Intended Use

This product is designed for installing and removing threaded
fasteners in wood, metal or plastic. Indoor use only.
No other use permitted.

Product Specific Instructions

Installation
General Installation Safety
Refer installation to qualified personnel only.
Hang the tool securely, by for example using a balancer.
When using a suspension yoke, check that it is in good con-
dition and correctly fastened.
Always connect the system to an earthed outlet. Always
make sure that the mains plug is disconnected and the con-
troller is turned off before connecting or disconnecting the
tool cable.
Operation
General Operation Safety
• Due to entanglement risk, do not wear gloves.
• Be prepared of the reaction force which will occur
when the tool is used. Always support the tool's handle
securely in the direction opposite to the spindle rotation,
in order to reduce the effect of sudden torque reaction
during final tightening and initial loosening.
• Never hold the drive, socket or drive extension.
• Operators and maintenance personnel must be physi-
cally able to handle the bulk, weight and power of the
tool.
• If possible, use a suspension arm to absorb the reac-
tion torque. If that is not possible, side handles are
recommended for straight-case and pistol-grip tools;
reaction bars are recommended for angle nutrun-
ners. It is recommended to use a means to absorb the re-
action torque above 4 Nm (3 lbf.ft) for straight-case
tools, above 10 Nm (7.5 lbf.ft) for pistol-grip tools, and
above 60 Nm (44 lbf.ft) for angle nutrunners.
• Serious injury can result from over-torqued or un-
der-torqued fasteners. Assemblies requiring a specific
torque must be checked using a torque meter. So-called
"click" torque wrenches do not check for potentially
dangerous over-torqued conditions. Over-torqued or un-
der-torqued fasteners can break, loosen or separate. Re-
leased assemblies can become projectiles.
• Use only power or impact sockets in good condition.
Do not use hand sockets.
• When using a power tool, the operator may feel dis-
comfort in the hands, arms, shoulders, neck, or other
parts of the body. Vary between appropriate postures
throughout the work day, maintain a secure footing and
avoid awkward or off-balance postures.
• Repetitive work motions, awkward positions and ex-
posure to vibration can be harmful to hands and
arms. If numbness, tingling, pain or whitening of the
skin occurs, stop using tool and consult a physician.

• Take caution when operating in confined spaces. Be-
ware of crushing hands between tool and workpiece.
• High sound levels can cause permanent hearing loss.
Use hearing protection as recommended by your em-
ployer or occupational health and safety regulations.
• Ensure that the workpiece is securely fixed.
• Proceed with care in unfamiliar surroundings. Be
aware of potential hazards created by your work activity.
This tool is not insulated from coming into contact with
electric power sources.
• Avoid using tightening strategies in applications outside
their limitations.
• Major changes in joint characteristics will affect the op-
erator reaction force.
• Consider that a joint failure or a tool error can cause sud-
den unexpected reaction force and possibly injure the op-
erator.
• Position the equipment so that the disconnecting device
is within easy reach.
Tools used together with a reaction bar: Never put your
hand near or close to the reaction bar while the tool is being
used. Be aware of the rotational direction of the spindle be-
fore starting the tool, the reaction force may work in an unex-
pected direction with risk of crushing injuries.
Tools containing a clutch: Never use the product without
making sure the clutch releases. Immediately after adjusting
the clutch, check for correct operation.
WARNING Risk of Injury
Make sure that the correct parameter file is being used.
Wrong parameter file might cause too high torque with
bodily injury as a result.
Compare the maximum torque which is shown in
►
the controller, with the maximum torque stated in
the technical data of the tool, they should be the
same.
Service and Maintenance
General Service and Maintenance Safety
Always keep the controller switched off during service in or-
der to avoid unexpected start-up.
The product must only be installed, operated and serviced by
qualified personnel in an industrial environment.
Cleaning Instruction
Equipment should be wiped off with a damp/wetted cloth.
Only use water, no cleaners containing solvents should be
used.
Contact your Atlas Copco service technician for cleaning ad-
vice as per current recommendations and for your particular
tool.
Regular Cable Inspections
Regularly inspect the power cable and the tool cable. If the
cables show any sign of damage, replace them.
