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 guide-
lines:
■Clean appropriate parts accurately
■Replace any defective or worn parts

ETP SRB 31-20-10 EN Installation

Installation
Installation Requirements
Installation
For installation guideline, see Power Focus 6000 Configuration manual.
Installation Instructions
Torque Adjustment
For installation of the torque adjustment, see Power Focus 6000 Configuration manual.
The torque adjustment factor is stored in non-volatile memory in the tool. Any changes made to the
torque adjustment factor in the POWER FOCUS 6000 will update the stored value in the tool.
Rapid Backup Unit
The Rapid Backup Unit (RBU) has the form factor of an SD card. The RBU contains all the current net-
work configurations and settings. During the installation and configuration some of the parameters are
saved on the card. In case of a failure, it is a quick task to remove the card and put it into a new tool and
all functionality remains the same.
When the RBU is transferred from one tool to another, the new tool will be updated to the software on
the card. Since there is a chance of loss of data during the update procedure, it is good practice to
make sure the new tool is already running the same software version as the old tool, to minimize the
risk of data loss.
This RBU can not be used for anything but storing the tool configuration data and software. Reformat-
ting the card, as well as manipulating the data on the card through other means than ToolsTalk Ser-
vice 2, will result in an unusable card.
Note that the saved results associated with the tool will be lost when the RBU is transferred to an-
other tool.
The MAC-address is associated with the RBU, not with the tool itself. When transferring a card to a
new tool, the tool's MAC-address will therefore be the RBU's MAC-address.
Tool Conversion
When converting a tool (for example, by changing the front part), you are required to update the tool infor-
mation in order to reflect the changes made to the tool. For more information see ToolsTalk Service 2
User Edition user guide
WARNING Risk of injury
Tool modifications, when not done properly, can cause bodily injury, damage to the tool, or produce
undesired results, due to the altered characteristics of the tool.
►Check the tool's max torque after modification
When connected to ToolsTalk Service 2 you will not be prompted to change the tool information. To
change the tool designation to match the tool conversion, perform the same steps as those for spare part
replacements. Use the tool designation of the new part to update the tool.
Since the tool has been converted, the tool information stored on the tool will no longer match the tool
designation on the tool sign.

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 vibra-
tion.
■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 deter-
mine the amount of reaction force that an operator can tolerate. Adapt the torque setting to the op-
erator'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
Tightening Programs
Assigning tightening programs and altering tightening program parameters is done through the controller
the tool is paired with.
For more information, see Power Focus 6000 Configuration manual.
Operating Instructions
LED Indicator Flash Patterns
Apart from the LED flash patterns determined by the controller, there are a number of standard flash pat-
terns for the tool LED indicators.
