•
Be aware of buried, hidden or other hazards in your work environment. Do not contact or damage cords, conduits, pipes or hoses that may
contain electrical wires, explosive gases or harmful liquids.
Projectile hazards
•
Always wear eye protection when operating or performing maintenance on this tool. The grade of protection required should be assessed
for each use and may include impact-resistant glasses with side shields, goggles, or a full face shield over those glasses.
•
Ensure work pieces are secure. Use clamps or vises to hold work piece whenever possible.
•
Failure of the workpiece, socket, tool drive end, extension or accessories can generate high-velocity projectiles.
Noise hazards
•
Always wear hearing protection when operating this tool.
•
Exposure to high noise levels can cause permanent, disabling hearing loss and other problems, such as tinnitus (ringing, buzzing, whistling
or humming in the ears). Therefore, risk assessment and the implementation of appropriate controls for these hazards are essential.
•
Appropriate controls to reduce the risk from noise hazards may include actions such as damping materials to prevent workpieces from
"ringing".
•
If the tool has a silencer, always ensure it is in place and in good working order when the tool is being operated.
Operating hazards
•
Operators and maintenance personnel shall be physically able to handle the bulk, weight and power of the tool.
•
Keep body stance balanced and firm. Do not overreach when operating this tool. Anticipate and be alert for sudden changes in motion,
reaction torques, or forces during start up and operation. The operator should change posture during extended tasks, which can help avoid
discomfort and fatigue.
•
Use of the tool can expose the operator's hands to hazards, including crushing, impacts, cuts, abrasions and heat. Wear suitable gloves to
protect hands, however, ensure that the gloves do not restrict your ability to release the trigger or throttle mechanism.
•
To avoid accidental starting - ensure tool is in "off " position before applying air pressure, avoid throttle when carrying, and release throttle
with loss of air.
•
Do not lubricate tools with flammable or volatile liquids such as kerosene, diesel or jet fuel. Use only recommended lubricants.
•
Do not carry or drag the tool by the hose.
•
Tool and/or accessories may briefly continue their motion after throttle is released.
•
On Reversible tools, note the position of the reversing mechanism before operating the tool so as to be aware of the direction of rotation
when operating the throttle.
•
Do not use in confined spaces and beware of crushing hands between tool and workpiece, especially when unscrewing.
•
When a support handle, reaction bar or other means is provided to react torque, it should be properly installed and used to minimize the
hazard due to the reaction torque.
•
Keep clear of pinch point between reaction bar or support handles and any fixed object in the work area.
•
On tools with adjustable clutches, set the air pressure prior to setting the clutch to desired torque. Maintain this pressure during use.
•
Keep hands away from the rotating output spindle of the tube nut adapter when tool is configured for this use. A pinch point exists in this
area.
•
Fingers can be crushed in open-ended crow-foot nutrunners.
Accessory hazards
•
Use only sizes and types of accessories and consumables that are recommended by the tool manufacturer; do not use other types or sizes of
accessories or consumables.
•
Periodically check the drive end of the tool to make certain that the socket retainer functions correctly, and that sockets and drive ends are
not excessively worn which may allow the socket to come off when rotating.
•
Use only bits, sockets and adapters in good condition and that are intended for use with power tools, as poor condition or hand (chrome)
sockets or accessories can shatter and become a projectile when used with power tools.
Dust and fume hazards
•
Wear appropriate respiratory protection if dust or fumes are present in the work area.
•
Dust and fumes generated when using power tools, and existing dust disturbed by their use, can cause ill health (for example, cancer, birth
defects, asthma and/or dermatitis). Risk assessment and implementation of appropriate controls for these hazards are essential. The priority
shall be to control them at the source.
•
Direct the exhaust so as to minimize disturbance of dust in a dust-filled environment.
•
All integral features or accessories for the collection, extraction or suppression of airborne dust or fumes should be correctly used and
maintained in accordance with the manufacturer's instructions.
•
Prevent exposure and breathing of harmful dust and particles created by power tool use.
-
Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause
cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
-
lead from lead based paints,
-
crystalline silica from bricks and cement and other masonry products, and
-
arsenic and chromium from chemically treated lumber.
-
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter
out microscopic particles.
Entanglement hazards
•
Entanglement of loose clothing, personal jewelry, neckware, hair, gloves or other items can occur if not kept away from the working end of
the tool. Entanglement can result in choking, scalping, lacerations, broken bones and/or severed extremities.
•
Never hold the rotating drive, drive extension, socket or other accessory, especially when wearing gloves.
Vibration hazards
•
Power tools can vibrate in use. Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands and arms.
If you experience numbness, tingling, pain or whitening of the skin in your fingers or hands, stop using the tool and seek advice from a
qualified health professional before resuming use.
