Safety Information
• Disconnect the plug from the power source and/or the
battery pack from the power tool before making any
adjustments, changing accessories, or storing power
tools. Such preventive safety measures reduce the risk of
starting the power tool accidentally.
• Store idle power tools out of the reach of children and
do not allow persons unfamiliar with the power tool
or these instructions to operate the power tool. Power
tools are dangerous in the hands of untrained users.
• Maintain power tools. Check for misalignment or
binding of moving parts, breakage of parts and any
other condition that may affect the power tool's oper-
ation. If damaged, have the power tool repaired be-
fore use. Many accidents are caused by poorly main-
tained power tools.
• Keep cutting tools sharp and clean. Properly main-
tained cutting tools with sharp cutting edges are less
likely to bind and are easier to control.
• Use the power tool, accessories and tool bits etc. in ac-
cordance with these instructions, taking into account
the working conditions and the work to be per-
formed. Use of the power tool for operations different
from those intended could result in a hazardous situation.
• Keep handles and grasping surfaces dry, clean and
free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the
tool in unexpected situations.
Additional Safety Rules for screwdrivers and
wrenches
Entanglement hazards
• Keep away from rotating drive. Choking, scalping
and / or lacerations can occur if loose clothing, gloves,
jewellery, neck ware and hair are not kept away from
tool and accessories.
• Do not wear loose-fitting gloves or gloves with cut or
frayed fingers. Gloves can become entangled with the
rotating drive, causing severed or broken fingers.
• Rotating drive sockets and drive extensions can easily
entangle rubber-coated or metal-reinforced gloves.
• Never hold the drive, socket or drive extension.
Operating hazards
• Operators and maintenance personnel must be physi-
cally able to handle the bulk, weight and power of the
tool.
• Hold the tool correctly: be ready to counteract nor-
mal or sudden movements. Have both hands available.
• Immediately after adjusting the clutch, check for cor-
rect operation.
• Do not use in a worn condition. The clutch may not op-
erate, resulting in sudden rotation of the tool handle.
• Always support the tool's handle securely, in the di-
rection opposite to the spindle rotation, to reduce the
effect of sudden torque reaction during final tighten-
ing and initial loosening.

• 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. In any case, 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 nutrun-
ners.
Projectile hazards
• Always wear impact-resistant eye and face protection
when involved with or near the operation, repair or
maintenance of the tool or changing accessories on
the tool.
• Be sure all others in the area are wearing impact-re-
sistant eye and face protection. Even small projectiles
can injure eyes and cause blindness.
• 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. Serious injury can result from over-
torqued or under-torqued fasteners, which can break, or
loosen and separate. Released assemblies can become
projectiles.
• Do not use hand sockets. Use only power or impact
sockets in good condition.
• This tool and its accessories must not be modified in
any way.
Repetitive motion hazards
• When using a power tool to perform work-related ac-
tivities, the operator might experience discomfort in
the hands, arms, shoulders, neck, or other parts of
the body.
• Adopt a comfortable posture whilst maintaining se-
cure footing and avoiding awkward or off-balance
postures. Changing posture during extended tasks can
help avoid discomfort and fatigue.
• Do not ignore symptoms such as persistent or recur-
ring discomfort, pain, throbbing, aching, tingling,
numbness, burning sensation, or stiffness. Stop using
the tool, tell your employer and consult a physician.
Workplace hazards
• Slip/Trip/Fall is a major cause of serious injury or
death. Cluttered areas and benches invite injuries.
• Do not use in confined spaces. Beware of crushing
hands between tool and workpiece, especially when un-
screwing.
• 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.
• 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.
