Mechanical installation of controller
The controller can be used in three ways:
• Standing on a work bench.
• Attached to a vertical surface using the wall bracket.
• Attached to a vertical surface using screws from the rear side.
Wall bracket attachment
1. Attach the bracket to the surface using four 5 mm screws.
2. Pull out the plunger of the underside of the bracket and slide the controller
into the bracket.
3. The controller is held in placed by the plunger when released.
Rear screw attachment
1. Remove the two crews holding the controller foot.
2. Drill two 5 mm holes in the surface, corresponding to the holes in the con-
troller rear side. Leave space over the holes for the connectors and the
sound opening.
3. Attach the controller to the surface, preferrably with the removed screws.
NOTICE
• The screws must not protrude into the controller more than 10 mm.

Operation
Ergonomics
Ergonomic guidelines
1. Take frequent breaks and change work positions frequently.
2. Adapt the workstation area to your needs and the work task.
• Adjust for convenient reach range by determining where parts or tools
should be located to avoid static motion.
• Use workstation equipment such as tables and chairs appropriate for the
work task.
3. Avoid work positions above shoulder level or with static holding during as-
sembly operations.
• When working above shoulder level, reduce the load on the static mus-
cles by reducing 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.
• Make sure to take frequent breaks.
• Avoid extreme arm or wrist postures, particularly for operations requir-
ing a degree of force.
4. Adjust for convenient field of vision by minimizing movement of the eyes
and head during the work task.
5. Use the appropriate lighting for the work task.
Configuration
Please refer to User guide 9836 5637 01: ToolsTalk MT.

Service
Maintenance
Preventing ESD problems
The components inside the tool and controller are sensitive to electrostatic dis-
charge. 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.
Service recommendations
Overhaul and preventive maintenance is recommended at regular intervals. See
the Preventive maintenance section for detailed information regarding over-
haul of your tool and specific parts. 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 should be replaced.
Maintenance
There are certain general maintenance procedures you should perform to keep
your MicroTorque system clean and operating at its efficiency.
The system is a sophisticated instrument with many sensitive components.
A built-in service reminder can be configured in Tools Talk MT. When it is
time to perform service on the tool, a reminder is shown on the controller dis-
play.
Preventive Maintenance:
• The system should never be exposed to harsh environment with rapid tem-
perature changes or excessive dust.
• Never expose the system to excessive vibration or high humidity.
• Prevent overheating by use only in the permitted temperature range. Do not
cover tool or controller or power supply.
• Cleaning of the tool and controller should be done regularly, but not with
aggressive cleanser.
• Check wear of the bit regularly.
• Replace worn cables immediately.
Tools which have been opened by anyone else than Atlas Copco Industrial
Technique AB, will not be serviced.
Calibration and preventive maintenance is recommended at regular intervals
once per year or after maximum 1.000.000 tightenings depending on which oc-
curs sooner.

Service EN MT Focus 400
