Fitting Tool by aligning the PIN with the reference guide inside the smartHEAD.

2. Push the End-Fitting Tool until the mechanic stops and the PIN is locked.

There is only one way to insert the End-Fitting Tool into the smartHEAD. The PIN must be inserted into its housing: do not force it in other positions.

# Removing the End-Fitting Tool

1. Push the PIN on the smartHEAD to unlock it from its housing.

2. Remove the End-Fitting Tool from the smartHEAD.

# Attaching the smartHEAD

1. Attach the smartHEAD to the wrench controller.

   To optimize the vision of the EHMI during operations in special circumstances, the smartHEAD can be attached in 4 positions, each at 90° rotation.

2. Pull down the ferrule.

3. Rotate the ferrule clockwise while pushing it down to fasten the smartHEAD to the wrench controller.

# Removing the smartHEAD

1. Rotate the smartHEAD's ferrule counterclockwise while pushing it down to unlock the smartHEAD from the wrench controller.

2. Pull up the ferrule.

3. Remove the smartHEAD from the wrench controller.

# Initial Configuration

# Tool Configuration

For information about establishing a wireless connection, installing licenses, configuring and running inspections, refer to STRwrench QA Inspector Software User Guide.

# Firmware Installation and Upgrade

For information about firmware installation and upgrade, refer to STRwrench QA Inspector Software User Guide.

# Operation

# Ergonomic Guidelines

Consider your workstation as you read through this list of general ergonomic guidelines to identify areas for improvement in posture, component placement, or work environment.

- Take frequent breaks and change work positions frequently.

- Adapt the workstation area to your needs and the work task.

  - Adjust for a convenient reach range by determining where parts and tools need to be located to avoid static load.

  - Use workstation equipment such as tables and chairs appropriate for the work task.

- Avoid work positions above shoulder level or with static holding during assembly operations.

  - When working above shoulder level, reduce the load on the static muscles by lowering the weight of the tool, using for example torque arms, hose reels or weight balancers. You can also reduce the load on the static muscles by holding the tool close to the body.

  - Take frequent breaks.

  - Avoid extreme arm or wrist postures, particularly during operations requiring a degree of force.

- Adjust for a convenient field of vision that requires minimal eye and head movements.

- Use appropriate lighting for the work task.

- Select the appropriate tool for the work task.

- In noisy environments, use ear protection equipment.

- Use high-quality inserted tools and consumables to minimize exposure to excessive levels of vibration.

- Minimize exposure to reaction forces.

  - When cutting:

    A cut-off wheel can get stuck if the cut-off wheel is bent or not guided properly. Use the correct flange for the cut-off wheel and avoid bending the cut-off wheel during operation.

  - When drilling:

    The drill might stall when the drill bit breaks through. Use support handles if the stall torque is high. The safety standard ISO11148 part 3 recommends using a device to absorb a reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.

  - When using direct-driven screwdrivers or nutrunners:

    Reaction forces depend on the tool settings and joint characteristics. Strength and posture determine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the operator's strength and posture and use a torque arm or reaction bar if the torque is too high.

- In dusty environments, use a dust extraction system or wear a mouth protection mask.

# Configuration Instructions

# Vibration

This tool is equipped with a vibrating device, which can be configured to signal specific events or warnings.
For more information on the vibration functionality and configuration, refer to STRwrench QA Inspector Software User Guide.

# Buzzer

This tool is equipped with a buzzer, which can be configured to signal specific events or warnings.
For more information on the buzzer functionality and configuration, refer to STRwrench QA Inspector Software User Guide.

# smartHEAD Illuminating Light

The smartHEAD illuminating light provides illumination under the end fitting tool; it can be helpful for a better view of joints in dark areas. It is activated for 10 seconds when the barcode button on the wrench EHMI is pressed.

For more information on the light functionality and configuration, refer to STRwrench QA Inspector Software User Guide.

# Operating Instructions

# Smart Zeroing

An automatic zero adjustment occurs every time the STRwrench is powered on and every time a smartHEAD is connected to the STRwrench controller.

During the zero adjustment, the wrench must lay steady without applying any torque constraint.
If the STRwrench detects any movement during the procedure, the zero adjustment will start over again.

# Automatic Shutdown on Empty Battery

When the battery charge level dips below the critical threshold (12%), the STRwrench is configured to automatically shutdown. As soon as the critical level is reached, the tool starts emitting an intermittent acoustic notification and turns off after 5 minutes.

When the battery charge level is below 12%, it is not possible to perform tightening. When trying to perform tightenings with this charge level, a notification is displayed reminding of the inability to operate.

# Charging the battery

The STRwrench battery has to be charged by means of the STRwrench charger (Article nr. 8059 0924 10).

# Battery charge LED indicators

The wrench is powered by a Lithium-ion battery.

The LED indicators on the battery indicate the State of Charge (SOC) of the battery. To activate the LEDs, press the button placed on the battery.

1 | LED indicators | 2 | Button

The LEDs indicate the remaining capacity of the battery as follows:

Battery charge indicator | Remark
--- | ---
1 LED | Critical level, not possible to perform tightening. Charge battery.
2 LEDs | Low charge. Charge battery.
3 LEDs | Medium charge. Charge battery, when possible.
4 LEDs | High charge.
5 LEDs | Full charge.

# LED indicators Flash Patterns

The standard flash patterns of the LED indicators are shown below:

General description | Light pattern description | Light color | Illustration*
