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.
Operating Instructions
Wi-Fi Zone Tethering
Not available for all models.
This tool features the Wi-Fi Zone Tethering (WZT) function, intended to make the tool less susceptible to
theft.
The functionality limits the usability of the tool when it exceeds a specific Wi-Fi network or tethering zone.
The tool has to be tethered to a network and can only be used for a limited time without being connected
to the network, before the tool is locked. When the tool is locked it cannot be used for drilling. The tool's
display will show the tool event.
When the tool is reconnected to the network again the tool is unlocked and fully operational again.
For more information to configure the Wi-Fi Tethering, see ToolsTalk Service 2 User Edition user guide.

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 environ-
ment. The figure below shows an example of an appropriate service work station.
Maintenance Instructions
Preventive Maintenance
Maximize Battery Life
In order to maximize battery life, do not leave the battery connected to the tool if you do not plan to use it
for several days. The battery can discharge and go into “sleep mode” which will require a special wake-up
charge procedure.
Overhaul
Have your power tool serviced by a qualified repair person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Service must only be carried out by qualified personnel who have access to the Service instruction and/or
have been trained for service on (these specific) EBB and EBP tools.
The electric motor is a sealed unit and may under no circumstances be opened by anyone else than Atlas
Copco Industrial Technique AB.
Overhaul and preventive maintenance is recommended at regular intervals once per year or after maxi-
mum 250.000 drilling cycles depending on which occurs sooner. More frequent overhaul may be needed if
the machine is used in heavy-duty operations. If the machine not is working properly, it should immedi-
ately be taken away for inspection.
When dismantling the tool always use the specially designed service tool 4080 0848 80, (two service
tools are required).
Lubrication Instructions
Lubrication
Lubricate gears with grease containing molybdenum disulphide (e.g. Molykote BR2 Plus). Lubricate o-
rings and threaded connections with grease (e.g. Almagard LE 3751) before assembling.
Brand Type
Molykote BR2 Plus
