# Safety Signal Words

The safety signal words Danger, Warning, Caution, and Notice have the following meanings:

DANGER | DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING | WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION | CAUTION, used with the safety alert symbol, indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
NOTICE | NOTICE is used to address practices not related to personal injury.

# Warranty

- Product warranty will expire 12 months after the product is first taken into use, but will in any case expire at the latest 13 months after delivery.

- Normal wear and tear on parts is not included within the warranty.

  - Normal wear and tear is that which requires a part change or other adjustment/overhaul during standard tools maintenance typical for that period (expressed in time, operation hours or otherwise).

- The product warranty relies on the correct use, maintenance, and repair of the tool and its component parts.

- Damage to parts that occurs as a result of inadequate maintenance or performed by parties other than Atlas Copco or their Certified Service Partners during the warranty period is not covered by the warranty.

- To avoid damage or destruction of tool parts, service the tool according to the recommended maintenance schedules and follow the correct instructions.

- Warranty repairs are only performed in Atlas Copco workshops or by Certified Service Partners.

Atlas Copco offers extended warranty and state of the art preventive maintenance through its ToolCover contracts. For further information contact your local Service representative.

For electrical motors:

- Warranty will only apply when the electric motor has not been opened.

# Overview

# Applications

The MicroTorque screw fastening systems are ultra low-torque applications.

# Bit run out test

Bit run out is measured with the tool securely fastened in a test rig and with the tool running at no load with a rotation speed of 200 rpm. Measuring point is at 44 mm (length of a standard bit) out on a special bit 4216 2194 00. Bit run out limit is 0.15 mm.

# Bit grounding test

Bit grounding is measured by the ground circuit stability and resistance with the tool running at no load with a rotation speed of 200 rpm. Resistance is measured between the special bit 4216 2194 00 and the outside of the tool connector and the resistance limit is 20 Ω.

# Service Overview

# Service Recommendations

Preventive maintenance is recommended at regular intervals. See the detailed information on preventive maintenance. If the product is not working properly, take it out of service and inspect it.

If no detailed information about preventive maintenance is included, follow these general guidelines:

- Clean appropriate parts accurately

- Replace any defective or worn parts

# Preventive maintenance

Service should only be carried out by trained technician following provided service instructions and using original Atlas Copco spare parts.

The preventive maintenance intervals are based on the following definitions of use:

- Tools are tested at their maximum torque. Operating at a lower target torque results in longer service intervals and reduced maintenance frequency.

- The application is to assemble machine screws into metal threads. The typical run-down torque is below 15% of the target torque. Thread cutting or thread forming applications with high prevailing torque will reduce the service interval of the motor.

- The tightening angle ranges from 30° (hard joint) to 720° (soft joint). The tightening angle is measured between seating and target torque. A higher tightening angle will reduce the service interval of the motor.

- The highest possible speed for each torque level and joint characteristic is recommended. Lower speeds at high torque will reduce the service interval of the motor.

- The feed force is limited by the axial load limitations of the ball bearings to a maximum of 80 N. A low feed force ensures good tightening accuracy and increases the service interval for the front part. High load and/or high-speed impacts to the front part can damage the ball bearings.

- The vacuum pickup system will increase wear on the rubber sealings of the ball bearings, reducing the service interval for the front parts.

- Tightening problems such as overshooting, stuck bits, and bit slip can reduce the service interval of the tool. These problems can be minimized by proper programming, using limits, and dividing the programming into several steps with different limits.

  For more information about tightening strategies and troubleshooting, please refer to the configuration manual for ToolsTalk MT.

# Installation

# Installation Instructions

# Installing the tool

- Connect the tool to the drive using the supplied cable.

- If required, hang the tool securely, for example from a balancer.

The tool can also be fixtured using the threds at the front part, accessible under the thread protection ring.

NOTICE

Make sure the cable is not bent more than a radious of 55 mm (2.2 in).

# 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.
