• If the rated speed, operating pressure or hazard warning
signs on the tool cease to be legible or become detached,
replace without delay.
For additional safety information consult:
• Other documents and information packed with this
tool.
• Your employer, union and / or trade association.
• "Safety Code for Portable Air Tools" (ANSI
B186.1), available at the time of printing from

Air supply and connection hazards
• Air under pressure can cause severe injury.
• Always shut off air supply, drain hose of air pressure and
disconnect tool from air supply when not in use, before
changing accessories or when making repairs.
• Never direct air at yourself or anyone else.
• Whipping hoses can cause severe injury. Always check
for damaged or loose hoses and fittings.
• Do not use quick disconnect couplings at tool. See in-
structions for correct set up.
• Whenever universal twist couplings are used, lock pins
must be installed.
• Do not exceed maximum air pressure of 6.3 bar / 90
psig, or as stated on tool nameplate.
Entanglement hazards
• Keep away from rotating drive. Choking, scalping and /
or lacerations can occur if loose clothing, gloves, jew-
ellery, neck ware and hair are not kept away from tool
and accessories.
• 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.
• Do not wear loose-fitting gloves or gloves with cut or
frayed fingers.
• Never hold the drive, socket or drive extension.
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-resis-
tant eye and face protection. Even small projectiles can
injure eyes and cause blindness.

• Serious injury can result from over-torqued or under-
torqued fasteners, which can break, or loosen and sepa-
rate. Released assemblies can become projectiles. As-
semblies requiring a specific torque must be checked us-
ing a torque meter.
NOTE So-called "click" torque wrenches do not check
for potentially dangerous over-torqued conditions.
• Do not use hand sockets. Use only power or impact
sockets in good condition.
• Ensure that the workpiece is securely fixed.
Operating hazards
• Disconnect the air supply before handling the screw-
driver bit or socket, adjusting the clutch or dismantling
the tool.
• Operators and maintenance personnel must be physically
able to handle the bulk, weight and power of the tool.
• Hold the tool correctly: be ready to counteract normal or
sudden movements – have both hands available.
• Immediately after adjusting the clutch, check for correct
operation.
• Do not use with reduced air pressure or in a worn condi-
tion: the clutch may not operate, resulting in sudden rota-
tion of the tool handle.
• Always support the tool's handle securely, in the direc-
tion opposite to the spindle rotation, to reduce the effect
of sudden torque reaction during final tightening and ini-
tial loosening.
• If possible, use a suspension arm to absorb the reaction
torque. If that is not possible, side handles are recom-
mended for straight-case and pistol-grip tools; reaction
bars are recommended for angle nutrunners. 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 nutrunners.
• Fingers can be crushed in open-ended crow-foot nutrun-
ners.
• Do not use in confined spaces: beware of crushing hands
between tool and workpiece, especially when unscrew-
ing.
Repetitive motion hazards
• When using a power tool to perform work-related activi-
ties, the operator might experience discomfort in the
hands, arms, shoulders, neck, or other parts of the body.
• Adopt a comfortable posture whilst maintaining secure
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 recurring
discomfort, pain, throbbing, aching, tingling, numbness,
burning sensation, or stiffness. Stop using the tool, tell
your employer and consult a physician.
Noise and Vibration hazards
• High sound levels can cause permanent hearing loss and
other problems such as tinnitus. Use hearing protection
as recommended by your employer or occupational
health and safety regulations.
