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, compo-
nent 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 as-
sembly operations.
• When working above shoulder level, reduce the load on the static mus-
cles 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 requir-
ing 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 ex-
cessive 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 absorb 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 abil-
ity to bear reaction forces depends on the operator’s strength and pos-
ture. 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.

Testing of tightening torque
Torque and angle testing instrument
Testjoint and Transducer
Select testjoint and transducers according to minimum and maximum torque of
your tool
Tightening torque
For accurate operation and safety, the tightening torque of the screwdriver must
be adjuisted correctly in relation to the screw joint. Check the torque specifica-
tion for the actual joint.
The tightening torque is adjusted by altering the tension of the clutch spring.
Turn the protection ring until the hole in the clutch housing is free. Then turn
the out going spindle until you can see the keyhole in the adjustment washer.
Turn the adjustment key clockwise to decrease and anticlockwise to increase
the torque. After the adjustment, turn the protective ring back again.
Verification of tightening torque
Recommended equipment for verification if tightening torque are an Atlas
Copco Torque Analyser plus an appropriately-sized transducer together with
the available test joints.
Torque range of the clutch springs
Each clutch spring gives a certain torque range. Do not adjust the torque
over the maximum recommendation as that might result in improper func-
tion and faster wear of the clutch.
