Overview

General Description

Powered by a new battery generation from Atlas Copco, Tensor SRB Cordless Nutrunner delivers one-handed operation with accuracy, traceability and flexibility. The SRB reports wirelessly to the Power Focus 6000 system and takes full advantage of Virtual Stations, able to perform low reaction strategies as a Turbo Tight and Tensor Pulse, and traditional strategies as the two steps. The Tensor SRB is ideal for low toque application where the reaction force hits the operator wrist. It is light weight and has a great balance – ergonomically designed to prevent operator fatigue.

Features

  • Slim design

  • All kind of strategies: Traditional and Low Reaction

  • One handed cable free

  • Operator feedback and battery status via LED indicator

  • A buffer battery makes battery swaps trouble free

  • Integrated indicator on the battery shows battery and health status

  • Dual antenna

  • Rapid Backup Unit (RBU) functionality

Benefits

  • High productivity and accuracy

  • Fast tightening

  • Full traceability

  • Short tightening cycle

  • Easy to set up

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

Installation

Installation Instructions

Attaching and Removing the Battery

  1. Attach the battery to the tool and make sure that it is fastened correctly. The battery can be attached pointing forward or backward to get the best accessibility and balance.

  2. To remove the battery, press the button on the battery and push it out.

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.

Operating Instructions

Tightening

As tightening torque increase the reaction force build up equally. Make sure that the tool is in correct working order and that the controller is correctly programmed. By doing this you avoid unexpected behavior from the tool, which may result in operator injury.

Rotation Direction for the Tightening

Check that the tool is in the correct running direction by turning the reverse button or reverse ring :

Pistol Grip Models (with side buttons)

  • Press in the reverse switch on the right hand side of the tool, to set the direction clockwise (CW).

  • Press in the reverse switch on the left hand side of the tool, to set the direction counter clockwise (CCW).

Pistol Grip Models (without side buttons)

  • Double press the function button on the top of the start trigger to shift the direction between clockwise (CW) and counter clockwise (CCW).

Angle Models

  • Turn the reverse ring to the right, to set the direction clockwise (CW).

  • Turn the reverse ring to the left, to set the direction counter clockwise (CCW).

Soft Start

The soft start function facilitates the screwhead and thread to reach the snug level. The duration of the soft start is adjustable.

For further information about tightening, see Power Focus 6000 Configuration manual.

General instructions

The tool may only be used together with the associated torque reaction bar, which is adapted to the screw joint application concerned.

  1. Attach the reaction bar to the tool and insert the retaining ring into the groove to hold the reaction bar in position.

  2. Attach the socket to the square drive. Insert the locking pin through the socket and square drive according to the illustration.

WARNING

Crushing Hazard

Check the rotational direction of the tool before start! A start in an unexpected rotational direction can cause bodily injury or property damage. Moving parts can crush and cut.

  • Make sure that the rotational direction of the tool is correct before starting the tool.

  • Keep hands and fingers away from moving parts.

Special precaution

WARNING

Crushing Hazard

The Dual trigger forces the user to use both hands to operate the tool. If not used, the operator can accidentally start the tool while adjusting the reaction bar, thus resulting in a serious hand injury.

  • Make sure the tool cannot be started once the Dual trigger has been released.

  • Always test the tool by first releasing the trigger of the Dual trigger, then push the trigger of the tool. If the tool starts; stop work.

Service

Preventing ESD Problems

The components inside the product and controller are sensitive to electrostatic discharge. To avoid future malfunction, make sure that service and maintenance is carried out in an ESD approved work environment. The figure below shows an example of an appropriate service work station.

Maintenance Instructions

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

Service instructions

Overhaul and preventive maintenance is recommended at regular intervals once per year or after maximum 250.000 tightening depending on which occurs sooner. More frequent overhaul may be needed if used at high torque, high cycle rate or long tightening times. If the machine is not working properly, it should immediately be taken away for inspection.

At the overhauls, all parts should be cleaned accurately and defective or worn parts (i.e. O-rings) should be replaced.
