Installation Instructions
Battery Pack
Attaching and Removing the Battery Pack
1. Attach the battery pack to the tool and make sure that it is fastened correctly. The battery pack can
be attached pointing forward or backward to get the best accessibility and balance.
2. To remove the battery pack, press the button on the battery and push it out.
Since a battery pack slowly discharge itself, keep the battery pack in the charging unit that provides a
trickle charge.

Operation
Ergonomic guidelines
Consider your workstation as you read through this list of general ergonomic guidelines and see if you can
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 convenient reach range by determining where parts or tools should 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 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 requiring a degree of force.
■Adjust for convenient field of vision by minimizing movement of the eyes and head during the work
task.
■Use the appropriate lighting for the work task.
■Select the appropriate tool for the work task.
■Use ear protection equipment in noisy environments.
■Use high-quality inserted tools or 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 wheel is either bent or if it is not guided properly. Make sure to
use the correct flanges for cut-off wheels and avoid bending the wheel during cut-off operation.
■When drilling:
The drill might stall when the drill bit breaks through. Makes sure you use support handles if the
stall torque is too high. The safety standard ISO11148 part 3 recommends using something to ab-
sorb the reaction torque above 10 Nm for pistol grip tools and 4 Nm for straight tools.
■When using direct-driven screw or nutrunners:
Reaction forces depend on tool setting and joint characteristics. The ability to bear reaction forces
depends on the operator’s strength and posture. 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.
■Use dust extraction system or mouth protection mask in dusty environments.
Operating Instructions
Tightening
As tightening torque increase the reaction force build up equally. Make sure that the tool is in correct work-
ing 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).

Operation EN ETP SRB81-3400-25-HA-D
8© Atlas Copco Industrial Technique AB - 9839 1652 01
■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.
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.
