The product warranty relies on the correct use, maintenance, and repair of the tool and its component parts.
Damage to parts that occurs as a result of inadequate maintenance or performed by parties other than Atlas Copco or their Certified Service Partners during the warranty period is not covered by the warranty.
To avoid damage or destruction of tool parts, service the tool according to the recommended maintenance schedules and follow the correct instructions.
Warranty repairs are performed only in Atlas Copco workshops or by Certified Service Partners.

Assembling the Anti-Overturning Bar
Assemble the anti-overturning bar below the cradle with four M4 screws.
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 vibration.
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 determine the amount of reaction force that an operator can tolerate. 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.
In dusty environments, use a dust extraction system or wear a mouth protection mask.
Operating Instructions
Operating the cradle

The STRwrench Smart Cradle is designed for a mains voltage/frequency range of 100V to 240V and 50Hz to 60Hz.
Connect the cradle to the mains power. When the cradle is connected to the mains supply, the power indicator glows green.
Smart Cradle is designed to charge only STRwrench Compact with S/N starting from Bxxxxx and STRwrench Advanced with S/N starting from Cxxxxxx.
Insert the STRwrench into the cradle. Charging starts automatically as soon as the STRwrench is placed. The charging time depends on the charge state of the STRwrench battery.
The Smart Cradle is not compatible with the following STRwrench smartHEAD models:
8059 0924 47 (600 Nm)
8059 0924 50 (1000 Nm CAR)
8059 0924 49 (1000 Nm ALU)
Interconnect Cradle
The cradle has a built-in interconnection function. The maximum number of interconnected cradles is limited, depending on the output voltage of the power supply.
Maximum 4 cradles at 100 V AC (Japan)
Maximum 5 cradles at 110-120 V AC
Maximum 10 cradles at 240 V AC
This includes the master cradle, that is connected to the alternating current (AC) grid.
Battery Charge Display

The battery charging is shown by the bars in the battery indicator. The battery level indicators keeps on blinking in sequence from lowest level to highest level till the battery is fully charged.
Level | Battery bar indicator | Light behavior | Battery status |
---|---|---|---|
1 | 3 white bars | Steady | Full charge |
2 | 1, 2, 3 white bars | Sequence | Charging |
