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:

Product information EN BCP BL-12-I06

■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 a maxi-
mum of 250.000 tightenings. More frequent overhaul may be needed if the tool is used at high torque or
with long tightening times. Take out the tool for inspection if it is not working correctly.
At overhaul, clean all parts accurately and replace defective or worn parts.
Lubricate gears and clutch with grease containing molybdenum disulphide, for example Molykote BR2
Plus, refer to the exploded views.
Lubricate o-rings and threaded connections with grease before assembling.
Make sure that all threaded connections on the tool are tightened correctly according to the specifications
on the exploded views.

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
Setting the tightening torque
For a safe and accurate operation, set the tightening torque of the screwdriver in relation to the screw
joint.

Adjusting the torque
The tightening torque is adjusted by changing the tension of the clutch spring with the key and the adjust-
ment disc (clutch adjusting kit).
Start at a low torque setting to prevent screw joint damage. If the torque is set too high, there will be no
click-sound from the clutch, the green LED will not lit and the motor will be turned off.
Do not adjust the torque over the recommended maximum value as it will result in incorrect function
and faster wear.
1. Put the key in the hole at the front part of the tool.
2. Turn the key clockwise to increase the tightening torque.
3. Finish the adjustment at a holding position, located each 1.5 turns of the key.

tached pointing forward or backward to get the best accessibility and balance. To remove the battery
pack, push 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.

Charging the battery pack
Use only an Atlas Copco battery charger (see optional accessories). Refer to the separate instruc-
tions delivered with the charger.
Fully charge a new or a long time unused battery pack before using your battery tool. Full loading capacity
of a battery pack is reached after 4-5 charges.
Keep battery and charger contacts clean.
It the tool will not be used for 100 hours or longer, remove the battery pack from the tool. Otherwise the
electronics will discharge the battery.
Standby behaviour (to serial no.A3482444)
To save battery power the tool will switch automatically to a standby mode when it is not used. All LEDs
are off in standby mode.
Push the trigger to wake up the tool. The tool starts immediately and runs in a clockwise direction even if it
is set to counterclockwise.
Push the trigger a second time to run the tool in the set direction.
Standby behaviour (from serial no.A3482445)
To save battery power the tool will switch automatically to a standby mode when it is not used. All LEDs
are off in standby mode.
Push the trigger to wake up the tool. Push the trigger a second time to run the tool.
Make sure that the tool is set to the wanted direction.

Service
Preventing ESD problems
The components inside the tool and controller are sensitive to electrostatic discharge. To avoid future mal-
function, 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:

■Replace any defective or worn parts
Service instructions
Overhaul and preventive maintenance is recommended at regular intervals once per year or after a maxi-
mum of 250.000 tightenings. More frequent overhaul may be needed if the tool is used at high torque or
with long tightening times. Take out the tool for inspection if it is not working correctly.

Preventive maintenance
Maximize battery life
In order to maximize battery life, do not leave the battery connected to the tool you do not use it for sev-
eral days. The battery can discharge and go into “sleep mode” which will require a special wake-up charge
procedure. For further information, see instructions for multicharger, 4211542485.

Troubleshooting
Error codes
LED
Indications
3 red flashes followed by 2 yellow flashes
Clutch sensor error. The tool does not start or stops correctly.
The signal given by the clutch sensor is out of tolerances. Do a check of the sensor and the
magnets for the sensor. Make sure that the flex is connected correctly to the electronic board.
If the fault still appears, contact customer service.
3 red flashes followed by 3 yellow flashes
The temperature is over the maximum limit of 70°C. The tool does not start or stops correctly.
The temperature measured with the electronic board is higher than 70°C. Wait for the tool to
cool down. When the temperature is lower than 70°C it is possible to operate the tool again.
Decrease the tool rate. If the temperature is lower than 70°C and the fault still appears, con-
tact customer service
3 red flashes followed by 4 yellow flashes
Overheated tool. Too high current over too long time. The tool does not start or stops cor-
rectly.
The power requested is too big. If the fault still appears, contact customer service.
3 red flashes followed by 5 yellow flashes
Battery voltage fault. The tool does not start or stops correctly.
The battery voltage is not correct for the tool. Make sure that the correct battery is used. If the
battery used is correct and the fault still appears, contact customer service.
3 red flashes followed by 6 yellow flashes
Overcurrent on the power circuit. The hardware limit is reached. The tool does not start or
stops correctly.
If the fault still appears, the power stage is faulty, contact customer service
