Product Specific Instructions
Special precautions for STR and ETT tools
WARNING Risk of injury
Major changes in joint characteristics will affect the op-
erator reaction force and can injure the operator.
Avoid using tightening strategies in applications out-
►
side their limitations.
Recommended value for Rundown Complete is 10%
►
of target torque.

Hang the tool securely, by for example using a balancer.
When using a suspension yoke, check that it is in good condi-
tion and correctly fastened.
Always connect the system to an earthed outlet. Always make
sure that the mains plug is disconnected and the controller is
turned off before connecting or disconnecting the tool cable.
Operation
Special Precautions for Open End Nutrunners
WARNING Crushing Hazard
Never reach into the open-end head. Moving parts can
crush and cut. Keep hands and fingers away from mov-
ing parts.
Dual Trigger
Dual trigger (Recommended to use during
operation)
WARNING Crushing Hazard
The Dual trigger forces the user to use both hands to op-
erate the tool. If not used, the operator can accidentally
start the tool while adjusting the crowfoot, 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 working.
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 nutrunners.
It is recommended to use a means to absorb the reaction
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 under-
torqued fasteners. Assemblies requiring a specific
torque must be checked using a torque meter. So-called
"click" torque wrenches do not check for potentially dan-
