USER MANUAL
1/2" Air Impact Wrench
JEFIW7733
Dust & Fumes
•
Dust and fumes generated when using air power tools 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.
•
R
isk assessment should include dust created by the use of the tool and the potential for disturbing existing dust.
•
Direct the exhaust so as to minimize disturbance of dust in a dust-filled environment.
•
Ensure that any dust or fumes created during operation are controlled at the point of emission
•
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.
•
Use respiratory protection in accordance with employer's instructions and as required by occupational health and safety regulations.
Noise & Vibration Levels
•
This tool may cause Hand Arm Vibration Syndrome if its use is not managed adequately.
•
This tool is subject to the vibration testing section of the Machinery Directive 2006/42/EC.
•
This tool is to be operated in accordance with these instructions.
•
Unprotected 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).
•
Risk assessment and implementation of appropriate controls for these hazards are essential.
•
Appropriate controls to reduce the risk may include actions such as damping materials to prevent workpieces from “ringing”.
•
Use hearing protection in accordance with employer's instructions and as required by occupational health and safety regulations.
•
Operate and maintain this equipment as recommended in the instruction handbook, to prevent any unnecessary increase in noise levels.
•
Select, maintain and replace any consumable parts as recommended in the instruction handbook, to prevent an unnecessary increase in noise.
•
For recommended interface dimensions for spindles and drive adapters to help reduce vibrations, please contact a Jefferson authorized sales or
service representative.
•
Exposure to vibration can cause disabling damage to the nerves and blood supply of the hands and arms.
•
Keep the hands away from the sockets during operation.
•
If you experience numbness, tingling, pain or whitening of the skin in your fingers or hands, stop using the assembly power tool for threaded
fasteners, tell your employer and consult a physician.
•
Sleeve fittings should be used where practicable.
•
Support the weight of the tool in a stand, tensioner or balancer, if possible.
•
Hold the tool with a light but safe grip, taking account of the required hand reaction forces, because the risk from vibration is generally greater
when the grip is too strong.
Note:
A health and safety assessment by the user (or employer) will need to be carried out to determine the suitable duration of use for this
equipment. Stated Vibration Emission values are type-test values and are intended to be typical. Whilst in use, the actual value will vary and can
depend on many factors which need to be taken into consideration during the assessment (factors include; the operator, the task and the working
environment, the work at hand).
Ensure that the length of leader hoses is sufficient to allow unrestricted use, as this also helps to reduce vibration.
The state of maintenance of the tool itself is also an important factor, a poorly maintained tool will also increase the risk of Hand Arm Vibration
Syndrome.
Guidance relating to the management of hand arm vibration can be found on the HSC website www.hse.gov.uk - Hand-Arm Vibration at Work.
Air Pressure Safety
•
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.
•
Ensure that cold air is directed away from the hands during operation.
•
Do not use quick-disconnect couplings. Use hardened steel (or material with comparable shock resistance) threaded hose fittings.
•
Whenever universal twist couplings (claw couplings) are used ensure that lock pins are installed and whipcheck
safety cables used to safeguard against possible hose-to-tool and hose-to-hose connection failure.
• Do not exceed the maximum air pressure stated on the tool.
• Never carry an air tool by the hose.
• Ensure that this equipment is properly maintained at all times
.
•
Check the speed and make a simple check of the vibration level after each service.
