CORDLESS NUTRUNNER
• Use Dual trigger to minimize the risk of fingers or hands
getting caught between the reaction bar and the work
piece.
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.
For corded tools: 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 discon-
necting the tool cable.
Special precaution
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 reaction bar, thus re-
sulting 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 work.
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
employer 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.
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.
For tools containing a clutch: Immediately after adjusting
the clutch, check for correct operation.
General Instructions
The tool may only be used together with the associated
torque reaction bar, which is adapted to the screw joint appli-
cation concerned.
WARNING Crushing Hazard
Check the rotational direction of the tool before start! A
start in an unexpected rotational direction can cause
bodily injury or property damage. Moving parts can
crush and cut.
Operating the tool
