# Operating Instructions

# 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. Always 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.

# Turning On the Wrench

1. On the back of the MTRwrench 85 HMI, pull back the locking lever on the battery housing's door and open the door.

2. Insert the battery into its housing.

   Make sure that the lace edge is visible to make removal easier.

3. Close the battery housing door.

   Make sure that the edge of the lace remains inside.

Once the MTRwrench 85 is on, the Progress LEDs on the HMI start blinking with white light show that a MTRwrench 85 requires a zerozero adjustment is required.

The Radio Communication LED on the HMI starts blinking to notify the MTRwrench 85 wireless communication is ON.

- Zero Adjustment LED Indicators

# Handling the Wrench

Correct handling:

- Tighten in even strokes.

- Hold the MTRwrench 85 by the middle of the handle when performing a tightening.

- Apply force only in the tightening direction.

- The force applied to the wrench must be one-handed, uniform, parallel and continue until the tool clicks.

- Keep a tightening speed that enables you to immediately stop tightening as soon as the MTRwrench 85 clicks.

Wrong handling:

- Do not apply any force to the wrench after the automatic release (click).

- Do not apply force to the wrench in any direction other than the tightening direction.

- Do not touch the body of the MTRwrench 85 during tightening operations. Positioning the thumb on the tube alters the click value!

- Do not hold the battery housing of the MTRwrench 85 during tightening operations.

# Running Tightening Operations

1. Connect the MTRwrench 85 to the Power Focus 6000/Power Focus 8 via MWR-KIT.
